- Three slices, top to bottomHairline to brows, brows to nose, nose to chin, each as a share of the face.
- Even thirds are a rule of thumbReal faces rarely split exactly evenly. The page shows how far each third is from even.
- Photo and hairline matterProp the phone at eye level, about 1.5 m (5 ft) away. Your hairline is where forehead skin meets hair in the middle; push a fringe back first.
What you can change
Hair can make one part of your face look longer or shorter.

Questions
What is a facial harmony test?
A facial harmony test checks how the parts of your face compare in size. This one is the facial thirds calculator: it compares your hairline-to-brows, brows-to-nose and nose-to-chin lengths. There is no score or rating, and uneven thirds are normal.
How do I measure my facial thirds?
Mark your hairline, the point between your brows, the base of your nose and the bottom of your chin. Measure the three gaps and divide each by the total. Even thirds come out at 33.3% each.
Are equal thirds normal?
They're rare. Equal thirds are an artists' rule; real faces seldom split exactly evenly. The page compares each third with an even third (33%).
Why do selfies throw off my thirds?
Camera tilt. A phone held high makes the forehead look bigger, held low the chin. Prop your phone at eye level, about 1.5 m (5 ft) away, or ask someone to take it.
How do I balance a short lower third?
Men: a short beard, a little fuller on the chin. Women: keep hair above the chin or swept back, off the jaw.
How the facial thirds calculator measures your face
How the facial thirds calculator measures your face The four points behind your split, how each third is read, and the studies behind them.
We measure three lengths down the middle of your face: hairline to brows, brows to the base of the nose, and nose to chin, each as a share of the whole. Below: where each point goes, how each third is read with the four example faces measured, why camera tilt shifts the split, and our sources.
How to find your three facial thirds
You only need four points down the centre line of your face: the hairline, the point between the brows, the base of the nose and the bottom of the chin. Clinical guides (Powell & Humphreys 1984; Arnett & Bergman 1993) also split the lower third in two: the upper lip takes about one third of it, and the lower lip and chin about two thirds. This calculator reads the three main thirds only.
- Upper forehead third (hairline to brow centre)Starts at the center of your natural hairline (trichion) and ends at the smooth ridge right between your eyebrows (glabella). Because hair can cover the hairline, this is the easiest third to change with a haircut.
- Middle nasal third (brow centre to nose base)Runs from between your eyebrows down to the base of your nasal septum where your nose meets your upper lip (subnasale). Framed visually by your eyebrow arch height and glasses bridge placement.
- Lower jaw & chin third (nose base to chin)Measured from the base of your nose down to the lowest bony point of your chin (menton).
Neoclassical canon: 33.3% : 33.3% : 33.3%
How your split is read, with the example faces measured
The classical rule says a face splits into three equal thirds. When Farkas et al. (1985) tested these classical rules on young adults, they found that they rarely hold exactly. Milutinovic et al. (2014) later compared attractive faces with the same proportions. So this calculator doesn't rank you against other people. It compares each of your thirds with an even third (a third is 33.3%).
30% to 36% reads as about a third; 29% or less is shorter and 37% or more is longer, and the third furthest from 33% names your result. None of the seven results is better than another; they decide which haircuts and beard ideas the page suggests. If one third comes out under 15% or over 55% of the face, a dot is on the wrong point, and the tool asks you to move it instead of giving a result. Here are the four example faces, measured with the dots this page starts on:
| Face | Forehead | Middle (brows to nose) | Lower face (nose to chin) | Result |
|---|---|---|---|---|
| Even thirds (the classical rule) | 33.3% | 33.3% | 33.3% | Close to even |
| Example face 1 (woman) | 30% | 39% | 31% | Longer middle |
| Example face 2 (man) | 29% | 35% | 36% | Shorter forehead |
| Example face 3 (woman) | 31% | 35% | 34% | Close to even |
| Example face 4 (man) | 26% | 36% | 38% | Shorter forehead |
Why phone selfies make your forehead or chin look out of proportion
Facial thirds are very sensitive to up-and-down camera tilt on a close phone camera. Hold the phone above eye level and look up at the screen, and your forehead sits closest to the wide lens: it looks bigger and your lower face smaller. Hold it below chin level and the lower third grows instead.
Distance matters too: the closer the phone, the more the parts nearest the lens (forehead, nose, chin) are stretched, so a selfie from 30 cm stretches them more than a photo from 1.5 m (Ward et al. 2018; CEVO's selfie study). Before you trust any home measurement, prop the camera at eye level and at least 1.5 m (5 ft) away, or use CEVO's free scan. CEVO's scan reads your iris size (about 11.7 mm across in most adults) to tell how close the camera was, and asks for a retake if the photo was taken too close. Read more in our selfie distortion study.
| Where the camera is | What it does to your face | Good for thirds? |
|---|---|---|
| About 30 cm, a close selfie | Features nearest the lens look bigger; any tilt shifts the forehead and chin | No |
| About 50 cm to 75 cm, arm out | A little stretched | Only at eye level |
| About 1.5 m (150 cm), propped or taken by a friend | As other people see you | Yes |
| Above eye level | The forehead looks bigger, the lower face smaller | No |
| Below chin level | The lower face looks bigger | No |
