The Ultimate Guide to Hair Clipper Sizes for The Best Cut

Many people are showing much interest in creating their hairstyle these days. However, you may not know how to choose the best tools as well as the accessories for your cut. As a result, I am going to help you become familiar with what are the good clipper guards and the bad ones. Moreover, you can identify what hair clipper sizes you should be using and you can get on track to know the numbers. For example, the size number of 1 to 10 along with what measurement they are with the different clipper companies.

What to Notice Before Using the Clipper Guard?

First of all, you need to remember that you should never use a broken guard. The reason is that the guard is going to fall off as soon as you start to cut. Also, you can accidentally create unwanted marking on somebody’s head or even your head. Thus, you should not use any broken guard, especially on the ends.

How to Choose the Best Hair Clipper Sizes

I am sure that more and more people are wondering what the different clipper cutting guide sizes are. Therefore, we are going to attempt to answer this question in a format that is easy to understand.

For example, you can choose a number 4, and there are two numbers on guard. One of them is going to tell you what the millimeter size and the other is the inch size. Some people might be confused between these two figures.

The different types of clippers such as Wahl, Andis, and Oster, have slightly different ways of indicating they are sizes. The differences may not be far from each other, but they do vary. Therefore, you need to check their size charts carefully.

I used to experience making a mistake with a customer related to the guard sizes of different brands. For instance, somebody comes in and says that he/she wants a haircut, and they tell you that their barber usually uses a number 4 guard on the theme.

Nevertheless, a 4-guard on Wahl could be different from how it is on Andis. Each of the clipper company has a slight difference, but in general, he or she is usually the same. So, you always want to make sure that you verify with the person when they say they want number 4 on the sides or in the back.

By doing this, you can know that they mean to have about half an inch left on the sides and the back blended to the top. Number 4 in Andis and Wahl means half an inch. It might be slightly different in some of the Oster where they use more of the millimeter sizing.

At this moment, I am going to make the comparison among these three brands for you. From these tables, you can have an overview of their guide combs as well as their guide sizes.

These slight differences only can make a world of difference. It will be a big problem if your client has their expectation and you are delivering something different from what they expect. So, make sure that you consult with your customers properly before you make any of those guard choices.

Furthermore, you need to know the meaning of the low and the high number. The lower the guard size is, the tighter it is going to the head. When you are using a lower guard number, it would mean leaving less hair on the head.

On the other hand, the higher the number goes, the more hair that will be remaining on the head. Hence, you can know that the key difference lies on the end of the particular cut. I can give you an example like this:

  • Imagine you are doing a number 5 buzz cut. It means that the client wants to have a number 5 guard on top of their clipper. You can put the number 5 guard into the Wahl brand which is about 5/8 of an inch. By using this, you can cut their hair completely all around the top and on the sides.
  • Besides, you will have 5/8 of an inch remaining over the entire head when you are done doing that particular cut. So, keep this tip in mind when you are looking at how the size works. Also, you need to understand when you are going from one size to another size.

Right now, if you want to know more about how to make the buzz cut for men, you can watch this interesting video for more details:

Conclusion

Again, the lower the number is, the shorter the hairline or the haircut is going to be. On the other hand, the higher the number, the more hair that will be remaining at the end. As a result, I wish that all the information in this article will give you a little bit of an indicator of how to determine or understand what the hair clipper sizes are. However, in case you are in need of additional advice and instructions, please feel free to keep in touch with me anytime.
