How Do I Measure My Face?

  1. Measure Face Width:
    Use a hard ruler to measure from the outer corner of your eye on one side to the outer corner of your other eye.
  2. Measure Face Height:
    Measure from just below your nose up to just above your eyebrow line.
  3. Compare Your Measurements:
    Match your width and height measurements with our mask specifications below. Aim to be between Min and Max, and as close to Optimal as possible.
