FORMA FEATURE / UPPER FACE

Forehead & hairline: measurements, ratios, and research

Forehead height, width, curvature, and hairline shape frame the upper face. Central height alone misses the temporal corners.

How forehead & hairline is measured

Measure central hairline to glabella for height. Evaluate lateral forehead width separately; use a true profile to inspect inclination.

Ratios, ranges & competing claims

Height + lateral shape — Read the whole forehead

A study of 60 celebrities found similar medial forehead height between sexes; larger differences occurred in lateral height, width, and hairline shape. Male hairlines were more horizontal and rose laterally.

Observation: Celebrity selection and photographic measurements describe a sample, not the result of testing every forehead shape. Analysis of Hairline and Forehead Sexual Dimorphic Aesthetics in 60 Celebrities Using Artificial Intelligence

Posterior inclination — Forehead slope

CT-based anatomical research found more posterior forehead inclination in men than women.

Observation: Sex differences do not establish what is most attractive or justify changing frontal bone shape. CT measurement of the frontal sinus—gender differences and implications for frontal cranioplasty

Practical takeaway

Judge the frame, not just forehead height.

Read central height together with the temporal corners, lateral width, and profile slope. A relatively horizontal male hairline with higher corners is a useful descriptive reference.

What changes the answer

The same forehead height looks different with a narrow versus broad face, a recessed hairline, or a prominent brow ridge. Compare the forehead with both remaining facial thirds.
