Belt Information

NOTICE: Temporarily, due to supply-chain disruptions, product materials may vary in color and/or texture.


All of our martial arts belts are hand-made in the USA by skilled craftsmen. We use the best materials available such as 100% cotton strapping core, 100% cotton exterior and super-strong polyester thread. All belts have sewn ends and matching thread color. Various belt widths are available: 1.50 inch (narrow), 1.75 inch (standard rank belts), 2.00 inch (rank belts, black belts and master belts), 2.50 inch (large black belts and large master belts), 3.00 inch (XL black and master belts). The thickness of our belts vary for each belt style, especially our different Master Belts. However, rank belts are approximately 3.0mm thick, while "soft" firmness belts are approximately 4.0mm thick, and "stiff" firmness belts are approximately 5.0mm thick. Please note that "stiff" means stiff, and will need some breaking in. Our Grappling Weave belt lines are approximately 5.0mm thick, but are pliable like our "soft" firmness belts. More information on belt firmness.


Kataaro belt sizes are in 5 inch increments, from Size 0000 (75 inch) to Size 24 (210 inch). Our tolerance for length variation is up to 2 inches short and up to 3 inches long. When choosing a size, consider that the wider the belt, the more length is utilized in the knot area. Our Belt Size Calculator can help with making size choices. Also, keep in mind that there may be some other variations (width, thickness, sleeve length, etc.) up to approximately 3/16". Compare Kataaro sizing to some other jujitsu and karate belt brands:

There are a variety of black belts, master belts and rank belts to represent most all martial arts disciplines including karate, taekwondo, judo and jujitsu. If you don't see a style that you need, please let us know.


To add embroidery to any martial arts belt, select YES, add embroidery at the embroidery option. Belt production will begin when the order is placed, but embroidery will not begin until a visual proof is approved. More embroidery info...

Care Instructions

We do not recommend washing your martial arts belt since some shrinkage or discoloration may occur. Additionally, the 100% belts are not considered to be color-fast materials, so color fading may occur under certain washing conditions or with sun exposure. Keep you belt dry and protected from direct sun exposure. See our FAQ page for more care information for your Kataaro belt. For information on how to tie a karate belt, see our belt tying page.
