Contrast, Not Match
An angular frame sits well on a round face, and a curved frame sits well on a square one — each brings the line the face is short on.
Free AI Tool — All 7 Face Shapes
Glasses Frame Finder
A glasses frame finder is an AI tool that maps your facial landmarks to measure your face shape, then returns the frame shapes that balance that shape against the ones that work against it.
Round, square, heart, oblong — every shape carries its own set of lines, and a frame either argues with those lines or just repeats them. Upload one photo and the measurement tells you which frames are doing which job before you ever try one on.

How Frames Are Matched
What makes one frame flatter a face while an almost-identical frame does nothing at all? The answer comes down to a single word: contrast. A frame that runs against the lines already on your face reads as balance. A frame that repeats those lines just adds more of the same.
Width Matters
A frame that stops well short of your widest point makes the face look wider by comparison. One that reaches close to that edge is the safer default.
Where the Weight Sits
A heavy brow bar adds visual weight to the upper face, while a rimless lower edge lightens the jaw beneath it.
Convention, Not AI
The measurement step is automatic. The styling advice attached to it is optical-industry convention, written by people rather than generated by the model.
Picture two faces: one with soft, curved edges and no strong corners, the other built around a squared jaw with defined angles. The first gains structure from an angular frame. The second gets relief from a round or oval one. Nearly every recommendation on this page traces back to that one swap.
Width is the second variable worth tracking. A frame that ends a few millimetres inside your temple width tends to shrink the face in the photo; one that reaches just past it can look borrowed from a bigger face. Landing close to your natural edge is usually the safer middle ground.
The measurement itself runs on the same 68-point landmark map used across the rest of the site — the same grid that reads eyes, jaw, and cheekbones for every other face-shape tool here. What the AI does is measure that shape; it doesn't pick your glasses for you. The recommendation layered on top is convention matched to what got measured, and it stops short of judging how a given frame sits on your particular nose bridge. Sunglasses run on the identical contrast logic, just scaled up for a bigger frame — see the sunglasses shape guide if you're shopping for both at once.
The Full Frame Match Chart
What a scan gives back is one shape and its frame matches — nothing about why. Set next to the other six, the contrast principle behind that pairing is easy to check for yourself.
Seeing a round face next to an oblong one, each paired with the frames that suit it, makes the contrast rule easier to trust — the same principle produces a different answer for every shape, rather than asking you to take a single recommendation on faith. It also doubles as the fastest way to sanity-check your own result: find your shape in the full lineup and see whether the logic matches what you'd expect once it's laid out in front of you.
Before You
Buy
Face shape is one input. What happens next comes down to how a specific frame sits on a specific face, and a shape reading alone can't answer that.
A frame can score a perfect match on shape and still be the wrong frame the moment it's on your nose. Four things below sit outside anything a face-shape result can tell you.
Check the Bridge Fit
A frame that slides down your nose within the hour is wrong regardless of what the shape match says — bridge fit overrides everything above it.
Pupil Position
Your eyes should land near the centre of each lens, slightly above the midline. Off-centre pupils usually mean the frame is the wrong width or sits at the wrong height, not that the shape call itself is wrong.
Frame Weight
Heavier acetate needs a bridge and temple built to carry it. A shape that suits your face on paper can still feel wrong within a day if the material is heavier than your nose is used to.
Try Before Buying
Two minutes in front of a mirror in-store settles more than any rule on this page. Shape narrows the field; trying it on decides the winner.

