Best BJJ Gi Size Chart

Gi Size Chart

    If you’re anything like me trying to find out my correct gi size was a harder task than rolling with a high school wrestler hopped up on pre-work out – especially when buying my first gi.

Between me and my three brothers we must own close to two dozen gi’s. Most of which just stay hung in the closet stuffed behind the winter coats – due too improper sizing, fit, or just plain preference.

After much trial and error, I have created the most simple and accurate gi size chart that I have used without issue when purchasing my last several gi’s.

     Be aware that the manufacturer is king when it comes to sizing.

Its likely they don’t offer certain sizes or that they offer other sizes not listed on this chart.

This chart is to give you a general idea of gi sizes when it comes to the most common sizes, and the ones that are usually available by most gi producers.

Furthermore, its also possible that gi’s from one manufacturers are slightly larger or smaller than the same size from a different one.

Gi Sizes and Terms Explained

    In the above chart you may see some terms or abbreviations which are not very common among other articles of clothing. You’ll see terms such as “A2L” or “A3S” and may be wondering what exactly they mean.

Below is a breakdown defining those terms and other common abbreviations you might see when buying a gi.

How to choose the correct gi size

     When considering how to choose the correct gi size, some of it comes down to personal preference, but there are some general guidelines to determine if a gi fits correctly in terms of length:

Other Gi Size Considerations

It’s important to always check with the manufacturer since again their sizing may differ others.

Reviews are often helpful as well as they often mention if the gi size purchase was true to size.

Additionally, consider the washing recommendations by manufacturers as well. Even though some gi’s will say they are “pre-shrunk” you can still expect them to shrink a bit when drying especially when using high heat.

It is my strong recommendation to always wash your gi in cold water* immediately when getting in from class and then hanging it to dry. Not only will drying on high heat possibly shrink your gi, it may also damage the seams and any patches etc. Opting to hang dry just simply makes your gi last longer.

While its not recommended, you can shrink your gi depending on material by washing it then drying it on high heat.

It is best to check with the manufacturer on washing instructions since they may recommend drying on low heat or avoid machine drying all together.
