Frequently Asked Questions
Which size system is the most accurate?
Japanese (JP). It uses cm directly for shoes and body measurements with no abstraction. EU is second-most accurate; US is least, due to vanity sizing.
Does this calculator handle every brand?
It handles regional standards. Brand-specific calibration (slim vs relaxed cuts, vanity offsets) is shown in our brand-specific guides.
Why do Asian sizes run smaller than US?
Asian standards are calibrated for the average Asian body, which historically runs smaller and slimmer than the average American body.
How do I use this for online shopping?
Find your size in your home region. Use the converter to get the equivalent in the brand's region. Cross-check the brand's own chart for vanity offsets.
