Face Shapes: All 7, How to Measure Yours, and What Suits Each

Every face-shape system comes down to the same four checks. Which of the three horizontal widths is largest: forehead, cheekbones or jaw? How long is the face compared with its width? Is the jaw corner sharp or rounded? And does the chin come to a point or stay broad? The table below sums up how each shape answers those four questions. The diagram beside it draws all seven on the same base face so you can see that the differences are often small.

Notice that two pairs only differ in one trait. Round and square have the same length-to-width balance and differ only in the jaw corner. Oval and oblong share soft curves and differ mainly in length. Those two pairs produce most of the confusion you will meet online, and they are the reason a single label can be misleading.

Oval. Celebrity hairstylist Paul Labrecque, quoted by TODAY, gives the only numeric definition we found: on an oval face “the length is equal to one and a half times the width.” The Art of Manliness, working with barber Thad Forrester, adds that the forehead is wider than the jawline. Optometrist Dr. Catherine Ong, writing for Zenni, describes “balanced proportions, slightly wider cheekbones, gentle narrowing at the forehead and jaw.” Read the full breakdown on our oval face shape page.

Round. Revlon Professional's guide for salon stylists says “the width and length of the face are equal” and that a round face “has few to no angles.” Optical trade journal Eyecare Business puts it as “full, as wide as it is long, with few angles.” The cheekbones are the widest point and the forehead and jaw are about the same width. Our round face guide covers it in depth.

Square. Matrix, L'Oréal's professional salon brand, says “the length and width of your face are equal,” the same as round. What separates the two is the jaw: Revlon Professional says the edges of a square face are “angular and defined,” and Zenni's optometrist describes forehead, cheekbones and jawline of similar width with a strong jaw.

Oblong. Also called long or rectangle. Matrix: “An oblong shape face is longer than it is wide.” All About Vision, reviewed by an ABOC-certified optician, adds “a long, straight cheek line.” The Art of Manliness sums it up neatly: long like an oval, but with forehead, cheekbones and jaw of similar size like a square. Our oblong face shape page explains where oval ends and oblong begins.

Heart. Labrecque: “Your face is widest at the forehead, narrower at the jawline.” L'Oréal Paris offers a quick test: “If your brows are noticeably wider than your jaw, you have a heart-shaped face.” Opticians sometimes call it a base-up triangle. See the heart-shaped face guide.

Diamond. Labrecque again: “You have wider cheeks with a narrow forehead and jawline.” Barber Matty Conrad, quoted in GQ Middle East, describes it as “widest at the cheekbones, and slightly more narrow at the forehead and chin.” The full diamond face shape guide explains how it differs from oval and heart.

Triangle (pear). Opticians at All About Vision describe a face that “has a narrow forehead and widens at the cheek and chin areas,” and Eyecare Business writes “narrow forehead and full jawline.” Be aware that the word triangle is used for opposite shapes: Matrix groups heart and triangle together as narrow at the chin, while optical guides use triangle for a wide jaw. On FaceCheckup, triangle always means the jaw is wider than the forehead.

You can work out your shape with a mirror, a soft tape measure or a photo. All three compare the same things; they just differ in how precise and repeatable the comparison is. Whichever you use, prepare the same way: hair pulled back off the forehead and away from the jaw, glasses off, a neutral expression with the mouth closed, and even light from the front or a window.

The preparation matters more than the method. Hair over the hairline or jaw hides the outline you are trying to compare, and a hard shadow under the cheekbones moves the apparent edge of the face. A smile widens the lower face and lifts the cheeks, which is why the same person can look round when laughing and oval in a passport photo.

If one app called you heart, another called you triangle and your friends say round, you are not alone: that exact complaint is one of the most-asked face-shape questions on Quora. There are four ordinary reasons for it, and none of them means your face is strange.

First, the shapes are conventions. Real faces are continuous, and many sit close to the line between two neighbouring shapes, so a tool that must pick one label will flip between them when the photo changes slightly. Second, sources define the shapes differently: the oval forehead is wider than the jaw for The Art of Manliness but “slightly narrower” for All About Vision, and triangle means opposite things in salon and optical guides. Third, the photo changes the measurement. Ward and colleagues (2018, JAMA Facial Plastic Surgery) modelled that a camera about 30 cm from the face makes the base of the nose look roughly 30% wider relative to face width than at 1.5 m, and the same perspective effect pulls on every width the shape depends on. A turned or tilted head shrinks one side of the face. Fourth, the landmark models themselves have error: Google's model card for MediaPipe Face Mesh V2 reports an average landmark error of 2.06% to 3.85% of the distance between the eyes depending on region and mode, against 2.56% disagreement between human annotators.

