Here's a quick reference for the different haircut lengths. Number 1: One-eighth of an inch. Number 2: One-quarter of an inch. Number 3: Three-eighths of an inch. Number 4: Half an inch.

Number 3. This clipper size cuts to a length of ⅜ inches to about 7/16 inches if it's open. If you're opting for a fade, it might be best to ask your barber to start with a 3 so then they can move down to a 2 and lower as they fade it out. It also helps you keep more of your length.

Basically, the larger the number, the longer your haircut will be. If you walk into a barbershop and ask for a number 6, you will receive a six guard and walk out with 3/4 of an inch of hair left. On the flipside, if you ask for a 1, you will receive a nearly-shaved head.
