Diamond Face Shape: Do Your Cheekbones Lead?
Upload a photo, use your camera, or enter four measurements. This tool reads 468 landmark points, detects your jaw contour, and scores all 8 face shapes so you see the runner up too. Nothing is uploaded.
Measure My Face Shape ›Quick answer: You have a diamond face shape when your cheekbones are the widest part of your face, with both your forehead and your jaw measurably narrower, and a chin that tapers to a point. The threshold used here is stated openly: cheekbone width at least 8 percent greater than both forehead and jaw width. Diamond is easy to misread, because it shares a pointed chin with heart and cheekbone led width with oval. The section below shows the single check that separates each pair.

What Is a Diamond Face Shape?
A diamond face shape is wide in the middle and narrow at both ends. Your cheekbones are the widest measurement on your face. Your forehead is narrower. Your jaw is narrower too, and your chin comes down to a point. Draw an outline around it and you get something close to the gemstone.
The bone structure behind it is simple. The zygomatic bones, which are your cheekbones, sit high and project outward. The frontal bone above them is comparatively narrow, and the mandible below tapers in toward the chin.
The measurable definition used on this page
- Cheekbone width is the largest of the three widths
- Cheekbone width is at least 8 percent greater than forehead width
- Cheekbone width is at least 8 percent greater than jaw width
- The jaw contour narrows to a point rather than holding its width
- Length divided by cheekbone width usually lands between 1.35 and 1.55
Where the 8 percent comes from: it is our chosen line, not an official standard, because no official standard exists. Published guides use anything from 5 percent to 10 percent, and many use no number at all. We picked a figure in the middle of that range and print it so your result is reproducible and you can disagree with it on purpose.
Width always means cheekbone width here, on every page, in every ratio. That consistency matters more than the exact number.
Why Two Websites Give You Two Different Answers
If you have checked your face shape on a few sites and been given different labels, you are not doing it wrong. The guides genuinely disagree, and there are three separate reasons.
They measure the forehead in different places. Some guides measure across the widest part of the forehead near the hairline. Others measure roughly halfway between the eyebrows and the hairline, which is a narrower point on most faces. The same face gives two different forehead numbers depending on which instruction you followed, and that alone can flip a result between oval and diamond.
They use different thresholds. One guide says the cheekbones should be 5 to 10 percent wider than the forehead and jaw. Another says 10 percent or more. Plenty give no number at all and just say noticeably wider, which quietly hands the decision back to you.
Most guides never publish their method. They describe the shape in words, show a diagram, and let you guess.
Diamond, Heart or Oval: The Three Way Confusion
These three get mixed up constantly, and the reason is structural rather than mysterious. Diamond shares its pointed chin with heart, and shares cheekbone led width with oval. Look at only the shared feature and any of the three can look like any other. Each pair has exactly one check that separates it.
-
DiamondCheekbones clearly widest. Forehead and jaw both drop away sharply.Deciding check: forehead well under cheekbones
-
HeartSame pointed chin, but the forehead is the widest part of the face.Deciding check: forehead beats cheekbones
-
OvalAlso cheekbone led, but the taper is gradual and the outline reads smooth.Deciding check: forehead within a few percent
| Feature | Diamond | Heart | Oval |
|---|---|---|---|
| Widest point | Cheekbones, clearly | Forehead | Cheekbones, gently |
| Forehead | Narrow, temples angle in | The widest part of the face | Close behind the cheekbones |
| Chin | Pointed | Pointed | Softly rounded |
| Overall read | Angular, sculpted | Top heavy, tapering down | Smooth, evenly balanced |
If the jaw holds its width most of the way down to the chin instead of tapering, you are not looking at a diamond at all. That is a square or an oblong, depending on how long the face is.
How to Tell Without a Photo
Pull your hair fully back first. People skip this step, and it ruins the result more often than anything else, because the diamond call depends entirely on comparing your forehead to your cheekbones.
The finger test, thirty seconds
Stand square to a mirror in even light. Place two fingers at the widest point of your cheekbones, just below the outer corners of your eyes. Hold that width in mind. Now move to your temples. Then to the angles of your jaw, just below your ears. On a diamond face the cheekbone position is clearly widest, and both other positions come in noticeably narrower.
The measured test
| Measurement | Where to measure | Diamond signature |
|---|---|---|
| Face length | Hairline centre, straight down to the bottom of the chin | 1.35 to 1.55 times cheekbone width |
| Forehead width | Widest point across the forehead | At least 8 percent under cheekbone width |
| Cheekbone width | Arch to arch at the widest point | The largest of the three widths |
| Jaw width | Jaw angle to jaw angle, below the ears | At least 8 percent under cheekbone width |
Divide your cheekbone width by your forehead width. Then divide it by your jaw width. If both answers are 1.08 or higher, you are in diamond territory.
Diamond Face Shape Style Guide
Every choice below follows one principle: add width where the face is narrow, and let the cheekbones be a feature rather than something to hide. Volume at the forehead and at the jaw balances the shape. Anything that narrows those two areas exaggerates it.
The avoid lists matter as much as the recommendations, and almost nobody publishes them. Knowing that a slicked back style works against your proportions is more useful than another list of cuts to consider. All of it is guidance drawn from standard hairdressing, optical dispensing and tailoring practice, not rules.
