Tech Pack Template: Create a Professional Tech Pack (Free Guide)
Tech Pack Template: Create a Professional Tech Pack (Free Guide)
A tech pack template is a structured, multi-page document that communicates every technical detail of your garment flat sketches, measurements with tolerances, fabric specifications, trim details, colorways, construction notes, and labeling to your manufacturer. Without a complete tech pack, no reputable factory will quote your product, and incomplete tech packs are the single most expensive mistake we see across 1,000+ brand launches.
Why This Guide Exists (And Why Most Templates Online Are Incomplete)
If you search "tech pack template" right now, you will find dozens of free downloads. Most of them are one- or two-page worksheets that cover maybe 30% of what a manufacturer actually needs. We know this because we see the results: founders walk into our LA Fashion District office every week with "completed" tech packs that are missing tolerances, have no bill of materials, specify fabrics by name instead of technical specification, and include fashion illustrations instead of technical flats.
The factory receives this document, sends back questions the founder cannot answer, and the project stalls for weeks before a single sample is cut.
We have reviewed and corrected tech packs for more than 1,000 clothing brand launches over the past two decades. We have watched the same gaps cause the same problems re-samples, cost overruns, production delays, garments that come back wrong hundreds of times. This guide is the fix.
We are going to walk you through every section of a professional tech pack, explain what each section must contain and why the factory needs it, show you comparison tables for software options, and give you the framework to either build your own tech pack or evaluate whether hiring a professional makes more financial sense.
If you are starting a clothing brand and preparing to approach manufacturers, this is the document that determines whether that conversation goes well or badly. Let's get it right.
What Is a Tech Pack? (And What It Is Not)
A tech pack short for "technical package" is the complete set of technical documents a manufacturer uses to produce your garment. Think of it as a blueprint. An architect does not tell a construction crew to "build a nice house." They hand them a set of engineered drawings with exact dimensions, material specifications, and construction details. A tech pack does the same thing for clothing.
A complete tech pack typically runs 8-15 pages per style, depending on complexity. A basic t-shirt might need 8 pages. A lined jacket with multiple pockets, custom hardware, and specialty finishes might require 20+.
Here is what a tech pack is NOT:
- Not a mood board. Mood boards communicate aesthetic direction. Tech packs communicate construction instructions.
- Not a fashion illustration. Fashion illustrations are stylized and proportionally exaggerated. Tech packs use flat technical sketches drawn to accurate scale.
- Not a verbal description. "Make it like this photo but with longer sleeves" is not a tech pack. It is a conversation that will cost you $300-$800 in wasted samples.
- Not a spec sheet alone. A garment specification sheet (the measurement page) is one component of a tech pack, not the whole document.
"I tell every founder the same thing: your tech pack is your contract with the factory. Everything in that document is what they will build. Everything not in that document is what they will guess. And factory guesses cost you money every single time." Marco Reyes, Production Manager, LA Garment District (18 years)
When a manufacturer asks for your "tech pack," they expect the complete package. When they ask for a "spec sheet," they usually still mean the complete package. Always send everything.
Why Manufacturers Require Tech Packs (The Business Case)
Some founders treat the tech pack as bureaucratic overhead a hoop to jump through before the factory will work with them. This is the wrong way to think about it. The tech pack exists because manufacturing is a precision operation, and ambiguity at any point in that operation creates financial consequences for both parties.
Here is the business case in concrete numbers:
The cost of a missing or incomplete tech pack:
- Each sample round in Los Angeles costs $150-$500 for standard garments and $500-$1,500+ for complex construction
- An incomplete tech pack adds an average of 1.5-2.5 additional sample rounds per style
- At $300 per round, that is $450-$750 in avoidable costs per style
- Across a 5-style collection, you are looking at $2,250-$3,750 in wasted sampling alone
- Timeline impact: 3-6 additional weeks per sample round
The cost of a complete tech pack:
- Professional tech pack creation: $150-$600 per style (depending on complexity)
- DIY time investment: 8-20 hours per style (if you know what you are doing)
- ROI: 3-5x the investment in avoided re-samples and production corrections
We have tracked this across our client base. Founders who submit complete, professional tech packs to manufacturers average 1.2 sample rounds before approval. Founders who submit incomplete tech packs average 3.4 sample rounds. The math is not subtle.
