Questions

What is a grade rule?
The amount a measurement changes from one size to the next, for example 2 cm on half chest between M and L. Each point of measure has its own grade.
Are grades always the same between sizes?
Often, but not always. Some brands use bigger jumps for XL and up. In the Techpackz editor you can set a different grade for each size step.
