Nose Shapes and Ethnicity: How Nose Types Vary by Ancestry
Short answer: sort of. On average, people whose ancestors came from different parts of the world have slightly different noses, and nostril width shows the clearest pattern. But groups overlap a lot, so a nose can't tell you someone's ethnicity.
This guide covers what researchers actually found, where your nose shape comes from, and why "ethnic nose types" is a much blurrier idea than most charts make it look. It's part of our guide to ethnicity.

Do Nose Shapes Differ by Ethnicity?
Yes, on average. People whose ancestors came from different regions tend to differ a bit in nose shape, mostly in nostril width. But those are averages, not rules: noses vary a lot inside every ethnic group, and a big review of nose research found that nose size and shape don't define racial groups.
The main study, in plain terms:
Who: people with West African, South Asian, East Asian or Northern European ancestry
How: 3D face scans measuring things like nostril width, nose height and how far the nose sticks out
Result: two traits stood out, nostril width and the width of the nose base. The gaps between groups were bigger than random chance explains (2017 study in PLOS Genetics)
What this doesn't mean:
"Ethnic nose type" isn't a real scientific category. Sorting people into races by nose shape goes back to 19th and early 20th century anthropology, and modern reviews don't back it up.
An average says nothing about you. Two people with the same ancestry can have very different noses.
Ethnicity vs. Ancestry: Why "Ethnic Nose Shapes" Is a Loose Term
Ethnicity is about culture, language and identity. Ancestry is about where your ancestors lived and the DNA you got from them. Your nose follows ancestry, not the ethnic label on a form. NHGRI says there is more genetic variation inside self-identified racial groups than between them.
Why the label doesn't match the genes:
Big US study: researchers looked at 230,016 genomes from the All of Us program. People in the same race or ethnicity group showed a spread of ancestry, not one clean profile (2025 study in the American Journal of Human Genetics).
"Latino" is a good example: in a 2016 study of about 6,000 Latin Americans, average estimated ancestry came out at roughly 50% European, 45% Native American and 5% African. That's a mix, not one nose type.
Mixed ancestry is everywhere: your nose reflects the mix you inherited, not one category.
How Nose Shape Is Described: Bridge, Nostrils, Tip
Nose shape comes down to a few traits: bridge height and contour, nostril width, tip shape, how far the nose projects, and the angle between the nose and upper lip. Two people can share a bridge shape and still have totally different nostrils or tips, so one-word labels only describe part of a nose.
The traits people look at:
Bridge: how high, how broad, and whether the profile is straight, curved or dipped
Nostrils and nose wings: how wide the nose is at the base
Tip: pointed or rounded, tilted up or down
Projection: how far the nose sticks out from the face
Nose-to-lip angle: where the tip points relative to the upper lip
Names like Roman or button describe the bridge or the tip, not a whole nose. For the common shapes by name, see our guide to 12 nose shapes.
Nose Shapes by Ethnicity: What Studies Actually Measured
Researchers have measured specific nose traits, not "ethnic noses." The clearest pattern between populations is in nostril width and nose base width. Bridge breadth and tip tilt have been tied to specific genes, but those studies don't give a profile for any named ethnic group.
Trait | What studies found | Keep in mind |
|---|---|---|
Nostril width | Differs between ancestry groups more than chance explains. Wider in ancestors from warm, humid regions, narrower from cold, dry ones (2017 study) | The authors call climate a simplified explanation |
Nose base width | Same pattern as nostril width (2017 study) | Only four ancestry groups were measured |
Nose bridge breadth | Linked to the RUNX2 gene region in about 6,000 Latin Americans (2016 study) | About genes, not ethnic groups |
Tip tilt | Linked to the DCHS2 gene region in the same study (2016 study) | About genes, not ethnic groups |
Nose Types Chart by Ethnicity: Why This Page Uses Traits, Not Labels
You'll find charts that match each ethnicity to a nose type. This page doesn't have one. A review of nose measurements found that the numbers for racial groups overlap heavily and rest on categories with no scientific basis, which makes them of little use even for planning nose surgery. A chart built on that would look precise and tell you very little about your nose.
Where Ethnic Nose Shapes Come From: Climate and Genes
Nose shape is inherited through genes, and climate may explain part of the differences between populations. The nose warms and humidifies the air you breathe, so narrower nostrils may have helped in cold, dry regions. Researchers link wider nostrils to warm, humid ancestral climates, but call this only part of the story.
Climate
Nostril width matched the temperature and the amount of moisture in the air in ancestral regions (2017 study).
