Garments Calculators

Getting garment details right is what separates a homemade look from a professional finish. These garment calculators help you work out precise measurements for closures, zips and construction details. Whether you are inserting an invisible zip in a dress back or fitting an open-ended zip to a jacket, accurate sizing saves time, money and frustration.

Standard zip sizes do not always match your garment measurements exactly, so knowing the nearest available size and the right insertion method makes all the difference. These tools take the guesswork out of garment construction planning.
