# Face Shape Detector A face shape detector is a tool that measures the length of a face and the width of its forehead, cheekbones and jaw in a photo to estimate whether it is oval, round, square, oblong, heart, diamond or triangle shaped. **Key facts:** $0 - No sign-up - Runs in your browser, nothing uploaded - JPG, PNG, WebP or HEIC up to 15 MB - 7 face shapes - 3-question quiz if you have no photo Updated October 2026 Your photo is measured in your browser and never leaves your device. ## How to use it 1. **Load a front-facing photo:** Choose or take a photo where you look straight at the camera, with your hair off your forehead and your mouth closed. JPG, PNG, WebP and HEIC all work, and the photo is read on your device only. 2. **Check the measured lines:** The detector places 478 points on your face and draws the five measurements it uses: face length, forehead, cheekbone and jaw width, and the jaw angle. Each one is shown as a ratio next to its number. 3. **Read your shape and tips:** You get the closest face shape, how clear the call is, and the next closest shape when it is close. Below it are hairstyles, glasses, necklines and the headshot angle that suit that shape. No photo? Answer three questions instead. ## What is a face shape detector? A face shape detector is a tool that estimates your face shape from a photo by measuring the proportions a stylist would check with a tape measure: how long the face is, and how wide it is at the forehead, the cheekbones and the jaw. Those numbers are compared with the seven shapes stylists use, oval, round, square, oblong, heart, diamond and triangle, and the closest one is your result. This one runs Google's MediaPipe face landmarker in your browser. The model places 478 points on your face; the detector reads five measurements from them, divides every width by your cheekbone width so photo size and distance cancel out, and compares the result with an average face. It shows the lines it measured on your photo, so you can see exactly what the call is based on. ## How to tell your face shape at home You need a soft tape measure, a mirror and your hair pulled back. Take four measurements and write them down. Forehead: across the widest part of your forehead, about halfway between your eyebrows and your hairline. Cheekbones: across the face from the outer point of one cheekbone to the other, just below the outer corners of the eyes. Jaw: straight across from one jaw corner to the other, just below the earlobes. Face length: from the centre of your hairline down to the tip of your chin. Then compare them. If the length is clearly the largest number and the three widths are close to each other, your face is oblong. If the length is only a little more than the cheekbone width and the forehead is slightly wider than the jaw, it is oval. A length close to the cheekbone width points to round (soft jaw) or square (angular jaw). Forehead widest with a narrow chin is heart, cheekbones widest with a narrow forehead and chin is diamond, and jaw widest with a narrower forehead is triangle. No tape measure? Stand square to a mirror and trace the outline of your face on the glass with a washable marker or a bar of soap, then step back and look at the outline. The photo detector above does the same measurements in a few seconds, and the three-question quiz works when you have no photo to hand. ## How to read your result The headline is the closest shape. The bars show how well the three nearest shapes fit compared with each other; they are not a percentage of accuracy. When the top two are almost level the result says so and gives you tips for both, because many faces sit between two shapes, and oval and oblong or round and square are frequent neighbours. Pose matters more than people expect. A head turned to one side narrows the face, a raised or lowered chin changes its length, and an open mouth or a big smile lengthens it. Hair over the forehead hides the hairline the length is measured from, a full beard changes the jawline the model sees, and a phone held very close widens the middle of the face. The detector warns you when it sees a turned head, a tilted chin or an open mouth; a straight-on photo with your hair back, taken from a step away, gives the steadiest answer. - [Take a better photo with your phone](https://www.smartheadshots.ai/guides/how-to-take-a-headshot-with-your-phone) ## Oval face shape: hairstyles, glasses and necklines An oval face is a little longer than it is wide, with a forehead slightly wider than the jaw and a softly rounded chin. Because no single width dominates, it is the shape most