Hakama sizes are based on a simple formula. If you know the length or your outseam, which is the distance from your belt to your ankle, then you can calculate what size hakama to get with this simple formula. Simply divide the inches by 1.49 (or the centimeters by 3.79). So, if your outseam measures 40 inches, your hakama size would be around a size 27. However, if you are buying a cotton hakama, the hakama will shrink some. So, you may want to get a hakama one size larger to compensate. Then, wash the hakama before you wear it the first time to allow it to shrink down to size. Even if you order a polyester or tetron hakama, you may want to go a size larger and then have someone tailor it for you.
Here’s a chart of hakama sizes.

Another thing to take into consideration is your body type. Women, for example, often tie the hakama above the hip bone whereas men tend to tie it around the depression midway up the hip bone. Also, if you have a bit of a belly (like I do 😳 ) the front of your hakama may rest lower than the back. So, the length along the outseam will be slightly longer than the length in the front. If that’s the case, you can factor the difference in when choosing your hakama size or a better alternative might be to have someone tailor the hakama for you.
