Hairstyles
- •Soft fringe or temple volume can balance a wider cheek contour.
- •Chin-length layers can add width around the lower face.
- •Tuck one side to reveal the natural cheekbone line.
Diamond Face Shape
A diamond contour is narrow at the forehead, widest across the cheekbones, and narrow again at a pointed chin. It is the least common of the seven and the most distinctive, because the widest point sits in the middle of the face rather than at the top or bottom.

These visual cues can be checked in a mirror. If several do not fit, compare the neighbouring profiles below.
- 01
The cheekbones are clearly the widest part of the face.
- 02
The forehead is narrower than the cheekbones — often noticeably so at the temples.
- 03
The jaw is narrow and the chin comes to a point.
- 04
Face length is moderate to long relative to width.
What the detector matches you against
These are the exact reference values the diamond profile uses. Your photo is scored against all seven profiles on these five measurements, and the closest ones are returned as percentages rather than a single label.
| Measurement | Diamond reference | What it means |
|---|---|---|
| Face length / cheek width | 1.49 | Visible upper-face landmark to chin, divided by cheek-level landmark width; the model does not detect the exact hairline. |
| Forehead / cheek width | 0.76 | Temple-level width as a share of cheek width. |
| Jaw / cheek width | 0.72 | Jaw-corner width as a share of cheek width. |
| Jaw corner angle | 150° | Higher is a softer, more curved corner; lower is a squarer one. |
| Chin taper angle | 96° | Higher is a broader chin; lower is a more pointed one. |
These reference values are hand-set design choices, not population averages fitted to a labelled dataset. They define what this tool means by diamond; another calculator using different landmarks will place the boundaries elsewhere.
If diamond does not feel right
Heart
Both have a pointed chin. A heart is widest at the forehead; a diamond's forehead is its narrow point.
Read the heart guide →Oval
Very close in length and jaw, and the two most frequently tied in this detector's ranking. The forehead measurement is the separator — an oval's is proportionally wider.

These are visual-balance conventions, not rules. They describe where volume, width or a line is usually placed to work with or against the natural contour — and either direction is a valid choice.
Glasses
- •Oval or brow-accented frames can balance the cheek contour.
- •Slightly upswept corners can follow the natural diagonal line.
- •Check that the frame does not press on prominent cheek areas.
Beard shapes
- •Fuller growth along the jaw adds width to the narrowest part of the lower face.
- •A squared beard gives the pointed chin a broader edge.
- •Keeping the cheek line low avoids adding width at the already-widest point.
Contour and makeup
- •Light contour directly on the cheekbone reduces the mid-face emphasis if that is the goal.
- •Highlighting the forehead and chin evens out the three widths.
- •A fuller brow adds visual width to the narrow upper face.
Earrings, necklines and hats
- •Earrings wider at the top or bottom rather than the middle avoid repeating the cheekbone width.
- •Wide and boat necklines broaden the lower frame.
- •Frames with a strong upper line or detailed brow area add width where the face is narrowest.
About the diamond shape
Measure your own face free →Is a diamond face shape rare?+
It is the least commonly assigned of the seven in most styling guides, because it requires the forehead and jaw to both be narrower than the cheekbones. In this detector it frequently appears as a close runner-up to oval rather than a clear winner.
Why did the detector rank oval and diamond almost equally?+
Because they differ mainly in forehead width, and the forehead is the measurement most affected by hair, a fringe or a receding hairline. When the two are within a few points, pulling your hair back and re-running the photo usually separates them.
All face shapes
Oval
Moderately long, with the forehead a little wider than the jaw and a softly rounded chin.

Round
Similar in length and width, with a soft jaw that curves instead of turning a corner.
Read guide →
Square
Short and wide like a round face, but with a jaw that turns a clear corner below the ear.
Read guide →
Oblong
The longest of the seven profiles, with widths that stay fairly even from forehead to jaw.

Heart
A wide forehead narrowing to a pointed chin, often with a widow's peak.

Triangle
A jaw wider than the forehead — the inverse of the heart profile.
