How to Find Your Face Shape: Measurements and Method

Learning how to find your face shape starts with four simple measurements, not a photograph or a guess in the mirror. Your face length, cheekbone width, forehead width and jawline width, compared in the right way, point to one of six shapes: oval, round, square, heart, diamond or oblong. Knowing your shape makes everyday choices easier, from haircuts and glasses frames to beards and eyebrow shaping, because each shape suits different lines and proportions. The comparison takes only a few minutes with a soft measuring tape, and you can check your own numbers in seconds with the free Face Shape Calculator.

Guessing from a mirror photo is unreliable, because the angle, the lighting and even a slight tilt of the head can make a face look longer or wider than it is. Measurements remove that guesswork: the same four numbers give the same result no matter who holds the tape, as long as the tape sits in the same places. This guide explains what each measurement means, how the four numbers are compared, and how to work through the method yourself, with the tool page’s own example worked out in full./

The Method / Formula

The method compares four measurements, shortened to L, C, F and J. It does not use a photograph or any single number on its own; the shape comes from how the four numbers relate to each other. The comparisons, in the order the tool applies them, are: heart, when the forehead is the widest measurement and the jawline is much narrower; diamond, when the cheekbones are widest while the forehead and jawline are narrow; oblong, when the face length is at least 1.45 times the cheekbone width; square or round, when the face length is within 1.15 times the cheekbone width; and oval, when none of those patterns fits. The tool reports the shape together with the reason, so you can see which comparison decided it.

Face length (L): the distance from the centre of the hairline to the tip of the chin, measured straight down the middle of the face. Cheekbone width (C): the distance across the face at the widest point of the cheekbones, usually just below the outer corners of the eyes. Forehead width (F): the distance across the forehead at its widest point, generally midway between the eyebrows and the hairline. Jawline width (J): the distance across the jaw at its widest point, measured between the corners of the jaw. All four are taken in centimetres, with the tape flat against the skin and the face relaxed.

How to Find Your Face Shape Step by Step

1. Stand in front of a mirror with your hair pulled back, so the hairline and jaw corners are visible.
2. Measure your face length (L) from the centre of your hairline to the tip of your chin.
3. Measure your cheekbone width (C) across the widest part of your cheekbones.
4. Measure your forehead width (F) across the widest part of your forehead.
5. Measure your jawline width (J) across the jaw at its widest point, between the jaw corners.
6. Compare the four numbers with the method above, or enter them into the calculator to get the shape and the reason.

Worked Example

Take the example from the tool page: face length 18.5 cm, cheekbones 13.8 cm, forehead 13.0 cm and jawline 12.2 cm. Working through the comparisons:

• Face length divided by cheekbone width: 18.5 ÷ 13.8 = 1.34. That is below the 1.45 oblong mark and above the 1.15 square-or-round band, so neither of those patterns fits.
• The forehead (13.0 cm) is not the widest measurement, and the jawline (12.2 cm) is only slightly narrower, so the heart pattern does not fit either.
• The cheekbones (13.8 cm) are the widest of the three widths, but the forehead and jawline are close behind, not clearly narrow, so the diamond pattern does not fit.
• Result: Oval — exactly as the tool page shows.

An oval result means the face is longer than it is wide, with gently balanced widths and no single feature dominating. It is the fallback shape in this method: when no other pattern matches, the face is classed as oval.

Common Mistakes / Good to Know

• Measuring the forehead over bangs or hair: push the hair back first, or the forehead width comes out too large and can push the result towards heart.
• Pulling the tape tight or measuring over a smile: keep the tape flat and your face relaxed, or the cheekbone and jawline widths shrink.
• Judging from a photograph: camera angle and lens distance change apparent proportions, so a photo can disagree with the tape. Trust the measurements.
• Treating the result as a strict label: the shape is a styling guide, not a rule. If your numbers sit near a boundary, either neighbouring shape’s advice will usually suit you.