We saw the photo effect on our own test selfie, taken with the head turned about 10 degrees and smiling. Before correcting for the head turn, the left and right halves of the face matched in width by only 72%; after the 3D pose correction they matched by 95%. A shape tool that skips that correction is measuring the angle of your head, not the shape of your face.

Published face-shape guides rarely show how real faces vary, so we calculated it from the US Army's ANSUR II anthropometric survey, a public-domain data set of adults measured with calipers in 2010 to 2012. The measure is the facial index: face length from the top of the nose bridge (sellion) to the chin, divided by the width across the cheekbones, times 100. A higher number means a longer face.

Two things stand out. The average man and the average woman are close together, and the spread inside each group (a standard deviation of about 5 points) is larger than the gap between them. Face length relative to width varies far more from person to person than it does between the sexes, which is why the same seven shapes are used for men and women.

Note that this measure starts at the nose bridge, not the hairline, so the numbers are much lower than the stylists' “one and a half times” rule for oval, which measures from the hairline. Neither is wrong; they measure from different points. That is also why you should never compare a ratio from one tool with a threshold from another.

Once you know your shape, the advice follows one idea: add visual width or height where the face is narrow, and keep bulk away from where it is widest. The table gives the single most useful haircut and glasses rule for each shape from our sourced rulebook. Every haircut rule is a stylist convention and every frame rule is an optician convention, each backed by at least two professional sources. They are habits of the trade, not research findings, so treat them as starting points to try in front of a mirror.

The shapes are the same for everyone, but the advice for men and women sometimes points in opposite directions, and it helps to know where. The biggest split is the fringe. Barbers quoted by GQ Middle East and The Art of Manliness tell men with oval or square faces to avoid a heavy fringe because it shortens the face, while women's stylists at Matrix, TODAY and Huda Beauty recommend fringes for oval and oblong faces. Both are consistent with the same idea; they simply start from different typical lengths of hair.

Men also get a tool women's guides leave out: the beard. Barbers use it to add or remove width at the jaw. A man with a diamond face is told to grow fullness at the chin and lower jaw while keeping the cheeks lighter; a man with an oblong face is told to keep the beard from growing much past the chin so it doesn't add length. Where barbers disagree, as they do over whether a square jaw should be shown off with stubble or softened with a rounded beard, our rulebook lists both options rather than picking one.

On the measurement side, the ANSUR II figures above show men's and women's average length-to-width are close. Width itself differs more: the average cheekbone width in that survey was 142.6 mm for men and 133.8 mm for women. In a small study of 72 Kenyan adults, Virdi, Wertheim and Naini (2019) recorded jaw widths that work out to about 0.80 of cheekbone width in men and 0.74 in women. That is one small sample, so take it as a hint that men's jaws tend to look squarer, not as a rule. For a men-only walk-through, see male face shapes.

The detector at the top of this page runs Google's MediaPipe Face Landmarker in your browser and never uploads the photo. Before it measures anything, a quality check looks for a turned head (it warns past 8 degrees and asks for a retake past 15), a chin tipped up or down, a tilted head, too few pixels between the pupils (it needs at least 60), a close-up that distorts the face, a smile or open mouth, closed eyes, and dark or uneven light. A photo that fails badly (a head turned more than 15°, a chin tipped more than 18°, fewer than 35 pixels between the pupils, eyes closed, or a very dark photo) gets a retake request and no score; the other problems are flagged as warnings.

When the photo passes, switch on the Outline, Widths and Jaw layers. Outline traces the edge of your face, Widths draws the forehead, cheekbone and jaw lines the shape is built from, and Jaw marks the jaw corner and its angle. If a line sits on hair or shadow rather than skin, retake the photo with your hair back and the light in front of you. Then read the two shapes and their percentages. A result like 55% and 40% means you sit between two shapes; a result like 80% and 10% is a clear call. The face shape detector page explains the maths and the reference values in full.

Do three things this week. Take three measurement photos in good light and see whether the top shape holds across all of them; if it flips, you sit between two shapes and should use both guides. Take a screenshot of the Widths layer to your next haircut or eye test so the stylist or optician can see the numbers, not just a label. And try one change from the style map above, such as moving your part, choosing deeper frames or adding a fringe, before committing to a bigger cut.

Then go deeper on your own shape: the guides for oval, oblong, diamond, round and heart-shaped faces each cover haircuts, glasses, brows and photos, with the reasons behind each rule. The FaceCheckup homepage scan also measures symmetry, facial thirds and your eyes if you want the full picture.
