How to Make a Tech Pack: Complete Step-by-Step Guide for Fashion Founders
A tech pack is the detailed blueprint that tells a manufacturer exactly how to cut, sew, and finish your garment. Without one, factories guess and guessing leads to wasted samples, blown budgets, and months of delays. This guide walks you through every section of a production-ready tech pack so your first sample comes back right.
What Exactly Is a Tech Pack and Why Does It Matter?
A tech pack short for technical package is the master document that communicates every detail of your garment to a manufacturer. Think of it as the architectural blueprint for your clothing. It covers everything from the shape of the neckline to the weight of the fabric to the exact placement of every label.
We have reviewed thousands of tech packs over our 20+ years in the LA Fashion District. The ones that lead to smooth production share certain qualities: they are precise, complete, and leave nothing open to interpretation. The ones that cause problems are vague, incomplete, or rely on assumptions.
"A tech pack is not paperwork it is the single most important communication tool between you and your factory. Every dollar you invest in getting it right saves five dollars in sample revisions." Maria Solano, Technical Design Director, LA Apparel Consulting Group
Here is the reality: 92% of first-sample rejections we see trace back to incomplete or unclear tech packs. That statistic comes from our own internal tracking across 1,000+ brand launches. When a founder hands a manufacturer a vague document and says "you know what I mean," the manufacturer fills in the blanks with their own defaults. Those defaults almost never match what the founder envisioned.
A garment specification sheet is sometimes used interchangeably with "tech pack," but there is an important distinction. A spec sheet typically refers to the measurement portion alone. A tech pack is the complete package sketches, materials, measurements, grading, construction details, colorways, labels, and costing all bound together.
If you are still in the early planning stages, our guide on how to start a clothing brand in 2026 covers where the tech pack fits into the broader launch timeline.
The Real Cost of Skipping or Rushing a Tech Pack
Let us talk numbers, because this is where most founders underestimate the stakes.
Average cost of a professional tech pack: $200 to $600 per style, depending on complexity.
Average cost of a single sample revision caused by a bad tech pack: $150 to $500, plus 2 to 6 weeks of lost time.
Average number of extra revisions caused by an incomplete tech pack: 2 to 4 rounds.
Here is a scenario we walk clients through at Plucky Reach regularly. A founder sends a manufacturer a document with a few flat sketches, approximate measurements, and a note that says "similar fit to Nike Sportswear hoodie." The factory builds a proto sample. The proto comes back with the wrong pocket placement, incorrect rib tension at the cuffs, a collar height that is off by half an inch, and a body length that runs two inches too long.
That is four corrections. Each correction requires a new sample. At $250 per sample round with an LA manufacturer, that is $500 to $750 in added costs and 4 to 8 weeks of delays. Overseas manufacturers add even more time. A $300 professional tech pack would have prevented every single one of those issues.
"I spent $180 on my first tech pack and thought I was being smart by doing it myself. Then I spent $1,200 on four rounds of samples fixing the mistakes. My second style, I hired a technical designer for $350. One sample round, approved. The math speaks for itself." James Okoro, Founder, Northline Essentials
According to a 2025 Techpacker industry survey, brands that use professional tech packs reduce their average sample rounds from 4.2 to 1.8 cutting their pre-production timeline nearly in half. That time savings alone can be the difference between hitting a seasonal launch window and missing it entirely.
Every Component of a Complete Tech Pack
A production-ready tech pack contains between 8 and 15 pages, depending on garment complexity. We break it into the following core sections. Each one matters, and skipping any of them creates risk.
Section 1: Cover Page and Style Overview
The cover page is the first thing a factory sees. It sets the tone for professionalism and gives the production team a quick-reference summary before they dive into the details.
Your cover page should include:
- Style name and style number (e.g., "Oversized Hoodie - PLR-HO-001")
- Season and collection (e.g., "Fall/Winter 2026, Core Collection")
- Date created and version number (e.g., "V1.0 - March 5, 2026")
- Brand name and contact information
- Colorways offered (thumbnail swatches)
- Size range (e.g., "XS through 2XL")
- A single front-view flat sketch for quick visual identification
The style numbering system matters more than founders realize. When you are managing 10, 20, or 50 styles across multiple seasons, a logical SKU structure keeps your tech packs, samples, and production orders organized. We recommend a format like BRAND-CATEGORY-NUMBER (e.g., PLR-TP-003 for your third t-shirt style).
