How do I convert US shoe size to EU?

For men, add approximately 33 to your US size (e.g., US 10 = EU 43). For women, add approximately 31 to your US size (e.g., US 8 = EU 39). These are approximations — use our converter for exact values across the full size range, as the offset varies slightly at different sizes.

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

US women's sizes are approximately 1.5 sizes larger than men's sizes for the same foot length. A US men's 8 is roughly equivalent to a US women's 9.5. However, the width also differs — women's shoes are typically narrower (B width) compared to men's (D width).

How do I find my shoe size from foot length in CM?

Measure your foot from heel to longest toe while standing. The measurement in centimeters is your JP shoe size directly. For US men's, use roughly (CM - 18) / 1.0 for adult sizes around 25-30 cm. For EU, multiply the CM measurement by 1.5 and add 2. For the most accurate result, use our converter tool above.

How do UK and US shoe sizes compare?

For men, UK sizes are approximately 0.5 to 1 size smaller than US sizes (e.g., US 10 = UK 9.5). For women, the difference is larger — UK sizes are about 2 sizes smaller than US women's sizes (e.g., US Women's 8 = UK 6). UK and US kids' sizes are the same for smaller children but diverge for older kids.

Do EU shoe sizes differ between men and women?

No. The European shoe sizing system is unisex — a EU 42 represents the same foot length whether it is a men's or women's shoe. The difference lies in the shoe's width and shape, not the numbered size. This makes EU sizing simpler for international conversions.

How do children's shoe sizes work?

Children's shoe sizes use a separate scale from adults. In the US and UK, kids' sizes run from 0 (newborn) to 13, then reset to 1 for adult sizes. EU kids' sizes run continuously from about 16 (infant) up to 39-40 where adult sizing begins. JP sizes for kids are simply the foot length in CM, just like adults. Our converter handles kids' sizes separately for accurate results.

Shoe Size Converter

Shoe sizing varies wildly between countries and even between brands. A US men's 10 is a EU 43, a UK 9, and a JP 28 — but those numbers are nearly impossible to memorize across all size ranges. Our shoe size converter eliminates guesswork by converting any shoe size between four major international systems (US, EU, UK, JP/CM) for men, women, and children. Enter a size in any system and instantly see the equivalent in all others. The converter handles half sizes accurately and includes a complete reference chart covering the full range of adult and kids sizes. Whether you are shopping internationally, buying shoes online from a foreign retailer, or just trying to figure out your partner's size in a different system, this tool gives you the answer in one click.

footprint How to Measure Your Foot

Place paper on floor

Tape a piece of paper against a wall on a hard floor.

Stand on the paper

Stand with your heel against the wall. Wear the socks you normally wear with shoes.

Mark longest toe

Have someone mark the tip of your longest toe on the paper.

Measure in CM

Measure from the wall to the mark. Use this CM value with JP system above.

tips_and_updates Tips

• Always measure your feet in the afternoon — feet swell during the day and can be up to half a size larger by evening
• Stand when measuring your foot length for the most accurate result, as your foot spreads under body weight
• If you are between sizes, go up to the next half size rather than down for a more comfortable fit
• Different brands may vary by up to a full size even within the same sizing system — use CM measurements when buying unfamiliar brands
• Children's shoe sizes use a different scale than adults — do not assume kids' sizes convert the same way
• EU sizes do not differ between men and women — a EU 40 is the same length regardless of gender
• When shopping from Japanese retailers, JP sizes equal your foot length in centimeters, making them the most straightforward system
• Leave about 1 cm (roughly a thumb's width) between your longest toe and the front of the shoe for proper fit

The Formula

Shoe size systems are based on foot length in centimeters. The JP system directly equals foot length in CM. US sizes use the Brannock device formula: US Men = (3 × foot_length_inches) - 22, which translates to approximately (CM - 22.5) / 0.847 + 1. EU sizes use Paris points (2/3 cm each): EU = CM × 1.5 + 2. UK sizes are approximately US Men - 0.5 for adults. Women's US sizes are typically 1.5 sizes larger than men's for the same foot length.

There are four major shoe sizing systems used worldwide. The US system (Brannock scale) is used in the United States and Canada, with separate scales for men, women, and children. The EU system (French Paris point) is used across Europe and is unisex — a EU 42 is the same length for men and women. The UK system is used in Britain, Ireland, Australia, and New Zealand, and is similar to the US system but offset by about 0.5 to 1 size for men. The JP system, used in Japan and much of East Asia, is the simplest — it equals the foot length in centimeters. All systems ultimately map to foot length, making centimeters the universal translation layer.

Even within the same sizing system, a size 10 from Nike may feel different from a size 10 from Adidas. This is called vanity sizing or last variation — each brand uses slightly different shoe lasts (foot-shaped molds) and may round sizes differently. The best way to ensure a good fit when buying from an unfamiliar brand is to measure your foot length in centimeters and compare it to the brand's specific size chart. Our converter provides the standard industry conversions, which work as a reliable starting point for most major brands.
