Shoe Sizing by Country and Region

United States Sizing

The United States uses a unique sizing system based on the Brannock Device, which measures foot length and width. US sizes are expressed in whole and half sizes, with separate scales for men, women, and children. Men's sizes typically start at 6 and extend to 16, while women's sizes generally range from 5 to 12. The US system is also used in Canada.

United Kingdom Sizing

The United Kingdom sizing system is similar to the US system but uses different numerical values. UK sizes run approximately 0.5 sizes smaller than US men's sizes and about 2 sizes smaller than US women's sizes. The UK system is also used in Australia, New Zealand, and other Commonwealth countries, though Australia sometimes uses US sizing for athletic footwear.

European Sizing

European (EU) sizing, also known as Continental or Paris Point sizing, is based on the length of the last (shoe form) measured in Paris Points. One Paris Point equals two-thirds of a centimeter (6.67mm). EU sizes are expressed as whole numbers typically ranging from 35 to 48 for adults. This system is used throughout continental Europe and has been increasingly adopted in Asian markets.

Centimeter (Mondopoint) Sizing

Centimeter-based sizing measures the foot length directly in centimeters or millimeters. This system, sometimes called Mondopoint, is commonly used in Japan, Korea, and other Asian countries. It is considered the most accurate sizing method as it corresponds directly to measured foot length. The Mondopoint system is also used for ski boots and military footwear internationally.

For conversions between these systems, the International Size Converter provides accurate translations. Size charts for specific conversions such as EU to US and US to UK are also available.

Brand Sizing Variations

Shoe sizes are not standardized across all manufacturers. Variations of up to one full size can exist between brands due to differences in last shapes, design philosophy, and target markets. The following factors affect how shoes fit:

  • Last Shape: The three-dimensional form used to construct the shoe determines its overall shape and fit characteristics.
  • Material: Leather shoes often stretch and conform to the foot over time, while synthetic materials maintain their original shape.
  • Style: Athletic shoes typically run larger than dress shoes. Boots may require sizing up for thicker socks.
  • Width: Standard sizing assumes a medium (D for men, B for women) width. Narrow and wide options may affect length fit.
  • Country of Origin: European brands may size differently than American brands even when using the same system.

Important Note

Size conversions provided on this website represent industry-standard equivalents. Actual fit may vary by brand and style. Trying shoes on before purchase is recommended when possible. Retailer return policies should be reviewed when purchasing online.

How to Measure Foot Length

Accurate foot measurement is essential for determining correct shoe size. The following steps are recommended for measuring foot length at home:

  1. Prepare materials: A piece of paper larger than the foot, a pencil, and a ruler or measuring tape are needed.
  2. Position the foot: The foot should be placed flat on the paper while standing. Weight should be distributed evenly on both feet.
  3. Trace the foot: The outline of the foot should be traced with the pencil held vertically. The pencil should remain in contact with the foot throughout.
  4. Mark the extremes: Straight lines should be drawn at the heel and at the longest toe, perpendicular to the length of the foot.
  5. Measure the distance: The distance between these two lines represents the foot length. Both feet should be measured, as they often differ in size.
  6. Measure at the right time: Feet swell during the day. Measuring in the afternoon or evening provides the most accurate size for all-day comfort.

The Foot Length Calculator converts measured length to shoe sizes in multiple systems.

Measurement Tolerance

A margin of error of 3-5 millimeters is normal in home measurements. When foot length falls between sizes, the larger size is typically recommended. Socks and intended use (athletic vs. casual) should also be considered when selecting size.

Frequently Asked Questions

  • Standard conversions provide a reliable starting point but are not guaranteed to produce a perfect fit. Accuracy typically falls within half a size of the true equivalent. Variations between brands, styles, and individual foot shape affect final fit. Trying shoes on remains the most reliable method for ensuring proper fit.

  • Shoe sizes are not globally standardized. Each manufacturer uses their own lasts (foot forms) and may interpret size standards differently. Factors including target market, shoe style, and country of origin contribute to variation. Athletic shoes, dress shoes, and boots from the same brand may also fit differently.

  • The larger size is generally recommended when foot length falls between standard sizes. Shoes that are slightly too large can be adjusted with insoles or thicker socks. Shoes that are too small can cause discomfort, blisters, and foot problems. The intended use should also be considered—running shoes may benefit from extra space while dress shoes typically fit more precisely.

  • Width is measured across the widest part of the foot, typically at the ball. Standard sizes assume medium width (D for men, B for women). Many brands offer narrow (B/AA for men, AA/AAA for women) and wide (E/EE for men, D/E for women) options. Width affects comfort but does not change length sizing.

  • Children's sizes use a different scale than adult sizes. In the US system, children's sizes run from 0 to 13, then reset to Youth 1-7 before transitioning to adult sizing. Youth size 7 is approximately equivalent to Men's 7 or Women's 8.5. The Kids to Adult Size Calculator provides specific conversions.

  • In the US sizing system, women's sizes run approximately 1.5 sizes higher than men's sizes for the same foot length. A men's size 8 is roughly equivalent to a women's size 9.5. Additionally, women's shoes are typically built on narrower lasts. The Men's to Women's and Women's to Men's calculators provide specific conversions.
