Check for narrowing in both directions from the cheeks. A narrow chin paired with a broad upper face may point toward heart instead.
How to identify a diamond face shape
Look for the widest part of your outline in a level, straight-on view. Diamond usually places this span around the cheekbones. Then move your attention up toward the temples and down toward the jaw. The outline should pull inward in both directions, rather than staying about as wide above the cheeks as it does at the cheeks. Make sure you are comparing the sides of the face and excluding the ears or hair from the width.
The forehead comparison is often the deciding step. Tuck or clip hair away from the temples without stretching the skin. Look at the sides near the brow and above the outer cheeks. A narrow strip of visible forehead between two pieces of hair does not establish that the upper face is narrow. The tool uses temple landmarks as an estimate, so a fringe or heavy shadows can make this distinction less reliable even when you can see the cheeks clearly.
Next compare the jaw width with cheekbone width. The diamond pattern usually includes a lower face that narrows noticeably below the cheeks. The chin may be pointed, but it can also have a softer tip. A prominent cheekbone highlight or hollow shadow is not the same thing as width. Try diffused light from the front and look at the actual outer edge rather than following makeup, highlights or cheek contours inside the face.
Face length can be moderate or more pronounced. A long photo is not enough to pick diamond: you still need the difference between cheek width and the spans above and below. Compare two shots at eye level if your first one exaggerates the cheeks. Move farther from the lens, keep your face centered, and check whether the width pattern persists. If it changes when you tilt or turn, prioritize the straight view.
Diamond vs. heart and oval
Heart face shape: Both can narrow toward the chin. The temples are the key comparison. In heart, the upper area keeps more of the width seen across the cheeks. In diamond, there is a more distinct narrowing above the cheekbones. Hide the chin on a copy of the photo and compare the top half alone if a pointed chin keeps drawing your eye.
Oval face shape: The cheekbones can be the widest point in both. With oval the transition to the temples and jaw tends to be gradual, and the widths are closer together. Diamond shows a stronger peak at the cheeks. If the difference is subtle, check whether you actually see a change of outline or just a brighter patch of light on the cheek.
Hairstyles for a diamond face shape
Keep cheekbones visible with a light fringe
An open curtain fringe or a light side sweep can add movement near the temples without hiding the cheeks. Clip a front piece to roughly the length you are considering and see where it falls after you move your head. Ask for longer ends if you want to tuck the pieces behind your ears. A fringe that curves outward near the temples reads differently from one that ends at the broadest part of the cheeks.
Try a bob that gives the jaw some movement
With a narrow lower face, textured ends near or below the chin can bring attention to the jaw. A tucked side can leave one cheekbone exposed. If you wear curls or waves, decide how much width you want the dry shape to have at its ends. A cut that is fuller right at cheek level can highlight the widest point instead, which may be exactly the look you want.
Use a short cut or pulled-back style to show the outline
A short crop with a little texture over the temples gives a different outline from a very tight side cut. If you like a pulled-back look, try changing only the part or loosening the hair near the temples before cutting. Take two photos from the same distance so you can see whether you prefer a fuller upper silhouette or the stronger cheekbone emphasis of a slick finish.

Glasses for a diamond face shape
Try a light browline frame or a soft cat-eye if you want the upper rim to draw attention upward. An oval shape can follow the transition from cheek to jaw without introducing more angles. Keep the size consistent while comparing. A narrow top rim may feel smaller even when the temples fit, while a pronounced outer corner can create more visible width at the brow.
Check how the frame sits where the cheekbones project most. Smile, look down and view the frame from the side: the lower rim should not lift or rock when your cheeks move. A frame with a different bridge height or adjustable pads can change the clearance. Choose a size that fits before deciding whether you want a bolder top edge or a lighter outline.

Celebrity style reference: Zendaya
Zendaya’s hairstylist Larry Sims described her close pixie look at the 2015 Grammys in Allure’s retrospective. The small amount of hair beside the cheeks makes the outline easy to see. Use it as a reference if you want your haircut to reveal that area; study the cut and placement rather than trying to copy the exact silhouette. Sims’s comments and the event photo shows the look. Use the styling detail as inspiration; a red carpet photo is a poor reference for measuring someone’s face.
Check your own outline
If the cheeks look widest but the temple estimate seems uncertain, make a fresh photo with both temples visible and compare the overlay with your first image. A similar diamond and heart score is a reason to read both guides. The style ideas are still useful even when the shape label remains mixed.
