How to write a tech pack a factory can actually cost

A tech pack tells the factory exactly what to make. It needs a flat sketch, a measurement chart with tolerances, the fabric and trims (bill of materials), colours, artwork and label placement, and packing instructions. Missing measurements and vague fabric descriptions are the most common reasons a sample comes back wrong.

What goes in it

  • Front and back flat sketch
  • Measurement chart for every size, with tolerances
  • Bill of materials: fabric, weight, composition, trims
  • Colours with Pantone or lab-dip references
  • Artwork, logo size and placement
  • Label copy: brand, size, composition, care, origin
  • Packing: folding, polybag, carton

Common mistakes

  • No tolerances on measurements
  • Fabric described as 'soft cotton' instead of weight and composition
  • No placement measurements for logos
  • Care and origin text missing from the label

Questions

Can I use a template?

Yes — the content matters more than the format.

Does the factory need the tech pack before a quote?

For an accurate quote, yes. Without it, you get a range.
