Jersey Size Calculator & Fit Guide

Use our jersey size calculator to find the right size in under a minute. It’s built to help you choose the best fit for a Japan jersey (Japan football jersey / Japan soccer jersey), and it also works for anime jerseys, national team jerseys, concept designs, and most football shirts across the store.

How to use the size calculator

  1. Measure your chest (most important).
  2. Enter your height and weight.
  3. Select your preferred fit: regular, slim, loose, or performance.

Your result will show a recommended size based on the information you provide and the size chart used by our jerseys.

How to measure your chest correctly

  • Stand straight with your arms relaxed.
  • Wrap the tape around the fullest part of your chest, under the armpits.
  • Keep the tape level and snug (not tight).
  • Record your measurement in cm or in.

Between two sizes?

If you’re between sizes, choose based on how you want to wear your jersey: size up for comfort or layering, and choose the smaller size for a closer fit.
