Bill of materials (example layout)

The same columns most tech pack templates use. Add supplier codes and color references when you have them.

Bracketed cells are what you or your factory still fill in.

Points of measure (example layout)

The draft picks points that fit the garment type. Values stay blank until you give them, and the tolerance column is for you to agree with the factory.

Code	Point of measure	Base size M	Tolerance +/-
A	Body length from high point shoulder	[cm]	[cm]
B	Chest width, 1 inch below armhole	[cm]	[cm]
C	Hem width	[cm]	[cm]

A tech pack tells a factory exactly how to make your garment. Writing the first one is slow, and a blank template does not tell you which points to measure or which trims to list. This free tech pack generator turns a short garment description into a structured draft with a bill of materials, a points-of-measure table and construction notes, ready for you to complete and check with your factory.

What goes in a tech pack

Most tech packs have the same parts: a cover page with the style name, season and size range; flat sketches of the front and back; a bill of materials listing every fabric, thread, trim and label; a points-of-measure table with a tolerance for each measurement; construction details such as seams, stitches and finishes; and labelling and packing instructions.

A tech pack template filled in for your garment

Instead of a blank tech pack template, you get one written for your style. A hoodie gets rib cuffs, a kangaroo pocket and drawcord points; a shirt gets collar, placket and button points. Paste the tables into a spreadsheet and add your values.

What you still need to add

Measurements and grading for every size, flat sketches, fabric swatches or supplier codes, artwork placement files and approved colour standards. The draft marks what is missing with placeholders and lists the open questions, so nothing is left to the factory to guess.

Who it is for

Small clothing brands, print-on-demand sellers moving to cut-and-sew, and designers who are writing their first tech pack and want the structure right before they spend on samples.

FAQ

Tech Pack Generator: questions sellers ask

What is a tech pack?

A tech pack is the instruction file a factory uses to make a garment. It usually holds the style details, flat sketches of the front and back, a bill of materials (fabric, thread, trims, labels), a points-of-measure table with tolerances for each size, construction notes and packing details. A complete one means fewer questions and fewer wrong samples.

What does this tech pack generator make?

A text draft in six sections: style info, flat sketch notes in words, a bill of materials table, a points-of-measure table, construction notes and questions for the factory. Paste it into a spreadsheet or your tech pack template, add your sketches and measurements, and check it with your pattern maker or factory.

Will it fill in my measurements?

Only the ones you give. Measurements are specific to your pattern and size chart, so the tool lists the right points of measure for your garment and leaves the values as [cm] placeholders. It may suggest common tolerances or stitch types, marked [confirm], for you to check.

Does it draw the flat sketches?

No. It describes the front and back views and the design details in words, so you or a designer can draw the flats in Illustrator or a CAD tool. To show the garment itself, you can make a flat lay or mockup image with our image tools.

Can I send the draft straight to a factory?

Not as it is. Treat it as a structured starting point. Fill in the measurements, check the materials and construction with your pattern maker, and add sketches and size grading before you ask for a sample. Factories work from what the tech pack says, so every gap becomes a question or a mistake.

Is it a tech pack template too?

Yes. The sections and table columns follow the layout most tech pack templates use, so you can use the result as a filled-in template for your style. The example on this page shows the format for a simple T-shirt.

What should I type to get a good draft?

The garment type, fit, fabric and weight, key details (pockets, closures, trims), the base size, the size range and the colours, in under 200 characters. The more real facts you give, the fewer placeholders you get.

Can I edit the copy?

Yes. Copy it out and edit it anywhere, or change your input and generate again for a new version.

Which languages are supported?

English, Spanish, French, German, Italian, Portuguese, Dutch and Japanese. Pick one in the Language option.
