The literature on art history and the aesthetics of photography puts forward a theory of dividing the canvas into thirds, horizontally and vertically. And when human faces are portrayed, two concrete rules for the position of the eyeline are often mentioned:
- the rule of thirds: the eyeline should be 2/3 (≈0.67) from the bottom
- the golden ratio rule: the eyeline should be at 1/(golden ratio) (≈0.62) from the bottom
The maxima of the eyeline height distribution for photographs and paintings is predominately in the range of 0.6 to 0.67.
