Hair Clipper Guard Sizes
Clipper guards are also known as clipper guide combs come in a variety of sizes and are designed to ensure the clipper goes uniformly around the head scalp to produce an even cut.

The clipper guard also serve as a good tool to help styling the hair you are cutting

To get a good, even result, particularly when you are cutting very close to your head, it is important to use a hair clipper guard with your hair clippers.

Most home clippers tend to come with hair clipper guards to help the user control the size of hair that is left behind after the haircut.

Once you have learned the basic art of cutting hair with the clippers, you can then go on to create cuts of different lengths using the various sizes.


Hair Clipper Guard Sizes

Human scalp hair have been found to grow on average about one eighth inch per week or one half inch per month.

Most hair clipper guards are therefore numbered in eighths of an inch.

The label number on the guard represents the number of week’s hair growth that will be left on the scalp when a clipper with a certain numbered guard is guided over the head with the guard in contact with the scalp.

The standard principle is that the higher the label number, the more hair is left on the head after the cut

For example, a #1 hair guard will be expected to leave 1/8″ (3mm), which is, one week’s growth of hair on the scalp if used;

A #2 hair guard will be expected to leave 2/8″ (6.3mm), which is, two week’s hair growth, on the scalp;

A #3 guard is expected to leave 3/8″ (9mm), which is, three week’s hair growth on the scalp; and so on


Although the lengths are standardized,  there are some subtle differences between the numbering system used by different hair clipper guard manufacturers.

The 3 major brands are Oster. Wahl and Andis. have created a list below of some of the most common clipper guard and blade sizes.
