New Detailed Uniform Sizing Charts

Buying clothes online can be hard. You can't try anything on and so you don't know what will fit. What if the material is too thick or too thin? We strive to make shopping with KarateMart as painless as possible, which is why we have now made new sizing charts that are a little more detailed than what you see on our product pages.
Lightweight Student Uniform
Lightweight uniforms are often the first uniforms that beginning martial arts students wear. While they typically come in black or white, you'll want to check with your sensei to make sure that there aren't any color constraints for you. Sometimes, new students are only allowed to wear white.
The sizing chart below is specific to our exclusive Lightweight Student Uniform, which has hidden side pockets on the pants and is a little more durable than most lightweight uniforms.
- The A Column measures the length of the jacket arms from one wrist to the other when your arms are up straight like the letter T.
- The B Column measures the height of the jacket up to the shoulders.
- The C Column measures the width of the jacket's chest. If you measure your chest the way seamstresses do, just double this number.
- The X Columns measure the elastic waist sizes when they are relaxed (X1) and expanded (X2).
- The Y Column measures the rise, between the groin and the waist
- The Z Column measures the inseam.
Middleweight Student Uniform
Once you've trained enough, you might appreciate a heavier uniform, which can take a little more rough sparring and will last you longer. Newer students typically have more trouble with heavier uniforms, which are a little stiffer and harder to train in if you don't know what you're doing. At 8 ounces per square meter, the Middleweight Karategi is a step up in quality without sacrificing too much in maneuverability.
Plus, you get two additional colors: red and blue.
- The A Column measures the length of the jacket arms from one wrist to the other when your arms are up straight like the letter T.
- The B Column measures the height of the jacket up to the shoulders.
- The C Column measures the width of the jacket's chest. If you measure your chest the way seamstresses do, just double this number.
- The X Columns measure the elastic waist sizes when they are relaxed (X1) and expanded (X2).
- The Y Column measures the rise, between the groin and the waist
- The Z Column measures the inseam.
Super Middleweight Student Uniform
The Super Middleweight Karategi is the next step up after middleweight in quality and thickness. This uniform can absorb more sweat, but takes longer to dry and iron.
A nice thing about super middleweight gis is that you can buy the Super Middleweight Top and Super Middleweight Pants as separate pieces, which is helpful if your pants size is different from your jacket size. Sometimes your top says "size five" but your pants scream "size six." Just remember when mixing and matching like this that the belt that comes with the uniform isn't automatically included.
Please take note that the measurements for the Middleweight, Super Middleweight, and Heavyweight are identical except for the sizes available. The measurements for the Super Heavyweight are also the same except that the waist on the Super Heavyweight Karate Gi is not elastic. The Super Middleweight has the largest sizes available while the Heavyweight and Super Heavyweight are only available up to size 8. If you are moving beyond lightweight uniforms and can only look at one chart, the size chart for the Super Middleweight has all the information you need.
- The A Column measures the length of the jacket arms from one wrist to the other when your arms are up straight like the letter T.
- The B Column measures the height of the jacket up to the shoulders.
- The C Column measures the width of the jacket's chest. If you measure your chest the way seamstresses do, just double this number.
- The X Columns measure the elastic waist sizes when they are relaxed (X1) and expanded (X2).
- The Y Column measures the rise, between the groin and the waist
- The Z Column measures the inseam.
Heavyweight Student Uniform
The nice thing about the Heavyweight Karate Uniforms, which weigh 12 ounces for every square meter of fabric, is their responsiveness. These uniforms are heavy enough to produces a loud snap whenever techniques are performed at high speed followed by sudden stops, which makes them great for tournaments and demonstrations. While the other uniforms come with a white rank belt, the Heavyweights do not. The assumption is that, if you are proficient enough in the martial arts to comfortably use a Heavyweight Karategi, you have probably gotten a higher rank by this point.
As is the case with the Super Middleweight Karate Uniforms, you can get the Heavyweight Top and Heavyweight Pants as separate pieces. This is helpful when your top and bottom halves fit better at different sizes and when you lose one half of your uniform in a karate-themed adventure.
- The A Column measures the length of the jacket arms from one wrist to the other when your arms are up straight like the letter T.
- The B Column measures the height of the jacket up to the shoulders.
- The C Column measures the width of the jacket's chest. If you measure your chest the way seamstresses do, just double this number.
- The X Columns measure the elastic waist sizes when they are relaxed (X1) and expanded (X2).
- The Y Column measures the rise, between the groin and the waist
- The Z Column measures the inseam.
Super Heavyweight Student Uniform
The Super Heavyweight Student Uniforms are the thickest karate gis, measuring 14 ounces per square meter of fabric. The super heavyweights are no joke and can also produce the audible snap like the heavyweights. While the other uniforms come with a white rank belt, the Heavyweights and Super Heavyweights do not. If you are skilled enough to comfortably use a Heavyweight Karategi, you probably don't need a white belt.
- The A Column measures the length of the jacket arms from one wrist to the other when your arms are up straight like the letter T.
- The B Column measures the height of the jacket up to the shoulders.
- The C Column measures the width of the jacket's chest. If you measure your chest the way seamstresses do, just double this number.
- The X Column measures the waist size
- The Y Column measures the rise, between the groin and the waist
- The Z Column measures the inseam.
