The distance between the two eyes.
Biocular
How to measure
Application
Used in eyewear, goggle, virtual reality headset, and face mask design to determine the required horizontal span between lenses or eye openings.
Posture
Head level, looking straight ahead.
Landmark
Measured between the outer corners of the two eyes (outer canthi), not the pupils or inner corners.
Tool
Digital caliper or rigid ruler.
Common mistake
Measuring between the inner corners (inner canthi) gives intercanthal width — a narrower and different measurement used for a different purpose.
