- Check the manufacturer’s chart before purchasing.
How to measure your feet
Stand on paper with your heel lightly touching a wall. Mark the end of the longest toe and measure from the wall to the mark. Repeat for both feet and use the longer measurement. Keep the ruler straight and measure while wearing the type of socks normally used with the shoes.
Foot length is not the same as the inside length of a shoe. Manufacturers add toe room and shape their lasts differently. The Shoe Size Converter therefore gives a practical starting estimate, not a universal guarantee.
Shoe Size Converter method
The converter uses a reference table in half-size increments from approximately 22 to 31 centimeters. A value entered in any supported system is matched to the nearest reference row. Inches are converted to centimeters using:
centimeters = inches × 2.54
US women’s sizes are approximately 1.5 sizes above the corresponding US men’s size in this reference. UK and EU relationships are based on commonly published adult conversion ranges. Brands can shift by half a size or more because there is no single worldwide fit standard.
Worked example
A 26 cm foot matches approximately US men’s 8, US women’s 9.5, UK 7.5 and EU 41. The same foot length is about 10.24 inches. A wide last, pointed toe or thick lining may require a different choice.
Why shoe sizes vary
Sizing labels describe a brand’s intended fit rather than an exact physical dimension. Athletic, dress and safety footwear may use different internal space. Width codes also vary, and children’s scales should not be inferred from adult conversions.
For online orders, compare the measured length with the exact product page, read fit reviews and check the return policy. Re-measure periodically because socks, insoles and foot swelling can affect comfort. The Shoe Size Converter is most useful as a consistent comparison point before brand-specific verification.
The National Institute of Standards and Technology explains standard length units and conversions. Use a retailer or manufacturer size chart for the final purchase decision.
Frequently asked questions
The Shoe Size Converter offers approximate adult equivalents for common international systems.
Should I round up or down?
When between sizes, review the brand’s advice and the shoe shape. Many shoppers try the larger size when additional toe room is needed.
Does this include shoe width?
No. Length and width are separate fit dimensions. Check narrow, standard and wide options with the manufacturer.
Can I use the converter for children?
No. Children’s and youth sizing follows different scales. This page is designed for adult sizes.
Why does another chart show a different EU size?
Conversion tables use different rounding and brand assumptions. A difference of half or one EU size is common.
Which foot should I use?
Use the longer foot because small left-to-right differences are normal.
