What Is My Face Shape? A Complete Guide to the 6 Face Shapes

Knowing your face shape is the single most useful thing you can learn about styling your appearance. It drives decisions about haircuts, glasses, beard styles, makeup contouring, and even which collars suit you. The good news is that identifying it only takes a few measurements — and you can now get an instant read from a photo.

Why face shape matters

Every styling choice sits on top of your underlying facial geometry. A haircut that frames an oval face beautifully can fight against a square one. Glasses that balance a round face may overwhelm a narrow one. Once you know your base shape, you stop guessing and start choosing.

The shapes people usually refer to are these six: oval, round, square, heart, oblong (or long), and diamond. Most faces are a blend of two, so the goal is to find the dominant one.

How to measure your face at home

You only need a soft measuring tape, a mirror, and a few quiet minutes. Take four measurements in centimeters:

• Forehead width — across the widest point of your forehead, roughly midway between your brows and hairline.
• Cheekbone width — across the cheekbones at their widest point, just under the outer corner of each eye.
• Jawline width — from the tip of your chin to the angle of your jaw, then doubled.
• Face length — from the center of your hairline to the tip of your chin.

Then compare them against the shape signatures below.

The six face shapes at a glance

Oval. The face is about one and a half times longer than it is wide, and the jawline is softly rounded. Forehead, cheekbones, and jaw are close to equal width. This is the most balanced shape, which is why so many styles are designed with it in mind.

Round. Width and length are nearly the same, with full cheeks and a rounded jaw. The cheekbones are usually the widest point, and there is little visible angle at the jaw.

Square. A strong, angular jaw that is roughly as wide as the forehead, with a straight hairline. The defining trait is that the jaw angle is sharp rather than curved.

Heart. A broad forehead and cheekbones that taper to a narrow, pointed chin. This is the inverse of the triangle — the emphasis is on the top of the face.

Oblong (long). Longer than it is wide, with the forehead, cheekbones, and jawline similar in width. The face is stretched vertically, so the goal of styling is usually to add width.

Diamond. Narrow forehead and chin with cheekbones that are clearly the widest point. The high, prominent cheekbones are the signature feature.

A quicker way: measure the ratios

You do not have to eyeball it. The reliable shortcut is comparing your face length to your face width:

• Length noticeably greater than width → oblong
• Length and width nearly equal, rounded jaw → round
• Length and width nearly equal, angular jaw → square
• Width greatest at the cheekbones, narrow chin and forehead → diamond
• Broad forehead and cheekbones narrowing to a pointed chin → heart
• Length about 1.5× width with balanced features → oval

These are exactly the ratios a face shape detector measures automatically, so they translate directly to the tool.

Test it with AI instead of a measuring tape

If you would rather not measure by hand — or you want a second opinion — you can upload a front-facing photo and get your shape identified instantly. The Face Shape Detector reads your proportions and maps them to the closest shape, with no signup required.

For a deeper picture of your proportions, the Facial Ratios Calculator breaks down the key ratios across your face, and the Golden Ratio Face Calculator compares your proportions to the classic aesthetic ratio. Taken together, they give you a far richer view of your facial geometry than any single shape label.

What to do next

Once you know your shape, three things open up:

1. Hair. Your shape points you to framing styles that add length, width, or balance.
2. Eyewear. Contrast shapes tend to flatter — angular frames for round faces, rounder frames for square faces.
3. Contouring. Light and shadow placement follows your cheekbones and jawline.

Knowing your face shape is not about chasing a single "ideal." It is about giving you a starting point so your styling choices work with your natural structure instead of against it.
