Size Guide Acorn
Summer Hats
We offer the age range below as guidance but head size in children compared with their age can vary quite a lot, so we always recommend if possible to measure the child's head circumference to aid you in selecting the best size. Measure over the forehead and just above the ears using a tape measure or a piece of string and ruler:
