Reference matched to the nearest standard foot length entry. Use this as a buying guide, then confirm brand-specific fit and width.

Quick reference table

Most global marketplaces mix at least three different systems on one page. That is why foot length is the safest anchor. This table maps the major consumer formats most people see worldwide.

Why this conversion matters

Shoe sizes are one of the messiest conversion jobs in retail because size labels are short, widths vary and brand fit is inconsistent. A fast converter helps when you are buying online from another region, comparing resale listings, checking sneaker drops, or ordering work shoes and sports footwear from international stores.

The most practical way to cut through the noise is to anchor the comparison to foot length. That is why this tool exposes Japan in centimeters and Korea in millimeters alongside EU, US and UK labels. Those length-based systems are much easier to reason about than guessing whether one country's size 9 behaves like another country's size 9.

Typical use cases

Practical guidance

Use this converter as a fast reference, then check the brand's own fit notes. Material, width, last shape and intended use still matter. A leather boot, a narrow dress shoe and a cushioned running shoe can all behave differently at the same nominal size.