"When I receive a clean tech pack with proper measurements, tolerances, and a complete BOM, I can quote accurately in 24-48 hours and produce a first sample that is 90% correct. When I receive a sketch and some notes, I have to spend a week asking questions before I can even start. Most of those founders think I am being slow. I am being thorough because they were not." Sandra Velasquez, Owner, Custom Cut & Sew Manufacturing, Los Angeles
If you need help finding the right manufacturer for your project, a strong tech pack is the first thing they will evaluate when deciding whether to take on your brand.
The Complete Tech Pack Template: Every Section Explained
A professional tech pack contains 10 core sections. Some garments require all 10. Some simpler garments can combine sections or omit one or two. But you should understand all of them so you can make informed decisions about what your specific garment needs.
Here is the complete section breakdown:
Let's break down each section in detail.
Section 1: Cover Page and Header Information
Every tech pack starts with a cover page. This is simpler than it sounds, but it must include specific information:
- Style name: The internal name you use for this garment (e.g., "Westside Hoodie")
- Style number: A unique identifier code (e.g., "WS-HD-001"). Every garment needs a style number. This is how the factory tracks it.
- Season/Collection: Which season or collection this style belongs to (e.g., "Fall/Winter 2026")
- Date created: The original creation date of the tech pack
- Revision number: Critical for version control. Start at Rev 1. Every time you update the tech pack, increment the revision number. Factories work from the most recent revision, and confusion between revisions causes production errors.
- Designer/Brand contact: Name, email, phone number
- Garment category: T-shirt, hoodie, jacket, pants, etc.
This seems basic, but 40% of the tech packs we review at Plucky Reach are missing a revision number. When a founder sends three rounds of updates and the factory is working from version two of four, every correction in versions three and four gets lost.
Section 2: Technical Flat Sketches
Technical flat sketches called "flats" are the visual backbone of your tech pack. They are not fashion illustrations. They are precise, proportional, line-drawn diagrams of your garment shown as if laid flat on a table, with no body inside.
What your flats must include:
- Front view (full garment)
- Back view (full garment)
- Side view (if the garment has side details like seaming, pockets, or panels)
- Interior view (if lined or if interior construction matters)
- Detail callouts for complex areas: collar construction, cuff detail, pocket shape, zipper placement, button spacing, hem finish
What makes flats "technical" rather than "artistic":
- Drawn to accurate proportion (not elongated fashion proportions)
- Every seam line is visible and accurate
- Topstitching shown with dashed lines
- Hardware (buttons, snaps, zippers, grommets) drawn in correct position
- Symmetry is precise
- Line weight is consistent
Flats can be created in Adobe Illustrator (industry standard), CorelDRAW, or dedicated tech pack software. Hand-drawn flats are acceptable if they are precise and scannable, but digital flats are strongly preferred because they are easier to update and communicate more clearly.
A flat for a basic crew neck t-shirt might take 1-2 hours to create digitally. A flat for a multi-pocket utility jacket with hood and interior lining might take 6-10 hours.
Section 3: Bill of Materials (BOM)
The Bill of Materials is arguably the most important page of your tech pack for costing purposes. It lists every single material that goes into the finished garment, with technical specifications for each.
A complete BOM includes:
Every item on the BOM needs to be specific enough that the factory can source the exact material or an equivalent. "Black zipper" is not a BOM entry. "YKK #5 Vislon, 26 inches, separating, black tape, matte black teeth" is a BOM entry.
Our data from working with LA manufacturers shows that BOM errors account for 35% of all first-sample rejections. The most common BOM error: unspecified zipper brand and type, resulting in the factory substituting a cheap generic zipper that fails quality testing.
Section 4: Colorways
The colorway section defines every color option for your garment using universal color references primarily Pantone Textile (TPX/TCX) codes.
Why Pantone codes matter:
Your "navy blue" and the factory's "navy blue" are not the same color. Even if they look the same on your screen. Screens are not calibrated to production dyes, and verbal color descriptions are meaningless in manufacturing.
What your colorway section must include:
- Pantone TPX/TCX code for every color in every colorway
- A flat sketch showing each colorway with colors mapped to garment sections
- Color specifications for all trims (zipper tape, buttons, thread, elastic, drawcord) in each colorway
- Notes on any special dye processes (garment dye, pigment wash, enzyme wash, acid wash)
Example colorway chart:
If you are working with custom dye lots (common for garment-dyed products), specify whether the Pantone code is a target that allows tolerance or a hard match requirement. Hard matching costs more and takes longer.
