Use the face shape calculatorIn short
- Your face shape comes from four measurements: face length, cheekbone width, forehead width and jaw width.
- Compare them as ratios to find the closest of seven shapes: oval, round, square, heart, diamond, triangle or oblong.
- Photo-based auto-detection is unreliable, so measuring yourself gives a better answer.
- Use shape as a starting point for haircuts and glasses, not as a rule.
"What face shape do I have?" is one of the most common questions people ask before a haircut or before buying glasses. Stylists use face shape as a starting point, and a face shape calculator can turn a few measurements into a clear answer. This guide shows how to find your face shape at home, what the seven shapes are and what each usually suits.
If you would rather measure and get an instant answer, use the free face shape calculator. Read on to understand what it is doing.
What is a face shape?
Your face shape is the outline of your face, described by the proportions of your face length, cheekbones, forehead and jaw. It is a simplified category. Real faces vary continuously, so many people fall between two shapes.
How to find your face shape at home
You need a mirror and a soft tape measure, or a straight-on photo and a screen ruler. Pull your hair back and relax your face.
- Face length: from the middle of the hairline to the bottom of the chin.
- Cheekbone width: across the widest part of the cheekbones, just below the outer corners of the eyes.
- Forehead width: across the forehead, between the temples, at its widest.
- Jaw width: across the jaw at the angle just below each ear.
Use the same unit for all four. The comparison uses ratios, so centimeters, inches and pixels on a photo all work. Then enter them into the face shape calculator.
Quick chart: the seven face shapes
| Shape | Widest part | Chin and jaw | Length compared with width |
|---|---|---|---|
| Oval | Cheekbones or forehead, slightly | Softly rounded | About 1.5 times |
| Round | Cheeks | Soft, rounded | Close to equal |
| Square | Forehead, cheeks and jaw similar | Strong, angular | Slightly longer than wide |
| Heart | Forehead | Narrow, pointed | Medium |
| Diamond | Cheekbones | Narrow forehead and jaw | Medium to long |
| Triangle | Jaw | Broad jaw | Medium |
| Oblong | Forehead, cheeks and jaw similar | Straight, long | 1.5 times or more |
The seven shapes in detail
Oval
The length is about one and a half times the width, with a forehead slightly wider than the jaw and a softly rounded chin. It is often called the most balanced shape, so few styles are off limits. Layers, side parts and soft fringes all work, and most frames suit.
Round
Length and width are close, with soft cheeks and a rounded jaw. Height and length in a haircut add definition, such as layers past the chin or volume at the crown. Angular or rectangular frames balance the curves.
Square
Forehead, cheeks and jaw are similar in width, and the jaw is strong. Soft layers, waves and side-swept fringes soften the angles. Round or oval frames balance a strong jaw.
Heart
The forehead is widest and the face tapers to a narrower chin. Chin-length cuts, side-swept fringes and volume around the jaw balance the top. Light, bottom-heavy or round frames work well.
Diamond
The cheekbones are widest, with a narrower forehead and jaw. Volume at the forehead and jaw balances prominent cheekbones. Oval and cat-eye frames highlight them.
Triangle
The jaw is widest, with a narrower forehead and cheekbones. Volume at the crown and temples balances a strong jaw. Frames that are heavier at the top, such as browline styles, balance it too.
Oblong
The face is noticeably longer than it is wide. Fringes and width at the sides shorten the look, and wide, deeper frames add width. Very long, flat hair and extra height on top can lengthen the face further.
Heart vs diamond face shape: how to tell
Both taper to a narrower chin, so they are easy to confuse. The difference is where the widest point sits. If your forehead is your widest part, you lean heart. If your cheekbones are the widest and your forehead is narrower, you lean diamond.
How to tell if my face is oval or round
Compare the length with the width. If your face is clearly longer than it is wide, you lean oval. If the two are close and your cheeks are full, you lean round.
How to measure face shape at home
To measure face shape at home, sit in front of a mirror or take a straight-on photo, pull your hair back and relax your face. With a soft tape or a screen ruler, measure the four distances in the same unit. Take each measurement twice and use the average, because small slips change ratios. Measure the widest point of the forehead, cheekbones and jaw rather than a guess, and keep your head level. If you use a photo, make sure the camera is at eye level and the face is not tilted.
Face shape calculator from photo: how to measure on a picture
A face shape calculator from a photo needs the same four measurements, only taken on a screen. Open a straight-on photo, zoom in and mark the four distances with any ruler or measurement tool, using pixels. Because the calculator compares ratios, pixels work as well as centimeters. Avoid photos with a tilted head, a wide lens or a big smile, which change the widths. Then enter the numbers into the face shape calculator.
Best haircut for each face shape
Stylists talk about balance: the aim is to soften strong angles and add width or length where the face has less. In short, oval faces suit most cuts, round faces suit length and height, square faces suit soft layers and waves, heart faces suit chin-length cuts and side fringes, diamond faces suit volume at the forehead and jaw, triangle faces suit volume at the crown and temples, and oblong faces suit fringes and side volume. Treat these as starting points and bring a photo to your stylist.
Best glasses for each face shape
For glasses, the same idea applies. Choose frames that contrast with your face shape: angular frames for round faces, round or oval frames for square faces, bottom-heavy or rimless frames for heart faces, cat-eye or oval frames for diamond faces, top-heavy frames for triangle faces and wide, deeper frames for oblong faces. Oval faces can wear most styles. The best test is to try frames on in a mirror and pick the ones that feel like you.
Best haircut and glasses by shape: summary table
| Shape | Haircut ideas | Glasses ideas |
|---|---|---|
| Oval | Most cuts; layers, side part | Most frames |
| Round | Height, long layers | Angular, rectangular |
| Square | Soft layers, waves | Round, oval |
| Heart | Chin-length, side fringe | Bottom-heavy, rimless |
| Diamond | Volume at forehead and jaw | Oval, cat-eye |
| Triangle | Volume at crown and temples | Browline, top-heavy |
| Oblong | Fringes, side volume | Wide, deep frames |
Why the calculator asks for measurements
You may wonder why a face shape tool does not simply detect your shape from a selfie. The landmark models that run in a browser pull every face toward an average outline, so they cannot tell shapes apart reliably. In our own tests on several faces, the ratios came out almost identical. Four honest measurements beat a confident wrong answer. We explain this on the face shape page too.
Face shape is a guide, not a rule
Nobody has to follow shape-based advice. Hair texture, lifestyle and taste matter more, and trends change. Treat your shape as a helpful starting point for a haircut conversation or a glasses shortlist.
Combine it with other tools
If you enjoy learning from a photo, the Face Balance tool measures symmetry and proportions, Color Match finds your best colors and the face age calculator estimates how old you look. For context on symmetry, read facial symmetry: what scores really mean, and for colors read personal color analysis at home.
The takeaway
To find your face shape at home, measure face length, cheekbones, forehead and jaw, compare them as ratios and pick the closest of the seven shapes. Use it as a starting point for hair and glasses, and try the face shape calculator for an instant result.
