Clipper Blades and Guards Sizes and Lengths

Cutting Hair by Numbers

By

Among professional products, there are three major clipper brands -- Oster, Andis, and Wahl. Each clipper uses either detachable blades or guide combs and it's quite common for a client to ask a haircut length using a clipper guard number (e.g. "Give me a number two on the sides."). But wait. Each company's clipper blade or guard number isn't always the same length as another company's number. To make things easier, we've created a list of common hair clipper blade and guard sizes.
