Shoe Size Conversion

Shoe Size Conversion is a clean, fast tool for matching shoe sizes across the US, UK and EU systems and foot length in centimetres — completely offline. Enter a size in any system, pick men, women or kids, and see every other size at once. WHAT YOU CAN DO • Convert between US, UK, EU and foot length (CM) • Switch between Men, Women and Kids • Enter a size in whichever system you know • Read a full size chart for the selected group • Learn how sizing works and how to measure your foot HOW IT WORKS Every size system is really a measure of length. The app converts everything through one shared value — the length of your foot — using the standard Paris-point (EU) and barleycorn (US/UK) relationships. Common pairs line up the way you would expect, for example Men US 9 is about EU 42, UK 8.5 and 27.0 cm. MEASURE WITH CONFIDENCE The Learn tab shows how to trace and measure your foot at home, then convert that length straight into a size in every system on the Convert tab. IMPORTANT: SIZES ARE APPROXIMATE Shoe fit varies by brand, last shape and style, so two shoes labelled the same size can still fit differently. Use these conversions as a starting point, always check the maker's own size guide, and try shoes on when you can. The app does not guarantee fit. PRIVACY The app collects no personal data and works fully offline — nothing you enter leaves your device. Ads are served by Google AdMob, which may use an advertising identifier (advertising ID) as described in Google's policies. Light and dark themes, a tiny download, and no clutter. Download Shoe Size Conversion and find your size with confidence.
