How to Measure Your Face Shape at Home

No photo needed. With a soft measuring tape, a mirror and two minutes, you can find your face shape from four simple measurements — the same proportions stylists use.

What is face shape measurement? Face shape measurement is sizing up your face by hand: measure forehead, cheekbone and jawline widths plus face length with a soft tape, then compare the numbers. The ratios reveal your shape — for example, an oval face is about one-and-a-half times longer than wide, with the forehead slightly wider than the jaw.

The Four Measurements

Pull your hair back, relax your face, and write each number down in inches or centimeters.

  1. Forehead width

    Measure across the widest point of your forehead, from temple to temple. Keep the tape flat and level.

  2. Cheekbone width

    Measure across your face just below the outer corners of your eyes — this is usually the widest part of the cheeks.

  3. Jawline width

    Measure from the tip of your chin up to just below your ear, where the jawbone ends. Double that number for the full jawline width.

  4. Face length

    Measure from the center of your hairline straight down to the tip of your chin.

Reading Your Numbers

Compare the four numbers. These are the same ratio rules our classifier uses:

  • Oblong — face length is clearly more than 1.5× your width.
  • Round — face length is about the same as your width.
  • Square — forehead, cheekbone and jaw widths are all about equal, with an angular jaw.
  • Heart — your forehead is the widest measurement and your chin is narrow.
  • Diamond — your cheekbones are the widest measurement.
  • Oval — face length is about 1.5× your width, with the forehead slightly wider than the jaw.

Measuring FAQs

Fiddly bits, answered.

How accurate is a tape measure compared to the AI scan?

The AI scan maps 68 facial landmarks and applies the same proportions automatically. A tape measure gives you the same core ratios by hand — forehead, cheekbone, jaw and face length. Both are estimates for style guidance, not medical measurements.

Where exactly is my hairline for the face-length measurement?

Measure from the center of your hairline — the middle point where your hair starts growing on your forehead — down to the tip of your chin. If your hairline is uneven or rounded, use the midpoint.

Where does the jaw measurement end?

Measure from the tip of your chin up to just below your ear, where the jawbone ends at the angle of the jaw. Double that number for your full jawline width.

What if my face is asymmetrical?

Everyone is slightly asymmetrical — that's completely normal. Measure both sides and use the average, or simply use the side that gives the cleaner reading. Small differences won't change your overall shape.

How often should I remeasure my face shape?

Rarely. Your bone structure doesn't change, so one careful measurement is enough. You might remeasure after significant weight change, but for everyday style guidance your original numbers still apply.
