A garment specification sheet (mostly called as spec sheet) is a technical document that comprises the construction details of the product, a technical sketch of the garment, and the measurements of all the parts mentioned in the spec sheet. In this article, we will show you how to make a spec sheet of an apparel item.

The spec sheet is generally given/issued by the buyer to the product development merchandisers in order to create a sample. The spec sheet is normally received as in soft copy (PDF file) from the buyer.

The measurements play a very crucial role in deciding the fit of the garment. The garment specs are referred at all stages of sample development. Pattern makers use measurements as a guide for the general size and fit of a particular finished garment. People follow different measurement standards in different parts of the world. So, it’s essential to know the various points of measure, some of the POM’s are as follows:
  1. Body Length: length of the garment from HPS (high point shoulder) to the bottom sweep.
  2. Across Chest: Measured 1” below armhole horizontally from edge to edge.
  3. Waist: Measured horizontally from edge to edge to a specific distance below HPS.
  4. Bottom Hem: Measured side seam to seam
  5. Shoulder seam: Measured from HPS along the seam or along the natural fold line to the outer shoulder edge.
  6. Across Front: From specified point below HPS, measure straight across edge to edge of armhole.
  7. Across Back: From specified point below HPS, measure straight across edge to edge of armhole.
  8. Bicep: Measured 1” below armhole, measured straight across edge to edge parallel to the sleeve opening.