Section 2: Technical Flat Sketches
Technical flat sketches called "flats" in the industry are precise, proportional line drawings of your garment as if it were laid perfectly flat on a table. They are not fashion illustrations. They are not mood board images. They are mechanical drawings that communicate the garment's structure.
Every flat sketch page must include:
- Front view with all design details visible
- Back view with all construction details visible
- Side view (required for garments with side panels, side zippers, or asymmetric details)
- Detail callouts zoomed-in drawings of complex areas like collars, cuffs, pockets, closures, and decorative stitching
- Interior view if the garment has a lining, hidden pockets, or inner construction
What separates a good flat from a bad one:
Software options for creating flats:
- Adobe Illustrator Industry standard. Produces clean vector flats. Learning curve is steep but the output is what factories prefer. ($22.99/month)
- Techpacker Purpose-built tech pack software with drag-and-drop templates. More accessible for non-designers. ($49/month)
- CLO 3D / Browzwear 3D garment simulation with flat export. Best for brands doing virtual sampling. ($50-$75/month)
- Canva / Figma Not built for tech packs, but capable users can produce serviceable flats for simple garments. (Free tiers available)
- Hand-drawn with ruler Acceptable if you have pattern-making training. Scan at 300+ DPI.
If you cannot create technical flats yourself, a freelance technical designer charges $50 to $200 per style for sketches alone. This is one of the highest-ROI outsourcing decisions in the entire tech pack process. For templates and more guidance, see our tech pack template guide.
Section 3: Bill of Materials (BOM)
The Bill of Materials is an exhaustive, itemized inventory of every single material that goes into your garment. Every yard of fabric. Every button. Every thread spool. Every label. Every hang tag. Every piece of interfacing and elastic.
A complete BOM uses this format:
Fabric specifications you must always include:
- Fiber content with exact percentages (80% cotton, 20% polyester not "cotton blend")
- Fabric weight in GSM (grams per square meter). For reference: 150 GSM = lightweight jersey, 280 GSM = mid-weight fleece, 400+ GSM = heavyweight fleece
- Fabric construction (single jersey, French terry, waffle knit, twill weave, etc.)
- Finish treatments (brushed, garment-dyed, enzyme washed, peached, etc.)
- Fabric width (standard is 58-60 inches for knits)
The BOM is where you control quality. Without it, the manufacturer sources whatever materials are cheapest or most available. That is how you end up with a sample that looks right but feels wrong because the factory used 180 GSM jersey when you envisioned 300 GSM heavyweight cotton.
Section 4: Measurement Specifications and Points of Measure
The measurement spec page is arguably the most critical page in your entire tech pack for clothing. It defines the exact dimensions of your garment in your base size (typically Medium for womenswear, Large for menswear).
Standard Points of Measure (POMs) for an upper-body garment:
Critical rules for measurements:
-
Always specify HOW each measurement is taken. "Chest width" measured at the armpit versus 1 inch below the armpit can differ by a full inch. Ambiguity here causes QC disputes.
-
Always include tolerances. Without tolerances, you have no agreed-upon standard for what constitutes an acceptable garment. Standard tolerances are +/- 0.25" for most measurements and +/- 0.5" for body length and sleeve length.
-
Number every POM and reference it on your flat sketch. Draw small numbered circles on your flat sketch pointing to each measurement location. The factory's pattern maker and QC team reference these numbers constantly.
-
Measure a reference garment you like. Do not guess dimensions. Find a garment with the fit you want, lay it flat, and measure every POM. Then adjust from there.
Section 5: Size Grading
Size grading defines how every measurement scales up and down across your full size range. This is where a base-size Medium becomes a complete size run from XS to 2XL.
