FORMA FEATURE / EAR & NECKEars: measurements, ratios, and research
Ear height, protrusion, rotation, helix shape, and lobe attachment contribute independently to appearance.
How ears is measured
Ear protrusion is an angle or distance relative to the head, not ear size. A frontal photograph alone cannot reproduce a three-dimensional protrusion angle.
Ratios, ranges & competing claims
≈ 54° in one condition — An ear-protrusion pilot study
Male evaluators began rating one male clone less favorably at protrusion around 54° ± 8.22° in an interactive pilot experiment.
Study: A threshold for a particular clone and evaluator group, not an ideal angle, normal range, or clinical indication. The ideal auricular protrusion—An interactive perceptual pilot study
Practical takeaway
Assess how far the ears stand out, separately from their size.
Use protrusion, rotation, and the upper-to-lower contour to describe their fit with the head. The pilot study below offers a specific preference threshold rather than an ideal size.
What changes the answer
The same protrusion appears more noticeable on a narrower head or with shorter hair. Helix shape and lobe position can make one part project more than another; flattening the entire ear is not a necessary conclusion.
