Glasses for Heart Shaped Faces: Frames That Balance the Chin
Your forehead is the widest part of your face, your chin tapers to a point, and most frames seem to make both more obvious. They do not have to.

The best glasses for heart shaped faces add visual weight at the bottom: oval, round, soft rectangular or teardrop frames with a fuller lower edge. Keep the frame no wider than your cheekbones and the top rim thin or light in colour. That balances a broad brow against a narrower chin.
How do you know if your face is heart shaped?
Your face is heart shaped when the forehead is the widest part, the cheekbones sit a little narrower, and the jaw tapers to a small or pointed chin. You can confirm it in two minutes with a ruler and a mirror. Pull your hair back and measure three widths in millimetres: across the forehead at its widest point, across the cheekbones from outer edge to outer edge, and across the jaw just below the ears. If the forehead and cheekbone figures are within a few millimetres of each other and the jaw is clearly smaller, you are in heart territory. If the cheekbones are clearly the widest, that is a diamond face, and it needs different advice. A widow's peak is common with heart shapes but not required, so do not rely on your hairline alone. Face shapes also overlap, and many people sit between two categories.
A straight-on photo, taken at arm's length with your hair tied back, is more reliable than a mirror viewed at an angle. Measure on the photo against a ruler held at cheek level if you want a second opinion. Write the three numbers down. You will use the cheekbone figure again when we get to frame size.
One more thing worth knowing: the shape matters less than the proportion. Two people with heart shaped faces can have very different forehead-to-jaw gaps, and the bigger the gap, the more a bottom-heavy frame helps.

Which frame shapes work best for heart shaped faces?
Oval, round and soft rectangular frames suit heart shaped faces best, because their curves echo the taper of your chin without adding width at the brow. Bottom-heavy shapes such as teardrop aviators come a close second: the lens grows wider as it goes down, which fills the space a narrow jaw leaves behind. The principle is counterweight. Your face is widest at the top, so the frame's widest point should sit at or below the brow line, ideally level with the cheekbones. A frame that is lighter at the top and fuller at the bottom evens out the proportions. A lens width of roughly 48-52 mm in a round or oval cut suits many adult faces, though your cheekbone width should decide the final number. Straight, hard-cornered tops are the thing to watch, since they echo the flat line of your forehead.
| Frame shape | Why it works | Watch out for |
|---|---|---|
| Oval | Soft curves follow the chin, no hard line across the brow | Very narrow ovals that sit inside your forehead width |
| Round | Fuller lower curve balances a narrow jaw | Tiny lenses under about 44 mm can look like an afterthought |
| Soft rectangle | Gentle corners add structure without a heavy top | Sharp, boxy corners and thick top rims |
| Teardrop / aviator | Lens widens toward the cheek, filling the lower face | Heavy double brow bars |
| Low-angle cat-eye | A mild lift adds interest without extra brow weight | Steeply upswept outer corners |
| Hexagonal / geometric | Angled lower edges give the jaw some definition | Wide, flat tops |
If you want our default pick, it is a soft oval or rounded rectangle in thin metal or light acetate. It is hard to get wrong. Go round when you want something more distinct, and teardrop when you want a frame that works as both everyday glasses and a sunglasses shape.
Which glasses should you avoid with a heart shaped face?
Avoid frames that are heavy across the top and light underneath. Thick, dark browlines, oversized square tops and sharply upswept cat-eyes all put the most visual weight across your forehead, which is already your widest point, and they make the chin look narrower by contrast. The test is simple: cover the lower half of the frame with one hand, then the upper half, and compare how much each reads. If the top clearly dominates, the frame is working against you. Frames that are too small are the other trap. When the frame sits inside the width of your forehead, the temples seem to flare outward, and the heart shape becomes more pronounced rather than softer. None of this is a ban. A thin metal browline in a pale colour, or a gentle cat-eye with a low angle, can look excellent. The weight distribution matters more than the style name.
A quick list of the usual offenders:
- Thick black top rims paired with a thin or invisible bottom edge
- Oversized squares with a flat, straight brow line
- Steep cat-eyes whose outer tips rise well above the brow
- Frames narrower than your forehead, which push the temples outward visually
- Very dark, heavily decorated temple arms attached high on the frame
That last one is easy to overlook. Where the temple arm joins the front changes how the frame sits against your temples. A high hinge position draws a line right across the widest part of your face.
What size should glasses for a heart shaped face be?
Pick a frame whose total width matches your cheekbones, not your forehead. Most adult frames fall between roughly 125 and 145 mm wide, and the numbers are printed inside the temple arm, for example 51-18-140: a 51 mm lens, an 18 mm bridge and 140 mm temples. Double the lens width, add the bridge, then allow for the rims and hinges, and a 51-18 frame lands around 130 mm or slightly more. Compare that with the cheekbone measurement you took earlier. A frame a few millimetres narrower than your cheekbones looks neat. One noticeably wider starts to look like a mask, and one that sits inside your forehead width makes the top of your face look broader. If you already own glasses that feel right, read the three numbers off the arm and use them as your baseline for any new order.