Section 5: Measurement Spec Sheet (Garment Specification Sheet)
This is the section most people think of when they hear "garment specification sheet." It is also the section where the most expensive errors occur.
Your measurement spec sheet defines every measurable dimension of the garment, organized by point of measure, across all sizes you intend to produce.
Critical elements of a professional spec sheet:
-
Point of Measure (POM) diagram: A flat sketch with numbered measurement points and arrows showing exactly where each measurement is taken. There should be zero ambiguity about where the tape measure starts and ends.
-
Base size measurements: The complete dimension set for your sample size (usually M or L for menswear, S or M for womenswear).
-
Graded measurements: How each dimension changes across your full size range (XS through XXL, or whatever range you produce).
-
Tolerances: The acceptable deviation range for each measurement, expressed as +/- values.
Example spec sheet structure (crew neck t-shirt):
Common measurement spec mistakes (and their cost):
- Missing tolerances: factory applies their own, sample comes back wrong. Re-sample cost: $150-$400.
- Measuring "on body" vs. "laid flat" confusion: a 42" chest on-body is a 21" laid-flat measurement. Confusing the two doubles your garment width. We have seen this happen. The sample came back wearable as a tent.
- No grading increments specified: factory guesses how to scale between sizes. The XL fits like an L-and-a-half.
Section 6: Construction and Sewing Notes
Construction notes tell the sewing floor exactly how to assemble your garment. This is where you specify stitch types, seam types, seam allowances, and the order of operations.
Stitch type specification:
The apparel industry uses standardized stitch codes from ASTM International (formerly the Federal Stitch Classification). The most common:
Seam allowance specification:
Seam allowances define how much fabric extends beyond the stitch line. Standard allowances:
- Side seams: 1/2" to 5/8" (most common)
- Hem: 1" to 1.5" for standard hems; 1/4" to 3/8" for coverstitch hems
- Neckline: 1/4" to 3/8"
- Armhole: 3/8" to 1/2"
What your construction notes must specify:
- Stitch type for every seam (not just "sewn together")
- Stitches per inch (SPI) industry standard is 10-12 SPI for most garments
- Seam allowance for every seam type
- Topstitch distance from edge where applicable
- Bar tack locations (stress points: pocket openings, fly, belt loops)
- Any special operations: flat-felled seams, French seams, binding, piping
If your garment has complex construction set-in sleeves, welt pockets, an interior storm flap include a close-up detail drawing for each complex area with its own stitch and construction callouts.
Section 7: Artwork, Print, and Embellishment Placement
If your garment includes any printed, embroidered, or applied graphics, this section provides the factory (and their screen printer or embroiderer) with everything they need to execute accurately.
For screen printing / DTG / heat transfer:
- Print location on garment (exact measurement from HPS, center front, or other reference point)
- Print dimensions (width x height)
- Number of colors
- Pantone color references for each color in the print
- Print method specified (screen print, DTG, heat transfer vinyl, sublimation)
- High-resolution artwork file (300 DPI minimum, vector preferred)
- Separate artwork file for each colorway if print colors change
For embroidery:
- Stitch count estimate
- Thread colors (Madeira or Isacord color codes preferred)
- Backing type (cutaway, tearaway, water-soluble)
- Embroidery area dimensions
- Digitized file (.dst or .emb format)
For woven patches, rubber labels, or other applied elements:
- Attachment method (sewn, heat-sealed, adhesive)
- Exact placement with measurements
- Separate spec sheet for the patch/label itself
A missing print placement measurement is one of the most common tech pack errors we encounter. "Center chest" is not specific enough the factory needs to know how many inches down from the high point of the shoulder and whether "center" means geometric center of the garment front or optically centered (which accounts for the visual weight of the neckline).
Section 8: Labels and Packaging
Labels and packaging are the final production details, and they have both legal and branding requirements.
Required labels (for the US market):
- Care label: Fiber content, country of origin, care instructions (FTC-required). Must follow ASTM D5489 care symbol standards.
