How accurate are international shoe size conversions?

Our free shoe size converter uses industry-standard conversion tables based on foot length measurements in centimeters. While conversions are highly accurate, shoe fit can vary between brands and styles. We recommend checking specific brand size guides when available and considering that some manufacturers may use slightly different sizing standards.

What's the difference between men's and women's shoe sizes?

In the US sizing system, women's sizes are typically 1.5 to 2 sizes larger than men's for the same foot length. For example, a women's US size 8 is approximately equivalent to a men's US size 6.5. This difference varies by region - UK sizes differ by about 1.5 sizes, while EU sizes are unisex and based solely on foot length in centimeters.

How do I measure my foot for accurate shoe size conversion?

To measure your foot accurately: Stand on a piece of paper, trace your foot outline, and measure from heel to longest toe in centimeters or inches. Measure both feet and use the larger measurement. It's best to measure in the evening when feet are slightly larger. Enter this measurement in our free converter tool to find your size in any international sizing system.

Why are shoe sizes different between countries?

Different countries developed their own shoe sizing systems historically. US and UK sizes are based on barleycorn measurements, EU sizes use the Paris point system (centimeters × 1.5), Japanese and Korean sizes use direct centimeter measurements, and Chinese sizes use millimeters. Our free tool converts between all these systems accurately.

How to Measure Your Feet

Foot length is the most reliable way to find your size in any system. Measure late in the day when feet are largest.

Trace your foot

Place a sheet of paper against a wall and stand on it with your heel touching the wall. Trace around your foot or mark the tip of your longest toe.

Measure the length

Measure from the wall (heel) to the longest toe in centimetres or inches. This is your foot length.

Use the larger foot

Measure both feet. They are rarely identical, so use the larger measurement to choose your size.

Enter it above

Type your foot length into the "Or Foot Length" box to get your size in every region instantly.

Note: Shoe sizing is not perfectly standardised — the same labelled size can fit differently between brands, styles and materials. Use these conversions as a starting point and check a specific brand's size guide when available.

💡 Shoe Sizing Tips

Measure Your Feet: Always measure both feet in the evening when they're slightly larger. Use the larger measurement.
Brand Variations: Sizing can vary between brands. When possible, check brand-specific size guides.
Width Matters: This converter focuses on length. If you have wide or narrow feet, consider width fittings (D, E, EE, etc.).
Sock Thickness: Consider the type of socks you'll wear with the shoes when selecting your size.
Try Before Buying: If ordering online internationally, check the return policy in case the fit isn't perfect.
Children's Shoes: Leave about 1cm (0.4 inch) growing room for children's shoes, but not more to ensure proper support.
