Use this form to help you with your calculations. It is my best way of helping you find the correct size for your gi. It is not perfect so you need to double check your measurements and see if they match up with reality for you. Use an existing pair of pants or items of clothing to help.
It is also suggested that whatever RESULTS processed for any particular field, you ROUND UP. Better to have more space, than too little.
If you have any questions I will do my best to help but this system is not perfect and everyone has a different body.
I want you to have a gi that will work for you and this is my best attempt to make it happen.
Once you click submit, it will be emailed to your address and you can use the results to fill out the form found at the link.
