How to measure for Birkenstock
Birkenstock sizes are native EU sizes; measure heel-to-toe standing (barefoot is most accurate for sandals), using the longer foot.
Birkenstock fit guidance
Birkenstock's own official conversion is US size + 31 = EU size (women's) or US size + 33 = EU size (men's). UK conversions vary meaningfully between retailers, so UK sizing is not shown here -- buy by EU size where possible. Birkenstock sizes children in EU, exactly as it does adults — the EU number is what is printed on the footbed and is the reliable column. Birkenstock publishes each children's size against a PAIR of US sizes (an EU 24 is listed as a US 6-6.5); the lower of each pair is shown here, so treat the US figure as approximate and the EU as definitive. Their children's range starts at a 15cm foot.
