Measuring inner leg length in three steps

But how can you measure your child's inner leg length? Quite simply:

  • Your child stands with its back against a wall wearing shoes.
  • Clamp a book between its legs with the horizontal upper edge at the crotch.
  • Now you can measure the distance from the top edge of the book to the floor with a tape measure or folding rule.

The measured value in centimetres is the inner leg length or crotch height. You can now use it to determine the right size for your child's balance bike or bicycle on our website.
