Ichiban International size chart

Please stretch out flat before measuring

JacketTrousersHigh waist trousers


All sizes are in centimeters

Assuming you order the correct size the arm sleeve length will fall one third up between the wrist and the elbow. The leg length will be just above the ankle. 

If you like wearing a shorter sleeve and shorter trousers Ichiban recommend you order a part made to measure suit (giving exact dimensions of sleeves and legs). The sizes go according to the person’s height. Every person comes in different shapes and sizes, therefore Ichiban has created the above chart to assist you in choosing the correct size.  Please note that this is only a guideline. Diamensions may vary slightly from one batch to another. Please e-mail Ichiban if you need further assistance.


Belt length


When the belt is made up, lift both ends and ensure that they do not pass your chin.
This is to prevent it from slapping your face when kicking.

To assist you could apply the following formula:

for the Regular belt (4cm width) :
• (Waist in cm) x 2 + 110 to 120 cm (depending on if you want a standard length belt or long hanging belt. This can in turn be dependent on the amount of embroidery.)

for the Wide belt (4.5cm width):
• (waist in cm) x 2 + 120 to 130cm (depending on if you want a standard length belt or long hanging belt. This can in turn be dependent on the amount of embroidery.)