- Brand label: Your brand name/logo, usually at center back neck or side seam
- Size label: Can be integrated into the care label or brand label, or separate
Optional labels:
- Content label (fiber breakdown)
- Hang tags (brand storytelling, pricing)
- Barcode / UPC label
- "Made in USA" or origin-specific label (if applicable and legally accurate)
What your label section must specify:
- Label type (woven, printed, heat transfer)
- Label size (width x height when folded, if applicable)
- Label placement (center back neck, 2" below neckline seam, etc.)
- Label artwork (supplied separately or designed by manufacturer)
- Fold type (end fold, center fold, mitre fold, straight cut)
Packaging specifications:
- Folding method (retail fold, roll, flat pack)
- Tissue paper (yes/no, branded/unbranded)
- Poly bag dimensions
- Sticker seals or branded tape
- Hang tag attachment (string, plastic barb, safety pin)
For details on US labeling compliance, make sure your legal requirements are covered before production.
Section 9: Fabric and Trim Detail Pages
While the BOM lists every material, the fabric and trim detail section goes deeper. This is where you provide the factory with the information they need to source or verify materials.
For each fabric:
- Full technical name (e.g., "14oz Right-Hand Twill Selvedge Denim, 100% Cotton, Raw/Unwashed")
- Weight in GSM (grams per square meter) or oz/yard
- Width (cuttable width, not total roll width)
- Fiber content with exact percentages (e.g., "97% Cotton, 3% Elastane" not "cotton with a little stretch")
- Construction type (jersey, interlock, rib, twill, satin, etc.)
- Finish (brushed, enzyme-washed, peached, sanforized, mercerized)
- Shrinkage allowance (pre-shrunk? If not, expected shrinkage percentage)
- Physical swatch reference (whenever possible, attach or send a physical swatch)
For each trim:
- Supplier name and item number (if sourced)
- Physical sample reference
- Technical drawing or photo
- Quantity per garment
- Color per colorway
Having exact fabric specifications prevents one of the most frustrating manufacturing problems: the factory substituting a "similar" fabric because your spec was vague. "Similar" in fabric can mean a 40 GSM weight difference, a different hand feel, a different drape, and a different shrinkage rate. None of these are visible in a photo. All of them are noticeable in the finished garment.
Section 10: Grading Specifications
Grading determines how your garment scales across sizes. Your base size measurements are the starting point, and the grading spec defines the incremental change for each measurement at each size jump.
Example grading increments (menswear t-shirt, S-XXL):
Note that grading is not always uniform. The jump from L to XL and XL to XXL is often larger than S to M for chest and hem measurements. This accounts for the proportional difference in body types at larger sizes.
If you do not provide grading, the factory will apply their own standard grading rules, which may not match your fit intent. Grading errors are some of the hardest to catch until you are fitting samples across your full size range which many founders skip, only to discover in production that their XL fits like an L.
Tech Pack Software and Tools Comparison
You have three main paths for creating a tech pack: dedicated tech pack software, general design software, or spreadsheet templates. Here is an honest comparison based on what we have seen our clients use successfully.
Techpacker
Techpacker is a dedicated tech pack creation platform built specifically for the apparel industry. It provides templates, built-in measurement tables, BOM management, and collaboration tools. The interface is designed for people who are not technical designers.
Pros: Purpose-built for tech packs, library of templates, easy to share with manufacturers, version control built in, comment and annotation tools for collaboration.
Cons: Monthly subscription cost, less flexibility than Illustrator for custom flat sketches, some manufacturers prefer receiving Illustrator files.
Adobe Illustrator + Excel
This is the industry standard combination. Technical designers at major brands use Illustrator for flats and Excel (or Google Sheets) for measurement specs and BOM tables.
Pros: Maximum flexibility and quality, universally accepted by manufacturers, precise vector-based flat sketches, scales to any complexity.
Cons: Illustrator has a significant learning curve for non-designers. Creating professional flats requires both software proficiency and garment construction knowledge. This combination is best if you have design experience or are hiring a freelance tech pack designer.
Google Sheets / Excel Templates
Free spreadsheet templates can work for the data-heavy portions of a tech pack (measurements, BOM, colorways), but they cannot produce technical flat sketches.
Pros: Free, accessible, easy to edit, good for iterating on measurements and materials.
Cons: No flat sketch capability (you will need to create flats separately), formatting can be inconsistent, less professional presentation, some manufacturers find them harder to work from than a formatted PDF.
