Look for a broad upper outline and a noticeably narrower jaw. Check the temples as well as the cheekbones: a pointed chin alone can occur in several shapes.
How to identify a heart face shape
Look straight into a mirror with your hair held loosely away from the sides. Start at the temples and follow the edge down past the cheeks. A heart outline tends to keep more width through the upper part and lose it below the cheeks. The chin may look rounded or pointed; what matters is the change in width along the way. Pulling your hair back tightly can distort the soft skin around the temples, so use a loose band or clips instead.
On a photo, compare three horizontal spans: the temples, the widest part of the cheeks, and the sides of the jaw just above its turn toward the chin. The jaw should look appreciably narrower than the upper spans. The temples can be about as wide as the cheeks or a little narrower. The distinction is the upper face looks broad as a whole. If all the width is concentrated in a single band at the cheeks, put diamond on your shortlist.
Now compare visible face length with cheekbone width. A heart outline can be short or moderately long; length alone is a weak signal here. You may see people describe a heart face as an inverted triangle. Both descriptions emphasize upper width and lower taper, and people use the terms differently. If you are choosing frames or a haircut, your observations about where the face narrows are more useful than settling the terminology.
Do a second check if the forehead seems very wide in a selfie. Hold the camera at eye level and move farther away; crop the image afterward if you need a larger view. Keep the jaw relaxed and compare both sides. A raised lens can enlarge the upper face and make the chin recede. A part, a widow’s peak or a short fringe can also change the visible silhouette without changing the underlying proportions.
Heart vs. diamond and oval
Diamond face shape: Both can have a narrow chin. The deciding clue is the change from cheeks to temples. Diamond usually shows a clearer inward step above the cheekbones as well as below them. Try covering the tip of your chin on the photo and comparing the upper outlines. If the widest band still stands out around the cheeks, explore diamond too.
Oval face shape: Both can narrow toward the chin. Oval usually tapers more gently, so the cheeks, temples and jaw look closer in width. A more noticeable contrast between the upper face and the jaw is the useful heart clue. If you see an even, gradual curve rather than a distinct change below the cheeks, oval may describe the photo better.
Hairstyles for a heart face shape
Chin-length texture for movement near the jaw
A bob with lightly textured ends puts some movement beside the narrowest part of the outline. Try it tucked behind one ear and loose on the other before deciding how much volume you want. If your hair springs up as it dries, ask your stylist to place the ends using its dry length. An endpoint that looks level with the jaw when wet may land at the cheeks once dry.
Side parts and fringe you can test first
A side sweep draws a diagonal across the upper face and can make a broad forehead feel less prominent in the overall look. Make a temporary side part while your hair is damp and see how it settles. A longer fringe is easier to pin back if you prefer an open forehead on some days. For a short cut, a relaxed side-swept top can give you the same effect without committing to bangs.
Long layers that start lower
If you like your length, ask where the shortest layer will sit when styled. A layer that ends below the cheek can bring movement toward the jaw; layers that spring up near the temples will emphasize the upper width. Both effects can look intentional. Show your stylist where you would like the ends to land and how you usually dry your hair rather than asking for a generic heart-face haircut.

Glasses for a heart face shape
Compare a slim oval or rounded rectangle with a bolder browline frame of similar width. A light upper rim lets the top of the face stay visually open; a thicker brow adds definition if you want to highlight that area. Pay attention to where the lower rim ends. Slightly deeper lenses can bring attention downward, provided the frame clears your cheeks when you smile.
Check the bridge before judging the style. Look straight ahead, then look down and turn your head: the frame should sit without sliding or relying on tight temples. Compare two frames using a straight-on photo at the same distance, so lens perspective does not make one look wider. An optician can help assess frame sizing and lens requirements for your prescription.

Celebrity style reference: Reese Witherspoon
For the 2013 Oscars, hairstylist Renato Campora styled Witherspoon’s hair with a side part and waves. Notice how one side stays relatively open while the sweep adds movement on the other. You can test the part and the placement of the wave before changing your haircut. Campora’s interview with Allure 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 you are undecided between heart and diamond, write down which area looks widest before opening the tool. Compare that observation with the estimated temple width and jaw width in the overlay. Hair obscuring the temples is a good reason to retake the photo rather than trust a small difference between scores.