Lens height is the lever most people miss. A shallow lens, with a height well under 35 mm, reads as a strip across the brow and gives the lower face nothing to work with. A lens around 40 mm or taller drops the frame's lower edge toward the cheekbone and does the balancing work for you. This is why a pair that is the right width can still feel wrong: the depth is off.
Two practical checks once the glasses arrive:
- The outer edge of the frame should not stick out past your cheekbones when you look in a straight-on photo.
- Your eyebrows should sit just above the top rim, not hidden behind it and not floating far above it.
Which materials and lens options suit a heart shaped face?
Thin metal, titanium and lightweight acetate in softer, lighter tones suit heart shaped faces best, because they keep the top of the frame quiet. Titanium and fine metal rims barely register on the brow, while acetate in clear, translucent or two-tone finishes can carry a little more colour at the bottom than at the top. Rimless frames work too, as long as the lens is cut in an oval or rounded shape: the lens becomes the shape, and a rounded one echoes your chin. Flexible memory metal is a practical choice if your glasses get pushed, bent and sat on, since it tolerates a bit of abuse. Lens index changes the look as well. With a stronger prescription, a 1.61 or 1.67 index lens keeps the edges slimmer, and 1.74 is the thinnest of the four options for very strong prescriptions. Thick edges at the temples add weight exactly where a wide forehead does not need it.
A few colour rules that hold up in practice:
- Lighter or translucent colours on the top rim, deeper colours at the bottom, if the frame is two-tone
- Tortoiseshell works when the pattern is fairly even; a very dark top fading to light is the wrong way round for you
- Metal in gold, rose gold or silver tends to look lighter on the brow than black acetate of the same size
Anti-reflective coating earns its place here. Glare across the upper part of the lens pulls the eye to the brow, and in photos it turns into two bright patches right where you want less attention. If you are in and out of dim light on a grey Nottingham morning and bright sun by lunchtime, photochromic lenses save you carrying a second pair.
What about prescription sunglasses and clip-ons?
Prescription sunglasses follow the same rule: favour round, oval and teardrop shapes with the widest point at or below the brow, and treat flat-topped, heavy-browed styles with caution. Lensdy has around 18 prescription sunglasses styles, including Obsidian, AeroFold, Coastal, Eclipse and Amber, so you can run each through the shape table above and keep the ones with a fuller lower edge. Tint matters more than most people expect. A near-black lens makes any frame read heavier across the top, while a mid-tone brown, grey or green keeps the upper half lighter. Look at where the lens is widest in the product photo, not just the overall outline, because that decides whether the frame balances your chin. Keep the lens height at about 40 mm or more if you can, so the lower edge reaches your cheekbone and the sunglasses do not sit like a bar across your forehead.
Magnetic clip-ons deserve a short mention. The Magneto 3-in-1 and Polyhedron 4-in-1 (prescription frame plus sun clip plus blue light clip) add a second layer across the top of the frame when the clip is on, so choose a base frame that already suits your face. If you live somewhere with strong coastal light, a Brighton seafront in July, say, a clip-on sun layer and a clear day frame can replace two separate pairs. The base shape still needs to pass the top-versus-bottom test.
How do you test frames online before you order?
Measure your face, read the numbers off a pair you already like, and shortlist frames that match on three points: shape, total width and lens height. It takes about ten minutes and replaces the mirror you lose when you shop online. The key is to decide before you browse, so that 200 frames become six. Start with the three face widths from the first section, then add your pupillary distance (PD), since you need it for the prescription anyway. Adult PD typically falls between 54 and 74 mm. Check that your prescription is current, because frames and lenses are ordered together. Then work through the steps below and keep only frames that pass all of them. If two frames tie, choose the one with the fuller bottom edge.
- Take a straight-on photo with your hair back and measure forehead, cheekbone and jaw widths in millimetres.
- Read the lens width, bridge and temple numbers on your best-fitting current pair.
- Filter the shop for oval, round, soft rectangle or teardrop shapes.
- Reject any frame whose top rim is visibly thicker or darker than its bottom edge.
- Compare the listed frame width to your cheekbone width. Aim for equal, or a few millimetres narrower.
- Choose the lens index to suit your prescription. If you are unsure which suits a strong prescription, ask your optician.
- Add anti-reflective coating, and photochromic if you move between indoors and outdoors a lot.
One extra trick: screenshot the product photo, then hold your phone against your face in a mirror and compare where the frame's widest point falls against your cheekbone. It is crude, and it works better than most virtual try-on tools for judging proportion.
