What This Shoe Size Converter Shows You

A shoe size converter translates a US shoe size into its approximate EU, UK, and centimeter foot-length equivalents, useful when shopping international brands or reading size charts from other regions.

Why Sizing Systems Differ So Much

The US, UK and EU each developed shoe sizing independently, using different reference points and scales – which is why the same physical foot length maps to different numbers across systems.

Why Brand Still Matters More Than Conversion Alone

Even within one sizing system, fit varies by brand and shoe style – a size 10 running shoe and a size 10 dress shoe from different brands can fit noticeably differently. Conversion gets you close; the brand’s own chart gets you exact.

Measuring Your Foot Directly

For the most reliable result, measuring your actual foot length in centimeters and comparing it to a specific brand’s size chart is more accurate than converting between size systems alone.

Shoe Size Converter FAQ

Is this shoe size conversion exact?No, this is an approximate general conversion. Actual fit varies by brand and shoe style, so check the specific brand’s size chart when possible for precision.
Why do men’s and women’s sizes differ for the same shoe?Women’s US sizing is typically about 1.5 sizes higher than the equivalent men’s size for the same foot length, reflecting differences in how the scales were originally set.
How do I measure my foot for the most accurate size?Measure your foot length in centimeters from heel to longest toe while standing, then compare that measurement to the specific brand’s size chart.
Why do EU sizes look so different from US sizes?EU sizing is based on foot length in a different unit system (Paris points), resulting in EU numbers running roughly 30+ points higher than US sizes for the same foot.
Does shoe width factor into this conversion?No, this converts length-based sizing only. Width sizing (narrow, regular, wide) is a separate specification that varies independently by brand.
Is this shoe size converter free to use?Yes, this calculator is completely free, requires no sign-up, and converts sizes instantly in your browser.
