What a Tech Pack Actually Needs to Include

A missing line in a tech pack doesn't get caught in review. It gets caught in a finished garment that's already been produced wrong.

"A tech pack isn't a reference document. It's the only document — everything a factory builds comes from what's written in it, not what was discussed on a call."

The Document a Factory Actually Builds From

A complete tech pack typically includes flat sketches from multiple angles, a graded specification sheet with measurements for every size, fabric and trim details down to specific suppliers and codes, construction and stitch notes, artwork placement and color callouts, and a bill of materials — every piece of information a factory needs without having to guess or ask (Techpacker, The Ultimate Guide to Tech Packs in Fashion).

Why "We'll Explain It on the Call" Doesn't Work

A factory, especially one working across a language and time-zone gap, builds from what's documented, not from what was said out loud once and never written down — verbal clarification during a call routinely fails to make it into the actual production run, which is exactly why a rigorous, complete tech pack matters more than a well-organized meeting (MakersRow, Create a Perfect Apparel Tech Pack: The Ultimate Guide).

Where Incomplete Tech Packs Actually Cost Money

Every gap in a tech pack becomes a question the factory has to ask, a guess it makes on its own, or a sample that comes back wrong — and any of those three outcomes adds real time to a schedule that a thorough document could have avoided entirely.
