Sizing Guides

Karate / Judo / Jiu-jitsu / Aikido Uniform Sizing Guide

When choosing your uniform size consider the following: HeightBuild and Shrinkage*

For example, if you are 180cm tall and an average build you should fit a 5/180 uniform. If you are a thin/lean build then you should consider a 4/170 uniform. If you are a solid/stocky build then you should consider a 6/190 uniform (it’s OK if the ties do not pull shut completely). Please note that in some cases you may need to alter the length of the sleeve and pant.

Use the chart below to help make your decision. If you have any questions don't hesitate to contact us.

*How much should I allow for shrinkage? Generally, polycotton may shrink up to 3-5%, and cotton/canvas may shrink up to 5-10%. These shrinkage rates are directly linked to how you care for your uniform. See Uniform Care for more information.

TIP: If you're using a small mobile device swipe across the table to see all sizes.

Martial Arts Belt Sizing

If you wear a size 5/180cm uniform then you can reasonably expect to wear a size 5 belt.  However, given the wide variation in people’s waist sizes, use the following formula to more accurately work out the correct belt size for you.

Decide how low you want the belt to hang down, e.g. 3cm longer than your jacket length. Now measure your waistline with your uniform on, and calculate:
(Waistline cm x 2) + (hang length cm x 2) + 30cm for knot = belt length

For example, with a 98cm waist and a jacket that is 29cm long, you would calculate:
(98cm x 2) + (32cm x 2) + 30cm = 290cm = size 6 belt

Note for single-wrap styles, do not multiply the waistline measurement by 2. If the calculation does not quite work out to an exact belt size, go a little longer – belts can shrink a little over time, or can be shortened.

Use the chart below to help make your decision. If you have any questions don't hesitate to contact us.

Belt-Size 0/180 1/200 2/220 3/240 4/260 5/280 6/300 7/320

HOW TO PROPERLY WEAR YOUR MARTIAL ARTS BELT

The belt sits on your hips, below the waistband of your pants. The belt goes around your waist and hangs down to the front, with both sides being an even length. Ask your Instructor what method of tying your belt is appropriate for you. There are many tutorials available on the web.
