The sizes are chosen by the measurement of the upper arm, just under the armpit and around the bicep, or by the desired size of bag for your child.
To measure: Take a tape measure and wrap it around the largest part of your child's upper arm, around the area of the bicep or just under the armpit. Take that number and choose from our 3 great sizes. Our sizes are made to work up to the size we have listed for the most comfort and usage. If your child's arms are smaller than the measurement listed, it is not a problem! The Lindy-Lu bag works just the same with a little extra space!
