Brow length
Brow length measures how far the eyebrow extends across the eye region. Longer brows frame more of the outer eye and temple; shorter brows end closer to the eye opening. The app averages the horizontal width of both brows.

Brow shape
A longer span carries the brow farther toward the temple and strengthens its horizontal frame. A shorter span leaves more space beyond the brow tail. A long, sparse tail can look shorter than a dense one with the same measured width.
The surrounding eye region
Read length alongside eye width and peak position. A broad brow can frame a long eye well, while the same span over a shorter eye extends farther beyond its corners. Moving the tail also changes the fraction of the brow occupied by the inner section, even if the peak stays fixed.
Male-model reference and app range
In 300 White professional male models, Pietruski and Majak reported a horizontal brow width of 47.28 ± 4.55 mm. The app uses 42.7–51.8 mm as its reference band, rounded from the mean minus and plus one standard deviation.
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 edge of each brow to its tail, rather than following the curve of the hairs.
Reading your result
The app reference is 42.7–51.8 mm. Below it: A shorter horizontal brow span. Above it: A longer horizontal brow span.
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
The full horizontal span of each eyebrow, from its inner edge to its tail.
- 1
Measure the horizontal distance from the inner edge of each brow to its tail, rather than following the curve of the hairs.
- 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.
