Face shape, and the one honest thing it tells you
15 August 2026 — 5 min read
Face shape is one of the few things about a face that can be measured rather than judged. It is also the thing most heavily loaded with advice that does not survive contact with a real person.
Working out yours
Tie your hair back, face a mirror straight on, and compare four measurements: forehead, cheekbones, jaw, and the length from hairline to chin.
- Oval — length greater than width, forehead slightly wider than jaw, no hard angles
- Round — length and width close, soft jaw, widest at the cheeks
- Square — length and width close, jaw as wide as the forehead, with a defined corner
- Heart — forehead wider than jaw, narrowing to a pointed chin
- Long — noticeably longer than it is wide, widths fairly even
- Diamond — narrow forehead and jaw, cheekbones clearly the widest point
Most people are between two of these. That is normal and not a failure of the categories.
What it usefully tells you
Where the width already is, and where it is not. That is genuinely useful for two decisions: where to place blush, and how much definition the jaw needs. Blush on the apples pushes width forward; blush swept up towards the temple pulls it up. Neither is right or wrong until you know which direction you want to go.
What to ignore
The long lists of what each shape must never wear. Almost all of it comes from the same 1970s magazine template and treats a face as a geometry problem to be corrected towards oval. There is no reason a round face should be sculpted into an oval one, and the makeup that tries usually looks like makeup that is trying.
Boirelle reads face shape as one of seven values, prints it plainly, and uses it to place cheek colour. It does not tell you your face is the wrong shape, because it is not.
