So, how to choose the right clipper size?

Well, it mostly depends on the look and style you’re going for. Whatever blade or clipper guard you will choose, make sure it corresponds with the style you want to have. If you’re going for haircut buzzed close to the scalp, choose a small size clip with a small number on it. Going for a longer hair? Opt for a big clipper size.

Hair clippers are easy and safe to use for all people, and you just can’t mess up your hairstyle while using them. But if you’re that clumsy, don’t worry; everything is fixable!

You can even experiment with your hair a bit, but whatever you do, you must learn how to use the right hair clipper size for the style you want. As you can see, the sizes range greatly, and thus it’s advisable to know ahead of time what can you expect.

Remember: always go for a clipper size that is slightly longer than you’ll need because you can go shorter anytime you want. You know the saying: measure twice, but cut once.
