If you’re serious about producing clothing that matches your vision, a tech pack is one of the most important documents you’ll create.
What a Tech Pack Is
A tech pack, short for technical package, is the core instruction set a clothing factory uses to make your design. It translates your creative idea into precise, buildable instructions that a manufacturer can follow without guesswork.
What It Includes
Typical elements of a tech pack:
• Technical sketches: Flat drawings showing construction from multiple angles
• Measurements: Specs for size grading and tolerances
• Bill of Materials (BOM): Every material, trim, and label item needed
• Construction details: Stitches, seams, finishes
• Colorways and Pantone codes: Ensures consistent colours throughout production
Why It Matters
Clarity for the Manufacturer
Without clear specs, manufacturers must guess how you want a garment built. That leads to errors, more sample rounds, and increased cost.
Fewer Sampling Rounds
A thorough tech pack reduces the number of revisions needed to get a sample right, saving both time and money.
Better Pricing Accuracy
Manufacturers base costs on exact specs. The clearer your tech pack, the more accurate your pricing from the start.
Consistent Results
When your spec is well documented, the final product will match your vision much more closely.
