How to Measure Your Body for GI Sizing

Accurate measurements are essential for finding your perfect gi size. Follow these simple steps to measure yourself correctly:

  • Height Measurement: Stand straight against a wall without shoes. Mark the highest point of your head and measure from floor to mark.
  • Weight Measurement: Weigh yourself on a reliable scale, preferably in the morning for consistent results.
  • Consider Your Build: If you have a muscular build, consider going up one size. For slender builds, you might prefer a smaller size.
  • Account for Shrinkage: Cotton gis may shrink after washing, so factor this into your size selection.
  • Check Brand Guidelines: Different brands may have slight variations in sizing, so always consult specific brand charts.

Remember that gi sizing can vary between manufacturers. Some brands run larger or smaller than standard sizing. Always check the specific brand’s size chart before making your final decision. A properly fitted gi should allow full range of motion while meeting competition requirements.

Understanding GI Size Standards

Gi sizing follows a standardized system across most martial arts. Adult sizes typically range from A0 to A6, with additional variations like A1L (Long) or A2H (Heavy) for specific body types. The sizing system considers both height and weight to ensure proper fit and functionality.

Youth sizes use a different numbering system, usually ranging from M0 to M4. These sizes are specifically designed for children and teenagers, with proportions adjusted for younger practitioners. Understanding these standards helps ensure you select the right gi category.

Different martial arts may have specific requirements for gi fit and appearance. Competition gis often have stricter sizing guidelines compared to training gis. Our calculator provides recommendations suitable for both training and competition use, helping you make informed decisions for your martial arts journey.