styles are measured against. Hairstyles for an oval face: almost anything works, from long layers and a blunt bob to a pixie, curtain bangs or a short textured crop. Glasses: frames about as wide as the widest part of your face, in square, rectangular or geometric shapes. Necklines: crew necks, V-necks and open collars all keep the balance. ## Round face shape: hairstyles, glasses and necklines A round face is about as long as it is wide, with full cheeks, the widest point at the cheekbones and a soft jaw without strong corners. Hairstyles for a round face shape add height and length: layers that fall past the chin, a side part, volume at the crown or a quiff. Chin-length blunt cuts end at the widest point and add width. Glasses: angular frames such as rectangles, squares and wayfarers, slightly wider than the face. Necklines: V-necks and open collars draw a vertical line that lengthens the face. ## Square face shape: hairstyles, glasses and necklines A square face is about as long as it is wide, with a broad forehead and a strong, angular jaw of similar width, so the sides run fairly straight. Hairstyles soften the corners: layers, waves, side-swept bangs, or longer hair on top with tapered sides. Glasses: round and oval frames soften the angles, and rimless or browline frames also work. Necklines: scoop necks, round necklines and soft open collars balance a strong jaw. ## Oblong (rectangle) face shape: hairstyles, glasses and necklines An oblong face, also called rectangle or long, is clearly longer than it is wide, with the forehead, cheekbones and jaw all of similar width. Hairstyles add width rather than height: chin-to-shoulder lengths, waves, a fringe or curtain bangs, and fuller sides, while tall styles on top add more length. Glasses: deep, oversized or round frames break up the length, and a strong brow line helps. Necklines: crew necks, boat necks and turtlenecks add width; deep V-necks add length. ## Heart face shape: hairstyles, glasses and necklines A heart-shaped face is widest at the forehead and narrows through the cheeks to a slim or pointed chin. Some people with a heart shape also have a widow's peak at the hairline. Hairstyles add fullness at the jaw: chin-length bobs, side-swept bangs, layers that start at the chin, or a side part. Glasses: bottom-heavy, oval and rimless frames balance a wider brow, while heavy top-line frames add to it. Necklines: scoop, sweetheart and boat necklines add width below the chin. ## Diamond face shape: hairstyles, glasses and necklines A diamond face is widest at the cheekbones, with a narrower forehead and a narrow, defined chin, so the outline comes to a soft point at the top and the bottom. Hairstyles add width at the forehead and chin: a fringe, side-swept bangs, chin-length bobs or fuller styles at the temples. Glasses: oval, cat-eye and rimless frames, or frames with a strong brow line, balance the cheekbones. Necklines: V-necks and scoop necks work well, and very high collars narrow the chin further. ## Triangle face shape: hairstyles, glasses and necklines A triangle face, also called pear shaped, is widest at the jaw and narrower at the forehead. Hairstyles add volume at the crown and temples: layers on top, a side part or a longer fringe, without bulk at jaw level. Glasses: frames wider at the top, such as browline, cat-eye or aviator shapes. Necklines: V-necks and open collars draw the eye down the centre rather than across the jaw. ## Best headshot angles for your face shape Your face shape also tells you how to stand for a headshot. Three things do most of the work: the camera height, the turn of your head and the crop. A camera at eye level shows your proportions as they are; a camera a touch above eye level shortens the lower face and puts the focus on the eyes; a camera below eye level lengthens the jaw and widens the forehead. Round and triangle faces gain definition from a camera slightly above eye level and a small turn to one side; bringing the chin forward and a little down sharpens the jawline. Square faces soften with a three-quarter turn and a slight head tilt. Oblong faces look best with the camera exactly at eye level and a slightly wider crop that includes the shoulders. Heart faces suit a camera at or just below eye level so the forehead does not dominate, and diamond faces suit a three-quarter turn that shows the cheekbones. Oval faces can take almost any angle; a slight three-quarter turn at eye level is the safe default. For the crop, keep your eyes about a third of the way down the frame and leave a little space above your head. On LinkedIn and most work apps the