EXERCISE 31: Measurement checking as per
specification sheet
Objectives
At the end of this exercise you shall be able to
• analyse a specification sheet
• check the measurement of a garment as per specification sheet.
Specification Sheet
A garment specification sheet or spec sheet is a technical document that contains the construction details of a
product, a technical diagram/sketch of the garment and the measurements of a product. The industry norm is a
tolerance of 2cm, i.e. 2cm smaller or bigger than the spec.
Tolerance
There can be hundreds of factors that can cause variation in garment measurement. Sewing and garment
construction, small error in cutting and so on. So, technical designer should consider those variations in the spec
sheet. It is important to keep some tolerance to cover the errors that may cause during the processing. To give
you an example when giving body measurement chest, waist or bottom should have +/- 1/2″. While small parts of
the garment should have relatively smaller tolerance. It is up to the tech pack designer to give tolerance that can
cover a variation during production.
Measuring garment as per size specs is a critical aspect in the quality control. Quality garment exporters keep
QCs who can check the fits. During bulk production it is impossible to have all the garments identical. So in a
garment specs designers set a tolerance for each point of measurement. This allows a small margin for error
which is acceptable during bulk production. When we prepare the spec sheet it is important that we keep certain
acceptable margin. We call it tolerance and this is given in certain garment spec sheets. Technical designer
should keep in mind the tolerance needed in when creating spec-sheet. Tolerance is often expressed as (+ / -) in
the spec sheet with acceptable amount.
