About this tool
Shoe size conversion is essential for online shopping from international retailers, buying shoes while traveling, understanding sizing when moving between countries, and purchasing footwear gifts for people who use different sizing systems. Different countries use different shoe size standards: the US has separate men's and women's scales, the UK uses a different numbering system, continental Europe (EU) has its own scale, and many Asian countries use centimeters. These systems have different origins and numbering, making conversions necessary but sometimes approximate.
Our Shoe Size Converter helps translate between the major sizing systems: US (separate scales for men, women, and children), UK (sizes run about one number smaller than US), EU (uses larger numbers, typically 30-50), and centimeter measurements (foot length in cm). The calculator uses standard conversion tables based on typical manufacturer sizing, though actual fit can vary by brand, style, and country of manufacture.
Understanding shoe size conversions helps when: shopping on international websites (Amazon.co.uk vs Amazon.com), buying shoes while traveling abroad, purchasing footwear from European or Asian brands, reading size charts on product pages, comparing sizes when you know your size in one system but need another, and avoiding costly returns from incorrect sizing. For example, a US Men's size 10 is approximately UK 9, EU 43, or 27.5 cm.
The converter is valuable for frequent travelers, online shoppers buying from international retailers, people purchasing gifts for others, parents buying children's shoes (which have different conversion tables), fashion enthusiasts following international brands, and anyone confused by sizing differences. Note that conversions are approximate—brands vary, and trying shoes on is always best. When in doubt, measure your foot length in centimeters for the most accurate reference.

FAQs
How accurate are shoe size conversions?
Shoe size conversions are approximate because different brands and countries have slight variations. Conversions are based on industry-standard tables, but actual fit depends on shoe brand, style, width, and manufacturing country. Italian brands often run small, while American athletic shoes may run large. Always check brand-specific size guides when available.
What is the difference between US men's and women's sizes?
US women's sizes are typically 1.5-2 sizes larger than men's for the same foot length. A men's size 8 is approximately a women's size 9.5-10. This is because women's shoes historically used a different sizing scale. For unisex shoes, the men's sizing is usually indicated—convert accordingly if you normally wear women's sizes.
How do I measure my foot in centimeters?
Stand on paper, trace your foot outline, and measure from heel to longest toe in centimeters. Do this in the evening when feet are largest. Add 0.5 cm for comfort. This measurement is the most accurate way to determine size, especially for international purchases. Many online retailers provide cm-to-size conversion charts.
Why do UK sizes differ from US sizes?
UK and US sizing systems evolved separately with different starting points and increments. UK sizes run approximately one size smaller than US sizes for men, and 2-2.5 sizes smaller for women. The UK system is based on barleycorns (1/3 inch increments), while the US system has a different historical basis.
What are EU shoe sizes based on?
European (EU) sizes are based on the Paris point system, where sizes increase by 2/3 of a centimeter (6.67 mm) per size. The number roughly corresponds to the foot length in Paris points. EU sizes are unisex (same scale for men and women), though some manufacturers use gender-specific sizing. EU sizes typically range from 35-48 for adults.
Should I size up or down when between sizes?
Generally size up, especially for athletic shoes or if you have wide feet. It's easier to use insoles or thicker socks than to stretch too-small shoes. However, some materials (like leather) stretch over time. Check reviews for whether a specific shoe "runs large" or "runs small." Consider the shoe type: dress shoes are typically more fitted than sneakers.
Are children's shoe sizes the same internationally?
No. Children's sizes vary significantly between countries and have additional complexity with infant, toddler, and youth categories. US children's sizing has separate infant (0-13) and youth (1-7) scales. UK and EU have different systems. Always measure a child's foot length in cm for the most reliable fit, as children's feet grow quickly.
What if a website only shows US sizes but I know my EU size?
Use this converter to find your US equivalent, but also check if the website has a size guide. Some international retailers display US sizes but manufacture to European standards. If possible, find your foot length in cm and use the retailer's size chart. Read reviews to see if others found the sizing true-to-size.
