Shoe Size Conversion – Men, Women, Kids And Foot Length
This shoe size conversion calculator lets you move quickly between US, UK, EU, centimetre and Mondopoint systems for men, women and kids. Because many international charts vary slightly and brands have their own fit, the tool uses rounded, practical values intended for everyday reference rather than custom orthotic work.
How Shoe Size Conversion Works
Most shoe size tables are built around foot length in centimetres. Each system then applies its own offset and step size. Instead of asking you to memorise formulas, this calculator uses internal reference tables for men, women and kids and finds the closest match to the size or foot length you enter.
When you type a size in one system, the tool searches for the nearest row in that category and returns the approximate equivalents, including foot length in centimetres and a Mondopoint value for adult sizes.
Using The Men’s, Women’s And Kids’ Tabs
Each of the first three tabs focuses on a single group:
- Men’s converter – US, UK, EU, centimetres and Mondopoint.
- Women’s converter – US, UK, EU, centimetres and Mondopoint equivalents.
- Kids’ converter – US, UK, EU and centimetres for youth sizes.
You select the system, enter a size and press the convert button. The calculator reports the closest matching shoe size across the other systems and shows the underlying foot length it used. Because half sizes and regional rounding rules differ, your preferred fit might be half a size up or down from the closest table value.
Foot Length To Shoe Size
Many fitters recommend starting from foot length rather than from an existing shoe. In the foot-length tab you:
- Measure foot length in centimetres.
- Choose men, women or kids.
- Optionally add a comfort allowance in centimetres.
The calculator adjusts the length by the allowance, finds the nearest table value and suggests sizes in US, UK and EU for that category. This gives a more neutral baseline when you are switching regions, shopping online or buying for growing children.
Brand Fit And Real-World Variation
Even within the same region and nominal size, shoes from different brands can fit differently. Some lines are cut narrow or wide, some run short or long, and athletic shoes may allow more toe room than formal shoes. The brand tab in this calculator offers short reminders for popular labels so you can decide whether to stay with a familiar size or adjust up or down.
For general body measurements, you can combine this tool with a Height Calculator or a BMI Calculator when you are working through sizing and fit questions for clothing and footwear together.

Frequently Asked Questions
Clear answers about international shoe size conversion, foot measurements, sports sizing, fit accuracy, and when to get a professional fitting.
Shoe brands and retailers use slightly different internal sizing systems, so conversion charts can differ by half a size or more—especially at extreme ranges. This calculator uses practical, rounded averages. Whenever possible, prioritize the brand’s official chart and your personal experience with that brand.
Converting from another shoe that already fits well works best when staying within the same brand or product line. When switching brands, styles or regions, using foot length plus a small comfort allowance provides a more consistent baseline—especially for online orders where trying multiple sizes is harder.
Many people size up slightly for running, hiking or high-impact activities to allow for natural swelling and thicker socks. The ideal adjustment depends on terrain, sock thickness and personal preference, so treat the calculator's output as a starting point rather than a strict rule.
This tool is great for everyday sizing guidance and online shopping. For specialized footwear—such as technical hiking boots, ski boots or medical orthotics—a professional fitting with an experienced specialist is still the most reliable way to ensure comfort and precision.
