FORMA FEATURE / UPPER FACEEyebrows: measurements, ratios, and research
Brow thickness, length, arch, and distance above the eyes affect the expression of the entire upper face.
How eyebrows is measured
Separate hair thickness from brow-bone projection. Brow-to-eye distance needs a relaxed expression; raising the eyebrows changes it immediately.
Ratios, ranges & competing claims
Practical takeaway
Favor a coherent eye frame over simply higher brows.
Thickness, shape, and relaxed brow-to-eye spacing are the useful variables. The studies below make a stronger case for paying attention to brow framing than for lifting the brow as high as possible.
What changes the answer
Upper-lid exposure, orbital depth, natural arch, and hair density change how close or heavy the brows appear. Measure at rest so expression does not set the target.
