Quick answer: EU sizing relates to inner circumference, but a jeweller should confirm the final fit.
Step-by-step
- Start from actual measurements rather than the label you usually buy.
- Check which body or product dimension the value refers to.
- Compare the result with the exact product chart and read the cut information.
Worked example
Example: if your measurement sits at the upper edge of size M and the fabric is rigid, compare L as well. With stretch fabric and a close-fitting design, the decision may be different.

Key limitations
There is no universal size that works across every brand. Garment ease depends on cut, material and purpose. A general converter is a starting point, not a fit guarantee.
Best next step: Enter the measurement in a calculator, then compare the result with the store chart.
FAQ
Is a general chart result final?
No. The exact product chart and actual garment measurements take priority.
Do I need to measure every time?
Not always. Update the profile after body changes, for growing children and before buying an unusual cut.
Is choosing the larger size always safer?
No. It can worsen shoulder, waist, protective-gear or helmet fit. Check the limiting measurement.