Why Contrast Is the Whole Rule
Zero straight lines, zero sharp corners — that's roughly what a round face outline looks like, which is exactly why an angular frame reads as structure the moment it's added.
A face registers as round because its outline runs in one continuous curve, without the corners a jaw or cheekbone might otherwise supply. Drop a rectangular frame into the middle of that curve and you introduce a straight edge and a corner at once — the eye reads the difference as definition, not decoration.
The same logic runs in reverse. A square jaw already contributes plenty of angle on its own, so a frame built from more right angles just doubles down on a line the face didn't need more of. A round or oval frame is what softens it.
Once that idea is in place, you don't need a separate rule for every frame you'll ever see in a shop. Ask what line a given frame adds — straight or curved, sharp or soft — and whether your face is short on that line or already carrying plenty of it. The answer tells you more than any category label would.
Where Frame Advice Stops Being Useful
A frame in the theoretically correct shape can still be the wrong frame. One that slides down your nose within the hour, or pinches at the temples by lunchtime, will look worse than a compromise shape that sits still.
Colour is a separate question entirely, and it runs on your skin's depth and undertone rather than the outline of your face — a shape reading has nothing useful to say about it. The skin tone analyzer covers that side of the decision, applying the same kind of measurement to colour instead of shape.
About This Tool
The measurement behind this page didn't come from a licensed third-party API — Ahsan Fayyaz trained the model in-house on real faces and benchmarked it against other face-shape tools. It's the same engine behind every face-analysis tool on the site. The styling guidance is informational only: convention drawn from optical-industry practice, not medical, clinical, or professional advice, and it doesn't replace a proper fitting from an optician.

Frequently Asked Questions
It places 68 landmark points across your eyes, jaw, and cheekbones, converts those into a face-shape reading, and matches that shape to written frame guidance based on the contrast principle — angular against round, curved against square.
No — it names three frame shapes that suit your measured face, not a specific product or brand. What you buy within that shape is still up to you.
All seven of the standard categories, so your result always lands in one of them rather than a leftover "other" bucket.
Same measurement, same contrast principle, different frame sizes. The sunglasses shape guide applies the identical logic to larger lenses, where coverage and lens size carry more of the decision than they do with everyday glasses.
Yes, if you can. Reflections off your lenses, and the frame itself covering your brow and temple, can block the landmarks the model needs — especially around the bridge and the outer eye corners.
Your photo is processed by our own in-house model, never a third-party service, and it's deleted from the server right after your result comes back. What's left afterward sits only in your browser's cache, and refreshing the page clears it for good on both ends.
Two free scans a day, no account required.
Most faces lean toward one shape more than the others even when they're not a textbook example of it. The measurement finds the closest of the seven categories rather than forcing a perfect fit, so a borderline face still gets a usable answer.
It happens less often than the reverse, but yes — say a square-jawed face and a diamond-shaped one both come out short on curves in roughly the same places. Both can land on a similar rounded frame even though the rest of their proportions look nothing alike.
No. It names frame shapes, not products or stores.
A relaxed expression works better than a big smile. Smiling shifts your cheeks and the corners of your eyes enough to nudge the jaw and cheekbone measurements the whole shape call depends on.
It can, if it covers your jawline. The model reads the jaw as one of its main landmarks, so heavy facial hair along that edge can shift where your shape lands.
The two are measuring different things. An optician looking at you in a fitting room factors in your skin tone, your existing prescription, and how a frame physically sits on your particular nose — all in the moment. This tool only measures outline geometry from a photo. It's a strong starting point for narrowing three shapes down from dozens, not a replacement for the fitting itself.
No. Both daily scans work without one.
JPG, PNG, or WEBP, up to 10MB. A plain front-facing shot with even lighting gives the cleanest read.
Yes — your result can be shared as a styled image, sized for either a square post or a story.
Because the two jobs are different. The AI's job stops at measuring your proportions accurately. The frame guidance layered on top of that measurement is optical-industry convention — decades of styling practice — matched to whatever shape the model found. Keeping that split explicit is more honest than pretending a face-shape score alone can pick your glasses for you.
Yes. A fringe hiding your hairline, or hair falling across your jaw, removes landmarks the model relies on for the upper and lower boundaries of your face, which can pull the result toward the wrong shape.
No — colour depends on your skin's depth and undertone, not your face outline. That's a separate reading, covered by the skin tone analyzer.
