Shoe Size Converter
Convert adult shoe sizes between US Men, US Women, UK, EU and foot length in centimeters.
How to Use the Shoe Size Converter
Choose a known shoe size or foot-length reference and compare approximate US, UK, EU and centimeter sizes. Use the chart as a guide when shopping across regions.
Practical Example
A men’s US size 9 is commonly close to UK 8 and EU 42, though brand charts may differ.
Factors That Affect Shoe Fit
Brand sizing, shoe last, width, toe shape, socks and foot swelling can all affect fit. Always check the manufacturer’s size chart when possible.
Frequently Asked Questions
Are international shoe size conversions exact?
No. They are approximate because brands and sizing systems use different increments.
Should I use foot length?
Yes. Foot length is often the most useful reference when converting between systems.
Do men’s and women’s US sizes match?
No. US men’s and women’s numbering usually differs.
Understanding Shoe Size Conversions
Shoe size labels differ across US, UK and EU systems, and brand-specific lasts can create additional variation. Foot length in centimetres is often the most useful neutral measurement when comparing size charts.
Measure both feet while standing and use the larger measurement. Width, sock thickness and intended fit also matter, so verify the converted size against the manufacturer’s own chart before purchasing.
Conversion Details and Practical Limits
Length unit conversion uses fixed relationships, but displayed precision should match the source measurement. Converting a rounded value to many decimal places does not make it more accurate, so final results should be rounded appropriately for the measurement context.