Hiring a Freelance Tech Pack Designer
If your time is more valuable than $150-$600 per style, or if you do not have the technical knowledge to create a complete tech pack yourself, hiring a professional tech pack designer is often the most cost-effective option.
Where to find tech pack designers:
- Freelance platforms (Upwork, Fiverr quality varies enormously; vet carefully)
- Fashion-specific freelance networks
- Local fashion schools (recent graduates, lower cost, less experience)
- Consulting firms like Plucky Reach that offer tech pack creation as part of launch services
What to look for:
- Portfolio of completed tech packs (not just flat sketches)
- Experience with your garment category (a knitwear tech pack specialist is not ideal for tailored jackets)
- Understanding of manufacturing (not just design)
- Clear revision policy (how many rounds of changes are included)
DIY Tech Pack vs. Hiring a Professional: The Real Cost Comparison
This is the question every founder asks. Here is the honest breakdown based on what we have tracked across our client base.
The pattern is clear: founders who invest in professional tech packs spend less total money, even after accounting for the creation cost, because they dramatically reduce re-sampling.
That said, there are legitimate reasons to DIY:
- You have design or technical design training. If you can create accurate flats and understand garment construction, DIY makes sense.
- You are learning the process. Creating your own tech pack teaches you more about garment construction than almost any other exercise. The knowledge is valuable even if the first tech pack needs work.
- Budget is genuinely zero. If you truly cannot afford $150-$600, a DIY tech pack is better than no tech pack. Just be prepared for additional sample rounds.
"The founders who save the most money are the ones who learn tech pack fundamentals so they understand what they are looking at and then hire a professional to execute. They can evaluate the work, communicate changes efficiently, and catch errors before the factory does. That combination is unbeatable." Diana Melendez, Senior Fashion Consultant, Plucky Reach

The 7 Most Common Tech Pack Template Mistakes
After reviewing tech packs from over 1,000 brand launches, we have identified the errors that appear most frequently and cost the most money. If you are building your own tech pack, check every one of these before you send it to a manufacturer.
Mistake 1: Using Fashion Illustrations Instead of Technical Flats
Fashion illustrations are beautiful. They are also useless for manufacturing. An elongated, stylized figure with exaggerated proportions tells the factory nothing about actual garment dimensions, seam placement, or construction details. We estimate 25% of first-time founders submit fashion illustrations as their "technical sketches." Every one of them requires a redo before manufacturing can begin.
Mistake 2: Listing Fabric by Name Instead of Technical Specification
"French terry" is not a spec. "320 GSM, 80% Cotton / 20% Polyester, brushed back French terry, 60 inch width, jet black Pantone 19-4007 TCX" is a spec. Fabric names describe a category. Technical specifications define the exact material.
Mistake 3: Missing Tolerances on Measurements
We covered this in the measurement section, but it bears repeating because it is the single most common spec sheet error. Every measurement needs a +/- tolerance. Without it, the factory defines "close enough" on their terms.
Mistake 4: No Revision Number or Date
When you update a tech pack (and you will update it), the factory must know which version they are working from. We have seen production runs built from Rev 2 of a tech pack when the founder had sent Rev 4. The result was $8,000 in garments built to outdated specs.
Mistake 5: Incomplete or Missing BOM
If your BOM does not list the specific zipper, the specific thread, the specific elastic, the factory will substitute. Their substitution will be whatever is cheapest or most readily available. This is not malicious it is practical. They cannot wait for you to decide. Specify everything, or accept what you get.
Mistake 6: No Construction Details
"Sew the sleeves on" is not a construction note. How are the sleeves attached? Set-in? Raglan? Drop shoulder? What stitch type? What seam allowance? Is the seam taped, serged, or flat-felled? Construction notes are what separate a $15 garment from a $45 garment, and the factory will default to the fastest (cheapest) method unless you specify otherwise.
Mistake 7: Ignoring Labels and Packaging
Labels and packaging are legally required (care labels, fiber content, country of origin) and brand-critical (the unboxing experience). Founders who leave this section blank get generic labels and no-frills poly bags. Your brand label is the last detail the customer sees before wearing your garment. Specify it.
How Much Does a Professional Tech Pack Cost in 2026?
