What a tech pack is

A tech pack is the document a factory quotes, samples and produces a garment from: the drawings, the measurements, the materials, the colours, the labels and the construction, in one file with one version.

Updated 30 October 2026

What a factory uses it for

A factory reads the pack three times. To quote, it costs the materials and estimates the sewing time from the flats, the bill of materials and the construction. To sample, the pattern maker cuts from the points of measure. In production, quality control checks pieces against the same measurements and their tolerances, and the packing team follows the label and packing pages.

Whatever the pack leaves out, the factory fills with its own default. That is the main reason a first sample comes back different from what was meant.

What a complete pack holds, and who reads each part

Each part has its entry in the glossary: the technical flat, the points of measure, the bill of materials, colourways, placement, stitches per inch and open items.

What makes a pack usable

  • One version. Every page shows the same style number and date, so an old PDF is never sent by mistake.
  • Codes that match. The code on a dimension line is the code in the points of measure table, and a lettered material on the flat is that line of the bill of materials.
  • Units stated once: inches to the nearest 1/8 or millimetres, and whether a width is measured flat.
  • A tolerance on every point. Without one, any difference is an argument.
  • Gaps named. A question the pack cannot answer yet is listed as an open item, not left blank.

When it is written and updated

The first version goes out with the request for a proto sample. After each fit, the comments go back into the pack as changed measurements or details, and the version date moves. By the pre-production sample, the pack describes the garment exactly as bulk will be made.

How the Texhub Studio builds one

In the Studio, a pack starts from a catalogue garment, or from photos of a garment that the assistant draws. The flat, the points of measure, the bill of materials, the colourways and the labels live in one document, so a change to one shows in the others. The pack exports as a vector PDF for the factory, and the flats as SVG for Illustrator. Making a tech pack with AI goes through it step by step.

See a page of a complete pack for each core garment in the tech pack examples, and send a finished pack to factories from Sourcing.
