Oval
Barely thereGently rounded and wider than tall — the least demanding frame shape there is.
Why it works: Softens angles without the commitment of a fully round lens, and stays narrow enough not to widen a face at the cheekbone.
Glasses guide
A heart-shaped face is widest at the forehead and cheekbones and narrows to a fine chin. Glasses sit right at the widest part, which makes this the shape where frame choice changes the most.
The task is to avoid adding width where the face is already wide, and where possible to move visual weight downward. Light frames and bottom-weighted shapes both do that.
This is also the shape where frame width matters most in absolute terms. A frame overhanging the temples is visible on any face, but on a heart-shaped one it lands at the single widest point, so the same few millimetres of overhang show far more than they would on someone else.
Whatever the shape, the frame should be about as wide as your face at the temples, and your pupils should sit near the centre of each lens — a little above centre is fine, low is not. A frame that fails this fits badly no matter how well the shape suits you.
A heavy browline or thick top rim. It lands a dark horizontal bar across the widest part of the face, which broadens the forehead and makes the chin look narrower by comparison. Browline frames suit a diamond face for exactly the reason they fail here.
Every one of these carries the reason it works, so you can judge a frame that isn’t on the list.
Gently rounded and wider than tall — the least demanding frame shape there is.
Why it works: Softens angles without the commitment of a fully round lens, and stays narrow enough not to widen a face at the cheekbone.
Lifted outer corners with the weight of the frame concentrated along the top.
Why it works: Puts width and interest at the browline, which lifts a narrow forehead and draws the eye up and away from a heavy jaw.
Teardrop lenses, wider at the top and tapering toward the bottom, on a thin metal frame.
Why it works: The taper narrows toward the cheek, so it echoes a face that already narrows to the chin instead of fighting it.
Large lenses with real vertical depth, covering from brow to upper cheek.
Why it works: Depth is the point: a tall lens breaks a long face horizontally and shortens it, which no narrow frame can do.
Lenses mounted directly to the bridge and temples with no surrounding frame.
Why it works: Adds almost no visual weight, so it never competes with a face whose own structure is already the feature.
Frames where the lower rim is thicker or darker than the upper — the reverse of a browline.
Why it works: Moves visual weight down toward a narrow chin, balancing a face that carries all its width at the top.
Each adds weight or width at the top third of the face, which is the one place a heart-shaped face has plenty of both. A frame overhanging your temples is the most visible version of the error.
Aviators are a natural fit — the taper narrows toward the chin the way your face does, and the thin metal adds no bulk at the brow. Oversized shades also work, provided they are deep rather than wide, so the weight sits over the cheek rather than out past the temple.
A wide forehead and cheekbones tapering to a narrow, often pointed chin. Frequently comes with a widow's peak.