Here is what you should expect to pay, based on current market rates in the Los Angeles Fashion District and nationally:
What affects the price:
- Number of flat sketch views required
- Number of colorways
- Size range (more sizes = more grading)
- Construction complexity
- Whether artwork/prints are included
- Number of revision rounds included
- Whether the designer sources fabric/trim specs or you provide them
Red flags in tech pack pricing:
- Under $75 for any garment: likely a template fill-in with no original flat sketches
- No revision rounds included: you will pay extra for every change
- "Unlimited revisions": usually means the designer expects the project to stall
- Per-page pricing: incentivizes padding the document rather than clarity
If you are comparing tech pack costs against your overall launch budget, our guide on startup costs breaks down every expense category.
Step-by-Step: How to Create Your Tech Pack from a Template
If you are going the DIY route, here is the process we recommend based on what produces the best outcomes with manufacturers.
Step 1: Start with your base garment reference. Find a garment that is closest to what you want to create. Measure it completely. These become your starting measurements.
Step 2: Create your technical flat sketches. Use Adobe Illustrator, Techpacker, or hire a freelancer for this step only (often $50-$100 for basic flats). Ensure front, back, and all necessary detail views are included.
Step 3: Build your measurement spec sheet. Start with your base garment measurements. Adjust for your design intent. Add tolerances to every measurement. Grade across your size range.
Step 4: Complete the Bill of Materials. Research and specify every fabric, trim, and component. Include supplier references if you have them. Be technically specific.
Step 5: Define your colorways. Get Pantone references for every color. Specify how colors apply to each component of the garment.
Step 6: Write your construction notes. If you are not confident in stitch and seam specifications, study the base garment you measured in Step 1. Look at how it is constructed. Note the stitch types, seam allowances, and finishing methods.
Step 7: Add labels, packaging, and artwork. Specify your label types, placements, and content. Define packaging requirements. Include any print or embroidery artwork with placement specs.
Step 8: Review against manufacturer requirements. Before sending, ask your manufacturer if they have a preferred tech pack format. Some factories have their own templates and prefer you fill in their format. Others accept any format as long as it is complete.
Step 9: Send as a formatted PDF. Always send tech packs as PDF. Do not send editable files (they get accidentally modified). Keep your editable master file for revisions.

What Manufacturers Actually Look at First (Insider Perspective)
We have asked dozens of production managers at LA garment manufacturers what they evaluate first when they receive a tech pack. Here is the consistent answer:
First: the flat sketch. Can they understand what the garment is? Is it clear enough to mentally construct? If the flat is confusing or ambiguous, many factories will stop here and ask for clarification before reviewing anything else.
Second: the BOM. Can they source these materials? Are the specs specific enough to quote? Are there custom items (custom hardware, custom fabric) that will affect lead time?
Third: the measurements. Are they complete? Do they have tolerances? Are the grading increments reasonable? A production manager can spot unrealistic measurements in seconds a 15" chest width on a men's medium, for example, signals that the founder does not understand measurement conventions.
Fourth: construction notes. Are there any complex operations that require specialized machinery? Will this garment require more sewing stations than a standard piece? These factors directly impact pricing.
What they ignore: pretty formatting, mood board images, brand story pages, marketing language. The tech pack is a technical document. Treat it as one.
Industry Statistics: Why Tech Packs Matter (By the Numbers)
We have compiled these statistics from our own client tracking data and industry research:
-
72% of first-sample rejections are caused by tech pack errors or omissions not factory mistakes. The factory built exactly what the tech pack described; the tech pack described the wrong thing. (Plucky Reach internal data, 2024-2026, 1,000+ styles tracked)
-
Brands that submit complete tech packs receive first samples an average of 11 days faster than brands that submit incomplete packs. The gap is entirely due to the back-and-forth clarification process that incomplete packs require. (Plucky Reach client tracking, 2025-2026)
-
The average first-time founder spends $1,850 more on sampling than necessary due to tech pack deficiencies across their first collection. For a 5-style collection, that represents a 23% increase over the expected sampling budget. (Plucky Reach financial analysis, 2025)
-
Manufacturers are 3.2x more likely to accept a new client who submits a professional tech pack versus one who submits an incomplete package or "design brief." Quality factories are selective about their clients, and your tech pack is your first impression. (Survey of 47 LA-based cut-and-sew manufacturers, Plucky Reach , 2025)
-
89% of production-stage errors that result in full-batch rejection trace back to a tech pack deficiency rather than a manufacturing process failure. The remaining 11% are genuine factory errors (machine malfunction, operator error, material defects). (Plucky Reach quality audit data, 2023-2025)
These numbers underscore a point we make to every founder: the tech pack is not paperwork. It is the foundation of your entire manufacturing relationship, and the quality of your tech pack directly determines the quality and cost of your finished product.
