How to Use this Shoe Size Converter

The calculator is quite easy to use, here is what you need to do:

Select the age group as either adult or child
Specify the shoe size system you want to convert from
Select (or input) the original shoe size
Specify the target shoe system
Press the ‘Calculate’ button to get the new size

Please keep in mind that the calculation result will be ‘NA’ if there is no equivalent shoe size available in the target system.

The Included Shoe Size Systems

The calculator will allow you to convert between the shoe sizes for US, UK, Europe, Japan/Mexico, China, Korea and Russia.

We also added the option to use the foot length in centimeters or inches if it’s needed.

Please note there is a size difference between men and women in each of the US and UK. Men’s shoe size is generally bigger than the women’s size by one.

It’s also worth mentioning that Japan/Mexico, Korea, Russia and China are all part of the Mondopoint shoe system. This system is based on average foot length (and optional foot width) for which the shoe is suitable, measured in millimeters or centimeters.

In case you wonder where in the world each system is used, here is a summary:

Shoe Size System	Countries
United Kingdom	United Kingdom, Ireland, India, Pakistan, South Africa in addition to Australia and New Zealand (for men/kids only)
United States	United States, Canada in addition to Australia and New Zealand (for women only)
Continental Europe	Austria, Belgium, Denmark, France, Germany, Italy, Luxembourg, the Netherlands, Norway, Poland, Portugal, Spain, Sweden, Switzerland, most other continental European countries, Middle Eastern countries, Hong Kong and Brazil (modified)
Mondopoint	Russia, China, Japan, Taiwan, South Korea and Mexico

How the Shoe Size Converter Works

The calculator above uses shoe formulas for converting the shoe size for the US, UK, Europe and China systems. For Russia, a size chart is used instead.

Here are the formulas for shoe sizes based on the foot length in inches (IN) or centimeters (CM):

US_male = (3 x IN) – 22
US_female = (3 x IN) – 21
US_child = (3 x IN) – 9.75
UK_male = (3 x IN) – 23
UK_female = (3 x IN) – 24
UK_child = (3 x IN) – 10.75
Europe_size = (3/2) x CM + 2
China_size = 2 x ceiling(CM,0.5) – 10

Here is the size chart used for Russia:

Shoe Size (Russia)	Foot Length
Shoe Size (Russia)	(cm)	(in)
16	9.5	3.7
