Which haircut suits a man's face shape? Two measurements decide it, and a barber can work from the numbers

Most guides for men describe a face as strong or soft and leave it there. Two numbers separate the seven shapes, both can be taken with a tape measure in about a minute, and the thresholds are published on this page so the working can be checked.

7 of 10
Cuts that suit an oval face

The most accommodating shape, which is why it gets used as the reference.

3 of 10
Cuts that suit a round face

The narrowest field of the seven, and the reason a round face gets bad advice.

Measurements that settle it

Face length over cheekbone width, and jaw width over cheekbone width.

The short version

Two divisions do the work. Measure your face from hairline to chin and divide by the width across your cheekbones: under about 1.10 the face is as wide as it is long and reads round or square, over about 1.58 it reads oblong. Then measure across your jaw, below the ears, and divide by the same cheekbone width: under about 0.72 the jaw is clearly tapered, over about 1.02 it is the widest part of your face. Everything else is a combination of those two calls. A cut then either repeats what those numbers already say, or offsets it, and repeating is what makes a haircut look wrong on a man who suits it in the photograph.

01Take the two measurements

A soft tape measure and a mirror. Hair back off the forehead and off the ears, because hair covering either one is the single most common reason a home measurement comes out wrong.

  1. 1Face length: from your hairline down to the bottom of your chin, straight down the middle.
  2. 2Cheekbone width: across the widest point of your face, which is usually level with the outer corner of each eye.
  3. 3Jaw width: from one jaw corner to the other, below the ears, following the bone rather than the neck.
  4. 4Divide face length by cheekbone width. Divide jaw width by cheekbone width. Those two figures are the whole answer.

02Read the two numbers against the thresholds

These are the centres the tool on this site scores against. They are editorial thresholds rather than anthropometric norms, which is exactly why they are printed rather than hidden: a reader can disagree with a number they can see.

The seven shapes, as two divisions
ShapeLength over cheekJaw over cheekWhat it means in a mirror
Round1.060.88As wide as it is long, with a soft jaw
Square1.100.97As wide as it is long, jaw as wide as the cheekbones
Triangle1.161.02Jaw the widest part of the face
Heart1.220.72Broad brow tapering to a narrow chin
Diamond1.270.74Cheekbones widest, brow and jaw both narrower
Oval1.380.82Longer than wide, jaw gently tapered
Oblong1.580.84Distinctly longer than wide

Round and square differ only in the jaw. Their length figures sit within four hundredths of each other, which is inside anyone's measuring error, so the jaw division is the one that decides.

03What a cut does to each number

A haircut cannot change a face. It changes the outline around it, and only in two directions worth naming.

  • Height at the crown adds to apparent face length. It helps a round or square face and works against an oblong one.
  • Width at the sides adds to apparent width. It helps an oblong face and works against a round one.
  • Length past the jaw draws attention to the jaw. That suits a face with a tapered jaw and fights one that is already widest there.
  • Exposing the jaw completely, with very short sides, states whatever the jaw measurement already says. On a wide jaw it emphasises width rather than hiding it.

04How many cuts actually suit each shape

Counted from the ten masculine cuts in the gallery on this site. The spread is the point: an oval face suits 7 of them and a round face suits 3, which is why generic advice reads as useful to some men and useless to others.

Cuts that suit each shape, out of 10
ShapeCuts that suit itWhat the shortlist has in common
Oval7Almost anything, which is why it is the reference rather than a goal
Square5Texture on top, nothing that squares off the outline further
Heart4Weight kept low, near the jaw, rather than piled at the crown
Diamond4Width at the brow and the jaw, not at the cheekbones
Triangle4Volume high, sides kept off the jaw
Oblong3Width at the sides, height kept down
Round3Height at the crown, sides tight, nothing rounded

A low count is not a verdict on the face. It means the popular cuts of the moment happen to sit against those proportions, which is worth knowing before sitting in the chair rather than afterwards.

05What to say to a barber

A barber works in lengths and guards, not in shape names. Naming the shape is less useful than naming the effect, and the two numbers give the effect directly.

  • If the length figure is low, ask for height at the crown and the sides kept tight.
  • If the length figure is high, ask for the sides left with some weight and the top kept down.
  • If the jaw figure is high, ask for the volume above the ear rather than below it.
  • If the jaw figure is low, weight near the jaw is available and usually flattering.
  • Say the numbers out loud. A barber who is told the jaw measures the same as the cheekbones understands the face faster than one told it is a square.

Sources

Every figure quoted above is listed here with what it was used for and when the source was last checked. Anything not attributed to a source is this site’s own reading and is labelled as such where it appears.

Check it against your own measurements

The gallery filters to masculine cuts and to a length, and every entry names the shapes it suits and the one it fights. It uses the same thresholds this page prints, so the shortlist and the reasoning are the same thing.
