Base width
The distance from your left nostril wing to your right one.
Free AI Tool — Straight-Up Ratio Read
Nose Shape Detector
A nose shape detector is an AI tool that places landmark points across your nose in a front-facing photo and measures the width of the base against the length of the bridge, then reports that ratio as wide, balanced, or narrow.
Most nose-shape quizzes hand you a label pulled from a list of eight or ten named types. This one hands you a number instead, along with the two measurements that built it — because a single photo, taken straight-on, can only tell you so much, and we'd rather report what it shows than guess at what it can't.

What Gets Measured
Nine points, not the sixty-eight used across the rest of the site, is what this particular reading runs on — four running down the bridge, five spread across the base. Everything else on FaceShapesAI leans on the full 68-point landmark map; a nose read from the front only needs this smaller cluster.
Bridge length
The distance from the top of the bridge down to the tip.
The ratio
Base width divided by bridge length — one figure, built from two measurements.
No depth
A front-facing photo carries zero information about how far anything projects toward the camera, so profile features are simply outside what this reading can see.
That last point is worth sitting with. This is the most limited tool on the site, and it's limited on purpose rather than by oversight — a flat image can locate where features sit across the face, but it has nothing to say about how they project forward. A bridge hump, a drooping tip, an upturned tip: none of that shows up in a straight-on photo, no matter how good the landmark model is. What a front view does support, reliably, is the one comparison this tool reports.
Reading the Ratio
Say your base width comes back at 38mm and your bridge length at 52mm. Divide the first by the second and you land at roughly 0.73 — solidly in the middle band. Three outcomes cover the full range, because three is what this particular measurement can honestly support.
Above 0.80
Wide
The base spreads noticeably relative to how long the bridge measures.
0.50 – 0.80
Balanced
Base and bridge sit in proportion to each other. Most results land here.
Below 0.50
Narrow
A compact base paired with a comparatively longer bridge.
Getting a Fair
Measurement
Why does the same face sometimes come back wide and sometimes narrow between two different scans? Almost always, it's the camera angle doing the work, not your actual structure.
Camera at eye level
Tilting your chin up shortens the visible bridge and pushes the ratio sharply higher.
Square to the camera
Any turn of the head foreshortens one nostril wing, which narrows the measured base.
Even, frontal light
Light coming from the side casts a shadow that pulls the wing landmark points inward, throwing off the base reading.
Relaxed expression
A wide smile lifts and flares the nostrils more than most people expect, moving the number without moving your actual anatomy.
How the Detector Works
1
Upload Photo
One clear, front-facing photo, camera at eye level.
2
Points Located
Four landmarks down the bridge, five across the base.
3
Ratio Measured
Base width divided by bridge length.
4
Result Given
Wide, balanced, or narrow, plus the exact figure behind it.
Pair it with the eye shape detector or the lip shape analyzer if you want more than one reading from the same photo — each runs its own landmark subset and reports its own numbers.

Why Only Three Outcomes
Ask a typical nose-shape list for a category and you'll get eight or ten options — Roman, Greek, button, hawk, snub, celestial, and a handful more. Nearly every one of those is defined by the profile line: whether the bridge runs straight, humped, or scooped, and which way the tip turns.
None of that is visible from the front. Landmark points record where features sit across a flat image; they carry no signal about how far anything projects toward the lens. Sorting a front-facing photo into one of ten profile categories would mean inventing an answer the data doesn't contain.
Three bands is what the base-to-bridge measurement supports. A trustworthy number beats a confident-sounding label built on nothing.
What Would Be Needed for More
Picture a second photo — this one taken side-on — run through a landmark model built specifically for profile views instead of frontal ones. That's the shortest path to a real bridge-and-tip reading, and it's a separate detection step rather than an upgrade bolted onto this one.
The standard landmark set used elsewhere on the site is built for frontal faces and degrades badly the moment a head turns to the side. A profile-specific model is buildable, and it's on the list if enough people want it — but shipping a frontal-only tool that pretends to read bridge humps and tip angles would produce results that look precise while meaning nothing.
Reading Your Number Sensibly
Tip your chin up by an inch or two and the same nose can drift from balanced into the wide band without a single physical change taking place. The ratio moves with camera height more than almost any other reading on this site, because raising your chin shortens the visible bridge while the base barely shifts at all.
If a result catches you off guard, retake the photo with the camera held level with your eyes before drawing any conclusion from it. And worth keeping in mind separately: nose width correlates strongly with ancestry. No width scores better than another here, and this tool was never built to rank them against each other.

Frequently Asked Questions
It places nine landmark points on your photo — four down the bridge, five across the base — measures base width against bridge length, and reports the ratio as wide, balanced, or narrow.
Because a front-facing photo can't show profile features like bridge humps or tip angle, which is what most named nose-shape categories are built on.
No. A face-shape read looks at your whole facial outline; this tool isolates one part of the face and reports a single width-to-length ratio for it.
The distance from your left nostril wing to your right nostril wing, measured straight across.
The distance from the top of your nose bridge down to the tip.
No. Those are profile features, and a front-facing photo carries no depth information — the landmark points simply can't see them.
Usually camera angle. Tilting your chin up, turning your head, or uneven lighting all shift where the landmark points land, which moves the ratio even though your actual nose hasn't changed.
Front-facing, camera at eye level, even light, and a relaxed expression — a plain ID-style photo outperforms an angled or smiling one every time.
No. Your photo is processed by our own in-house model and deleted from the server immediately after your result is generated. What you see afterward lives only in your browser's cache — refresh the page and it's gone for good, on both ends.
Yes — two free scans a day, no account required.
No. The two daily scans work without signing up; creating a free account simply raises that daily limit.
Yes, strongly, and that's expected — this tool doesn't rank one width as better or worse than another, it just reports the measurement.
Yes, more than people assume. A wide smile flares and lifts the nostrils, which can shift a balanced reading toward wide. A relaxed, neutral expression holds up better.
Glasses that sit low on the bridge or cast a shadow across it can interfere with the bridge points. A photo without them, or with them pushed up clear of the bridge, gives a cleaner read.
Yes — the source data behind this detector is explicit about that. Tilt shortens the bridge and pushes the ratio up; turning the head narrows the base by foreshortening one nostril wing. Both distort the number, but tilt does it faster.
It's buildable and on the list, but it needs a second, side-on photo and a landmark model trained specifically for profile views — the frontal 68-point system used elsewhere on the site isn't built for that angle.
Yes — your reading, the ratio behind it, and your nose outline can be shared straight to social media as a styled card.
No. The detector reads one face per photo; a second face in frame can interfere with the landmark points and throw off the measurement.
Two, tracked by browser and IP address.
Not by this tool's bands — 0.79 falls just inside Balanced, since the Wide threshold starts at 0.80. It's close enough that a slightly different camera angle could push a retake either way.
