Tolerances control what variance from the spec measurement is acceptable. Writing proper tolerances is a balance between controlling product quality and having realistic expectations for a production environment. Each POM gets its own tolerance, so how do you get that balance right for each one? These are the factors to consider when writing POM tolerances.
Did you know there is a strategy to writing points of measure? What POMs you choose to include in your spec sheet and how you take those measurements can control the fit and sizes of the garment in different ways. Here’s how to write POMs that bring out the best in your garment and goals.
The fit and sizing of your design all stems from your base size measurements on your spec sheet. So, how do you know what measurements to fill in for your base size? There are several ways you can get these measurements.
Size charts, spec charts, and grade rules are all terms that are thrown around a lot during development and pre-production. While they do sound (and sometimes look a bit) similar, their meanings are all distinct and each has a different use and purpose.
The spec sheet is an important part of the tech pack that shows what the style measures at each POM in all the sizes offered. The chart also shows the tolerance for those measurements – meaning the amount plus or minus that the garment can differ from the spec measurement and still be considered acceptable.