Example grading chart for an oversized hoodie:
Grade rules (the increment between sizes):
Grading is one of the most technically demanding parts of a fashion tech pack guide. Incorrect grading produces garments that fit well in Medium but look distorted in extreme sizes sleeves too short on XL, shoulders too narrow on 2XL, body proportions off on XS.
Industry standard grading increments:
- Women's tops: 1.0" to 1.5" at chest per size
- Women's bottoms: 1.0" at waist and hip per size
- Men's tops: 1.5" to 2.0" at chest per size
- Men's bottoms: 1.0" to 1.5" at waist per size
Unless you have formal pattern-making training, we strongly recommend hiring a grading specialist for this section. In LA, a freelance grader charges $75 to $200 per style for a standard size run. That investment prevents fit disasters across your size range.
Section 6: Colorways and Color Specifications
The colorway page documents every color variation of your style, with references precise enough that a factory can match them without ambiguity.
The golden rule of color specification: never describe a color by name alone. "Forest green" means something different to every person who reads it. Color must be defined with objective standards.
Color reference systems to use:
- Pantone (PMS) codes The universal standard in fashion manufacturing. Example: PMS 19-5914 TCX (forest green). Always specify "TCX" for textile-specific Pantone colors or "TPG" for paper-based references.
- Physical lab dips / swatches For production runs, a physical swatch attached to the tech pack eliminates all remaining color ambiguity. Note in your tech pack: "Physical color standard enclosed, supersedes Pantone reference."
- Hex codes Useful for digital mockups and print materials but not precise enough for fabric dyeing on their own.
Colorway page format:
For each colorway, include:
- Colorway name and number (e.g., "CW-01: Midnight / Bone")
- Main body fabric color (Pantone reference)
- Rib/trim color (Pantone reference)
- Thread color (match or contrast, with Pantone if contrast)
- Zipper tape and teeth color
- Hardware finish (brushed nickel, matte black, antique brass)
- Label and tag adjustments per colorway (if your label changes on light vs. dark garments)
- A color-filled flat sketch showing the complete colorway
Common colorway mistakes we see at Plucky Reach:
- Specifying "color match" for thread without saying match to which component
- Not specifying zipper tape color (factories will default to their stock)
- Forgetting that rib knit dyes differently than main body fabric even in the "same" color
- Not providing separate Pantone references for each material type
Section 7: Construction and Sewing Details
Construction notes tell the factory how to assemble your garment which seam types to use, where to topstitch, how to attach trims, and what finish methods to apply. Without these notes, the factory uses their default methods, which may not match your quality or aesthetic expectations.
Construction details to specify:
- Seam types and seam allowances "All main body seams: 4-thread overlock, 3/8" seam allowance." "Side seams: safety stitch (5-thread), 1/2" seam allowance."
- Topstitch details "Hem: 1" coverstitch, 2-needle, 1/4" gauge." "Shoulder seam: single-needle topstitch, 1/8" from seamline."
- Bartack locations "Bartack at all pocket corners, all stress points. Minimum 1/2" bartack, 3/8" from edge."
- Attachment methods for trims "Drawcord: channel-inserted through front hood panel, exits through metal grommets, 5/8" from center front."
- Pressing and finishing "Final press: all seams pressed open. Garment steamed before folding."
Common seam types reference:
"Construction notes are where the difference between a $15 t-shirt and a $45 t-shirt lives. The fabric might be identical. The cut might be identical. But the seam construction, the topstitch gauge, the bartack placement that is what you feel when you wear it." David Chen, Production Manager, Pacific Coast Garment Works
If you are unsure about the right construction methods for your garment, study a comparable garment. Turn it inside out. Examine every seam. Note the stitch type, the seam allowance width, where bartacks appear, how the hem is finished. That reverse-engineering process is one of the most effective ways to write accurate construction notes.
For the most common construction mistakes to avoid, read our detailed breakdown in tech pack mistakes that cost founders thousands.
Section 8: Label and Packaging Specifications
Labels are both a branding opportunity and a legal requirement. Your tech pack must specify every label that goes into the garment, its content, its dimensions, its placement, and its attachment method.
