Hat Sizing

Babies (and heads in particular) grow at such different rates, and can be such a variety of sizes, we do not put an age in our sun hat.  The ages on the page are a rough guide only.

We know the circumference of each hat size – and using the chart below you can determine which size is for you:

Hat Size


Guide age range
Small            45 6-12 mts
Medium           47.5 1-2y
Large           50 2-3y
XL          53 3-4y
