Heart vs Diamond Face Shape: What Changes

Heart and diamond faces share a narrow lower face and a pointed chin, which is why they are easy to confuse in a photo. The useful difference is the widest band. A heart face is widest at the forehead. A diamond face is widest at the cheekbones. The jaw is narrow in both, but the top of the face tells the two apart.

The short answer

Question	Heart	Diamond
Widest band	Forehead	Cheekbones
Forehead	Wide, often the widest part	Narrower than the cheekbones
Cheekbones	Wide, but not the widest	The widest part
Jaw and chin	Narrow, often pointed	Narrow, often pointed
Main styling risk	Adding more width at the top	Adding width at the cheekbones
Full guide	Heart face guide	Diamond face guide

A heart face can have prominent cheekbones; a diamond face can have a broad forehead. The label comes from the order of the widths, not from whether one feature is noticeable. Compare the forehead, cheekbone and jaw lines together.

What both shapes share

Both have a lower face that tapers. Both can have a pointed chin, and both can look narrower at the jaw than at the upper face. Hair that falls straight down from the widest band can make that band look wider; a fringe, a side part or a change in volume can move the eye.

The jaw and chin are the narrow end in both shapes. A beard can fill that end, and a haircut can add width at the temples or below the cheekbones. The bone underneath is what the label describes; the hair and beard change the outline you present.

The measurement that separates them

Start with three widths: forehead, cheekbones and jaw. On a heart face the forehead is the widest. On a diamond face the cheekbones are the widest. The jaw is narrower than both in either shape.

The second check is the hairline and temple. A heart face often has a broad, straight or rounded forehead. A diamond face often has a narrower forehead with more recession at the temples. A fringe can hide that difference in a photo, so pull the hair back for the measurement.

The photo detector and the quiz do not measure the same way. The quiz asks you to compare the widths in a mirror; the photo detector reads landmarks on a picture. A close result is common. Read how the measurements work before treating a difference between the two tools as an error.

Why photos and mirrors move the line

A high camera widens the forehead and can make a diamond face look more like a heart. A low camera widens the jaw and can make either face look less tapered. A wide-angle lens stretches the outer edges of the frame, especially at the cheekbones.

Hair over the temples hides the forehead width. A beard adds width at the jaw and can make a pointed chin look rounder. A neutral expression, a level camera and hair pulled back give the cleanest comparison.

Hair, glasses and beard: the practical difference

On a heart face, the forehead is already the wide part. Keep the top quiet and put weight low, near the jaw and the lower cheek. A side-swept fringe or a part that covers one temple narrows the upper line. Fullness around the jaw fills the narrow bottom. Crown volume plus very short sides makes the forehead look wider.

On a diamond face, the cheekbones are the wide part. Put width at the forehead and jaw, and keep the middle smooth. A fringe or forward texture fills the narrow forehead; fullness near the jaw fills the chin. Hair that kicks out at the ear sits on the widest bone and makes the diamond sharper.

Glasses follow the same logic. A heart face often benefits from a lighter top or a wider lower rim; a diamond face often benefits from top detail or width at the temples. The glasses guide explains frame width and bridge fit.

A beard can fill the narrow lower face in both shapes. On a heart face, fill along the jaw and round the bottom edge instead of pointing it. On a diamond face, put bulk on the chin and lower jaw and keep it off the upper cheek. The beard guide covers shape-by-shape trims.

A 30-second check

1. Pull the hair back and compare forehead, cheekbone and jaw widths.
2. Ask which band is widest: forehead or cheekbones.
3. Look at the forehead: broad across the temples, or narrower than the cheeks?
4. Notice whether the chin is pointed in both; that does not separate the two.

For a second estimate, take the face shape quiz or use the face shape detector.

Frequently asked questions

What is the difference between a heart and a diamond face?

The widest band is the difference. A heart face is widest at the forehead and tapers to a narrower chin. A diamond face is widest at the cheekbones, with both the forehead and the jaw narrower and a more pointed chin.

Can a heart face have wide cheekbones?

Yes. The cheekbones can be wide on a heart face, but the forehead is still the widest part. On a diamond face the cheekbones are the widest part, ahead of both the forehead and the jaw. Compare all three widths before choosing the closer label.

Which haircut suits both heart and diamond faces?

Both benefit from width below the cheekbones and a quieter top. For heart, a side-swept fringe and fullness near the jaw balance a wide forehead. For diamond, a fringe or forward texture fills the narrow forehead while the middle stays smooth. Avoid a heavy block of hair on the widest band.

What glasses suit heart and diamond faces?

A heart face often suits a frame with a lighter top or a wider lower rim, so the eye is not pulled to the forehead. A diamond face often suits top detail or a frame that adds width at the temples. In both cases, the frame should not pinch at the widest point of the face.
