A tech pack is the instruction document used to turn a clothing idea into a repeatable product. It gives the pattern maker, sample room and production team one agreed source of truth for construction, measurements, materials and branding.
Why a tech pack matters
Without written specifications, two people can interpret the same reference image differently. A good tech pack reduces guesswork, produces more accurate quotations and makes revisions traceable.
| Section | What to include | Why it matters |
|---|---|---|
| Technical drawings | Front, back and detail views | Shows construction clearly |
| Measurements | Points of measure, base size and tolerances | Controls fit and consistency |
| Materials | Composition, GSM, colour and finish | Controls feel, performance and cost |
| Trims | Zips, buttons, drawcords and hardware | Prevents substitutions |
| Artwork | File, dimensions, colour and placement | Ensures correct branding |
| Labels and packing | Neck label, care label, hangtag and bag | Makes the item retail-ready |
Core components
Technical flats
Use clean line drawings rather than lifestyle sketches. Call out pockets, seams, rib panels, fastenings and internal details.
Bill of materials
The bill of materials lists every fabric and component. Include supplier references when fixed materials are essential, but allow an approval process for equivalent alternatives if sourcing flexibility matters.
Measurement specification
Define exactly how each measurement is taken. Include a base size, grading rules and realistic tolerances. Terms such as “regular fit” are not measurable.
Artwork and branding
Provide vector artwork where possible, Pantone or other colour references, finished dimensions and placement measured from fixed garment points.
Tech pack versus reference sample
| Method | Best use | Limitation |
|---|---|---|
| Tech pack | Precise, scalable production | Requires preparation |
| Reference garment | Communicating fit and feel | Does not explain hidden construction |
| Image or sketch | Early concept discussion | Too ambiguous for final production |
Common mistakes
- Missing artwork dimensions or colour codes
- Using inconsistent measurement names
- Changing requirements in messages but not updating the document
- Leaving labels, packaging or testing until the last minute
- Assuming the factory will select the intended fabric automatically
You do not need expensive software to begin. A clear spreadsheet and annotated vector drawings can work. What matters is that the document is complete, version-controlled and approved.

Frequently asked questions about clothing tech packs
What format should a tech pack use?
A PDF is useful for controlled sharing, supported by editable source files and spreadsheets. Use clear version numbers so the factory and brand review the same specification.
Who creates a fashion tech pack?
A technical designer commonly prepares it, but small brands can build one with precise drawings, measurements and material details. A manufacturer may help refine production information.
Does every garment need its own tech pack?
Each distinct style should have its own controlled specification. Related styles can share standard label, packaging or material information where applicable.
Can a manufacturer quote without a tech pack?
A preliminary estimate may be possible, but a reliable quotation requires enough detail about fabric, construction, branding, sizes and quantity.