Labels required by the FTC for US retail:
- Fiber content label Must list all fibers by percentage, in descending order (e.g., "80% Cotton, 20% Polyester")
- Care instruction label Must include care symbols and/or text for washing, drying, ironing, bleaching, and dry cleaning
- Country of origin label "Made in USA" for domestic production, or the specific country for imported goods
- Manufacturer identification Your brand name, your company's RN (Registered Number) with the FTC, or your WPL number
Label placement specifications to include:
- Main brand label: Material (woven damask, woven satin, printed satin, heat transfer), dimensions, placement (center back neck, 1/2" below neckline seam, folded under seam), attachment (sewn into neckline seam vs. topstitched)
- Care/content label: Material, dimensions, placement (left side seam, 3" above bottom hem is standard), all required content
- Size label: Integrated into care label or separate, placement, format (printed number, printed letter, woven)
- Hangtag: Dimensions, material (card stock weight), print details (1-sided or 2-sided, spot UV, foil stamp), attachment method (string, plastic barb, safety pin)
- Polybag and packaging: Bag dimensions, thickness (1.5 mil standard), suffocation warning (required by law), sticker label on bag with SKU/barcode
Label artwork: Include actual artwork files or detailed mockups for every label. Do not leave label design to the factory.
Section 9: Print, Embroidery, and Embellishment Details
If your garment includes any graphic prints, embroidery, screen printing, DTG (direct-to-garment), heat transfers, patches, or other embellishments, each one needs its own specification page.
For screen prints and graphic placements:
- Artwork file Vector format (.AI or .EPS) preferred. Minimum 300 DPI for raster.
- Print method Screen print (plastisol or water-based), DTG, sublimation, heat transfer, discharge
- Print placement Exact position referenced from a fixed point. Example: "Center chest, 3.5" below HPS, centered on body."
- Print dimensions Exact width and height. Example: "Print area: 10" wide x 8" tall."
- Ink colors Pantone references for each ink color. Number of colors (affects screen print pricing).
- Scaling across sizes Does the print size change with the garment size, or remain constant? Standard practice varies; specify your preference.
For embroidery:
- Stitch count estimate
- Thread colors (Madeira or Robison-Anton thread references)
- Backing/stabilizer type
- Maximum stitch density
Always include a placement diagram showing the print or embroidery position relative to numbered reference points on your flat sketch. "Center chest" is not specific enough. "Centered horizontally, top of graphic 3.5 inches below HPS" is specific enough.
Section 10: Cost Sheet and Target Pricing
The cost sheet is the section most first-time founders leave out and the section that makes manufacturers take you seriously as a business partner rather than a hobbyist.
A tech pack cost sheet includes:
You may not have final numbers for every line item when you first create your tech pack. That is fine. Include your best estimates and note "TBD" where you are waiting on quotes. The purpose is to demonstrate that you understand the economics and have realistic price expectations.
According to the Maker's Row 2025 Manufacturing Report, brands that include cost sheets in their tech packs receive 40% more quote responses from manufacturers because factories know they are dealing with a prepared buyer.
Want to estimate your production costs before building the cost sheet? Use our clothing cost calculator for a quick baseline.
Section 11: Fit Notes and Design Intent
This section is often informal, but we include it in every tech pack we create at Plucky Reach because it provides the factory with context that measurements alone cannot convey.
Fit notes answer the question: "What is this garment supposed to feel like on the body?"
Examples:
- "Oversized relaxed fit. Should feel roomy through the torso with dropped shoulders. The garment should not feel boxy the slight taper from chest to hem creates a modern silhouette."
- "Slim fit through the body with ease at the hip. Not skin-tight should accommodate a layer underneath."
- "Reference fit: comparable to Essentials FOG hoodie in size M. Our garment runs approximately 1 inch wider at chest and 1.5 inches longer in body."
Including a reference garment comparison is one of the most effective things you can put in a tech pack. If you can name a widely available garment and describe exactly how yours differs, the factory has an immediate point of reference.
Also include:
- Target customer demographic and body type
- Intended layering (is this worn over a t-shirt? Over a button-down?)
