How to measure my pupillary distance (PD)

What you’ll need:

  • Mirror
  • Ruler marked in millimeters

Step 1: Stand about 8” away from the mirror. Align the ruler’s 0mm with the center of your right pupil.

Step 2: Looking straight ahead, measure the distance between the center of your right pupil and the center of your left pupil. Hold the ruler against your brows for extra stability.

Step 3: Measure again to make sure you got it right first time. Same numbers? You’ve found your PD! (Fun fact: Adults generally have a PD range between 54-74mm.)
