Eyes · Front photo

Eye width to height

eye aspect ratio

Higher values mean a longer, narrower eye opening. Smiling or squinting narrows the opening and raises the value.

How it's measured

For each eye: width from inner to outer corner divided by the lid opening, from the upper lid margin to the lower lid margin, measured square to the eye's own corner-to-corner line. Both eyes are averaged and also listed separately.

What changes it

• Typical values differ between populations, so the reference range fits some faces better than others.

One number, one feature

One measurement describes one detail in one photo. Pose, lens and expression move it, and every reference range is an average from limited samples.
