How to Understand the Numbers

The numbers refer to the length of the guard on the clippers that the hairdresser will use to cut your hair. The guard is the plastic attachment that fits over the clippers and determines how close to the scalp the hair will be cut. The higher the number, the longer the hair will be.

The most common numbers used are:

  • Number 1 - ⅛ inch or 3mm
  • Number 2 - ¼ inch or 6mm
  • Number 3 - ⅜ inch or 9.5mm
  • Number 4 - ½ inch or 12.7mm
  • Number 5 - ⅝ inch or 15.8mm
  • Number 6 - ¾ inch or 19mm
  • Number 7 - ⅞ inch or 22mm
  • Number 8 - 1 inch or 25mm

It's important to note that these measurements may vary slightly depending on the brand of clippers or the hairdresser's preferences. It's always best to confirm the length with your hairdresser before they start cutting.

Step by Step Guide

Here's a step by step guide on how to communicate the desired length of your hair to your hairdresser:

  1. Decide on the length you want
  2. Find out what number corresponds to that length
  3. Tell your hairdresser the number you want
  4. Confirm the length with your hairdresser before they start cutting
  5. Relax and let your hairdresser work their magic

It's that simple!
