Oblong and heart face shapes confuse people for one consistent reason: both can appear elongated, and both are less common than round, oval, and square. But their structures are fundamentally different — and their styling needs are often opposite.
Identifying which shape you actually have is not a matter of opinion. It’s a measurement question. And getting the answer right matters because a hairstyle that works beautifully for a heart face can actively worsen the proportions of an oblong face, and vice versa.
The Structural Difference
The defining difference between oblong and heart face shapes comes down to one measurement: the relationship between forehead width and jaw width.
In an oblong face, the forehead, cheekbones, and jaw are all roughly equal in width — within 12% of each other. The face is long, but it is consistently wide from top to bottom.
In a heart face, the forehead is significantly wider than the jaw. The forehead-to-jaw ratio is typically above 1.20 (meaning the forehead is at least 20% wider than the jaw). The face tapers from a wide top to a narrow, often pointed chin.
This single ratio separates the two shapes definitively in the measurement formula:
- Oblong: Width consistency ≥ 88% (all three widths within 12% of each other)
- Heart: Forehead ÷ Jaw > 1.20 (forehead meaningfully wider than jaw)
A face cannot be both at the same time. If your forehead is significantly wider than your jaw, you have a heart shape characteristic, regardless of how elongated the face appears.
Side-by-Side Comparison
- Face Length: Both oblong and heart shapes can appear long. Oblong typically has an L/W ratio of 1.50+. Heart shapes range more widely — 1.15 to 1.40.
- Forehead: Oblong forehead is medium to wide, similar to cheekbones. The forehead is the widest point of the face, visibly wider than both cheekbones and jaw.
- Cheekbones: Oblong cheekbones are similar in width to the forehead and jaw. Heart cheekbones are often the second-widest point, less prominent than the forehead.
- Jaw: Oblong jaw is similar in width to the forehead. Heart jaw is narrow — the face tapers to a point at the chin.
- Chin: Oblong chin is slightly rounded or mildly pointed. Heart chin is typically distinctly pointed or very narrow.
- Overall silhouette: Oblong reads as a tall rectangle with soft corners. Heart reads as an inverted triangle — wide at the top, narrow at the bottom.
Celebrity References
This is where visual confirmation is useful. Looking at confirmed examples of each shape side-by-side is one of the fastest ways to identify which category you fit.
- Oblong examples: Benedict Cumberbatch, Blake Lively, Ben Affleck. Note the consistent width from forehead to jaw — no dramatic narrowing at the chin.
- Heart examples: Reese Witherspoon, Ryan Gosling, Taylor Swift. Note the visibly wider forehead tapering to a narrow chin. The face’s widest point is clearly at the top.
If your silhouette matches the oblong examples — consistent width throughout — follow oblong guidelines. If your silhouette matches the heart examples — wide top, narrow bottom — follow heart guidelines.
Hairstyle Differences: The Practical Impact
This is where the distinction has maximum practical impact.
- Oblong face styling goal: Add horizontal width across the whole face. Curtain bangs, side volume, waves, wolf cuts. Avoid height at the crown.
- Heart face styling goal: Add width at the jaw and chin level to balance the wide forehead. Reduce width at the forehead (avoid full fringes that emphasise width at the top).
Notice the direct conflict: full bangs work beautifully for oblong faces (they shorten the forehead) but can make heart faces appear top-heavy (they emphasise the already-dominant forehead).
Side-swept bangs are the compromise option — they work reasonably well for both shapes because they add some forehead interruption without fully emphasising the width. But if you have a true heart shape and try the full-fringe approach recommended for oblong faces, you’ll likely dislike the result.
For oblong faces:
- Curtain bangs and full fringes: excellent
- Chin-length bob: excellent (adds width at jaw level)
- Wolf cut with side volume: excellent
- High updos: avoid
For heart faces:
- Chin-length bob: excellent (adds jaw-level width)
- Side-swept bangs: good (slightly reduces forehead emphasis without adding to it)
- Full fringe: avoid (emphasises already-wide forehead)
- Volume at chin level: excellent
- High, voluminous updos: avoid
The chin-length bob appears in both lists — it works for both shapes because it adds width at jaw level, which both shapes benefit from, though for slightly different reasons.
How to Measure: Oblong or Heart?
Take your four measurements (forehead, cheekbones, jaw, face length) as described above.
Calculate:
- Forehead ÷ Jaw = the heart-vs-oblong diagnostic ratio
If this number is above 1.20: significant heart shape signal. If this number is 0.95–1.12: oblong or oval signal (widths are consistent). If this number is 1.12–1.20: a blended zone — you may have elements of both.
Also, calculate your L/W ratio (face length ÷ average of three widths). A high L/W ratio (1.5+) with low forehead-jaw discrepancy: oblong. A moderate L/W ratio with high forehead-jaw discrepancy: heart. A high L/W ratio AND significant forehead-jaw discrepancy: a long heart shape or an oval-heart blend.
Glasses: Where the Two Shapes Diverge Sharply
For oblong faces: wide frames, round frames, browline frames. The goal is horizontal emphasis everywhere.
For heart faces: bottom-heavy frames that add visual weight at the jaw level. Aviators (wider at the bottom), round frames (that add width lower in the face), light frames that don’t emphasise the already-dominant forehead.
Cat-eye frames work for oval and some heart faces. For oblong faces, cat-eye frames emphasise the vertical length.
Frequently Asked Questions
What is the difference between oblong and heart face shapes?
The key difference is width consistency. Oblong faces have roughly equal widths across the forehead, cheekbones, and jaw — all within 12% of each other. Heart faces have a forehead that is at least 20% wider than the jaw, creating a visible taper from a wide top to a narrow chin. Both shapes can appear elongated, but their structures — and their styling needs — are significantly different.
How do I know if I have a heart or oblong face shape?
Measure your forehead width and your jaw width. Divide the forehead by the jaw. If the result is above 1.20 (forehead more than 20% wider than jaw), you have heart shape characteristics. If the result is below 1.12 (widths are close to equal), you have oblong or oval characteristics. Numbers between 1.12 and 1.20 suggest a blended shape with elements of both.
Can I have both heart and oblong characteristics?
Yes — blended shapes are common. A face can be elongated (L/W ratio above 1.45) and also have some forehead dominance (forehead 15% wider than jaw). This creates a “long heart” shape that benefits from a combination of oblong and heart styling principles. The most practical approach is to identify which characteristic is more pronounced — the elongation or the forehead dominance — and follow the corresponding guidelines more heavily.
What hairstyle works for both heart and oblong face shapes?
The chin-length bob is the clearest overlap: it adds width at jaw level, which benefits both heart shapes (balancing the narrow chin) and oblong shapes (adding horizontal framing at the face’s lower section). Side-swept bangs also work reasonably well for both, as they interrupt the forehead without fully emphasising it. These two styles are reliable choices when you are uncertain which shape you have.
Is heart face shape rare?
Heart face shapes account for approximately 11% of the adult population — the fifth most common shape. It is rarer than oblong (~14%) but more common than diamond (~5%). Heart shapes are significantly overrepresented in acting and modelling, similar to oblong, because the dramatic forehead-to-jaw taper photographs with strong visual interest.