Frequently Asked Questions
What is a tech pack in fashion?
A tech pack (technical package) is a multi-page document that provides a clothing manufacturer with every detail needed to produce your garment. It includes technical flat sketches, a bill of materials, measurement specifications with tolerances, colorway definitions, construction and stitch notes, label and packaging details, and artwork placement. It is the industry-standard communication tool between a designer and a factory. Without one, no reputable manufacturer will begin sampling or production.
Can I make a tech pack in Excel or Google Sheets?
You can create the data-heavy portions of a tech pack measurement specs, BOM, colorway charts, grading tables in Excel or Google Sheets. However, you cannot create technical flat sketches in a spreadsheet. You will need a separate tool (Adobe Illustrator, Techpacker, or a hired freelancer) for the flat drawings. Some founders create their flats separately and paste them into a spreadsheet-based template. This works, but ensure the final document is exported as a clean, well-formatted PDF before sending to a manufacturer.
How many pages should a tech pack be?
A complete tech pack typically runs 8-15 pages per style. A basic garment (t-shirt, tank top) might require 8-10 pages. A moderately complex garment (hoodie, button-up shirt) usually needs 10-14 pages. A complex garment (lined jacket, tailored blazer, technical outerwear) can require 15-25 pages. Page count is less important than completeness a 6-page tech pack that covers everything is better than a 20-page tech pack that is padded with unnecessary mood board images.
What software do professional tech pack designers use?
The industry standard is Adobe Illustrator for flat sketches and technical drawings, combined with Excel or a purpose-built tool for measurement tables and BOM. Dedicated platforms like Techpacker provide an all-in-one solution. CLO 3D and Browzwear are used for 3D garment visualization but are not replacements for a traditional tech pack they supplement it. Major brands use PLM (Product Lifecycle Management) systems like Centric or Gerber Yunique, but these are enterprise tools not suited for startup brands.
How long does it take to create a tech pack?
For a first-time founder creating their own tech pack, expect 15-40 hours per style, depending on complexity and your familiarity with the process. That time drops significantly with experience an experienced technical designer can complete a basic tech pack in 4-8 hours and a complex one in 8-16 hours. If you hire a professional, your time investment is typically 2-5 hours of briefing and revision review per style.
Do I need a tech pack for a t-shirt?
Yes. Even a basic t-shirt requires a tech pack. The measurements, fabric weight, neck finish, hem style, sleeve length, fit silhouette, label placement, and print specifications all need to be documented. A t-shirt tech pack is simpler and shorter than a jacket tech pack, but it is still required. In fact, because t-shirts seem "simple," founders often skip the tech pack and discover that their "basic" t-shirt comes back with the wrong fit, wrong fabric weight, wrong neck ribbing, and wrong hem finish.
What is the difference between a tech pack and a spec sheet?
A spec sheet (specification sheet) is one component of a tech pack. It specifically refers to the measurement specification page the document that lists all garment dimensions, graded across sizes, with tolerances. A tech pack is the complete package that includes the spec sheet plus flat sketches, BOM, colorways, construction notes, labels, packaging, and artwork placement. When manufacturers ask for a "spec sheet," they often mean the complete tech pack. Always clarify, and always send the complete package.
How much does it cost to have a tech pack made?
Professional tech pack creation typically costs $150-$600 per style for freelance designers, $200-$1,000 per style for agencies or specialized services, and varies widely for full-service consulting packages that bundle tech packs with brand launch services. Cost depends on garment complexity, number of colorways, size range, and whether flat sketches need to be created from scratch or you already have them. A 5-style collection from a mid-range freelancer typically costs $1,000-$3,000.
Can I use photos instead of flat sketches?
No. Photos (including inspiration images from Instagram, Pinterest, or other brands) are not substitutes for technical flat sketches. Photos show garments on bodies with drape, shadow, and perspective distortion. They do not show accurate proportions, construction details, or internal structure. A manufacturer can use a reference photo as supplementary context to understand the general aesthetic you are going for but they cannot build from it. Always provide technical flats.
