What Is a Tech Pack for Clothing? The Founder's Complete Guide

You've designed your garment. You have mood boards, reference images, and maybe some sketches. You contact a manufacturer, and they ask for a tech pack. You nod as if you know what that is, then immediately Google it.

You're in the right place. This guide explains exactly what a clothing tech pack is, what it contains, why manufacturers need it, and what happens to your production quality and costs if you don't have one.

Tech Pack Definition: The Short Answer

A tech pack (technical package) is a document that communicates every detail of how a garment should be made — from measurements and materials to stitching specifications and label placement. It is the blueprint your manufacturer uses to produce your clothing accurately without repeated back-and-forth.

Think of it as the architectural drawings for a building. Without them, the builder is guessing at your intentions. With them, they can execute precisely, every time, at scale.

Why Do Manufacturers Need a Tech Pack?

Manufacturers work with dozens of brands simultaneously. Without a tech pack, your production relies on verbal descriptions, WhatsApp photos, and the manufacturer's best interpretation of your "vibe." This is where expensive mistakes happen:

• Necklines cut 3cm too wide because the depth wasn't specified

• Fabric weight substituted because the correct GSM wasn't documented

• Labels sewn on the wrong side of a pocket because placement wasn't clarified

• Sleeve length wrong because "relaxed fit" meant different things to you and the pattern cutter

A tech pack eliminates ambiguity. It moves your production from "interpretation" to "execution." For low-MOQ orders, especially where you have less room for revision costs, it's the single most important document you'll prepare.

What Does a Tech Pack Include?

(The 10 Core Components)

1. Technical Sketch (Front, Back, Detail Views)

Flat technical drawings (not fashion illustration) showing exact proportions, seam lines, pocket placement, and construction details from front, back, and any relevant side or detail views. Use Adobe Illustrator or Procreate for clean, flat sketches.

2. Measurement Spec Sheet (Graded Size Chart)

Exact measurements for each critical point of measure: chest, waist, hip, length, sleeve, shoulder, armhole, etc. — graded across your size run (e.g., XS through XL). These measurements must be precise (to 0.5cm) and clearly labelled.

3. Fabric Specification

Fabric type, composition (e.g., 100% organic cotton), weight in GSM (grams per square metre), weave structure (woven/knit/plain/twill), finish (washed/unwashed, mercerised), and supplier reference if applicable.

4. Colour Specification

Pantone Colour Matching System (PMS) codes for every colour, including fabric body, thread, and any print elements. If using hand-dyed or natural-dye colours, provide physical swatch references and an acceptable tolerance range.

5. Construction Details

Stitch type and count per inch, seam allowances, hem finish, edge treatments, closure type (zip, button, tie), buttonhole size and placement, and interfacing specifications.

6. Print / Embellishment Specs

For block print, embroidery, or other surface treatments: the exact design file (vector), placement measurements, colour specification, repeat size, and any applicable technique notes (e.g., natural AZO-free dye, discharge print).

7. Trims Bill of Materials (BOM)

Itemised list of every non-fabric component: buttons (size, material, colour), zips (brand, length, type), elastic (width, stretch ratio), threads (colour code, weight), snap fasteners, D-rings, etc.

8. Label and Branding Specifications

Your brand label size and placement (neck, side seam, back waistband), care label requirements (country of origin, fibre content, wash instructions per the standards of your target market — EU/UK/US requirements differ), hangtag attachment method.

9. Packaging Specification

How the garment should be packaged for shipping: folded or hanging, polybag size and type, tissue wrap, carton specifications, packing quantities per carton.

10. Quality Standard Notes

Acceptable defect tolerance, key quality checkpoints (seam strength, print registration, button pull-test), and any market-specific compliance requirements (e.g., REACH compliance for EU, CPSC for USA children's clothing).

Do You Absolutely Need a Tech Pack?

Q: Can I place a manufacturing order without a tech pack?

Yes — some manufacturers (including Ashanari) will work from detailed sketches and reference samples if you don't have a formal tech pack. However, the risk of revision rounds and interpretation errors is significantly higher, and revision costs add up quickly. For first-time orders or complex garments, a tech pack will save you more than it costs to create.

Q: How do I create a tech pack if I'm not a designer?

Several options: (1) Hire a freelance technical designer on Upwork or Fiverr (budget £150–£500 per style depending on complexity); (2) Use tools like Techpacker, NuOrder, or even well-structured Excel/Google Sheets templates; (3) Use a manufacturer who offers tech pack development as a service. Ashanari offers tech pack development support as part of our pre-production services — we help brands who know what they want but don't have the technical documentation to express it.

Q: How long does it take to create a tech pack?

For an experienced technical designer: 4–12 hours per style, depending on complexity. For a first-timer: 1–3 days per style. Building time into your pre-production timeline for tech pack creation is important — the weeks you spend getting the document right will save you weeks of production revision.

Tech Packs and Low MOQ Production

For low-MOQ orders, tech packs are especially critical. When you're ordering 50 or 100 units, a single revision round adds cost and time that represents a significant percentage of your total investment. A clear tech pack reduces revision probability from (industry average) 2.8 rounds to under 1 round.
