How to Determine Face Shape

There are three reliable ways to find your face shape: trace it in a mirror, measure it with a tape, or let a detector measure it from a photo. Here is how to determine face shape with each method, and the simple rules that turn your observations into one of the seven shapes.

Use the photo face shape detector Use the calculator

Before you start

Method 1: the mirror trace

This is the quickest method and needs only a mirror and a washable marker, lipstick or soap.

  1. Stand about 30 cm (one foot) from a mirror, keep your head still and close one eye.
  2. Trace the outline of your face on the glass, from the hairline around the chin and back up.
  3. Step back and look at the outline. Where is it widest? Is it longer than wide? Are there corners at the jaw?

The trace makes proportions much easier to judge than looking at your face directly, because your eyes are no longer drawn to your features. Its weakness is accuracy: a slight head movement while tracing distorts the outline.

Method 2: measure with a tape

For numbers you can compare, use a soft tape measure and take four measurements:

  1. Forehead: across the widest part, near the temples.
  2. Cheekbones: across the highest points, just below the outer corners of the eyes.
  3. Jaw: from the corner of the jaw below one ear to the same point on the other side.
  4. Face length: from the center of the hairline to the bottom of the chin.

Divide each one by the cheekbone width. Or enter the four numbers in the face shape calculator, which does the math and scores all seven shapes for you.

Method 3: let a detector measure a photo

The face shape detector does the tape-measure method from a photo. It places 478 landmarks on your face, finds your hairline, measures the same four lines plus the angle of your jaw, and shows the lines on your photo so you can check them. It also warns you when the photo is likely to give a wrong reading, for example when your head is turned or your mouth is open. Everything runs in your browser and your photo is never uploaded.

How to determine face shape from your measurements

Work through these questions in order. The first clear answer usually decides the shape.

  1. Is your face length at least 1.6 times your cheekbone width, with forehead, cheekbones and jaw all similar? You have an oblong face.
  2. Is your jaw clearly the widest part, wider than your forehead? You have a triangle face.
  3. Is your forehead the widest part (or equal to the cheekbones), with a much narrower jaw and a narrow chin? You have a heart face.
  4. Are your cheekbones clearly wider than both your forehead and your jaw, with a narrow chin? You have a diamond face.
  5. Is your face length less than about 1.3 times the width? Then check the jaw: angular corners mean square, a soft curve means round.
  6. Otherwise (longer than wide, widest at the cheekbones, soft jaw): you have an oval face.
ShapeQuick description
OvalLonger than wide, widest at the cheekbones, with a softly rounded jaw.
RoundAbout as long as it is wide, widest at the cheeks, with a soft, curved jaw.
SquareForehead, cheekbones and jaw are about the same width, with a strong, angular jaw.
HeartWide forehead and cheekbones that taper to a narrow, often pointed chin.
OblongClearly longer than wide, with forehead, cheekbones and jaw all of similar width.
DiamondWide, prominent cheekbones with a narrower forehead and a narrow chin.
TriangleJaw is the widest part, narrowing toward a smaller forehead (also called pear-shaped).

Why different methods can disagree

If the mirror says oval and the tape says round, neither is necessarily wrong. A few things cause most disagreements:

That is why the face shape detector gives a percentage for every shape. When two shapes are close, use the advice they share.

What to do with your face shape

Once you know your shape, each shape guide lists the haircuts, glasses, beard styles and makeup techniques that balance it. The general idea is simple: add length where the face is short, add width where it is narrow, and soften strong angles or define soft curves. Treat these as suggestions, not rules.

How to determine face shape: FAQ

What is the easiest way to determine my face shape?

Upload a front-facing photo to the free face shape detector. It measures your forehead, cheekbones, jaw and face length automatically and shows the closest shape with a confidence score. The mirror trace method is the easiest option without a phone.

Which measurement matters most?

Face length divided by cheekbone width. It separates short faces (round, square) from long ones (oblong) before anything else. The jaw corner then separates square from round.

Do I measure face length from the hairline or the eyebrows?

From the hairline. Style guides and this site measure face length from the center of the hairline to the bottom of the chin. Starting at the eyebrows or nose bridge makes every face look shorter and rounder.

What if I am between two face shapes?

That is normal. Faces are continuous and the seven names are categories. Read the guides for both shapes and use the advice they have in common.

Can I determine my face shape from a selfie?

Yes, if the selfie is straight-on, at eye level and at arm’s length or more. Close, low-angle phone selfies make the chin and jaw look larger. Pull your hair back and keep a neutral expression.
