How to size children's hats
Choose the right size hat for your child. (child & hat image by Katrina Miller from

An ear infection in children under the age of 2 is a common reason for why children visit a paediatrician. When children get ear infections, it also deprives frustrated parents of much needed sleep. Teaching children to wear a hat is one way to help protect them from harsh elements. Choosing the right size hat for your child will ensure that she will want to wear the hat to protect her head, eyes, and ears from the sun, wind and cold so everyone can get a good night's rest.

  1. 1

    Determine your child's head circumference by measuring your child's head with a tape measure to establish what size hat your child will wear.

  2. 2

    Place the end of the tape measure with the smallest number in the middle of your child's forehead.

  3. 3

    Wrap the tape measure all the way around your child's head, holding the tape measure just above your child's eyebrows.

  4. 4

    Place your index finger between the child's head and the tape measure to ensure the measurement includes a little extra room.

  5. 5

    Read the measurement from the beginning of the tape measure to where the tape measure meets at the centre of your child's forehead. Record that number with your marker.

  6. 6

    Refer to the following chart to determine what size hat your child will wear.

    Head circumference:

    14 inches to 15 inches = 0 to 3 months old = Child's X small 15 inches to 17 inches = 3 to 6 months old = Child's Small 17 inches to 18.5 inches = 6 to 12 months old = Child's Small 19.5 inches to 20.75 inches = 1 to 2 years old = Child's Medium 20.75 inches to 21.25 inches = 2 to 4 years old = Child's Large 21.5 inches to 22 inches = 4 to 8 years old = Child's X Large

Tips and warnings

  • It is better for your child to wear a hat that is a little too big than one that is too small.
  • Hat size is based on head circumference rather than on the child's age.
