How Long Does a Tech Pack Take to Make? (Manual vs AI in 2026)
Short answer: a new tech pack takes 4 to 8 hours to make manually. A revision takes 1 to 3 hours. With AI generation, the first draft takes about 3 minutes, and most teams spend 20 to 60 minutes editing and reviewing it before it's factory-ready.
That's the number you came for. The rest of this post is the honest breakdown, including the parts AI doesn't speed up.
Where the manual hours actually go
A tech pack made by hand in Excel or Illustrator breaks down roughly like this:
- Flat sketch: 1 to 2 hours, more if you're drawing front and back from scratch
- POMs and size chart with grading: 1 to 2 hours
- BOM: 30 minutes to 1 hour, more for artwork-heavy styles
- Artwork pages and placement guides: 1 to 2 hours for graphic-heavy garments
- Construction details, labels, formatting, proofreading: the last hour nobody budgets for
That's for one pack. Variations (new colorway, adjusted fit) are faster, 1 to 3 hours, but they multiply. A 20-style collection with 3 colorways each is not 20 tech packs of work. It's closer to 60.
What AI changes
An AI tech pack generator collapses the building phase. You upload a design image, and the system generates the flat sketch, POMs, full graded size chart, BOM, and artwork pages in about 3 minutes. Here's the step-by-step if you want to see the flow: How to Auto-Generate Garment Specs from a Design Image.
Your job shifts from building to editing. Checking the POMs against your fit standards, adjusting BOM items, fixing the things AI got wrong. For most styles that's 20 to 60 minutes of focused review.
A real stress test from our own platform: we ran a jacket with 37 unique patches through the generator. Every patch was extracted, color coded, sized, and positioned. 37 of 37, with one partial-view patch needing manual cleanup. Full tech pack in 7 minutes, with roughly 80% of the work auto-completed. A year earlier that garment would have been a full day of work.
So the honest comparison for a typical style:
- Manual: 4 to 8 hours
- AI generated plus human review: 25 minutes to about an hour
That's not 100x faster. It's 5 to 10x, because the human review is real work and you shouldn't skip it. But 5 to 10x across a 60-pack season is the difference between a team that's drowning and a team that's ahead.
What AI doesn't speed up
Worth being direct about, because anyone promising you a zero-touch tech pack is selling you a sample disaster.
AI doesn't speed up your design decisions. If the design isn't final, no tool makes the tech pack faster, because you'll be remaking it. (This is our golden rule: AI Tech Packs is a production tool, not a design tool.)
It doesn't speed up fittings. Your 1st proto still needs to go on a body, and the measurement changes that come out of that session are judgment calls, not generation tasks.
And it doesn't fully remove factory back-and-forth, though live share links shrink it by killing the stale-version problem.
How to actually capture the time savings
Speed from AI compounds when the rest of your workflow is set up for it: defaults saved, repeat specs templated, the season batched instead of trickled. We wrote the full playbook here: How to Make a Tech Pack Faster: 7 Workflow Tips.
