5 min


Maybe you have watched some tutorials on how to cut hair or are you going to a barbershop for the first time but are still confused about hair clipper sizes.

It’s important to know what lengths correspond to different hair clipper guard sizes because if you care about how your hair looks (and you absolutely should), then you shouldn’t just let the hairdresser do whatever he wants.

Different brands offer their haircut clipper guard sizes, and each haircut clipper size varies 1/8 inch. Haircut number 3 means 3/8 inch hair on the scalp, while haircut number 4 gives you a length of ½ inch.

To help men visualize haircut numbers, hair clipper guard sizes, and the corresponding hair length, we have detailed a detailed description with photos.

What Are Haircut Numbers and Clipper Guard Sizes?

Haircut Numbers and Clipper Guard SizesLet’s start with the basics if any women plan to help their men trim facial or scalp hair. Haircut numbers refer to the sizes of the clipper guards, and you can find the number etched into the hood itself. Most clipper sets have 8 guards, and each clipper represents the amount of hair left over after use.

The larger the number, the longer the haircut. Often, most brands like Oster and Andis, Wahl clippers guard sizes use 1/8 inch increments.

For example, asking for a “Number 1 Haircut” means that the #1 guard will be attached for a hair length of 1/8 inch. Then a “Number 2 Haircut” is still a concise cut equivalent to 1/4 inch length; a “Number 3 haircut” leaves 3/8 inch of hair; “Number 4 haircut” is a longer, medium-length cut at 1/2 inch; and “Number 5 Haircut” holds 5/8 inch of hair on the scalp. A man can request a haircut with 0, 1, 2, 3, 4, 5, 6, 7, or 8.

Here are the cutting numbers and their respective clipper guard lengths:

  • Number 1 – one-eighth of an inch
  • Number 2 – a quarter inch
  • Number 3 – three-eighths of an inch
  • Number 4 – half an inch
  • Number 5 – five-eighths of an inch
  • Number 6 – three-quarters of an inch
  • Number 7 – seven-eighths of an inch
  • Number 8 – one inch

Number 0 Haircut

Number 0 HaircutThe #0 haircut – or 1/2 for Wahl clippers users – is, in fact, the shortest there is.

In fact, this number has no auxiliary comb; it uses the clippers to deliver clean, even, and immaculate cuts.

With a #0 haircut, the hair is up to 1.5mm or 1/16” long.

It’s the number you ask for if you want any of the following hairstyles:

  • Bald look.
  • The skin fades.
  • Concise buzz cuts.

All # 0 hairstyles often leave the scalp exposed. Also, this hairstyle is quite easy to clean and maintain.

Number 1 Haircut

Number 1 HaircutAlthough a tad longer (1/8 inch, to be exact), ‘Number 1 haircut’ is still very short. Your scalp will be visible – but slightly less than with ‘Number 0 Haircut’. It is usually used for buzz cuts or to taper/fade various haircut numbers.

Number 2 Haircut

Number 2 HaircutThe “Number 2 Haircut” is one of the most popular hair clipper sizes for faded haircuts. Not too short or too long, the #2 gives you a 1/4 inch length, giving you a fuller haircut that doesn’t expose the scalp. A number 2 is a safe bet for men with thinning hair and is probably perfect for thick hair.

Number 3 Haircut

Number 3 Haircut Buzz CutNumber 3 leaves longer hairs on your scalp. While it can be used to create fades or short haircuts like the buzz cut or the crew cut, you can’t really style it too much. A spiky haircut can also be obtained on this hair length. This hairstyle is also easy to maintain.

Number 4 Haircut

Number 4 Haircut Buzz CutA “Number 4 haircut” leaves her 1/2 inch long, making it the average length of clipper guards. With size #4, you can start getting a brush or round cut, similar to a buzz cut but with a fade of the skin on the sides and longer hair on top. The number 4 works well for both thick and thin hair.

Number 5 Haircut

Number 5 HaircutAt 1/2 inch long, ‘Number 4 haircut’ is the medium length – and one of the most popular choices for short hair. Ideal for those with a rounder face, it leaves a good amount of hair while still maintaining a neat hair length. Because a parting at this length is possible, it is very versatile and can be styled in short and longer hairstyles.

Number 6 Haircut

Number 6 Haircut Crew CutThe number 6 haircut is for styles that require 3/4 inch hair length as the #5, a #6 size is usually used for tapered sides. A #6 clipper guard no longer produces a buzz cut but closer to a crew cut at this length and beyond.

Number 7 Haircut

Number 7 HaircutYou will have a lot of hair left if you ask for a ‘number 7 haircut’ (7/8 inch). It is ideal for those who want a light cut and prefers long hair. Remember, you can get more creative with styling when your hair is longer because short styles really won’t leave you much to play with.

Number 8 Haircut

Number 8 HaircutThe number 8 has an overall length of one inch and is the length that is rarely ordered. Number 8 hair clippers are used to trim longer hair and are used for the top of the head. Haircuts with longer hair on top and haircuts on the sides require a number 8 razor. The size of the andis hair clipper in this style is 5.3mm.
