About

Shoe Size Chart is a small free tool for one annoying job: buying shoes across sizing systems without guessing.

Our approach is cm-first. US, UK and EU numbers are labels that each brand stretches a little differently, so every chart here is anchored to foot length in centimetres, using the widely published general international conversions. Where a brand's own published chart differs — Nike's UK column, Adidas' third-sizes — we say so on that brand's page rather than pretending one chart fits all.

We are not affiliated with Nike, Adidas, Converse, New Balance or any other brand named here; those names identify the charts being summarised. Always confirm on the brand's official chart before buying. Shoe Size Chart is built by ORBITFRAME.