photo is shown as a small circle, so a head-and-shoulders crop with the face centred reads best. - [See headshot poses that work](https://www.smartheadshots.ai/guides/headshot-poses) - [Crop your photo for LinkedIn](https://www.smartheadshots.ai/tools/profile-photo-cropper) ## Using your face shape for LinkedIn, resume and dating photos On LinkedIn, a company page or a resume, the goal is a photo that looks like you on a good day: camera at the height your face shape suits, a neckline that balances it, and a plain background. Your necklines tip is the quickest win, because a collar or neckline sits right at the edge of a head-and-shoulders crop. For dating profiles the same angles apply, with more room for a natural smile and a looser crop. Whichever platform you shoot for, check the photo for sharpness, light and framing before you upload it. - [What to wear for a headshot](https://www.smartheadshots.ai/guides/what-to-wear-headshot) - [Check your photo for free](https://www.smartheadshots.ai/tools/headshot-photo-checker) ## What happens to your photo Nothing leaves your device. The photo is decoded and measured in your browser; the only downloads are the face model and its runtime, fetched from public hosts the first time you use the tool. Reloading the page clears the photo, and the result is never stored or shared. The detector measures proportions only. It does not rate how you look, guess your age or identify you. ## Face shapes at a glance | Face shape | Proportions | Hairstyles | Glasses | Headshot angle | | --- | --- | --- | --- | --- | | Oval | A little longer than wide, forehead slightly wider than the jaw, soft chin | Almost any: layers, bob, pixie, curtain bangs | Square, rectangular, geometric | Eye level, slight three-quarter turn | | Round | About as long as wide, widest at the cheeks, soft jaw | Height and length: long layers, side part, volume on top | Rectangular, square, wayfarer | A touch above eye level, small turn, chin forward | | Square | About as long as wide, forehead and jaw of similar width, angular jaw | Soft texture: layers, waves, side-swept bangs | Round, oval, rimless | Three-quarter turn with a slight tilt | | Oblong | Clearly longer than wide, straight sides | Width at the sides: waves, fringe, chin-to-shoulder length | Deep, oversized, round | Exactly at eye level, wider crop | | Heart | Widest at the forehead, narrow or pointed chin | Fullness at the jaw: chin-length bob, side bangs | Bottom-heavy, oval, rimless | At or just below eye level, small turn | | Diamond | Widest at the cheekbones, narrow forehead and chin | Width at forehead and chin: fringe, chin-length bob | Oval, cat-eye, strong brow line | Three-quarter turn, soft front light | | Triangle | Widest at the jaw, narrower forehead | Volume at the crown and temples | Browline, cat-eye, aviator | A touch above eye level, slight turn | ## FAQ ### What is my face shape? Your face shape is the outline your forehead, cheekbones, jaw and face length make together, and stylists sort it into oval, round, square, oblong, heart, diamond or triangle. The quickest way to find yours is to load a front-facing photo into the detector above, which measures those proportions in your browser. Without a photo, the three-question quiz or a tape measure and a mirror work too. ### How do I tell my face shape? Measure four things with a soft tape: forehead width, cheekbone width, jaw width and the length from hairline to chin. Then compare them: the largest measurement and the shape of your jaw decide the shape. For example, a length close to the cheekbone width with a soft jaw is round, while a forehead wider than a narrow chin is heart. ### How accurate is a face shape detector? It is a good estimate, not a diagnosis. Face shapes are a stylist's system with fuzzy borders, so two people, or two tools, can disagree on a face that sits between two shapes. This detector shows the measured lines, the closest shapes and how close the call was, and it warns you when a turned head, a tilted chin or an open mouth may have skewed the result. ### What hairstyle suits my face shape? The rule of thumb is to add volume where your face is narrow and keep it away from where it is widest. Round faces gain from height and length, oblong faces from width at the sides, heart faces from fullness at the jaw, and square faces from soft layers and waves. Oval faces suit most cuts. ### What glasses suit my face? Frames usually work best when they contrast with your face shape. Angular frames add structure to round faces, round and oval frames soften square faces, deep or oversized frames shorten