Brow peak position ratio

Brow peak position expresses the distance from the inner brow to its peak as a percentage of the full brow width. At 66.6%, the peak sits about two-thirds of the way toward the tail.

Brow peak position ratio

inner-brow-to-peak width as a percentage of full brow width, averaged across both sides.

The lines mark brow peak position ratio.

What different proportions look like

Compare lower and higher values with the original portrait in the centre.

Same model, lower and higher values

The peak sits slightly farther outward in the right example than in the original portrait.

Brow shape

An inward peak shortens the rising inner section and leaves a longer descending tail. A peak farther outward gives the brow a longer inner run with a shorter tail.

The surrounding eye region

This percentage describes peak location, rather than arch height or sharpness. A flat brow can peak at two-thirds, as can a sharply arched brow. On a nearly flat brow, the highest point may be difficult to distinguish.

Male-model reference and app range

The male-model study describes the apex at roughly two-thirds of brow width from the inner end. The 61.6–71.6% reference interval is a comparison range chosen by Glowometry, not a measured spread from the study.

The study describes a selected group of male models, rather than testing which value maximises attractiveness.

Measurement endpoints

Measure the horizontal distance from the inner brow to its highest point. Divide it by the full horizontal brow width and multiply by 100.

Reading your result

The app reference is 61.6–71.6%. Below it: The peak sits closer to the inner brow. Above it: The peak sits closer to the outer tail.

Inspect both sides as well as the average. A similar combined value can come from matching brows or from different left and right measurements.

How we measure it

Where the highest point of the brow falls along its full horizontal length.

1
Measure the horizontal distance from the inner brow to its highest point. Divide it by the full horizontal brow width and multiply by 100.
2
Measure both brows separately, then average the results. Millimetre values are estimates from the photograph.

Getting a clear photograph

Raising or frowning the brows moves their contours. Keep the forehead relaxed.
Face the camera directly with naturally open eyes. Head turn can distort brow width and height.
Grooming, sparse tails and shadows can make the brow edge difficult to see.

Check the marked points

Check that inner endpoints and tails sit on the intended visible brow borders.
Check the upper contour and selected peak where the guide uses them.
Confirm that the pupil centres are placed consistently, then inspect each side’s lines.
