What do I need to measure my face?

A soft sewing tape measure, or a piece of string plus a ruler, and a mirror. Four measurements: face length, forehead width, cheekbone width and jaw width. About three minutes.

Why is there no chin-width field?

Because chin taper cannot be measured reliably with a tape measure, and we would rather leave a feature out of the calculation than guess at it. The classifier sets that feature's weight to zero for calculator input and says so on the page.

Why is my confidence capped at 70% here?

The calculator works out your jaw angle from the four widths you entered instead of measuring it on a photo. An estimated input deserves a lower confidence ceiling than a measured one, so the result page caps it and tells you that the cap was applied.

Can I enter measurements in inches?

Yes. Centimetres and inches are both accepted; inches are converted at exactly 2.54 cm. Only the ratios between your measurements matter, so the unit does not change your result.

How to measure

Face length
From the centre of your hairline straight down the middle of your face to the tip of your chin. Keep the tape flat against the skin, not floating over the nose.
Forehead width
Across the widest part of your forehead, usually halfway between your eyebrows and your hairline, edge to edge.
Cheekbone width
Across the tops of your cheekbones, starting just outside the corner of one eye and ending at the same point on the other side.
Jaw width
From the widest point of one jaw corner — about an inch below the ear — across to the same point on the other side. Not around the chin: straight across.

Common mistakes

Measuring the jaw around the chin — The jaw measurement is a straight line between the two corners under your ears. Following the chin line instead makes every face read wider-jawed than it is.
Pulling the tape tight — Skin compresses. Rest the tape against the face without tension, or every width shrinks by a few millimetres and the ratios drift.
Tilting the head — Looking down shortens the face length and widens the jaw in one move. Measure facing a mirror with your head level.
Measuring over a fringe — Hair adds width to the forehead and hides the hairline, which is where face length starts. Push hair back for the measurement.

Pull the tape straight across, not following the curve of your face.
