Glasses for a heart-shaped face: lighter on top, a little weight lower down

The short answer

For a heart-shaped face, choose frames that keep the top light and put a little weight lower down: bottom-heavy frames, rimless or semi-rimless styles, and light colours. Avoid heavy browline frames, which add a thick bar across the widest part of the face.

This is the optician's balancing rule applied to where the face is widest. It is a trade convention rather than a tested finding, but the logic holds: glasses sit right across the upper half of the face, and a heavy top line adds to the width already there, while a light top and a fuller lower edge pull the eye down towards the narrower chin.

How to tell if your face is heart-shaped

Use a photo from about 1.5–2 metres away, straight on, at eye level, with your hair pushed back and glasses off. A close selfie makes the middle of the face look fuller than it is — a 2018 paper in JAMA Facial Plastic Surgery modelled the effect and estimated about 30% extra apparent nose width at around 30 cm — and a camera held above you enlarges the forehead and shrinks the chin, which can make almost any face look heart-shaped.

From a level, distant photo, check three things:

1. Forehead against jaw. The forehead, measured across the temples, is clearly wider than the jaw just below the ears.
2. The chin. The face narrows to a chin that is noticeably smaller than the forehead, often coming to a soft point.
3. The hairline. Many heart-shaped faces have a hairline that dips to a point in the middle (a widow's peak) or rises at the temples. This is a common sign, not a requirement.

If the cheekbones are clearly the widest point and the forehead is narrow too, you are closer to diamond.

One naming note: some optician charts call this shape a "base-up triangle". It is the same thing — wide at the top, narrow at the bottom — and the advice is the same.

What suits a heart-shaped face, and why

Bottom-heavy frames

Frames whose visual weight sits along the lower half — lenses wider at the bottom, a thicker or darker lower rim, or a shape that flares slightly outward below the eye line. They add a little width and attention lower on the face, which balances the broader forehead.

Rimless and semi-rimless

Rimless frames add almost no line at all, so they do not add weight to the top of the face. Semi-rimless frames with the rim along the bottom (sometimes sold as "reverse half-rim") are a particularly good fit, because they are light at the top and defined at the bottom. Semi-rimless with the rim along the top is the opposite and works less well here.

Light colours

Clear, grey, pale tortoiseshell, silver and gold frames draw a softer line than black acetate. On a heart-shaped face a lighter frame keeps the upper half from looking heavier.

What to avoid, and why

Heavy browline frames. A thick, dark bar across the top of the frame draws a strong line at the brow and adds weight to the upper face, which is the part that is already widest. The result is more top-heavy, not less.

Related choices that push the same way:

• Frames wider than the forehead, which extend the top width even further.
• Thick, dark top rims of any shape, for the same reason as browlines.
• Cat-eye or upswept frames with heavy outer corners, which add width at the temples. A subtle upsweep is fine; a dramatic one adds width up top.

As ever, these are not forbidden; a thin, light browline can work. It is the weight at the top that matters.

Getting the size right

• Width. About as wide as your face at the temples and no wider. On a heart-shaped face, an overhanging frame exaggerates the width at the top.
• Depth. Medium. A frame deep enough to sit a little lower on the face helps bring attention down.
• Bridge. The frame should sit without sliding or pinching. Adjustable nose pads on metal and rimless frames make this easy.
• Height. The top rim near the eyebrow line, brows visible just above it.

Frame sizes are usually printed inside an arm, as something like 52□18 145: lens width and bridge width in millimetres (on the boxed measuring system set out in ISO 8624), then arm length. Note the numbers of a pair that fits well and use them to shortlist.

What to say to the optician

"My face is wider at the forehead and narrower at the chin, so I'd like frames that are light on top — rimless, semi-rimless with the rim at the bottom, or something a bit bottom-heavy. Nothing with a heavy brow bar, and not wider than my forehead."

Ask to compare a rimless pair and a bottom-heavy acetate pair side by side; the difference is easy to see in a photo. Rimless frames need lenses drilled into place, so if your prescription is strong, ask whether the lens material suits a rimless mount.

Colour

Light and mid-tone frames are the safer starting point here. Pick the colour family by undertone: warm skin suits honey tortoiseshell, gold and light brown; cool skin suits silver, grey and clear.

Sunglasses

Sunglasses that suit you follow the same frame shapes. Aviators are a natural fit because the lens widens towards the bottom; gradient lenses that are darker at the top are fine, since the frame shape matters more than the tint.

Trying them on properly

Photograph each pair from about a metre away, with the camera at eye level. A camera above you makes the forehead bigger and every frame look more top-heavy than it is. Compare the photos rather than the shop mirror.
