For the best result, you need a piece of paper, tape to attach it, a pencil, a pair of socks similar to what you would use in your boots/shoes and a ruler. Then follow the guide below.

Put a white piece of paper against the wall on a hard surface. Place your foot so the heel follows the edge of the paper.

Mark the length of you foot, at the longest point, with a pencil and measure both feet as there may be a difference.

Then measure the difference from the bottom of the paper to where you have measured both feet and write down the longest length.

The most precise measurments are when we have measured the boots. When we have done that, it is shown like this.

For childrens boots we don't recommend; as it goes for regular footwear, that you add growth room for up to 1.5 cm, but instead around 0,5 - 1 cm as the size in general needs to fit right away.
