When visiting a hair salon or a barber, you may be asked to choose how long or short you want your hair by picking a number. These numbered haircuts correspond to blade attachments for the hair clippers. Knowing what the numbers mean is an important step in making sure you get the haircut you desire.
A haircut with a #1 attachment will cut the hair to an eighth of an inch.
Using a #2 blade, the hair will be cut to a quarter of an inch in length.
The #3 clipper attachment cuts hair to three-eighths of an inch long.
A haircut using a #4 blade will cut hair to half an inch long.
A #7 haircut leaves the hair at seven-eighths of an inch long.
The #8 blade attachment gives the longest haircut, cutting the hair to one inch in length.
