Haircut number and sizes play a great role when it comes to perfect hairstyle. Desired hair length isn’t possible without a right hair clipper size. The knowledge of right clipper size is necessary irrespective of whether you are a professional barber or want to get your haircut on your own. Basically, haircut number represents the size of guard clipper size which is mounted on the clipper. The size of clipper means the size of hair left after cutting. The value of a number is directly proportional to the size of the hair, i.e. the greater the number will be the longer the hair left after use. Different brands offer their haircut number kits, and every haircut clipper size varies 1/8 of an inch. Number 3 haircut means 3/8 inches hair on the scalp while haircut number 4 will give you ½ inch length.
Different Haircut Numbers & Hair Clipper Guard Sizes
The selection of hair cut number and clipper guard sizes depend on haircut style that a person chooses. But here are the haircut number and the length you get from it. Before sharing the haircut numbers and respective lengths, we will give a brief detail of hair terminologies used by barbers so you may understand the exact length required for your favorite haircut.
Taper: Taper is a common term used by barbers. It means the length of your hair will gradually decrease from top to bottom. No clippers are used in tapering while it doesn’t require a short haircut.
Fade: Fade means the change of length from top to bottom in such a way that seems to fade out. Some people get confused between taper and fade due to the similarity, but both are different in looks. Guard clippers are used in fading while expert hairdressers can make taper haircut with scissors.
Neckline: Neckline greatly impacts on your overall haircut appearance. There are three main necklines. Usually, barbers offer, i.e. tapered, round, and blocked. In tapered neckline, the natural neckline is followed and gradually shortened the length. You don’t need to get a haircut again and again as it gets mixed with rest of your hair and gives a neat look for the longer time. Blocked neckline is used to give a wider look at your neck and good for those who have thin neck shapes. Short term clean look is a major drawback of this haircut as the growing hair disturbs the overall appearance. Rounded neckline is similar to the blocked neckline, and it gives untidy looks when your hair starts growing again.
Texture: The choice of texture absolutely depends on the kind of your hair. Curly, thick, and thin hair textures differ from each other.
1. Choppy texture gives outstanding results when you want to add volume to your hair. The cutting involves different lengths which are being cut the difference of 45 degree angle and results in well grown and puffy appearance.
2. Razored texture is for those who have curly hair, and they want to manage the bulky look of the hair. It gives the slightly edgy appearance and helps you to lay flatter on the top.
3. Layered texture involves different hair lengths to give an appearance of depth and richness. The short hair resides on the top of the longer hair and adds volume.
4. The thin texture is the solution of immensely thick hair. Barbers cut down some of your hair strands from different sides without giving it an obnoxious
Sideburns: Sideburns are another important factor in haircut which one shouldn’t ignore if he wants to get a perfect haircut. Top of the ear, bottom of the ear, and mid ear are three self-explanatory types of sideburns. Different clipper sizes and trimmers are used to make your sideburns thin or noticeable.
Buzz Cut: Buzz haircut is categorized in short haircuts and known as a military haircut. Extremely short top hair, side fades, and thin sideburns are used in a buzz cut. Smaller guard clipper sizes are used for this haircut and it better to tell the guard clipper number to your barber, so he gets to know the exact type of buzz cut you want to get.
Crew Cut: Crew cut is another most demanded haircut that can be achieved by giving even haircut at the top of the head and clipper tapers are used at the sides and back of the head to make fades.
Ivy League: Harvard, Brown, and Princeton Clip are other names of Ivy League haircut. Most of the barbers use scissors instead of clippers to maintain the top shape at the top head.
Businessman Haircut: Peaked or taper haircut are the alternative names of businessman haircut. The top of head hair length of this haircut is about 2 inches. Guard clippers are used for sideburns, but scissors are used to maintain the top head length.

Fade Cut: Simple side and back tapering is used in side cut that is done with the help of clippers. The selection of low and high fades depends on the person.

Scissors are used at the top of hair while smaller numbers of guard clippers are used at both sides and back of the head to make a variation of fades.
High and Tight: This haircut requires the shortest size of a hair on both sides and back. The haircut is a variation of different fades which can be seen at both sides and neckline. An inch or half an inch of length is perfect for top hair. Barbers use scissors or clipper #8 to maintain this hair length. Little maintenance is distinguishing feature of this haircut that makes it popular among young boys and middle-aged men.

You may sweep and slicked the top hair while the fade sides give neat and clean looks. Undercut gained popularity after the appearance of James Dean in different movies.
Square Flare Shape: Square flare shape is similar to undercut, but straight line across the hairline makes it different. It’s one of the neatest haircuts due to the sleek sideburns and clean neckline. However, you require more maintenance as grown hair can ruin the overall shape of your haircut.
Men’s Asymmetrical: Due to the uneven sizes of both sides, this haircut is known as a sophisticated and tricky haircut that needs more expertise and skills on the use of guard clippers.
