Glasses for a diamond face
A diamond face suits glasses that add width at the brow and keep the lines soft: browline, cat-eye and oval frames, sitting just inside the cheekbones. They balance wide cheekbones against a narrower forehead and chin. Rectangle and geometric frames are harder, because their angles sharpen the widest point. Frames change the impression, not the cheekbones themselves.
Is your face diamond?
- Even light
- Neutral expression
- Phone at eye level
- Clean background
- Even lightFace a window. No harsh shadows from above.
- Neutral expressionNo smile, no makeup. Hair off your forehead.
- Phone at eye levelShoulders to top of head. Chin neither up nor down — angle can fake a sharper jaw.
- Clean backgroundPlain wall or neutral space.
The short version
- 1Confirm that your face reads diamond. Take a straight photo at eye level with the hair off the forehead and run the face shape detector at the top of this page. A heart or oval reading takes different advice, so check the shape first.
- 2Start with frames that are fuller at the brow. Try browline, cat-eye and oval frames first, then a rectangle or geometric frame for comparison, and watch how the cheekbones read in each photo.
- 3Set the width just inside the cheekbones. Use the narrower setting and check that the outer edges of the frame sit a little inside the face at cheekbone height, neither past it nor far within it.
- 4Put colour at the top and keep the bottom light. Choose a dark or tortoise brow bar with a thin metal or crystal lower rim, and check that the lower rim clears the cheekbones when you smile.
- 5Check the bridge and your pupillary distance. Set the bridge or nose pads so the frame sits level and clear of the cheeks, and give the optician your pupillary distance with a strong prescription.
What a diamond face is, and what to balance
A diamond face is widest at the cheekbones, with a narrower forehead above and a narrower, often pointed chin below. The temples can look slightly hollow beside the cheekbones, and the face is usually longer than it is wide. In the glasses by face shape chart it is the shape that lacks width above and below the middle. The cheekbones themselves, the zygomatic bones, are often its strongest feature.
Glasses sit just above the widest point, so they can add width where the face narrows, at the brow and temples, and leave the cheekbones alone. A frame that is fuller at the top does that; a frame with hard angles at its outer edge points straight at the cheekbones. This is optical and styling convention rather than research, and it changes how the face reads, not its structure.
Frames that suit a diamond face, and the ones that are harder
| Frame | Verdict | Why |
|---|---|---|
| Browline | Suits | A strong bar along the brow adds width to the narrow forehead, and the light lower rim leaves the cheekbones alone |
| Cat-eye | Suits | The upswept outer corner widens the upper face and draws the eye up from the cheekbones |
| Oval | Suits | Soft curves with no corners to sharpen the angles of the cheekbones and chin |
| Rectangle | Harder | Straight lines and hard outer corners at cheekbone height emphasise the widest point |
| Geometric | Harder | Faceted angles repeat the angular outline of the face itself |
Round, square, wayfarer and aviator frames sit between the lists. A round frame is soft but adds no width at the brow; a wayfarer has the heavy top edge a diamond face can use, and with softened corners it often works. Aviators are worth a try if the brow bar is strong. Rimless and semi-rimless frames are another common choice for diamond faces, because they keep the cheekbones uncluttered.
Width, colour and rim weight
Keep the frame just inside the cheekbones. A frame that reaches past the cheekbones adds width to the one part of the face that has plenty, while one far inside them makes the cheekbones look wider by contrast. Just inside lets them show as a feature without competing with the frame.
Put the colour and weight at the top. A black or tortoise browline bar, or a cat-eye in tortoise, adds definition at the brow. Gold and silver wire keep the lower half light, which is why a browline with a metal lower rim suits so many diamond faces. Crystal works for anyone who wants the frame to recede. Avoid heavy colour along the lower rim, which pulls the eye down toward the cheekbones.
Bridge, pupillary distance and strong prescriptions
Face shape says nothing about the nose. A narrow, high bridge suits a keyhole fit; a low or wide one needs nose pads or a low bridge fit. On a diamond face the bridge also sets the lower rim's height relative to the cheekbones, so adjustable pads help.
Your pupillary distance places each lens centre over a pupil. Get it from the prescription or an optician; the pupillary distance tool estimates a band from a photo, enough to choose a frame width. A narrow frame helps a strong prescription, because smaller lenses mean thinner edges and less distortion. A thick lens edge at the outer rim can also look like extra width at the cheekbones, so ask for high-index lenses with a strong prescription.
Sunglasses for a diamond face
Cat-eye and browline sunglasses suit best, with oval sunglasses close behind. Avoid narrow angular sunglasses and sporty wraparounds that run straight across the cheekbones. Sunglasses can be slightly larger than prescription frames, but on a diamond face the extra size should go up toward the brow, not out past the cheekbones.
Frames, hair and a beard all frame the same outline. The diamond-face pages for hairstyles and beard styles add width at the forehead and chin in the same spirit. If the face shape detector reads your face as heart or oval instead, compare the heart and oval pages; a diamond face with a wider forehead is often read as heart.

Questions
Why do browline glasses suit a diamond face?
Because a diamond face is narrow at the forehead and widest at the cheekbones. A browline's heavy upper bar adds width and definition at the brow, while its thin lower rim leaves the cheekbones uncluttered, so the upper and middle face read closer in width.
Should frames on a diamond face be wider than the cheekbones?
No, just inside them. The cheekbones are already the widest part of a diamond face, and a frame that runs past them adds width there. A frame slightly narrower lets the cheekbones show as a feature without the frame competing with them.
What sunglasses should a man with a diamond face wear?
Browline-style sunglasses, wayfarers with softened corners and aviators with a strong brow bar suit most men with a diamond face. Avoid narrow angular wraparounds that cut straight across the cheekbones, and keep the width just inside them rather than past them.
