A heart-shaped face is wide at the forehead and narrow at the jaw, and glasses sit right at the border between the two. The frame's job is to keep its weight low: light at the brow, fuller below, so the eye reads the lower half of the face as having more to it. Here is what that means in frames, for women and for men.
What makes a face heart-shaped, and why it matters for glasses
Face length divided by cheekbone width sits around 1.50. Forehead width over cheekbone width is about 0.96: the forehead is nearly as wide as the cheekbones, against 0.88 for oval. Jaw width over cheekbone width is about 0.76, narrower than oval's 0.80, and the chin often comes to a point. The outline is widest at the top and narrows steadily to the chin.
Glasses sit just below the widest part of this face. A frame that is heavy or wide at the top stacks weight on top of weight, and the face reads as an inverted triangle with a bar across it. A frame that is light at the top and fuller at the bottom does the opposite: the eye is pulled down toward the jaw, and the narrow lower face looks as though it has more to it. The bottom edge of the frame is doing most of the work, so it should be the part with presence.
Heart is confused with diamond (narrow jaw, but a narrow forehead) and with round (a soft chin). The face shape tool measures the forehead ratio and the mid-jaw width that separate the three.
The one principle
Weight low, light on top. Frames that are wider or heavier at the bottom, rimless and semi-rimless frames that have no top bar to speak of, and rounded shapes that spread their weight evenly all move the emphasis downward. Thick top bars, dark oversized frames and sharp upsweeps move it up. Width should stay at or a little inside the cheekbones so the frame's widest point does not line up with the face's.
Frame shapes at a glance
Frame
What it is
What it fixes
Bottom-heavy frames
Lower rim thicker or wider than the upper
The single most direct fix for a face that carries its weight up top
Rimless
No frame line at all
Adds nothing at the brow and leaves the face's own proportions alone. Especially good on men
Semi-rimless, rim below
Framed at the bottom only
Puts the only visible line under the eyes — the reverse of a browline
Round
Thin, moderate size
Even weight and no top bar; the curve above a pointed chin softens it
Oval
Even, a little wider across the eyes
Same evenness as round with more width — keep it light and inside the cheekbones
Teardrop aviator
Lens widens downward, narrows on top
Naturally bottom-heavy. Choose thin metal, not thick acetate
Soft cat-eye, pale
Gentle upsweep, thin or light colour
Draws the eye outward to balance a narrow lower face — skip sharp dark versions
Light, thin frames
Any shape, pale or clear
Whatever the shape, less weight at the brow. On this face, lighter is safer
Frame shapes that work
Bottom-heavy frames
Any frame where the lower rim is thicker or wider than the upper: inverted browlines, frames with a coloured or thicker bottom edge, and lens shapes that are wider at the bottom than the top. The single most direct fix for a top-heavy face.
Rimless
No frame line at all, so nothing is added at the brow. The lenses float and the face's own proportions are left alone, with no extra weight at the top. A classic choice for this shape, and one that works especially well on men.
Semi-rimless with the rim at the bottom
Rimless at the top, framed at the bottom. Puts the only visible line below the eyes, which is exactly where this face wants it. The reverse of the browline.
Round
Round frames spread their weight evenly and have no top bar. In a thin frame and a moderate size they soften a pointed chin by adding a curve above it. Avoid very large or very dark rounds, which become a heavy block at the top.
Oval
The same evenness as round, with a little more width across the eyes. Keep the frame light in weight and the width inside the cheekbones.
Teardrop aviator
The aviator is naturally bottom-heavy: the lens widens toward the bottom and narrows at the top. One of the best shapes for a heart face, in eyeglasses and sunglasses alike. Choose a thin metal frame rather than a thick acetate one.
Soft cat-eye, light colour
For women, a gentle upsweep draws the eye outward, which balances a narrow lower face, as long as the frame is thin or light in colour. Skip the sharp, dark, heavy versions.
Light, thin frames generally
Whatever the shape, a thin frame in a light or clear colour adds less at the brow than a thick dark one. On this face, lighter is safer.

Size, bridge and fit
Width: at or slightly inside the cheekbones. A frame wider than the face lines up with the widest part of the head and emphasises it.
