Heart vs Square Face Shape
Heart and square faces differ at the forehead and jaw: heart faces widen through the brow and taper to the chin, while square faces keep forehead, cheek, and jaw widths closer together.
Quick answer
Same wide forehead. The jaw decides.
Square keeps a broad jaw; heart tapers to a point. A wide forehead fits both, so look at how your face ends. The detector's strongest heart condition is a chin of 100° or tighter; square adds points for 113° or wider.

Your chin and jaw separate this pair, not your forehead. Heart scores most strongly with a chin angle of 100° or tighter. Square scores with a jaw angle of 136.5° or tighter, and a jaw at least 0.885 of cheekbone width and a chin of 113° or wider add points.
Heart's second route is why the two get confused: temples at least 1.15 times jaw width, a forehead at least 0.70 of cheekbone width and a broad chin, 115° or wider, so a wide-topped square face can collect heart points, though a broad jaw works against it. The main chin conditions sit 13° apart.
These are photo-landmark ratios; for tape measurements, use the face shape calculator.
Which one are you? The mirror check
Face a mirror, hair off your forehead and jaw.
- Does your face narrow to a pointed chin? Yes points to heart.
- Is your jaw nearly as wide as your forehead? Yes points to square.
- Are there sharp corners at your jaw? Yes points to square.
- Is your forehead clearly the widest part of your face? Yes points to heart.
Heart and square side by side
The detector row adds points; it is not a gate.
| Aspect | Heart | Square |
|---|---|---|
| Forehead | Widest third | Similar to jaw width |
| Jaw | Narrower chin | Angular jaw, nearly as wide as the cheekbones |
| Overall outline | Wide at the top, tapering to the chin | Box-like balance |
| How the detector scores it | ∠chin ≤ 100° (strongest); + W_temple / W_jaw ≥ 1.14; + W_temple / W_jaw ≥ 1.15 with ∠chin ≥ 115° and W_forehead / W_cheek ≥ 0.70 | ∠jaw ≤ 136.5°; + W_jaw / W_cheek ≥ 0.885; + ∠chin ≥ 113° |
| Styling aim | Balance a wider top with a narrower chin: fullness at the jaw, and frames wider at the bottom. | Soften the angles: layers and movement around the jaw, and rounded or oval frames. |
When photos sit between both
A broad forehead can earn heart points on a square face, so results often name both.
Anything over your lower face moves it: a beard reshapes the jaw and chin, hair hides the jaw corners, and a dipped chin reads narrower. Keep your chin level, jaw clear and light even.
A "mostly square, some heart" result means the shared frames are a safe start.
Styling implications
Frame advice converges for this pair; hair and beard advice pull in opposite directions at the jaw.
Hair
Heart adds weight at the jaw: a Chin-length bob balances a wider forehead and Side-swept bangs reduce its width (men's: Tapered sides, fuller front). Square softens what is there: Soft waves past the jaw ease the jawline and a Side-parted medium cut breaks the outline (men's: Textured crop with a side part). Square avoids razor-sharp bobs and severe centre parts that underline the jaw; heart avoids crown volume over a tight chin, which widens the forehead. Rank cuts with the hairstyle recommender.
Frames
Oval, Aviator and Round are on both lists: for heart they balance a narrower chin; for square, their curves soften the corners. Heart adds Rimless, square Cat-eye (women's). Heart skips heavy top bars; square, boxy rectangles. See the glasses finder, glasses for a heart-shaped face and best glasses for a square face.
Beard (if you grow one)
Heart adds chin weight: Fuller chin, lighter cheeks or a Circle beard. Square eases the corners: a Rounded full beard or Even light stubble. Heart avoids heavy cheeks over a sparse chin; square, sharp boxed corners. More in the men's face shape guide.
Not sure if you're heart or square?
Upload a front-facing photo with your jaw clear. The detector measures your face widths and jaw and chin angles, then names your likely shape, or both, with a confidence label. Landmarks are found in your browser first; the photo is sent once, encrypted, for quality checks and isn't stored.

Frequently asked questions
Can a square jaw look heart-shaped with a wide forehead?
Yes at a glance; measure cheek and jaw widths to see which third dominates. Then check the chin: pointed suggests heart, broad suggests square.
Which shape suits side parts?
Both do. On a heart face, Side-swept bangs reduce forehead width; on a square face, an off-centre part breaks the outline, as in a Side-parted medium cut. Heart faces also balance with volume at the jaw.
What if I'm somewhere between the two?
That is common. When your measurements sit near the line between two shapes, the face shape detector names both and shows how close you are to each, and styling ideas from either will work.
Why can a square face score points for heart?
Heart's second route rewards a wide forehead and temples over a broad chin, so a wide-topped square face can meet it; jaw angle and jaw width then decide.
Can I wear the same glasses with either shape?
Largely: Oval, Aviator and Round frames suit both. Skip heavy top bars if you read heart, boxy rectangles if square.
Why did my result say Medium or Lower confidence?
Something held the read back: a beard or hair over your jaw, a dipped chin, or heart and square scoring close. Lower confidence is an honest result, not an error. A straight-on photo in even light usually firms it up.