- Intended use context (casual streetwear, athletic performance, business casual)
Section 12: Version Control and Revision History
Every tech pack must include a version log. This is not optional it is operational insurance.
Version log format:
Version control rules:
- Never modify a tech pack without incrementing the version number. V1.0 becomes V1.1 for minor changes, V2.0 for major revisions.
- Always send the updated version to the factory with a clear note about which version supersedes the previous one.
- Keep archived copies of every version. If a QC dispute arises, you need to prove which specs were in effect at the time of production.
- The production tech pack must match the approved sample. The version used for bulk production should reflect every change made during the sampling process.
We have personally witnessed production disputes where the factory produced from V1.0 while the founder expected V2.3. A clean version log with dates and change descriptions prevents this entirely.
DIY Tech Pack vs. Hiring a Professional: Full Comparison
Here is our honest breakdown of when to do it yourself and when to bring in a professional. We tell our clients the same thing.
Our recommendation at Plucky Reach: If this is your first garment, hire a professional for at least your first tech pack. Study what they produce. Learn the format, the terminology, the level of detail. Then decide whether to DIY your second style. Many of our clients create a hybrid approach they draft the initial tech pack themselves and then pay a technical designer $100 to $200 to review and refine it.
If you are looking for clothing manufacturers suited to small brands, a professional tech pack dramatically improves your chances of getting a response and a competitive quote.
Step-by-Step Process: Building Your Tech Pack From Scratch
Here is the exact sequence we recommend to our clients. Follow it in order.
Step 1: Gather Your Reference Materials
Before you open any software, collect the following:
- A reference garment with the fit you want (buy one if needed this is a $30-$50 investment that saves hundreds)
- Inspiration images showing design details (pocket style, collar type, hem finish)
- Fabric swatches or samples of the materials you want
- Your brand assets (logo files, label artwork, Pantone colors)
Step 2: Create Your Technical Flat Sketches
Open Adobe Illustrator (or your chosen tool) and draw your front and back flats. Start with the overall silhouette, then add details: seam lines, topstitch lines, pockets, closures, labels. Add detail callout boxes for complex areas. Number each point of measure on the sketch.
Step 3: Measure Your Reference Garment
Lay your reference garment flat on a table. Measure every POM using a flexible tape measure. Record each measurement in a spreadsheet. Note where your desired garment differs from the reference ("I want 1 inch more length, 0.5 inch narrower at the cuff").
Step 4: Build Your Measurement Spec Sheet
Transfer your measurements into the tech pack format. Include the measurement description, how to measure it, the base-size dimension, and the tolerance. Cross-reference each measurement to the numbered callout on your flat sketch.
Step 5: Develop Your Size Grading
If you are producing a size run, create your grading chart. Use industry-standard grade rules as your starting point and adjust based on your fit intent. If grading is outside your skill set, hire a freelance grader this typically costs $75 to $200 per style in LA.
Step 6: Write Your Bill of Materials
Go through your garment component by component. List every material. Research specifications (GSM, fiber content, construction). Estimate yardage per unit. Get preliminary pricing from fabric suppliers. This becomes the foundation of your cost sheet.
Step 7: Specify Your Colorways
Create a colorway page for each color option. Reference every color with Pantone codes. Fill in your flat sketches with the correct colors. Specify how trim, hardware, and label colors change per colorway.
Step 8: Write Your Construction Notes
Examine your reference garment inside and out. Document every seam type, stitch type, and finishing detail. Write construction notes for every assembly step. If you are unsure about stitch terminology, consult a seam type reference guide or ask a technical designer for help.
Step 9: Prepare Your Label and Packaging Specs
Document every label: main brand label, care label, size label, hang tag. Include artwork, dimensions, placement, and attachment method. Confirm that your care label content meets FTC requirements for your fabric composition.
Step 10: Compile Your Cost Sheet
Price every BOM item. Estimate your CMT cost based on garment complexity (or request preliminary quotes from manufacturers you are considering). Calculate your target FOB, wholesale, and retail prices.
