Diamond face shape hairstyles for men, short to long.
High cheekbones, narrow forehead and chin? That is a diamond face, and few cuts go wrong on it. The best ones add width at the forehead with a fringe or volume, or fill out the chin with length. Skip bare sides with nothing on top. Below: 12 cuts and what to tell your barber.
Key takeaways
At a mirror, measure across your forehead, your cheekbones and your jaw. On a diamond face the cheekbones are clearly the widest. The forehead is about 0.82 times the cheekbone width, the narrowest of any shape, and the chin is narrow and pointed.
| Shape | Forehead | How to tell |
|---|---|---|
| Diamond | 0.82 | Wide cheekbones, narrow forehead and chin |
| Heart | 0.91 | Wide forehead, narrow chin |
| Oval | 0.86 | Soft and balanced, no wide spot |

A beard is the easiest way to fill out a narrow chin. Keep the cheeks trimmed and let the chin and jaw carry the weight.
Full Beard
Fills out a narrow chin.
Short Boxed Beard
Widens the jaw line.
Balbo Beard
Weight at the chin, not the cheeks.
Heavy Stubble
A shadow that adds a jawline.
Few cuts go wrong on a diamond face. These two leave the forehead bare, so the cheekbones look wider.
No hair at the temples
With no hair, nothing widens the forehead, so the cheekbones look wider.
Bare sides with a tall, narrow strip
A narrow strip on top makes the forehead look narrower and the cheekbones wider.
Volume at the front
Blow dry the front up or forward. That is where a diamond face needs width.
Flat at the sides
Keep product off the sides, so the cheekbones stay calm.
A middle part works
Pieces falling to each side of the forehead widen it.
Shape the beard low
Trim the cheek line low and keep length at the chin.
Cuts that add width at the forehead: a textured fringe, a French crop, a modern pompadour or a middle part. Longer hair past the jaw also fills out a narrow chin.
Measure across your forehead, cheekbones and jaw. On a diamond face the cheekbones are clearly the widest part, the forehead is narrow (about 0.82 times the cheekbone width) and the chin is narrow and pointed.
Yes, with volume on top. A mid or high fade with 2 to 3 inches of textured hair on top widens the forehead and keeps the sides neat by the cheekbones.
Very few. A shaved head and a mohawk with bare sides make the forehead look narrower and the cheekbones wider. Most other cuts work.
A full beard, a short boxed beard or a Balbo. They add width at a narrow chin and balance wide cheekbones. Keep the cheeks trimmed.
We kept the cuts that suit a diamond face best, added three fringe and framing cuts that also work, and grouped them by length. Guard numbers come from each cut's catalog description. One model in every cut photo, so you compare cuts, not faces.
