Why is a longer EyeBrow length better than shorter one

In a study for the Aesthetic Surgery Journal (Schreiber et al, 2005), these doctors compared modern-day eyebrow photos ranked by attractiveness to the traditional ‘Westmore eyebrow’ model and created a newer, and improved, guideline for the ideal eyebrow placement and length. This new model bases the ideal eyebrow length around other features of the facial anatomy. The distance from the medial canthus to the medial eyebrow should occur at a mean ratio of 0.573 to the eye’s length. The end of the brow should fall at a ratio of 0.688 (of the eye’s length) to the space between the lateral limbus and lateral eyebrow end. As the eyebrow is often likened to a ‘frame’ for the eye throughout the literature, it makes sense that eyebrow length and eye length might influence each other's ideal morphology.

Across scientific literature there are many documented advantages to having a longer female eyebrow: it can make “one seem more trustworthy”, “be perceived as more attractive” (Kleisner et al, 2013) and “make the eyes look larger” (Zhao et al, 2019).
