Shoe Size Conversion Chart (AU, US, UK & EU) – CM Guide for Women, Men & Kids
Shoe Size Conversion Chart (AU, US, UK & EU) – CM Guide for Women, Men & Kids
This shoe size conversion chart helps you compare Australian (AU), United States (US), United Kingdom (UK), and European (EU) shoe sizes using approximate foot length measurements in centimetres (CM). Because shoe sizing varies between brands, lasts, styles, and materials, foot length is often the most reliable starting point when converting between different sizing systems.
The most reliable way to compare shoe sizes across AU, US, UK, and EU is to measure your foot length in centimetres. In many cases, AU and UK adult shoe sizes are similar, while US men’s sizes are often about one size higher than AU/UK. Exact sizing can still vary by brand, shoe shape, and fit preference.

📏 How to Measure Your Foot (CM)
Measuring your foot length in centimetres (CM) is one of the most reliable ways to estimate your correct shoe size, especially when converting between AU, US, UK and EU sizing.
- Place a sheet of paper on a hard, flat floor against a wall. Avoid measuring on carpet.
- Stand on the paper with your heel lightly touching the wall.
- Mark the tip of your longest toe on the paper.
- Measure from the wall edge to the mark using a ruler or tape measure.
- Record the measurement in centimetres (CM).
For best results, measure both feet while standing and use the longer measurement. Many people also allow around 5–10 mm of extra room for comfort and natural foot movement before comparing the result to a size chart.

📌 Shoe Size Tips
- Foot length in CM is usually more reliable than converting size numbers alone between regions.
- Measure while standing and compare your longer foot against the CM column.
- AU and UK adult shoe sizes are often similar, but brand-specific differences are common.
- US men’s sizing is commonly about one size higher than AU/UK, although this varies between brands and styles.
- When between sizes, many shoppers choose the larger size and fine-tune fit with socks, insoles, or style selection.
❓ Common Questions
- Is AU shoe sizing the same as UK sizing? In many adult shoe ranges, AU and UK sizes are often similar, but this is not universal across all brands.
- Should I use foot length or my usual size? Foot length in centimetres is usually the more reliable guide, especially when comparing different regions or brands.
- Why do shoe sizes vary between brands? Different brands use different lasts, materials, fit profiles, and sizing standards, which can affect the final fit.
- Should kids’ shoe sizes be chosen by age? Age ranges are approximate only. Foot length is usually a more accurate guide than age.
