Judo uniform (judogi)
For those who are planning on competing on the local or national level, it is important that your gi fit within the rules set down by the IJF. Here is the list of rules governing the size of judo gi worn by competitors:
a) |
Strongly made of cotton or similar material (see guideline), in good condition
(without rent or tear). The material must not be so thick or hard or slippery as to prevent the opponent from taking a grip. |
b) |
Blue for the first contestant and white or off-white for the
second contestant. (See Appendix). |
|
| |
1) |
National Olympic abbreviation (on back of jacket). Size
of the letters 11 cm. |

100cm2. |
| |
3) |
Manufacturer's trade mark (on bottom-front of jacket, on
bottom front of left leg of the trousers and on one end of
the belt). Maximum size 20 cm2.
It is permitted to place the manufacturer's trade mark on
one of the sleeves but inside the 25cm x 5cm area instead
of at the bottom front of the jacket. The IJF Official suppliers
are allowed to place the IJF Logo above their trade mark (in
direct contact). |
| |
4) |
Shoulder markings (from collar - across shoulder down the
arm - both sides of jacket). Maximum length 25cm and maximum
width 5cm. (The same advertising or national colours on both
sides) |

Advertising on the sleeves, 10 cm x 10 cm on each sleeve
(different advertising allowed). These 100 cm2 have to be
fixed just below and in contact with the stripes of 25 cm
x 5 cm. |
| |
6) |
Indication of the placing (1st, 2nd, 3rd) at the Olympic
Games or World Championships, in an area of 6cm x 10cm at
the bottom front left side of the jacket. |

The contestant's name may be worn on the belt, lower front
of the jacket and upper front of the trousers up to a maximum
of 3 cm x 10 cm. Also the contestant's name or abbreviation
may be placed (printed or embroidered), on the back of the
jacket above the National Olympic abbreviation, but in no
case in a position to prevent an opponent from grasping the
back of the jacket. The letters can be up to a maximum of
7cm high and the length of the name can be up to a maximum
of 30cm long. This 7cm x 30cm rectangular area must be located
3cm below the collar of the jacket and the back identification
must be fixed at 4cm below this area.
Note: For IJF Events and the Olympic Games, the names are
indicated on the 30 cm x 40 cm Bibs. |

extended downwards at the sides of the body. The body of the
jacket shall be worn with the left side crossed over the right
and shall be wide enough to have a minimum overlap of 20cm
at the level of the bottom of the rib-cage. The sleeves of
the jacket must reach to the wrist joint at the maximum and

the control. |
