The width of the lips should be about 40% of the width of the lower face and generally equal to the distance between the medial limbi. The width-to-height ratio of the face is typically 3:4, with an oval-shaped face being the aesthetic ideal.
Based on their results, a pair of “average lips” has measurements of 7.8mm for the upper lip at the midline and 12.2mm for the lower lip. This gives an upper to lower lip ratio of 1:1.56.
In the subjective assessments, a lip proportion of 1 to 1.6 (upper lip to lower lip) was rated as most attractive: average score of 4.21 out of a possible 5. The 1:1.6 proportion is widely accepted as the "golden ratio" for beautiful lips.
Well, quite a lot, as it turns out that full and sumptuous lips are the most preferable lip shape of them all — but according to a global study, there's one key trait that distinguishes the perfect pouts from their equally plump, yet sub-par, counterparts.
The Golden Ratio
If we follow the Phi Ratio of Beauty, otherwise known as the “Golden Ratio” of 1.618, the perfect lips would be 1.618 times larger than the top lip and 1.618 times wider than the width of the nose.

The study polled over 1,000 people in 35 countries. Of those polled, 60% said they found a symmetrical, 1:1 top to bottom ratio the most attractive lip (think Scarlett Johansson). The next highest-rated, according to the poll, was a larger bottom lip compared to the top lip (like those rocked by Kylie Jenner).
Lips come in a variety of shapes characterized by the upper lip to lower lip ratio. A 2017 study from JAMA Facial Plastic Surgery showed the most attractive ratio is 1:2 of upper and lower lip. An increase in surface area of 53.5 percent was also deemed most attractive.
It turned out that the picture on the far-left marked 'A' was actually seen as most attractive. Unsurprisingly to anyone with functioning eye balls, 'D', with a heavy upper lip, was the least attractive look. In fact, it was the heavier lower lip that was rated most attractive.
