UK Size Conversion Table

The easiest way to search for shoes on our website is by size. We have created a handy conversion table which will allow you to convert the centimtetre (cm) measurement of your child’s foot into the recommended UK shoe size. You can then use this UK size to search for shoes on our website.

The conversion is based on taking the actual foot measurement and adding approximately 0.8cm for growing room. For example if your child's feet measure 12.2cm using the conversion table below you need to search for shoes in a UK4. This will then provide you with a selection of shoes in stock with an internal length of approximately 13cm. Please read our step-by-step sizing guide on how to adjust this size for different styles and widths.

If you have used our measuring device to measure the length of your child's foot, please make sure you use the actual foot measurement when using this table. To get the actual foot length you need to use the measurement taken from the white bar as shown below. The shoes you buy should then correspond to the measurement indicated by the arrow in the window which includes an allowance for growing room.
