HAT SIZE CHART
Always measure head circumference before buying a new hat.
Tip! If you don’t have a measuring tape at home, use a non-stretch string or ribbon and measure the length with a ruler.

How to measure head circumference
- Measure around the widest part of the head, across the forehead and the back of the head. If hair is thick or braided, measure with the hair under the measuring tape.
- Use a flexible measuring tape, keeping it snug but not tight.
- Choose the hat based on the measured result, not on the size of previous hats.
If your child’s head circumference falls between two sizes, we recommend ordering two sizes, keeping the better-fitting one and returning the other.
