Tech pack format
Tech pack format: what a factory-ready tech pack includes
Last updated: Published by Cydney Mar
A tech pack format typically includes a cover page, technical sketches, measurements, a bill of materials, colors, construction notes, and label and packaging specifications.
This guide is part of Shelf to Screen, published by Cydney Mar, who creates production-ready tech packs as part of her product development work. It explains each section and the mistakes that cause repeat sampling.
What should a tech pack include?
A tech pack should include everything a factory needs to make your product without asking: sketches, measurements with tolerances, every material and component, colors, construction details, labels and packaging. Confirm the format your supplier expects before finalizing it.

What is a tech pack?
A tech pack is the document that tells a factory exactly how to make your product. In the Shelf to Screen guide by Cydney Mar, it is the bridge between Right Prototypes and Production-Ready: the same document guides sampling and then locks the specification for every unit after.
Cydney Mar puts it this way: a clear, professional tech pack is the difference between a sample that is right the first time and months of expensive back-and-forth.
Standard tech pack sections
Formats differ by category and factory. These sections appear in most consumer product tech packs.
| Section | What it contains | Why the factory needs it |
|---|---|---|
| Cover page | Product name, style number, season, version, date | Keeps everyone on the same version |
| Technical sketches | Front, back and detail drawings | Shows the product without guesswork |
| Measurements | Key dimensions and tolerances | Keeps every unit consistent |
| Bill of materials | Every material and component with supplier details | Sets cost and sourcing |
| Colors | Color references for each part | Prevents color mismatch |
| Construction notes | How parts are joined and finished | Controls quality and durability |
| Labels and packaging | Label content, placement and packaging specs | Readies the product for sale |
How to build a tech pack
- Start from a clear product brief that says what it is and who it is for.
- Draw clean technical sketches with every detail called out.
- List all materials and components in a bill of materials.
- Add measurements and tolerances.
- Write construction, label and packaging notes.
- Confirm with your supplier which format and units they expect, then version every change.
Common tech pack mistakes
- Leaving measurements open to interpretation.
- Changing the design by email without updating the document.
- Missing packaging and labeling details until after samples arrive.
- Skipping the bill of materials, which makes accurate costing impossible.

Common questions
What is a tech pack format?
A tech pack format is the standard structure of a product specification document. It usually includes technical sketches, measurements and tolerances, materials and components, colors, construction notes, labels, packaging and a bill of materials. Formats differ by product category and factory, so confirm what your supplier expects before you finalize it.
Do I need a tech pack before approaching manufacturers?
For most manufactured consumer products, yes. A tech pack tells the factory exactly what to make, so samples come back closer to what you intended. Cydney Mar puts it plainly: a clear, professional tech pack is the difference between a sample that is right the first time and months of expensive back-and-forth.
What if my samples keep coming back wrong?
Samples that keep coming back wrong usually point to an unclear specification or a poor supplier fit. Tighten the tech pack first so the factory knows exactly what to make, then check whether the supplier communicates well. Cydney Mar's pathway vets suppliers for quality, communication and reliability before production.
How do I choose the right supplier?
Choose a supplier on quality, communication and reliability, not price alone. Ask for samples, check how quickly and clearly they answer questions and confirm they can meet your quantities and timeline. The Right Suppliers step of Cydney Mar's pathway focuses on exactly these three tests.
Why do most product ideas never make it to launch?
In Cydney Mar's experience, most founders do not fail because the idea is bad. They take the right steps in the wrong order: they jump into sampling without clarity, choose suppliers based on guesswork, ignore margins until it is too late and try to figure it out as they go. That wastes time and money and stalls progress.
