Children UK Size. Measurements Converter

Although not well known and not widely used this is the official international standard for shoe sizes ISO 9407:1991. It is based on the mean foot length and width measured in millimeters. This standard is used by NATO and some other military systems as it allows better fitting. Sky boots are often marked with mondopoint too. Mondopoint shoe size of 250/100 means length 250mm and width 100mm.

There are different systems of shoe sizes that are used in the United States at the same time. A customary traditional system is based on the English sizes but starts at one instead of zero so U.S. sizes are one greater than British. This system is based on the length of the shoe last (foot-shaped template for manufacturing shoes). Measuring the last instead of a foot is easier for shoe manufactures but makes it harded for the consumers. The inner cavity of the shoe must usually be 2/3 inch longer than the foot length. In this converter we add 2/3 inch when converting from last-based to foot-based sizes. There is also a less popular Footwear industries of America (FIA) scale also known as "standard". It measures female sizes slightly different.

European scale is based on the last length expressed in Paris points (2/3 cm). The scale is the same for both genders and for adults and children.

The official standards GOST 23251-83, GOST 11373-88 declare the shoe size to be measured by the length of a foot expressed in millimeters. However in practice shoes are marked either with traditional system based on a foot length expressed in Paris points or with foot length measured in centimeters. The scale is the same for both genders and for adults and children.

The UK scale is based on the length of the last measured in barleycorns starting with zero for the smallest practical size. The scale is not formally standardized. The child's size 0 has a length of a hand, the biggest child's size is 13.5. The adult size 1 is one barleycorn longer than the biggest child's size. The scale is the same for male and female. Please note though some shoe manufactures in the UK use slightly different scales. For example a shoe of UK size 6 made be Jimmy Choo might be the same size with a shoe of size 7.5 made by Crocs.

Asian system is based on a foot length expressed in centimeters. It is officially standardized in many countries, e.g. Japan, China and Korea.

Hong Kong uses European shoe scale

In Mexico shoes are marked either in another version of barleycorn-based system by last length, or by a foot length in centimeters or inches.

Female shoes are usually sold in U.S. sizes while children and male shoes use the UK scale

In Brazil the scale similar to European is used with the only difference Brazilian size being smaller by 2.