Hair
- Side swept fringe or curtain bangs to widen the narrow forehead
- Chin length bob with layers building width exactly at the narrow jaw
- Waves starting below the cheekbones so volume lands where it helps
- Deep side part which softens the forehead and breaks the symmetry
- Slicked back styles that expose the narrow temples completely
- Blunt cuts landing at the cheekbone, a line across the widest point
- Very tight ponytails and buns that strip all forehead width
Glasses
- Browline frames adding visual weight across the narrow forehead
- Cat eye shapes that lift attention up and outward
- Oval and round frames to soften the angular cheekbone line
- Detailing on the temple arms to add width at the sides
- Frames wider than your cheekbones, which emphasise the widest point
- Narrow rectangular styles that shrink the upper face further
- Heavy bottom rims dragging weight toward the pointed chin
Beard
- Full beard kept wider at the jaw to square off the lower face
- Boxed beard with a defined edge for structure at the chin
- Fuller cheek growth which softens the cheekbone angle
- Medium stubble as the low maintenance version
- Pointed goatee, which sharpens a chin that is already pointed
- Chinstrap tracing the narrow jaw without adding width
- Very high cheek lines that shrink the beard away from the jaw
Makeup
- Highlighter on the forehead and chin to bring narrow areas forward
- Soft blush below the cheekbone, blended outward
- Fuller, slightly extended brows which widen the upper face
- Lip colour defined at the corners to add lower face width
- Heavy contour under the cheekbones, deepening the angle
- Blush on the cheekbone apex, pushing the widest point wider
- Thin, tightly arched brows that narrow the forehead visually
Outfits and necklines
- Boat neck and wide scoop necklines to add width below the chin
- Collared shirts worn open, framing the jaw with structure
- Earrings with volume at the bottom to widen the lower face
- Structured shoulders balancing the sculpted upper face
- Deep V necklines repeating and extending the downward point
- Tight turtlenecks compressing the already narrow jaw
- Long thin drop earrings which elongate rather than widen
- Halter necks pulling everything inward at the neckline
What This Detector Can and Cannot Do
The landmark detection is precise. The face length is not, and here is exactly why.
The AI model has no hairline landmark. It tracks skin and bone, not hair, so its highest forehead point sits below where your hair actually starts. Every classical face shape method measures length from the hairline. If a tool used the raw landmark, every face would come out shorter than it is and every ratio would land too low.
We apply a fixed correction factor that extends the top point upward toward an estimated hairline. That is a reasonable approximation, not a measurement. Your length figure carries a small margin, and your ratio can shift slightly between photos. We would rather say that than imply lab precision.
Three other things move the numbers: camera angle, head tilt, and lens type. Selfie lenses are wide angle and stretch the centre of the face, which inflates the cheekbone reading and can push an oval result toward diamond. For the most consistent result, use a straight on photo at eye level from three to five feet away, taken with the back camera, hair fully back, neutral expression.
The Measurements tab exists for this reason. Measure with a tape and you choose the hairline point yourself, and no estimation is involved anywhere in the calculation.
Diamond Face Shape: Questions People Actually Ask
What is a diamond face shape?
A diamond face shape is one where the cheekbones are the widest part of the face, with both the forehead and the jaw measurably narrower, and a chin that tapers to a point. The outline is wide in the middle and narrow at both ends. On this site the threshold is cheekbone width at least 8 percent greater than both forehead and jaw width.
How do I know if I have a diamond face shape?
Pull your hair fully back and measure four things: face length from hairline to chin, forehead width, cheekbone width across the widest point, and jaw width at the angle. If your cheekbone measurement is the largest and beats both the forehead and the jaw by roughly 8 percent or more, and your chin narrows to a point, that is a diamond. The detector on this page does all four measurements automatically from a photo.
What is the difference between a diamond and a heart face shape?
Both share a pointed chin, which is why they are confused so often. The difference is the forehead. On a heart face the forehead is the widest part of the face. On a diamond face the forehead is narrower than the cheekbones, often noticeably so, and the temples angle inward before the hairline.
What is the difference between a diamond and an oval face shape?
Both are cheekbone led. On an oval face the width tapers gradually and the forehead sits fairly close behind the cheekbones. On a diamond face both the forehead and the jaw drop away sharply, so the face reads angular rather than smooth. If your forehead measurement is within a few percent of your cheekbones, you are looking at an oval.
Is a diamond face shape rare?
It is commonly described as one of the less common shapes, but there is no reliable published population study giving exact percentages for face shape distribution. Any site quoting a precise figure is estimating. What can be said plainly is that diamond is easy to confuse with heart and with oval, because it shares one defining feature with each of them.
What hairstyles suit a diamond face shape?
Styles that add width where the face is narrow. Side swept fringes and curtain bangs widen the forehead, and chin length bobs, waves and layers that start below the cheekbones add width at the jaw. Avoid slicked back styles that expose the narrow temples and blunt cuts that land right at the cheekbone.
What glasses suit a diamond face shape?
Frames that add width at the temples and draw attention upward. Browline, cat eye, oval and rimless styles all work well. Avoid narrow rectangular frames and anything that sits wider than your cheekbones, since that emphasises the widest part of your face instead of balancing it.
How accurate is this diamond face shape detector?
The landmark detection is precise, but face length is an estimate. The AI model has no hairline landmark, so the top point is extended by a fixed correction factor toward the estimated hairline. Camera angle, head tilt and lens type also shift readings. Use a straight on photo at eye level, taken with the back camera, for the most consistent result.
Does the detector store my photo?
No. The face landmark model runs inside your browser tab. Your photo is never uploaded, stored or sent to any server. You can confirm this yourself by opening your browser developer tools, switching to the Network tab, and running an analysis. You will see the model file download once and no image upload at any point.
Can I use the detector without a photo?
Yes. The Manual tab accepts four measurements taken with a soft tape: face length, forehead width, cheekbone width and jaw width. Any unit works because only the ratios matter. Manual entry also removes the hairline estimate, because you choose the hairline point yourself.