Step 11: Assemble, Review, and Finalize
Compile all sections into a clean, paginated PDF. Review every page for completeness. Have someone unfamiliar with your design read through it if they have questions, the factory will have the same questions. Assign version V1.0 and date it.
Tech Pack Software Comparison
Our take: If you are serious about building a clothing brand, invest in learning Adobe Illustrator. The $23/month pays for itself by the second style. Every manufacturer, every pattern maker, and every production partner speaks Illustrator. Techpacker is a strong alternative if you need guided structure and do not plan to learn Illustrator.
How to Send Your Tech Pack to a Manufacturer
Creating the tech pack is half the job. Sending it correctly is the other half.
Best practices for submitting your tech pack:
-
Send as a single PDF file. Do not send 12 separate image files. Not a Word document. Not a Google Drive link that requires permission. One clean, paginated PDF.
-
Name the file logically. Format: BrandName_StyleName_StyleNumber_TechPack_V1.0.pdf. Example: Plucky Reach_OversizedHoodie_PLR-HO-001_TechPack_V1.0.pdf
-
Include a cover email with key details. Restate your target MOQ (minimum order quantity), target price range, desired sample timeline, and number of colorways.
-
Attach physical swatches separately if you have them, and reference them in your email and in your tech pack.
-
Ask the factory to confirm receipt and to flag any sections that need clarification before they begin pattern-making.
According to our experience working with 100+ vetted manufacturers in LA, tech packs submitted as organized single-PDF files receive responses 60% faster than disorganized multi-file submissions. Factories process dozens of inquiries daily making their job easier makes your project a priority.
Frequently Asked Questions
What is a tech pack in fashion and why do I need one?
A tech pack is the complete technical document that tells a clothing manufacturer how to build your garment. It includes flat sketches, material specifications, measurements, size grading, colorways, construction notes, labeling details, and cost targets. You need one because no reputable manufacturer will quote, sample, or produce your garment without it. It is the universal language between designers and factories, and it is your legal and quality-control reference throughout production.
How much does it cost to make a tech pack?
If you create it yourself, your only cost is software (free to $75/month). Hiring a freelance technical designer costs $150 to $600 per style: basic garments like t-shirts and tanks run $150 to $250, moderate garments like hoodies and joggers run $250 to $400, and complex garments like structured jackets or tailored pieces run $400 to $600. Adding size grading costs an additional $75 to $200. The investment typically pays for itself by reducing sample rounds.
Can I make a tech pack without design experience?
Yes, but with caveats. For simple garments like basic tees or sweatshirts, guided tools like Techpacker make the process accessible to non-designers. For complex garments with structured construction, tailoring, or intricate details, we strongly recommend hiring a technical designer. Many founders take a hybrid approach they draft the initial version themselves and hire a professional to review and refine it for $100 to $200.
What software is best for creating a tech pack?
Adobe Illustrator is the industry standard and produces the most professional output. Techpacker is purpose-built for tech packs and more accessible for beginners. CLO 3D is excellent for brands that also do virtual sampling. For very simple garments on a tight budget, Google Docs combined with clean scanned sketches can work, though it is not ideal. Choose based on your technical skill level and how many styles you plan to produce.
How long does it take to create a tech pack?
For a first-time creator working on a simple garment, expect 15 to 40 hours across multiple sessions. For a professional technical designer working on the same garment, 4 to 8 hours. Complex garments with multiple components, construction details, and size grading take 20 to 50+ hours for a beginner. The learning curve is steep for your first tech pack but drops significantly for subsequent styles.
What is the difference between a tech pack and a spec sheet?
A spec sheet (specification sheet) typically refers specifically to the measurement and grading portion of a tech pack the pages that list garment dimensions across all sizes. A tech pack is the complete package that includes the spec sheet plus flat sketches, bill of materials, colorway specifications, construction notes, labeling details, and cost information. When a factory asks for a "spec sheet," they usually mean the full tech pack. Always provide everything.
What is the difference between a tech pack and a pattern?
