Interbrow : eye width

What interbrow spacing measures

Interbrow spacing is the gap between the heads (the inner ends) of your two eyebrows, measured relative to the width of one eye. The glabella, the smooth pad of bone and skin between the brows and just above the bridge of the nose, occupies this gap. Expressed as a ratio, a value near 1.0 means the brow heads sit about one eye-width apart.

As with the other brow metrics, the point being measured is hair rather than bone, so where the brows are plucked and where they naturally grow set this figure as much as the underlying structure does.

Why it matters

The inter-brow gap frames the centre of the upper face and helps anchor the nose and eyes. When the gap is very narrow the brows crowd toward the midline and, at the extreme, can meet, the look colloquially called a monobrow, which tends to read as heavy or intense. When the gap is wide the brows look far apart or sparse, weakening the frame around the eyes. A moderate gap keeps the brows reading as two clean, distinct frames. The width of the gap also interacts with how broad the nose looks beneath it, since the eye reads the central column of the face as a whole. The glabella is also where vertical frown lines form, so the area between the brows carries a fair amount of expressive weight.

The conventional range and its caveats

The convention, drawn from Farkas 1994's anthropometric work, is that the brow heads sit about one eye-width apart. On this app's mesh the figure reads slightly wide, so the scored band runs from about 1.0 to 1.15 eye-widths, with the modelled average near 1.10.

This is a neoclassical-style proportion, and such canons are conventions rather than objective rules: anthropometric surveys, including Farkas's own, have documented how much real faces vary around these 'ideal' proportions across populations and individuals. Because brow position is also one of the easiest features to change by grooming, this number describes current brow styling at least as much as it describes fixed anatomy.

Reading and changing your own value

A value inside the band means your brows frame the central face with a balanced gap. A low value points to closely set brow heads; it is worth checking whether stray hairs across the glabella are pulling the measurement inward. A high value points to a wide gap, where filling the inner heads slightly can strengthen the frame.

This metric is almost entirely groomable. Tweezing or waxing the inner ends widens the gap; letting the heads grow in, or filling them with a pencil or powder, narrows it. Because the bone of the glabella barely constrains where brow hair grows, there is very little here that is fixed; it is one of the most directly adjustable items in the whole report, and is best treated as a styling decision rather than a verdict on your structure.
