The Karate Belt - Length and Width
How long and wide is a Karate belt?
Karate belts are typically 1.5 inches (slightly less than 4
centimeters) wide and about 100 inches (2.56 meters) long. Your
first belt is white and usually comes with the Karate Gi (Karate
Uniform) that you purchased.
An interesting tidbit
is that Karate belts usually have 8 lines of stitching
running lengthwise along the belt. Cheap uniforms may
come with belts that have only 6 lines of stitching. For
some reason, black belts have usually 10 to 12 lines of
stitching which makes the black Karate belt a little bit
White and colored belts are usually made of cotton, whereas
black belts often have a layer of satin over it. After all, the
master has to look slightly more impressive than his students,
and a little bit of satin may just achieve this :-)
If I need to buy a belt, how long should it be?
When you buy a Gi, the length of the supplied belt depends on
the size of the Gi. Later on as you progress through the Karate
belt ranking system, you will need to buy new ones in a variety
of colors. Should your girth be out of the usual range for your
height, you may need to purchase a longer or shorter belt to be
able to tie it correctly. A good rule of thumb to calculate the
length of belt needed is: required belt length equals
approximately 3 times waist circumference.
