Lip Ratio
The balance between your upper and lower lip.
| Reference (male) | 1.848 lower lip height ÷ upper lip height |

| Reference (female) | 1.868 lower lip height ÷ upper lip height |
| Weight in composite | 7% |

Proportion, not fullness
Lip ratio compares lower lip height against upper lip height. A lower lip somewhat fuller than the upper is the common reference across most aesthetic guidance; an inverted ratio, with the upper lip fuller, reads as unusual to most observers. The measurement concerns proportion between the two rather than absolute fullness — thin lips in correct proportion score well.
Why straight-line distance corrupts this one
Both heights are measured as pure vertical distances rather than straight-line distances between landmarks. This matters more here than almost anywhere else in the set: the lip landmarks are frequently offset horizontally, and a straight-line measurement inflates both heights unevenly and corrupts the ratio. The references are 1.848 for men and 1.868 for women.
The metric filler moves most directly
Seven per cent of the composite sits here. It is also among the most responsive to non-surgical intervention — filler changes it directly and predictably, more so than most metrics in the set. Note that the score does not reward fuller lips as such; it rewards the correct ratio between them, so over-filling an already-proportionate upper lip lowers the score.
How 123,813 people score on lip ratio
The flattest distribution in the whole set — scores are spread almost evenly across every band, with the bottom band as populated as the top. Very few metrics here separate people this cleanly. Combined with a mid-tier weight and unusual responsiveness to intervention, that makes this a rare place where a deliberate change produces a visible move in the composite rather than a rounding difference.

How to improve your lip ratio
The lower lip should be ~1.618× the height of the upper lip.
Recommendations are grouped by how invasive they are. Non-invasive options change how the feature reads to an observer; surgical options change the underlying structure and therefore the measurement itself.
If you scored Excellent
Your lip proportions are ideal — upper to lower lip ratio matches the golden ratio.
Non-invasive
- Keep lips hydrated with quality balm — your proportions are already ideal
If you scored Good
Your lip ratio is close to golden. Minor emphasis on the right lip can perfect it.
Non-invasive
- Lip gloss on the lower lip emphasizes its volume relative to upper
- Subtle overlining of the underdeveloped lip balances the ratio
If you scored Average
Your lip ratio is moderately off — either upper lip is too prominent or lower lip lacks volume.
Non-invasive
- Lip liner: overline the thinner lip to balance the proportions
- Lighter shade on the lower lip makes it appear fuller
Minimally invasive
- Targeted lip filler to the deficient lip (preserve Cupid's bow)
If you scored Below average
Your lip proportions are significantly off the golden ratio — upper and lower lip are disproportionate.
Non-invasive
- Overlining + color techniques: daily lip correction using liner and gloss
Minimally invasive
- Lip filler: target the deficient lip with 0.5–1ml for ratio correction
Surgical
- Lip lift (subnasal bullhorn) if upper lip height is the issue — shortens philtrum and increases upper lip show
Common questions about lip ratio
Do bigger lips score higher?
No. The metric scores the ratio between upper and lower lip, not absolute size. Proportionate thin lips outscore disproportionate full ones.
What is the ideal lip ratio?
A lower lip roughly 1.85 times the height of the upper — 1.848 for men and 1.868 for women on this landmark set. An upper lip fuller than the lower inverts the ratio and scores poorly.
Will lip filler improve my score?
It can — very little else here responds to a non-surgical change this directly. It can equally lower it: adding volume to an upper lip that was already in proportion pushes the ratio away from the reference.
