Soulbuddy Hats Size Chart

Tip: If the determined head circumference is between two sizes e.g. 19.3 inches for Kids “Medium” (17.7 - 19.3 inches) and Kids “Large” (19.3 - 21.2 inches) we recommend to choose the larger size.

Every head is different and children’s heads grow rapidly, especially in the first years of life, so the cap size plays an important role. Here you will find all the information about the correct choice of cap, matching the head circumference of the baby or toddler.

You can determine the cap size based on the measured head size or you can orientate yourself by the average head size per age.

Our guide tells you how to measure head size correctly:

Measuring head circumference with the measuring tape

To measure the head circumference (also called hat size) you need a measuring tape.

  • Place the measuring tape about one centimetre above the eyebrows and ears over the forehead (not at the top of the hairline!) horizontally around the child’s head.
  • The tape should be tight but not cut.
  • At the overlap point of the measuring tape, you can read the head circumference directly.

No measuring tape at hand?

Use a cord or thread as a measuring aid and attach it analogously to the measuring tape method. Mark the intersection point and then take the measure, distance from start to mark, with a ruler or meter rod, and then determine the head circumference.
