How to make a tech pack for garment manufacturing

Creating a professional tech pack used to require either expensive technical design expertise or hours of painstaking manual work in Excel. Today, AI tools like Apparo can generate a complete, factory-ready tech pack in under 30 seconds. But understanding the process — even if you use AI — makes you a smarter brand founder.

Here's exactly how to make a tech pack for garment manufacturing, step by step.

Step 1: Gather your garment information

Before you open any tool, have these details ready:

• Garment category (hoodie, t-shirt, jogger, etc.)
• Target gender and fit (men's, women's, unisex, oversize, slim)
• Fabric description (cotton percentage, weight in GSM if known)
• Key design details (pockets, zippers, ribbing, drawcords)
• Size range (XS–2XL, S–L, etc.)
• Target market (US, EU, UK sizing standards)

Step 2: Create your document header

Every tech pack needs a professional header with: brand name/logo, document number (e.g. TP-2026-001), revision number (Rev 01), creation date, garment name, category, and production status (SAMPLE or PRODUCTION).

Step 3: Build the measurement table

This is the most technical part. You need to list every measurement point relevant to your garment type, then populate values for each size. For a hoodie, that's typically 12–15 measurement points. Use standard industry increments between sizes (usually 4cm grade on chest, 2cm on sleeve).

Step 4: Write the fabric & BOM

List your shell fabric with full composition (e.g. "80% Cotton, 20% Polyester, 400gsm, French Terry"), then every single trim item. Don't forget the things brands commonly miss: thread colour, drawcord aglet spec, care label placement.

Step 5: Specify construction details

Your factory sample room needs to know: what stitch to use on every seam, how many stitches per inch, seam allowance, hem construction. For an overlock seam: "504 overlock, 12–14 SPI, 1.5cm seam allowance, press flat."

Step 6: The faster way

All of the above can be automated with Apparo. Describe your garment in plain language, and our AI — trained on thousands of real factory specifications — generates every field, measurement, and specification automatically. You then review and edit any specifics before exporting.
