Brow Length to Face Width Ratio

The combined horizontal spans of both brows divided by cheekbone width.

What is measured

The calculation

(Left brow span + right brow span) ÷ cheekbone width

Schematic illustration, not to scale. Lines show the measurement construction; this is not an ideal face or a scored result.

Why it matters

Brows frame a share of the face’s total width. This distinguishes short brows on a broad face from longer brows that extend further across the upper face.

  • Lower: shorter combined brow spans relative to the face.
  • Higher: longer combined brow spans relative to the face.

Where the idea comes from

FaceIQ adaptation

Comparing widths belongs to the anthropometric tradition. FaceIQ expresses these photographed distances as a ratio; population measurements provide context rather than proof of this particular scoring range. [1] [2]

A worked example

Two brows each spanning 49 units across a 140-unit face give (49 + 49) ÷ 140 = 0.70.

Example values explain the calculation. They are not a target range and are not measurements of the schematic above.

Research & further reading

The sources below explain the history or related evidence. FaceIQ’s score weights and reference ranges are model settings; these papers do not collectively validate the scoring system.

    A contemporary assessment of facial aesthetic preferences

    Compared ratings of edited brow and nose features on four female models. The authors emphasized individual facial harmony; this is context for feature relationships, not a test of every brow metric.

    International anthropometric study of facial morphology in various ethnic groups/races

    Documents variation in facial dimensions across sampled populations. Descriptive measurements explain variation; they do not establish an attractiveness score.
