Welsh lips: volume, shape and philtrum in 71 observed portraits
Welsh: overall lip volume Moderate in 86% of 71; upper-to-lower lip volume ratio Balanced (~1:1) in 100% of 70; cupid's bow morphology Soft / rounded in 99% of 70; philtrum definition Defined columns in 46% of 71; mouth width Balanced in 68% of 71.
Catalog portraits for Welsh are AI-generated adult subjects; the measurements on this page come from documented photographs of real people, not from these images.
Overall lip volume
n = 71 assessableCombined lip volume from a frontal view. Independent ethnic-correlated dimension; West African and African-diaspora populations average higher native lip volume than European populations, with substantial individual variation.
| Value | Share | n | |
|---|---|---|---|
| ThinMinimal lip volume; lips barely project from the perioral plane. | 8% | 6 | |
| ModerateAverage volume; lips clearly visible with modest projection. | 86% | 61 | |
| FullPronounced volume; lips project substantially from the perioral plane. | 6% | 4 |
Vocabulary: Overall lip volume (lip_volume_qualitative)
Upper-to-lower lip volume ratio
n = 70 assessableRelative volume of the upper lip compared to the lower lip in frontal view.
| Value | Share | n | |
|---|---|---|---|
| Balanced (~1:1)Upper and lower lip of approximately equal volume. | 100% | 70 |
Vocabulary: Upper-to-lower lip volume ratio (mallucci_branford_lip_ratio)
Cupid's bow morphology
n = 70 assessableShape of the upper-lip vermilion border at midline (Cupid's bow).
| Value | Share | n | |
|---|---|---|---|
| Soft / roundedGentle curves at the peaks; M-shape present but rounded. | 99% | 69 | |
| Sharp / definedCrisp angular peaks at the philtral columns; clear M-shape. | 1% | 1 |
Vocabulary: Cupid's bow morphology (cupids_bow_qualitative)
Philtrum definition
n = 71 assessableShape and definition of the philtrum (the vertical groove between the nose and upper lip).
| Value | Share | n | |
|---|---|---|---|
| Defined columnsClear philtral columns visible; well-demarcated central groove. | 46% | 33 | |
| SoftSubtle column definition. | 45% | 32 | |
| Elongated (long upper lip)Vertical philtrum length above the aesthetic reference range. | 4% | 3 | |
| Smooth / minimalPhiltrum nearly flat; columns not distinct. | 4% | 3 |
Vocabulary: Philtrum definition (philtrum_qualitative)
Mouth width
n = 71 assessableWidth of the mouth (cheilion to cheilion) relative to the inter-iris distance.
| Value | Share | n | |
|---|---|---|---|
| BalancedMouth width approximately equal to inter-iris distance (Farkas reference). | 68% | 48 | |
| WideMouth width substantially greater than inter-iris distance. | 32% | 23 |
Vocabulary: Mouth width (mouth_width_proportional)
Where these numbers come from
71 publicly documented portraits of notable Welsh people were assessed by a vision model against the full 22-vocabulary schema, one value per dimension. Values are what the photographs show, read by a model, not population measurements. Each table counts only portraits where the value could be assessed; covered, obscured and unclear portraits are reported separately.
Notable-people corpora skew older, so hair color over-represents gray and white, and image quality varies. Treat shares as a description of this sample.
These rows are not yet in the published catalog dataset, which currently carries the earlier single-row analysis; see the methodology. A family page exists only when at least 10 portraits carry an assessable value.
