## FAQ

### How do clothing sizes differ between countries?

A size number is a regional label, not a measurement. A US women's 8 is roughly a UK 12, an EU 40, and a JP 11. Our converter maps your measurement onto each region's scale so the number means the same body everywhere.

### How accurate is the bra size calculator?

It uses the standard underbust (band) and bust (cup) method: the band is the underbust rounded to the nearest even number, and each 2.5 cm of bust-over-underbust difference adds one cup letter. It is a reliable starting fit; sister sizes help fine-tune tightness.

### Can I find my size from body measurements?

Yes. Enter bust, waist, and hip for clothing or underbust and bust for bras, and the tool returns a recommended size in US, UK, and EU. Measuring your body is more reliable than trusting a brand's tag.

### Does the shoe converter cover width and kids?

It converts women's, men's, and kids' shoe sizes across US, UK, EU, centimetres, and millimetres. Width (narrow or wide) is not standardised across countries, so the result is the length-based size.

### Is my measurement data stored?

No. Every conversion and calculation runs locally in your browser. Your measurements are never uploaded, logged, or shared, so you can use the studio without an account.

### Why do Asian sizes run smaller?

Japanese and some other Asian size scales are built around smaller average body measurements and use centimetre-based numbering. The converter applies those regional offsets so a JP 11 lands near a US 8 rather than a mismatched size.
