How to Measure for Karate Belt Size

Measuring correctly is crucial for finding your perfect karate belt size. Here’s a step-by-step guide to ensure accurate measurements:

  • Stand straight with your feet shoulder-width apart
  • Wrap a flexible measuring tape around your waist at the natural waistline
  • Keep the tape snug but not tight – you should be able to breathe comfortably
  • Ensure the tape is parallel to the floor and not twisted
  • Record the measurement to the nearest half-inch for best accuracy

For karate practitioners, the belt should sit comfortably around your gi (uniform) without being too loose or restrictive. Consider that your gi adds some bulk to your waist measurement.
