Aikido Hakama Size & Comparative Chart
As an expert in the manufacture of aikido equipments, Seido can provide you with the technical details and sizes of all its models. These measurements correspond to the measurements out of the workshop, not including shrinkiage (for Aizome models). Note that our Hakama are hand crafted, so slight variations are possible. All measurements are in centimeters and kilograms.

* Standard Tetron Hakama (AH300) has its own belt lengh chart. Please consider the product page for details.
* The measurement of the Hakama length is made from below the bottom of the front strap, to the bottom of the hakama. The Nobakama is usually worn a size shorter than the traditional hakama.
How to Choose your Size
1 - Hakama Length
Size corresponds to the ancient Japanese "Kujira-shaku" system used mainly in the manufacture of traditional clothing.
1 Kujira-shaku = 3.79 cm - A hakama size 27 is therefore 27 x 3.79 = 102.3 cm
This length is measured from the bottom of the front strap to the bottom of the Hakama at its center. Unlike Iaido or Kendo, Aikido Hakama are adjusted to be worn with a thinner belt (Judo-type belt).
Traditionally, Hakama should fall just above the external ankle, however, in Aikido, it is common to wear longer hakama. The sizes we suggest above are for a "long" port (below the lateral ankle).
To make your choice, we recommend you wear a friend's Hakama and check its length, depending on your preferences but also on your body type (including the position of your hips and the length of your legs).
If you wear a traditional "Obi" i.e. a wide belt (kakuobi type), we advise you to contact us so that we adapt your order where the lengths of the front and rear will be adapted to the use of this type of Obi.
Finally, please note that this system of size (25, 26, 27 etc.) is broadly used in Japan only. When you try the hakama of a friend, make sure that it is a hakama "made in japan", or measure the front yourself.
2 - Strap lengths
The length of the Seido Hakama straps is 400 cm at the front and 180cm at the back until the size 24.5 and 420 cm and 200 cm from size 25.
Check the length of the straps:
- Front strap : "waist size" x 4 + ~80 cm"
- Back strap : "waist size x 2 + 20~30 cm"
Standard Seido Hakama can be worn up to 90~95 cm in waist
For practitioners with waist measuring more than 90 ~ 95cm, and to avoid disharmony in the port of Hakama, we advise a made to measures manufacturing. Not only the straps will be perfectly adapted to your waistline, but the front, back, and Koshiita will be expanded. For practitioners over 115cm waist, we can also offer custom "extra large" size.
How to Choose your model
Hakama fall into two categories, synthetic fabrics (Tetron, Polyester, Polyester/linen) and 100% cotton (black/navy or Aizome)
Synthetic models are easier to maintain, have extremely low bleed through (or not), the pleats last longer, and they are generally lighter than cotton models.
The 100% Cotton models are more difficult to maintain and should be carefully folded after each class. They are heavier and slower to dry. However, they are more "traditional" and almost indestructible.
Aizome cotton rubs off a lot and requires special treatment explained in the section "How to take care of your equipment".
However, the black/navy cotton model does not fade. This is a good compromise between synthetic models and traditional Aizome dying.
