Czechs nose: bridge, tip and nostril shape in 82 observed portraits

Czechs: bridge profile (sagittal) Mildly convex in 51% of 82; bridge height Medium in 94% of 83; bridge width Medium in 72% of 81; tip shape and definition Bulbous / round in 51% of 82; nostril shape Oval, horizontal in 93% of 82; alar base width Balanced in 56% of 81; nasal length (proportional) Balanced in 77% of 82.

Catalog portraits for Czechs are AI-generated adult subjects; the measurements on this page come from documented photographs of real people, not from these images.

Bridge profile (sagittal)

n = 82 assessable

Shape of the nasal dorsum in the sagittal (side-view) plane. The single most ethnically-variant nasal dimension.

Value	Share	n
Mildly convexSubtle dorsal convexity without a frank hump.	51%	42
StraightLinear dorsum from radix to tip; no convex or concave deviation.	46%	38
Convex / aquiline (Roman)Pronounced dorsal hump; the dorsum is convex above the tip. Common in Mediterranean, Middle Eastern, and some indigenous American populations.	2%	2

Vocabulary: Bridge profile (sagittal) (rhinoplasty_dorsal_profile)

Bridge height

n = 83 assessable

Vertical projection of the nasal dorsum from the facial plane. A primary axis of ethnic variation independent of bridge profile shape.

Value	Share	n
MediumAverage dorsal projection.	94%	78
Prominent / high-setMarked dorsal projection. Common in European, Mediterranean, Middle Eastern, and some indigenous American populations.	6%	5

Vocabulary: Bridge height (nasal_dorsum_height_qualitative)

Bridge width

n = 81 assessable

Width of the nasal dorsum at the mid-dorsum point, relative to the intercanthal distance.

Value	Share	n
NarrowMid-dorsum width less than approximately 60% of intercanthal distance.	14%	11
MediumMid-dorsum width approximately 60-80% of intercanthal distance.	72%	58
WideMid-dorsum width approximately equal to or exceeding intercanthal distance.	15%	12

Vocabulary: Bridge width (nasal_dorsum_width_qualitative)

Tip shape and definition

n = 82 assessable

Morphology and definition of the nasal tip — encompassing both shape (the silhouette) and definition (visibility of the lower lateral cartilage anatomy).

Value	Share	n
Bulbous / roundWide, fleshy, rounded tip with little visible cartilage definition.	51%	42
Defined / refinedTip has clear definition with visible tip-defining points but is not pointed; smooth supratip break.	44%	36
Hooked / droopingTip projects downward with a hook at the apex; columella sits below the alar base.	5%	4

Vocabulary: Tip shape and definition (rohrich_tip_morphology)

Nostril shape

n = 82 assessable

Shape of the nostril aperture as visible from inferior view. Significant ethnic variation — round vs oval predominantly maps to West African vs European populations.

Value	Share	n
Oval, horizontalLong axis of nostril roughly parallel to the alar base; common in some Sub-Saharan African populations.	93%	76
Oval, verticalLong axis approximately perpendicular to alar base; common in European populations.	7%	6

Vocabulary: Nostril shape (farkas_nostril_typology)

Alar base width

n = 81 assessable

Width of the nasal base measured between the most lateral points of the alae. The aesthetic reference is alar base width approximately equal to intercanthal distance, but this norm is European-derived and does not apply across all populations.

Value	Share	n
NarrowAlar base width substantially less than intercanthal distance.	9%	7
BalancedAlar base width approximately equal to intercanthal distance.	56%	45
WideAlar base width substantially greater than intercanthal distance. Common in Sub-Saharan African and some indigenous populations; the European-norm-derived aesthetic descriptor 'wide' should not be read as deviation from a universal ideal.	36%	29

Vocabulary: Alar base width (ferreras_garcia_alar_base_qualitative)

Nasal length (proportional)

n = 82 assessable

Length of the nose from radix (nasion) to subnasale, expressed proportionally relative to the lower facial third.

Value	Share	n
BalancedNasal length approximately 90-110% of lower facial third (Farkas aesthetic reference).	77%	63
LongNasal length greater than ~110% of lower facial third.	23%	19

Vocabulary: Nasal length (proportional) (facial_thirds_proportion)

Where these numbers come from

83 publicly documented portraits of notable Czechs 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.
