Haircut Length Chart
Number 1 Haircut
Leaving 1/8 inch of hair, a number 1 haircut is hardly any length. For fade sides and short buzz cuts, a #1 guard is used.
Using a clipper size throughout would show your scalp. So be aware of that.
Number 2 Haircut
This is one of the most popular clipper sizes, used regularly for buzz cuts and faded sides.
The number 2 is also very short but slightly longer than the number 1, being 1/4 of an inch.
But this does not expose the scalp, so it is a safe bet for those who are balding or have thin hair.
Number 3 Haircut
Very popular among all the clipper sizes, number 3 clipper guard has 3/8 inch of a length.
A wide number of barbers use this to cut fades. Since this haircut is short and requires very low maintenance, many men ask for this haircut.
It also works for both thick and thin men’s hairstyles.
Number 4 Haircut
Providing a reasonable length for most of the conservative hairstyles, a number 4 haircut gives you 1/2 inch of hair.
These clippers do not produce a very short buzz, they start bordering on a men’s army cut, crew cut, or brush.
Number 5 Haircut
The number 5 haircut is around 5/8 of an inch, leaving hair long enough to be brushed and styled.
It works well if you do not want to create much contrast, and wish to taper off the sides. For a more classical cut use a #5 clipper and look like a gentleman.
It will help you look more professional if you work in a corporate setting.
Number 6 Haircut
The number #6 works for styles that requires 3/4 inch of hair length, usually being used for tapered sides like the #5.
This gets you something closer to a crew but not a buzz cut.
Number 7 Haircut
Just use a smaller clipper to give a fade hairstyle effect on the sides.
Number 8 Haircut
It will help in giving you a contrast haircut, balancing the #8.
