Router bit sizes are typically indicated by two measurements: the shank diameter (the part that fits into the router) and the cutting diameter (the width of the cut the bit makes). For example, a 1/4" shank with a 1/2" cutting diameter means the bit fits a 1/4" router collet and cuts a 1/2" wide groove. Always check both measurements to ensure compatibility with your router and your project needs.
