Convert the label on a shoe

Choose your current size system, the system you want, and your shoe size. Leave Brand on General reference for an approximate starting point, or choose a brand for its published labels. For UK and EU inputs, select the men’s or women’s chart that matches your shoe.

An approximate starting point from Zappos, not a universal sizing standard. Choose a brand when you know it. Ranges and multiple matches are retained.

An example from this chart

US men 9, UK 8.5, and EU 42 in the general men’s reference.

How the conversion works

The converter looks up the labels listed together in the selected chart. It preserves fractions, ranges, and multiple matches. It does not estimate missing sizes or infer a cross-gender equivalent that the chart does not provide.

Current guide: General men’s reference.

A size label is not a foot measurement. For measuring instructions and model-specific fit advice, use the linked guide. A matching regional label does not guarantee matching width or fit.

This tool runs in your browser, with no account or size history. Charts were checked on October 3, 2026. If a manufacturer’s current labels differ, follow its latest product guide.

FAQs

Does this work for every brand?

Start with the approximate general reference, or select one of the available brand charts. Brands, styles, and widths can fit differently. Use the product’s own guide before buying.

Why does an EU size include a third?

Some manufacturers use fractional EU labels. The converter preserves them exactly instead of rounding to another size.

Can I enter my foot length?

This tool converts an existing size label. For foot measurements and fitting, use the linked manufacturer guide. A shoe-size label is not a foot measurement.

Why do I see multiple sizes or no equivalent?

Some charts assign several sizes to one label, or omit a system entirely. The converter shows the listed matches and leaves missing mappings unavailable, rather than guessing.

Are children’s sizes included?

No. Adult and children’s systems differ. Use the child-specific guide for the shoe you are buying.
