Have a printer?

Download the simple and free to use Size Finder™ Paper Ruler and follow the instructions included with it to measure either your own or your child's foot length from the comfort of your own home.

Don't forget to check your printer settings are marked as "Do not Scale" – otherwise the ruler won't give the right length.

Don't have a printer?

To measure either your own or your child's foot length from the comfort of your own home all you need is a wall and a ruler.

Follow the steps below for each foot and take the largest centimeter size:

• Place the foot on a wooden or hard floor, with the heel touching a wall.
• Stand normally, with equal weight on both feet.
• Place a ruler beside the foot so it is also touching the wall.
• Then take the length in centimeters from the heel to the tip of the longest toe – the longest toe may not be the big toe.

There is no need to add any extra centimeters as we've already calculated growing room into all our measurements.