What is a BOM in a tech pack?
BOM stands for Bill of Materials. It is the complete list of every material, component, and trim that goes into your finished garment: shell fabric, lining fabric, interlining, thread, zippers, buttons, snaps, elastic, drawcords, labels, hang tags, packaging materials, and any other component. Each item on the BOM must include technical specifications (fiber content, weight, color, size, supplier, etc.). The BOM is what the factory uses to source materials and calculate your garment cost.
Do manufacturers have their own tech pack templates?
Some manufacturers do provide their own tech pack templates and prefer that clients fill them in. This is actually a positive sign it means the factory has standardized their intake process and knows exactly what information they need. If your manufacturer provides a template, use it. Transfer your specifications into their format. If they do not provide one, submit your tech pack in a clean PDF format using the structure outlined in this guide.
What are Pantone codes and why do I need them for my tech pack?
Pantone codes are standardized color references used across the textile, printing, and manufacturing industries. A Pantone code (e.g., "Pantone 19-4007 TCX") defines a specific color that can be universally matched across different materials and production facilities. In your tech pack, Pantone codes eliminate subjective color interpretation. Without them, your "navy blue" might be the factory's "dark royal" or "midnight." For textiles, use Pantone TCX (textile cotton) or TPX (textile paper) codes. Pantone color guides can be purchased from Pantone's website, and many design software programs include Pantone libraries.
How do I create grading for my tech pack?
Grading defines how each garment measurement changes from size to size. Start with your base size measurements (usually M for womenswear or L for menswear). Then define the increment (or "grade rule") for each measurement at each size jump. Standard grading increments vary by garment type and market a 1" chest grade per size is common for casual menswear, while a 1.5" grade might be standard for plus-size ranges. If you are unsure about grading, study comparable garments from established brands in your market segment, measure multiple sizes, and calculate the increments. Alternatively, a professional pattern maker or tech pack designer can develop your grading rules.
Should I include a physical swatch with my tech pack?
Whenever possible, yes. A physical fabric swatch gives the manufacturer a tactile reference that no digital specification can fully replace. They can feel the hand (softness, drape, body), see the true color under neutral lighting, and assess the surface texture. When sending your tech pack digitally, note in the BOM that a physical swatch is available and will be mailed or delivered. When meeting a manufacturer in person for example, visiting LA Fashion District factories always bring swatches. A 6"x6" swatch per fabric is the minimum useful size.
What happens if my tech pack has errors?
Errors in your tech pack translate directly into errors in your samples and potentially your production run. If the error is caught during sampling (the best case), you will pay for an additional sample round ($150-$500+ per round) and lose 2-4 weeks of timeline. If the error is not caught until production, the consequences are far more severe: an entire production batch may be incorrect, and recovery options are limited and expensive. This is precisely why we encourage founders to either invest in professional tech pack creation or thoroughly review their DIY tech pack against a comprehensive checklist before submitting it. For a detailed guide on the most common errors, see our post on tech pack creation.
Your Next Steps
If you have read this far, you understand what a tech pack requires and why it matters. Here is how to move forward:
If you are DIY-ing your tech pack: Use the section-by-section framework in this guide as your checklist. Do not skip sections. Do not leave measurements without tolerances. Do not use vague fabric descriptions. Export as PDF. Have someone with manufacturing experience review it before you send it to a factory.
If you are hiring a professional: Use this guide to evaluate the work you receive. You now know what every section should contain. If your hired designer delivers a tech pack missing a BOM, missing tolerances, or with fashion illustrations instead of technical flats, send it back.
If you need help deciding: We offer free strategy calls where we review your project scope and recommend whether DIY or professional tech pack creation makes more sense for your specific situation, collection size, and budget.
If you are ready to launch: Our brand launch program includes professional tech pack creation, manufacturer matching from our vetted network of 100+ LA factories, and hands-on production management. We have done this more than 1,000 times, and we know exactly how to get your garment from concept to finished product without the costly detours.
Your tech pack is the foundation. Build it right, and everything downstream sampling, production, quality, costs gets easier. Build it wrong, and you will spend months and thousands of dollars fixing problems that should never have existed.
Build it right.
