A bar chart of average IPD in humans

IPD (interpupillary distance) is the distance between the pupils of the eyes.

Most adult humans have an IPD of about 63mm.

IPD can be measured in a number of ways.

Some VR headsets have an IPD adjustment. The Oculus Rift DK1, DK2, and HTC Vive have manual IPD adjustment. And the Valve index too.

Mirror measurement[edit]

IPD can be measured using a mirror.

It can be measured by standing close to a vertical mirror, and close one eye at a time. Each eye look directly into that eye on the mirror, use a marker to mark a spot on the mirror where the pupil is. The distance between the dots is a measurement of IPD.[1]
