How to Measure Your Head

  1. Grab a soft measuring tape or a piece of string (like twine or a shoelace) and a ruler or measuring tool
  2. Wrap a soft tape or string around your head to measure about 1/4 to 1/2 inch above your ear and about 3/4 to an 1" inch above your brow line (see image)
    • Mark the tape or your string, where it intersects, with your finger.
  3. Record your measurement in inches or centimeters (centimeters is often more accurate)
    • If you're using a string, run it along side the ruler as many times as necessary to get a complete measurement
  4. MEASURE AGAIN!
    • Always measure more than once until you get the same number twice
  5. Find your size in the chart for the perfect fit
