Method
How it works and the exact formula
Frames sit in the middle of your face, so they change your proportions more than any other accessory. The classic rule is contrast: angular frames for soft faces, curved frames for angular faces, and frame width that matches the widest part of your face at the temples. This tool applies that rule to your measured face, not a guessed shape.
MediaPipe Face Landmarker places 478 landmarks in your browser and we level your face on the line between your iris centers. From the landmarks we compute your face shape ratios and, specifically for eyewear, your eye-spacing ratio: interpupillary distance divided by cheekbone width. Eye spacing decides the bridge: wide-set eyes look closer with a dark or thick bridge, close-set eyes look wider with a clear or keyhole bridge.
We also use your canthal tilt and thirds. Upturned eyes balance well with straight browlines; downturned eyes benefit from frames whose top line rises toward the temples. A long middle third is broken up by frames with a strong top bar or a low-set bridge, while a short middle third prefers lighter, higher-set frames.
The free result lists four frame styles for your face shape with a reason for each. The full report renders four frames on your real photo with identity-preserving AI, and the Try-On Studio lets you upload a product photo of any pair to see a compatibility score and the frames on your face.
Fit matters as much as shape. Your pupils should sit near the horizontal center of each lens, the top of the frame should follow your brow line rather than cut across it, and the frame should be about as wide as your face at the temples. Frames narrower than your cheekbones make the face look wider, and frames that extend well past the temples make it look smaller. The landmarks we use, iris centers and cheekbone edges, are the same reference points an optician uses for these checks.
Lens prescription also changes the look: strong minus lenses make eyes look smaller and benefit from smaller, thicker frames that hide lens edges; strong plus lenses magnify and suit frames with smaller lens heights. If you wear a strong prescription, ask your optician about high-index lenses before choosing an oversized style.
Formulas
- Length-to-width
- LWR = |L10 − L152| ÷ |L234 − L454|
- Forehead-to-cheek
- F2C = |L103 − L332| ÷ |L234 − L454|
- Jaw-to-cheek
- J2C = |L58 − L288| ÷ |L234 − L454|
- Eye spacing
- |L468 − L473| ÷ |L234 − L454| (balanced ≈ 0.46)
- Frame width target
- frame width ≈ cheekbone width at temple height
MediaPipe landmarks used
| Anatomical point | Index | Role |
|---|---|---|
| Iris centers | 468 / 473 | Level the face so widths are measured on a true horizontal. |
| Trichion (proxy) / menton | 10 / 152 | Face length. |
| Zygion | 234 / 454 | Cheekbone width: the reference width for every ratio. |
| Forehead edges | 103 / 332 | Forehead width (heart vs. diamond). |
| Gonion (proxy) | 58 / 288 | Jaw width (square vs. tapered). |
| Eye corners | 33 / 133 / 362 / 263 | Canthal tilt and the gap between the eyes (bridge choice). |
Benchmarks
Eye-spacing bands and bridge advice
| Metric | Band | Value range | Tool score | Modelled percentile |
|---|---|---|---|---|
| Eye spacing | Close-set | 0.40 – 0.43 | 14–61 | 1st–52nd |
| Eye spacing | Balanced | 0.44 – 0.48 | 80–100 | 87th–99th |
| Eye spacing | Wide-set | 0.49 – 0.52 | 14–61 | 1st–52nd |
Close-set eyes: clear or keyhole bridge, lighter inner rims. Wide-set: darker, thicker bridge. Percentiles are modelled from the reference distribution our scorer uses (scores are mapped through a normal curve, mean 60, SD 18), not from a database of user faces. We don't build one: selfies are deleted within 2 hours and free scan results after 48 hours.
Styling
Styling and virtual try-on by result
Frame shape by face shape, with the specific styles the try-on renders.
Round
Rectangular, square and geometric frames slightly wider than your face; dark or sturdy acetate. Avoid small round frames.
Rate a rectangular frameSquare
Round, oval and aviator frames soften the jaw; browlines draw the eye upward. Avoid small, sharp rectangles.
Check how square your jaw isOblong
Deep, wide frames such as oversized squares and bold browlines break up length. Avoid narrow, shallow frames.
Measure your length-to-widthHeart
Bottom-heavy, light-rimmed or rimless frames, ovals and soft cat-eyes balance a wider forehead.
Confirm heart vs. ovalDiamond
Browline, oval and rimless frames widen the forehead and chin around prominent cheekbones.

Match frame tone to your color season: tortoiseshell and gold for warm seasons, black, grey and silver for cool seasons.

What glasses suit my face shape?
Use contrast: round faces suit rectangular frames, square faces suit round and oval frames, oblong faces suit deep, wide frames, heart faces suit bottom-heavy or rimless frames, and diamond faces suit browlines and ovals. Oval faces suit almost everything.
How do I choose glasses for wide-set eyes?
Choose a darker or thicker bridge and frames with more weight near the nose. They bring the eyes visually closer together. The tool measures your eye spacing to tell you which group you're in.
How wide should my glasses be?
The frame should be about as wide as your face at the temples, with your pupils roughly centered in each lens. Frames narrower than your cheekbones make the face look wider.
Can I try on glasses virtually with my own photo?
Yes. The full report renders four frames on your real photo, and the Studio lets you upload a photo of any specific pair to get a compatibility score and a render on your face.
What glasses make you look younger?
Frames that lift the eye line: soft cat-eyes, browlines and frames whose top line follows or sits slightly above the brow. Lighter colors and thinner rims also look fresher than heavy dark frames.
Do aviators suit a round face?
Aviators can work on round faces if the frame is angular and wide enough. Classic teardrop aviators suit square, heart and oval faces best.
Should frames match my brows?
The top of the frame should follow the brow line and not cut through the brows. A frame that sits well below the brows lengthens the midface.
What glasses suit a heart-shaped face?
Bottom-heavy frames, light or rimless styles, ovals and soft cat-eyes balance a wider forehead and narrower chin. Avoid heavy, top-weighted browlines.
