Understanding UK Shoe Sizes

The UK standard is considered to be the oldest used shoe sizing metric in the world, dating back to as early as 1324 when it was made the standard English shoe measurement by King Edward II.

The British shoe size standard is based on the measurement of the ‘shoe last’ which is typically made of wood, but could also be from other materials. This shoe frame measures 13 to 17 mm more than the natural shoe size from heel to toe.

Under the UK standard, there is distinction between adult and children’s shoe sizes. Men and women also have specified measurements. This is different than the Paris point-based system which has a uniform standard for children and adults shoes.

The UK shoe size standard only considers the length of the foot, but not the width. Shoes then tend to have different width measurements depending on the ‘shoe last’ used by the brand.
Each size in UK shoe sizing has a 8.46 mm (or one-third of an inch) difference. The half-sizes (4.23 mm) difference were per pair were introduced in 1880 to ensure better fit.
Generally, the UK’s shoes sizing standard is also used in Australia. Other countries such as the US, China, Japan, and even other European country like France also uses their own shoe size standard.
