How To Measure Your PD

How to Measure Your Pupillary Distance (PD)

Pupillary Distance (PD) is the distance between the centers of your pupils. It helps us position your lenses correctly in your frames for clear, comfortable vision.

Don’t know your PD? No worries! Just follow these easy steps:

  1. 📥 Download and print our PD Ruler at 100% scale – do not scale or fit to page.
  2. ✂️ Cut out the ruler and stand in front of a mirror, or ask a friend to help.
  3. 👁️ Hold the ruler flat just above your eyes. Line up the zero (0) mark with the center of your right pupil.
  4. 🔍 Read the measurement at the center of your left pupil. That’s your PD!
