Best Hairstyles for Oval, Round, Square, Heart, Diamond and Oblong Faces

The right haircut balances your proportions: it adds what your face shape lacks and softens what dominates. This guide covers all six face shapes with cuts for women and men, the cuts to avoid, and the measurements that define each shape so you can check yours rather than guess.

First, find your face shape

Face shape comes down to three ratios, all measured relative to cheekbone width:

1. Length ÷ width: upper forehead to chin, divided by cheekbone width. Around 1.45 is balanced; 1.30 or less reads round; 1.55 or more reads long.
2. Forehead ÷ cheekbones: a wider forehead points toward heart; a narrower one toward diamond.
3. Jaw ÷ cheekbones: 0.87 or more is the signature of a square face; 0.72 or less of a heart.

The face shape detector measures all three from a selfie in your browser and shows a probability for each shape. Most people are a blend of two shapes, so read both sections.

Oval

Oval faces are balanced in length and width with a jaw slightly narrower than the forehead, so almost every cut works.

• Women: long sleek middle part, textured pixie shag, chin-length French bob, long face-framing layers.
• Men: buzz cut, slicked-back undercut, classic side part, textured crop.
• Avoid: heavy fringes that hide your proportions.

Round

Round faces have a length close to their width and a soft jaw. Add vertical lines and a few angles.

• Women: long face-framing layers starting below the chin, deep side part with waves, sleek high ponytail, long middle part kept smooth at the sides.
• Men: modern quiff, textured crop with a low fade, slicked-back undercut, wavy pompadour.
• Avoid: chin-length blunt bobs, heavy straight-across bangs, volume at the sides.

Square

Square faces have a strong, wide jaw with a sharper angle. You can show it off or soften it.

• Women: shoulder-length wavy shag, side-part Hollywood waves, long layers that fall past the jaw, curtain bangs lob.
• Men: textured crop with a fade to show the jaw; medium flow or classic side part to soften it.
• Avoid: blunt cuts that end exactly at the jaw.

Heart

Heart faces have a wider forehead and a narrower chin. Add width at chin level.

• Women: chin-length French bob, curtain bangs, side-swept fringe, voluminous curly lob.
• Men: curtain fringe with a middle part, messy fringe, textured French crop.
• Avoid: height and volume at the crown; slicked-back styles that expose the full forehead.

Diamond

Diamond faces are widest at the cheekbones with a narrower forehead and chin.

• Women: side-swept fringe, curly lob, textured pixie with volume at the crown sides, face-framing layers.
• Men: messy fringe, textured French crop, buzz cut to show structure.
• Avoid: center-parted, sleek styles that emphasize cheekbone width.

Oblong

Oblong faces are noticeably long with straight sides. Add width and shorten the length.

• Women: soft blunt bangs with long layers, voluminous curly lob, curtain bangs lob, shoulder-length wavy shag.
• Men: curtain fringe, messy fringe, medium flow, classic side part.
• Avoid: tall quiffs and pompadours, very long sleek hair with a center part.

Beyond face shape

Three more measurements refine the choice:

• Facial thirds: a long upper third calls for a fringe; a long lower third for volume at jaw level. Measure them with the golden ratio calculator.
• Jawline: a strong jaw can carry short sides; a soft jaw benefits from tapered sides that add contrast. See the jawline rating test.
• Symmetry: side parts hide small asymmetries better than strict center parts. Check with the face symmetry test.

Hair texture changes the rules

• Fine, straight hair collapses at the sides, which naturally lengthens the face. Great for round faces; oblong faces need layers and blow-dried volume to compensate.
• Thick or coarse hair adds width. Square and round faces benefit from thinning and longer layers; oblong and heart faces can lean into it.
• Curly and coily hair adds the most width and changes shape with humidity. Shape the silhouette around your face: rounder for long faces, longer and more elongated for round faces.

How to brief your stylist

Bring your measurements, not just a photo of someone else. Tell your stylist your face shape and the one proportion you want to balance ("my lower third is long, I want width at the jaw"). Show the try-on render of the cut on your own face, and ask where the weight line will fall relative to your cheekbones and jaw, since that line is what changes your proportions.

See it before you cut

Face-shape charts are a starting point; seeing the cut on your face is what convinces you. The AI hairstyle try-on matches cuts to your measured shape, and the full report renders six of them on your own photo with your features unchanged. In the Try-On Studio you can upload any haircut photo and get a compatibility score first.
