How do I know if my face is diamond shaped?

A diamond face is widest at the cheekbones by a clear margin, with a narrower forehead above and a narrow, often pointed chin below. It is the rarest of the six common shapes, and the easiest to misread as oval or heart.

Best glasses for a diamond face

A diamond face is widest at the cheekbones, with a narrower brow above and a narrow chin below. The cheekbones are the feature. The best frames stay out of their way and add a little width up top to balance them.

First, check that your face is diamond

Diamond is the rarest of the six common shapes, and the easiest to misread. Check for these traits.

The cheekbones are the widest point, by a clear margin.
The forehead is narrower than the cheekbones.
The chin is narrow, and often pointed.
The outline tapers both up and down from the middle.

Forehead the widest point instead? That is heart. Balanced all the way down? Read the oval guide.

Frames that work, and why

Two goals. Keep the cheekbones open, and give the narrow brow line a little more presence. Light builds do the first. Upswept and top-emphasis shapes do the second.

Rimless frames are the signature pick. Vision corrected, cheekbones untouched.
Ovals keep every line soft and stay clear of the cheekbone peak.
Cat-eyes sweep upward and give the brow line the width it lacks.
Browlines do the same with a straight bar instead of a sweep.

Frames to skip

Narrow frames pinch exactly where your face is widest, which exaggerates the contrast. Heavy boxy frames compete with the cheekbones instead of framing them. Keep the build light, and keep the width honest against your face width. The size stamp guide shows which numbers to check.

High, prominent cheekbones taper to a narrower forehead and chin. Light or upswept frames keep them open.

SpecFit checks where the face reaches its maximum width. For this subject, the cheekbones clearly exceed the forehead and jaw, producing the diamond result shown above.

Questions

Why are rimless glasses good for a diamond face?

The cheekbones are the feature. A rimless frame corrects your vision without drawing a line through or near them. The strongest part of the face stays open.

What should a diamond face avoid?

Narrow frames that pinch at the cheekbone line, and heavy boxy frames that compete with it. Both point at width in the wrong place.
