Want to know your face shape? Upload a selfie and get your result.
Upload a selfie and our AI Face Shape Detector classifies your face shape in 30 seconds — oval, round, square, heart, diamond, or oblong — with the measurements behind the answer and matching hairstyle and glasses recommendations.
Forget the mirror-and-marker face shape quiz. The detector maps your facial landmarks, measures forehead width, cheekbone width, jawline length, and face length, then matches the ratios to a face shape category — the same approach stylists use, run in seconds from a single photo.
The AI Face Shape Detector classifies your face into one of six categories: oval, round, square, heart, diamond, or oblong. Edge cases (square-leaning oval, heart-leaning diamond) get a confidence score so you know how clean the read is.
Your face shape result comes with hairstyles, glasses frames, brow shapes, beard styles (men), and contouring tips (makeup) that balance your proportions — not generic advice, just what works for your specific shape.
Upload a front-facing photo, get your face shape back in 30 seconds with the underlying measurements. No quiz to fill out, no account required for the first scan.
USE CASES
Drop in a front-facing photo and the face shape detector returns your category — oval, round, square, heart, diamond, or oblong — with the underlying facial measurements behind the answer.
Curtain bangs lengthen a round face. Side parts soften a square jaw. Layered bobs balance a heart-shaped face. Every result includes hairstyle recommendations that flatter your specific face shape — for men and women.
Round faces work better with angular frames; square faces with round or oval frames; heart-shaped faces with wider bottoms. The detector tells you which eyewear styles match your face shape before you spend money on the wrong pair.
Contouring placement depends entirely on your face shape — oblong faces want horizontal width, round faces want vertical length. Get a map of where to highlight and where to shade based on your detected proportions.
Square faces look great with shorter, tighter beards. Round faces want length at the chin. Oblong faces benefit from fuller sides. The face shape detector pairs each shape with beard recommendations that balance the silhouette.
Stopped halfway through a face shape quiz because you couldn't tell if your jawline is square or rounded? The AI does the measuring for you. Upload one photo and get an answer with a confidence score — no ruler, no guessing.
Upload a selfie and our AI Face Shape Detector returns your face shape plus matching hairstyle and glasses recommendations in 30 seconds.

An AI Face Shape Detector is an online tool that classifies your face shape from a single photo. It uses a computer-vision model to find facial landmarks — the hairline, cheekbones, jawline corners, and chin — then measures the ratios between them and matches them to one of six face shape categories: oval, round, square, heart, diamond, or oblong. The whole process takes about 30 seconds and returns hairstyle, glasses, and makeup recommendations matched to your shape.
The detector maps facial landmarks on your selfie, then measures four key ratios: forehead width, cheekbone width, jawline width, and face length. The classifier compares those ratios to the geometric patterns that define each face shape — a round face has roughly equal width and length with soft jaw angles; a square face has sharp jaw corners with width and length close to equal; an oval face has length about 1.5x its width with a softer chin. It's the same approach a stylist takes, just measured by the model instead of estimated by eye.
Very accurate for clean, front-facing photos in even lighting — the detection is purely geometric, so the AI Face Shape Detector reads facial landmarks the same way every time. Edge cases (a face that's borderline between oval and oblong, or square-leaning round) get a confidence score so you know how clean the read is. Bad photos — heavy makeup that hides the jawline, low resolution, dramatic angles — reduce accuracy. Use a neutral selfie with your hair pulled back for the most reliable result.
Overchat AI Face Shape Detector is a paid tool. With the Pro subscription, you can run unlimited face shape detections, save your result, and pull up hairstyle and glasses recommendations any time. A free trial lets you try the AI Face Shape Detector once before subscribing.
The 6 main face shapes are oval, round, square, heart, diamond, and oblong (sometimes called rectangle). Oval is roughly 1.5x as long as it is wide with a softly rounded jaw. Round has nearly equal width and length with soft curves. Square has equal width and length with sharp jaw corners. Heart is widest at the forehead and narrowest at the chin. Diamond is widest at the cheekbones with a narrow forehead and chin. Oblong is longer than wide with mostly straight sides.
A front-facing selfie taken straight on, in even daylight, with your hair pulled back so the jawline and hairline are both clearly visible. Avoid filters, heavy contouring makeup, and side-angle shots — the AI is reading the geometry of your face, so anything that hides the outline hurts accuracy. A neutral expression with a closed mouth is best.
Yes — every result comes with hairstyle recommendations matched to your face shape, for both men and women. Round faces benefit from styles that add vertical length (curtain bangs, high tops). Square faces benefit from soft layers and side parts that break up the jaw line. Heart-shaped faces look great with chin-length bobs that add width below the cheekbones. The face shape detector returns 3–5 styles you can save or take to your stylist.
Yes. The general rule is contrast: round faces with angular frames (rectangular, wayfarer); square faces with round or oval frames; oval faces work with almost anything; heart-shaped faces with frames wider at the bottom; diamond faces with cat-eye or oval frames. The AI Face Shape Detector returns specific frame shapes that suit your face shape, so you can shop glasses without guessing.
Both are longer than wide, but oval has softer curves and a slightly tapered chin, while oblong (sometimes called rectangle) is more uniformly straight with parallel sides and a flatter jaw. Oval is the most balanced face shape; oblong tends to want hairstyles that add visual width. The AI Face Shape Detector measures the actual ratios, so it can distinguish a borderline oval from an oblong even when the difference isn't obvious to the eye.
Chinese company Baidu has quietly released a model that's just as good as DeepSeek and ChatGPT — ERNIE 4.5 delivers exceptional performance at a fraction of the cost — and most people outside China have never even heard of it.
If you're wondering: what is DeepSeek AI, the answer is quite simple. DeepSeek AI is a Chinese AI research lab that builds large language models. The company released several models in late 2024 and early 2025 that compete directly with OpenAI's GPT-4 and Anthropic's Claude, but at a fraction of the operating cost.
ChatGPT Plus costs $20 per month plus tax, while the Pro plan costs $200 per month plus tax. Understandably, not everyone is willing to pay that much for a chatbot, especially if the premium features aren’t worth it to them. This raises an obvious question: how can I use ChatGPT for free?