The authors say other forces, like what people found attractive over time, may also have shaped the nose.
One of the authors has also said that a lot of nose variation between populations comes down to random chance in how genes spread, called genetic drift (press release).
Genes
Different nose traits are tied to different genes. In a 2016 study of about 6,000 Latin Americans, nose bridge breadth was linked to RUNX2, tip tilt to DCHS2, and nostril width to GLI3 and PAX1.
The same paper cites earlier studies that estimated facial features to be about 60–90% heritable. That means genes account for most of the differences between people in how faces look, though it is a figure for facial features in general, not for any one nose. Each gene variant found in the study explained only about 1% of the variation in its trait.
So your nose comes from the specific combination of genes you inherited. Where your ancestors lived shaped the odds, not your outcome.
Roman, Button and Other Named Noses: Do They Belong to One Ethnicity?
No. Roman and button are names for the shape of a nose, not for an ethnic group. Roman describes the bridge profile, button usually describes a small, rounded tip. No study used on this page ties either shape to a single ethnicity.
Roman Nose and Ethnicity
A Roman nose is defined by a convex bridge that arches outward, sometimes with a bump, not by where someone's family is from. For what it looks like, how it differs from a Greek nose and what is known about its genetics, see our Roman nose guide.
Button Nose and Ethnicity
A button nose is usually described as small with a softly rounded tip, again a shape and not a group. Sources define it a little differently. Our button nose guide covers what it looks like, how it differs from a snub nose, how it changes with age and whether it can be changed.
Can You Tell Someone's Ethnicity From Their Nose?
No. Group averages exist, but the overlap between groups is huge, and ethnicity is a cultural label, not a genetic one. A review of nasal research found that nose size and shape don't define racial groups, so no single nose can reliably point to a person's ethnicity or ancestry.
Ancestry and nose shape are linked only as population averages. In the 2016 study of Latin Americans, several facial traits showed just moderate correlations with genetic ancestry (Nature Communications). That describes a tendency across a population, not a rule you can apply to one person's nose.
Why a nose can't give it away:
Overlap: there is more genetic variation inside racial groups than between them (NHGRI).
Gradients, not boxes: in the All of Us data, people in the same race or ethnicity group show a spread of ancestry, not one profile (American Journal of Human Genetics, 2025).
One feature among many: even where a trait like nostril width differs on average, it says little about a single person (2009 review).
Labels aren't biology: NHGRI describes race as a social construct that changes over time, place and context.
Mixed Ancestry and Nose Shape
If your family has roots in more than one region, your nose can mix traits in ways no chart predicts. Bridge breadth, tip tilt and nostril width are tied to different genes, so they can come from different ancestors (2016 study).
FAQ
Can you tell ethnicity by nose shape?
No. Nose shape differs on average between populations, but the overlap is large and ethnicity is a cultural label. A big review found that nose size and shape don't define racial groups (2009 review).
What does your nose say about your ancestry?
Not much about any one person. Average nose traits such as nostril width differ between populations, but the overlap is large, so ancestry can't be read from a nose shape (2009 review).
Which ethnicity has a Roman nose?
None in particular. A Roman nose is a bridge shape, and people of any ancestry can have it. Averages for some nose traits differ between populations, but the overlap between groups is large (2010 review).
Does climate affect nose shape?
Possibly, over many generations. Nostril width in ancestral populations matched temperature and the amount of moisture in the air, though the authors call climate a simplified explanation (2017 study).
Is nose shape genetic?
Largely, yes. Studies have linked specific gene regions to bridge breadth, tip tilt and nostril width, and genes are estimated to explain about 60–90% of the differences in facial features (estimate cited in a 2016 study).
Do you inherit your nose from your mom or dad?
From both. Nose shape is shaped by many genes, and each gene variant found in a large 2016 study explained only about 1% of the variation in its trait, so the result is a mix of what came from both sides of the family (2016 study).
What nose shape do Latin Americans have?
There isn't one. In a study of about 6,000 Latin Americans, average estimated ancestry was roughly 50% European, 45% Native American and 5% African (2016 study).
Are nose shapes the same within an ethnic group?
No. There is more genetic variation within self-identified racial groups than between them (NHGRI).
Can nose shape change over time?
Yes, in adulthood. A study that followed 48 Korean adults for at least 10 years found that noses got longer and the tip angled lower (2023 study). A CT study of 200 Asian adults found a more drooping tip, thicker nasal skin and signs of bone loss in people aged 65 to 80 compared with people aged 20 to 35 (2022 study). Both samples were Asian, so the exact changes may differ in other groups.