oblong faces, and bottom-heavy or rimless frames balance heart faces. Choose frames about as wide as the widest part of your face. ### Can your face shape change over time? Yes, to a degree. Bone structure is set in adulthood, but weight changes and ageing shift the soft tissue around the cheeks and jaw, which can move a face toward a neighbouring shape. If your weight has changed noticeably, measure again. ### Does face shape matter for a headshot? It helps you choose the camera height, head turn and crop. A camera slightly above eye level and a small turn define a round face, a three-quarter turn softens a square jaw, and eye level with a wider crop keeps an oblong face from looking long. Your face shape tips above include the headshot angle for your shape. ### Is my photo uploaded? No. The photo is decoded and measured in your browser, and only the face model is downloaded to your device. Nothing is sent to our servers, and reloading the page clears the photo. ## More free tools - [LinkedIn Photo Checker](https://www.smartheadshots.ai/tools/headshot-photo-checker): A LinkedIn photo checker is a tool that scores a profile picture out of 100 for light, sharpness, framing, eye line and background, rating the photo rather than the person in it. - [Circle Crop Tool](https://www.smartheadshots.ai/tools/profile-photo-cropper): A circle crop tool cuts a photo into a round profile picture and saves it as a PNG with transparent corners, or as a square sized for each platform. - [Background Changer](https://www.smartheadshots.ai/tools/headshot-background-changer): A headshot background changer is a tool that separates the person in a portrait from the background behind them and replaces that background with plain white, grey, a brand color or a blurred version of the original. - [Cost Calculator](https://www.smartheadshots.ai/tools/headshot-cost-calculator): A headshot cost calculator estimates what professional headshots cost from a studio photographer, an on-site corporate photographer or an AI headshot service, using published prices for your city, team size, looks and retouching. - [Headshot Prompt Generator](https://www.smartheadshots.ai/tools/ai-headshot-prompt-generator): An AI headshot prompt generator builds a ready-to-paste prompt that asks ChatGPT, Gemini or another image tool to turn your own photo into a professional headshot while keeping your face unchanged. - [Profile Picture Tester](https://www.smartheadshots.ai/tools/profile-picture-tester): A profile picture tester, or pfp tester, previews your photo as the round or rounded square avatar that LinkedIn, Slack, Microsoft Teams, Gmail, Zoom and X show, from the large profile view down to the small icons beside comments and chat messages. - [Background Picker](https://www.smartheadshots.ai/tools/headshot-backgrounds): A headshot background picker shows which professional backgrounds suit each industry and a LinkedIn photo, with examples, color codes and the attire that pairs with each one. - [Color Analysis Quiz](https://www.smartheadshots.ai/tools/color-analysis): A color analysis quiz is a short set of questions about your undertone, hair, eyes and contrast that sorts you into a seasonal color type and shows which colors flatter you. - [LinkedIn Profile Checker](https://www.smartheadshots.ai/tools/linkedin-profile-checker): A LinkedIn profile checker is a tool that scores your headline, About section and profile photo against clear rules, such as LinkedIn's character limits, an opening line that lands before "see more" and a way to contact you. ## Related headshot packs - [Professional Headshots](https://www.smartheadshots.ai/professional-headshots): A professional headshot is a head and shoulders portrait, evenly lit against a plain or softly blurred background, used to represent you on company websites, staff directories, email signatures, conference programs and press coverage. - [LinkedIn Headshots](https://www.smartheadshots.ai/linkedin-headshots): A LinkedIn headshot is a head and shoulders portrait, framed for the circle crop LinkedIn applies, that represents you on your profile, in recruiter search results and beside every message and comment you post. - [Dating Profiles](https://www.smartheadshots.ai/dating-profile-photos): A dating profile picture is a clear, recent photo of your face in good light, with your eyes visible and nobody else in the frame, that leads your profile on apps such as Hinge, Bumble and Tinder. ## Links - [Create your headshots](https://www.smartheadshots.ai/start) - [All free tools](https://www.smartheadshots.ai/tools) - [Home](https://www.smartheadshots.ai/)
