How to Measure Your Head Size

Follow these simple steps to measure your head accurately:

  1. Use a Flexible Measuring Tape: If you don’t have one, use a string and measure it with a ruler afterward.
  2. Wrap Around the Widest Part: Measure just above your eyebrows and ears, where a hat naturally sits.
  3. Record the Measurement: Note the size in inches or centimeters for easy reference.
