girls practicing karate in their gi

Karate is a popular form of martial arts loved by many people across the world. Unlike what many people think, karate is not about fighting it is about discipline and self-defense.

It teaches you how to maintain coolness when everyone around you is losing theirs. Karate is about how you can defend yourself only when necessary.

This martial art is also great for your body as it involves exercising, movement and stretching, which can burn up to 500 calories in an hour.

Starting karate is easy because all you need is to find a good school and get a uniform, called the karate GI.

What you should know before buying a karate GI

Karate uniforms come in a wide range of styles, weights, and cuts. This means if you are planning on buying one, you need to consider a number of things.

The ideal type

Karate uniforms are categorized into two – kata gi and kumite gi.

Kata gi is typically used for a choreographed form of karate or Kata. It is heavy as well as more well made.

Kumite gi on the other hand is usually used for training and sparring. It is lighter compared to Kata gi, and much more flexible.

Type of karate gi for a tournament

Not every karate gi is suitable for international tournaments. Kumite gi is mostly used but must be approved by the World Karate Federation (WKF), a body that governs Karate sport.

International competitors are however immune to this regulation and can buy any karate gi they need.

If you are just doing local tournaments, then a normal gi is just fine. You do not have to worry about WKF approval.


In terms of weight, there are three major categories:

Lightweight: Normally used by beginners and kids and weighs between 140 and 200 grams (5oz – 7oz)

Middleweight: Used by most karate students notwithstanding of their ranks and weighs from 255 to 368 grams (9oz – 13oz)

Heavyweight: Used almost exclusively by highly ranked masters in demonstrations in front of crowds. It doesn’t have a concrete purpose and cannot be worn in tournaments. It weighs between 368 and 481 grams (13oz – 17oz).

In addition to the categories listed above, you should also consider the climate in which you will be training.

Wearing a heavy gi in 90 degree temperatures would not be good.


The number one factor you should consider in a karate gi is comfort. Remember you will be moving, kicking, and punching while wearing the uniform, so it should be comfortable.


Karate gi pants are made to be durable and long lasting. The most popular fabric is 100% cotton, but you can also choose GIs made from a mix of materials. Any material besides cotton may not last long.

Jacket length

The jacket length is determined by personal style and preference. Some people like it short while others prefer long.

Sometimes the length of the karate GI jacket may also be determined by the amount of fabric left below the belt. The ideal length, however, should not get in your way you throwing a kick or a punch.


Does the color really matter?

Yes, every karate class has its own uniform color. So before buying, be sure to check with your master or gym and find out what they allow. Some schools allow all colors, in which case you can customize the uniform to suit your style.


The last factor to consider before buying a karate GI is the price. You need to find the right balance between price and the quality of the uniform to get the value for your money.

Does karate gi shrink?

Karate gi, just like most other clothes, may shrink unless you get a high-quality product or a gi that is pre-shrunk.

You may want to buy a larger size and hem the pants and sleeves up. Once your child grows you can undo the hem and lower the length to get the perfect fit.

Cotton fabric tends to shrink up to 9%, particularly in the first couple of washes.

A blend of cotton and polyester will shrink less compared to 100% cotton. For kids, it is recommended to buy a poly-cotton uniform because of its minimum shrinkage, which is suitable for fast-growing kids.

High-quality karate gi uniforms from reputable manufacturers come pre-shrunk so that it does not shrink significantly.
