Confused about sizes? First time buying a uniform? Let me help you!
First, be sure to identify your height.
For kids under 140cm, their weight generally is an indication of what size to get, as they don't vary in size much.
Some customers choose to take up the pants/sleeve so that they can use the Gi for a longer period of time.
Children: AFK/AFKB/AMJ/AMJB/AMJO/AMJBO models
Kids generally do not vary that much (in terms of size/height)
In my experience,
110cm - For kids about 15 - 20kg - AFK/AFKB Models
120cm - For kids about 20 - 30kg - AFK/AFKB Models
130cm - For kids about 30 - 40kg - AFK/AFKB, AMJ/AMJB/AMJO/AMJBO Models
140cm - For kids about 40 - 50kg - AFK/AFKB, AMJ/AMJB/AMJO/AMJBO Models
150cm - For kids about 50 - 60kg - AFK/AFKB, AMJ/AMJB, ATG/ATGB, ALL IJF Gi
160cm - For kids about 60 - 70kg - AFK/AFKB, AMJ/AMJB, ATG/ATGB, ALL IJF Gi
170cm - For kids about 70 - 80kg - AFK/AFKB, AMJ/AMJB, ATG/ATGB, ALL IJF Gi
180cm - For kids about 80 - 90kg - AFK/AFKB, AMJ/AMJB, ATG/ATGB, ALL IJF Gi
Adults: ALL IJF Gi, ATG/ATGB, AMJ/AMJB models
In most cases (if no half sizes available), you should take your height and choose the next smallest size down. i.e 169cm -> choose size 3 (160cm)
Slim fit models are available, for those slightly below the weight range as per above -
Eg: 185cm tall and approx 70kg? - 180cm Slim fit recommended
Slightly above the weight range?
Eg 185cm tall and approx 95kg+? - 180cm M recommended (DanRho Sensei M, Ultimate M/ATG)
Half sizes are slightly tricky -
If you're 167cm tall I would recommend getting a 160cm for a better fit - but you may prefer the size 165cm (3.5). Either way, you'd fit both.
If you're too close to the nearest size i.e 171/172cm, think about getting the 165cm for a close fit (instead of the 170cm)
Please note that the recommendations above are suitable for most cases. if you're unsure, please ask us and we'll be sure to assist you!
