How to Figure Out What Size Hakama to Get

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.

Size Length Size Length
16 61 cm / 24 in. 16.5 63 cm / 25 in.
17 64 cm / 25 in. 17.5 66 cm / 26 in.
18 68 cm / 27 in. 18.5 70 cm / 28 in.
19 72 cm / 28 in. 19.5 74 cm / 29 in.
20 76 cm / 30 in. 20.5 78 cm / 31 in.
21 80 cm / 32 in. 21.5 82 cm / 32 in.
22 83 cm / 33 in. 22.5 85 cm / 33 in.
23 87 cm / 34 in. 23.5 89 cm / 35 in.
24 91 cm / 36 in. 24.5 93 cm / 37 in.
25 95 cm / 37 in. 25.5 97 cm / 38 in.
26 99 cm / 39 in. 26.5 101 cm / 40 in.
27 102 cm / 40 in. 27.5 104 cm / 41 in.
28 106 cm / 42 in. 28.5 108 cm / 43 in.
29 110 cm / 43 in. 29.5 112 cm / 44 in.
30 114 cm / 45 in.

These hakama sizes come from the kujira shaku sun1 2 system where 1 sun = 1.49 inches and 10 sun = 1 shaku. So, size 25, for example, would have been interpreted as 2 shaku and 5 sun.

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.



I started practicing Aikido in 2000. It instantly became one of my main interests. And the rest is history.

    I am going to buy the a hakama soon and I am worried I may order the wrong size. I am 6 feet tall my waist is 37. Pant size is 38 x 32.

    Can you please recommend a hakama size for these measurements? Thank you!

  2. admin says:

    You’d probably be in the range of a size 29, but you should measure your outseam to be sure.

    Hello. I am 6ft as well pants size 40×32 wondering if you could help me too

    Devin, I’m afraid measuring your outseam is really the only reliable way to know for sure what your hakama size is. Another way to approach the measurements is to measure from the point where the bottom of the front himo (strap) would be (on the side of your body) to the point where the bottom of the hakama would fall. It’s easy to measure your outseam. Just get a tape measure for measuring fabric and have somebody help. Alternatively, you can go to a tailor or any place that sells suits and ask them to do it for you.

    Hi, I’m thinking of doing a cosplay of a Manga character from Bleach, and they wear Hakama. I can’t buy since I’m too young. I just want some tips from you since you seem to know a lot about Hakama.
    My outseam is 58 cm if I’m correct. But I would also like some other measurements please? :3
    Also if you know some cloth that don’t wrinkle too much, but still looks good for a Hakama?

    Sorry, my outseam is ~90cm!

  10. Justin says:

    Hello. I am about 6’4″ tall and weigh roughly 300 pounds. I’ve been looking into getting a Hakama recently and I’m just doing research here. Some Hakama makers give extensions to tying the Hakama on, but I’m curious if I’d need it as it costs extra. My pant size is 48×32. I’m a pretty hefty fellow. Thanks!
