Difference Between a Spec Sheet and a Techpack

The specification sheet is commonly referred to as 'Spec Sheet'. The spec sheet is a component of the Technical Package (Techpack), where the Techpack contains absolutely everything required in making the garments - in the sampling stages, in bulk production, in finishing, and in the packing garment. 
In the fashion industry, the spec sheet and techpack are created by the designer or the product developer. 
Spec sheet and Techpack

Though sometimes we use spec sheet and Techpack terms interchangeably, these two terms are different. To differentiate these two terms we can use the following parameters.

To develop a garment sample, you need a full techpack. The spec sheet contains part of tecpack information, mainly the technical sketch of the garment and measurement chart for multiple sizes with grading and measurement tolerances.
With a spec sheet, you can only make the garment patterns and check garment measurements.

Content of a Techpack  
  • A Pattern
  • Testing Details (FPT and GPT requirement)
  • Costing Details
  • Quality requirement 
  • Technical sketch
  • Workmanship and stitching instructions
  • Sample of Fabric, colour combination for trims for different base colours

  • Updated with comments on garment samples submitted to buyers. Mainly size set sample and PP sample comments.
  • Some buyers also include mini marker and fabric consumptions in the apparel techpack 


It is advised to use the correct term when you are communicating with the internal team and with your buyers. Remember, the Techpack can be called a spec sheet, but a spec sheet can't be called a Techpack. The reason, the spec sheet does not have all the information a Techpack should have.