Top bar: as thin as possible, or absent. This is the part of the frame to keep quiet.
Lower rim: the part to give presence: thicker, coloured, or wider than the top.
Colour: lighter, clearer and warmer colours add less weight than black or dark tortoise. If you want a dark frame, keep it thin.
Bridge: a low bridge sits the frame lower on the face, which moves its weight down. Avoid high, prominent bridges.
Temples: thin temples attached at the middle or bottom of the frame keep the top light.
Sunglasses for a heart shaped face
Sunglasses are harder for this shape than eyeglasses, because they are larger and darker by default and most of the popular styles are top-heavy. Choose carefully.
Teardrop aviator
The best sunglass shape for a heart face. Bottom-heavy by design.
Round, thin frame
Moderate size, thin rim. Large thick rounds add a block at the top.
Rimless or semi-rimless
Sport and fashion rimless styles work; they add nothing at the brow.
Bottom-heavy shapes
Frames described as inverted, butterfly (the wider-at-the-bottom kind), or with a coloured lower rim.
Lighter lens and frame colours
Gradient lenses that are lighter at the bottom, and frames in clear, light or tortoise rather than black.
What to skip
Browline and clubmaster sunglasses, flat-top and shield styles, oversized dark squares, and sharp cat-eyes. All are heaviest at the top.
What to avoid, and why
Browline and clubmaster frames. All their weight is in a bar at the brow, the widest part of the face. This is the heart-face mistake in glasses.
Thick, dark top bars of any kind. Same reason: weight where there is already too much.
Oversized dark frames. A heavy block at the top of a top-heavy face.
Sharp, heavy cat-eyes. The upsweep and the dark corner both add at the brow. Keep cat-eyes soft and light.
Frames wider than the face. Line up with, and emphasise, the widest point.
Flat-top and shield sunglasses. A straight heavy line across the top. The opposite of what this face needs.
If you are leaning toward another shape
Heart leaning diamond (forehead ratio nearer 0.85): the top needs less protecting and a light browline becomes possible. See the diamond guide.
Heart leaning round (soft chin, jaw ratio nearer 0.82): keep the frames light on top and add a little angle; a thin rounded-rectangle works. See the round face guide.
Heart leaning oval (ratios nearer 0.88 and 0.80): most restrictions relax. See the oval guide, keeping a light preference for thinner top bars.
Frames that carry their weight low: styles wider or heavier at the bottom than the top, rimless and semi-rimless frames, round and oval shapes, and aviators. A heart-shaped face has a forehead nearly as wide as the cheekbones (about 0.96) and a narrow jaw (about 0.76), so it is top-heavy; a frame that is light at the brow and fuller below moves visual weight down toward the jaw. Thin, light-coloured frames also help because they do not add to the width at the top.
What glasses should a heart shaped face avoid?
Anything heavy at the brow: browline and clubmaster styles, thick top bars, dark oversized frames that are widest at the top, and sharply upswept cat-eyes. All of them add weight and width to the part of the face that already has the most. Very wide frames are also a risk, because the widest point of the frame lines up with the widest point of the face.
Do heart shaped faces suit cat-eye glasses?
Soft ones, in a light colour or a thin frame. A gentle upsweep draws the eye outward without adding much at the brow. The sharp, heavy, dark cat-eyes that suit round and oval faces add exactly the top-heavy weight this shape does not need.
What glasses suit men with a heart shaped face?
Rimless or semi-rimless frames, thin metal rounds and ovals, and teardrop aviators. Searches for this shape on men are common, and the answer is unusually clear: keep the frame light at the top. A short, full beard along the jaw does more for the balance of this face than any frame, and pairs well with a lighter frame above it.
How do I know if my face is heart or round?
Both can have a soft chin. Heart has a forehead that is clearly wider than the jaw; round has forehead and jaw at similar widths. Measure forehead width divided by cheekbone width (heart sits near 0.96) and jaw over cheekbone (near 0.76). The tool also reads the mid-jaw width, which is the measurement that separates the two most reliably.

Heart, or round with a narrow chin?
Heart is separated from round by the mid-jaw width and from diamond by the forehead. The scanner measures all three from a photo and tells you which shape you are closest to.