A tech pack is a documentation package that tells the manufacturer what to build. A pattern is the physical or digital template that fabric is cut from during production. The manufacturer's pattern maker uses your tech pack to create the pattern. Both are needed for production, but you as the brand owner are typically responsible for the tech pack, while the factory creates the pattern. Some founders also provide patterns if they work with a separate pattern maker.
Do I need a tech pack for every style in my collection?
Yes. Every unique style requires its own tech pack. If you have a basic tee in three colorways with the same construction and fit, that is one tech pack with three colorway pages. If you have a basic tee and an oversized tee with different measurements and construction, those are two separate tech packs. Reusing sections across similar styles is efficient, but each style must have its own complete document.
How detailed should my construction notes be?
As detailed as possible. Specify every seam type, stitch type, seam allowance width, topstitch gauge, bartack location, and finishing method. If you leave a construction detail unspecified, the factory uses their default. Their default may not match your vision. Common details founders forget to specify include: seam allowance width, topstitch distance from seam, bartack placement and size, pressing instructions, and whether seams are pressed open or to one side.
What happens if my manufacturer says they do not need a tech pack?
Be cautious. Any manufacturer who says they can work from photos, verbal descriptions, or "inspiration images" alone is either inexperienced or planning to make significant interpretation calls throughout production. Those interpretation calls almost always cost you money in revisions. A professional factory will request a tech pack and if yours is well-made, they will respect you as a serious production partner. Read more about evaluating manufacturers in our guide on how to find a clothing manufacturer.
Should I include actual fabric swatches in my tech pack?
Including physical swatches is one of the best things you can do to ensure accuracy, especially for color matching and fabric hand-feel. Attach swatches to a physical copy of your tech pack or send them alongside the PDF. Note in the tech pack that "physical color standard enclosed supersedes Pantone reference for final color approval." For the digital version, include Pantone references as the documented standard.
How do I handle tech pack revisions during sampling?
After every sample review, update your tech pack with the approved changes. Increment the version number (V1.0 to V1.1 for minor changes, V2.0 for major revisions). Send the updated tech pack to the factory with a clear note about what changed. Keep copies of every version. The final production tech pack must reflect the exact specifications of your approved pre-production sample. This is your quality standard for bulk.
Can I use a clothing tech pack template instead of starting from scratch?
Absolutely. Templates save significant time, especially for your first tech pack. Start with a template that matches your garment category (tops, bottoms, outerwear, etc.), then customize every section to match your specific design. The risk with templates is leaving generic placeholder information in the final version review every field carefully before sending to a manufacturer. For template options, see our tech pack template guide.
What file format should I send my tech pack in?
Always send your tech pack as a single, paginated PDF file. Not a Word document, not a series of JPGs, not a Google Drive folder with 15 files. One PDF. Name it clearly with your brand name, style number, and version number. If you have physical swatches or samples to include, send them separately and reference them in both the tech pack and your cover email.
How many pages should a tech pack be?
A typical tech pack ranges from 8 to 20 pages depending on garment complexity. A basic t-shirt might be 8 to 10 pages. A hoodie with multiple trim details runs 12 to 15 pages. A structured jacket with lining, multiple closures, and embellishments can run 18 to 25 pages. Do not pad your tech pack with unnecessary pages, but do not cut corners either. Every section that applies to your garment must be included.
Key Takeaways: Your Tech Pack Checklist
Before you send your tech pack to any manufacturer, confirm every item on this list:
- Cover page with style name, style number, date, version, and contact info
- Front and back technical flat sketches with detail callouts
- Bill of Materials with every component specified (fabric, trim, labels, thread, packaging)
- Complete measurement spec sheet with numbered POMs, base-size dimensions, and tolerances
- Size grading chart across your full size range
- Colorway pages with Pantone references for every component
- Construction notes covering every seam, stitch, and finishing detail
- Label specifications meeting FTC requirements (care, content, origin, identification)
- Print/embroidery placement details (if applicable)
- Cost sheet with target FOB and retail pricing
- Fit notes and design intent description
- Version number and revision history
If any of those sections are incomplete or missing, your tech pack is not ready for manufacturing. Complete it before you send it the time you spend now saves multiples of that time during sampling and production.
