The best glasses for a round face: shapes, sizing and colors

What is the best glasses shape for a round face?

Start with frames that have straight lines and corners: square and wayfarer-style frames are the strongest matches, and browline, cat-eye and octagon (geometric) frames also work well. Their angles add structure to a soft outline. The shapes to use with care are round and oval: they repeat the curve of the face and can make it look rounder.

Shape is only one of three things that decide whether glasses suit you. The other two are size, meaning how wide the frame is compared with your face, and where the frame’s weight sits. A well-sized round frame can look better than a badly sized square one, so check the fit before you rule anything out.

None of this is a rule you have to follow. Round frames on a round face are a perfectly good look if you like the softness; you are simply choosing to repeat the curve rather than contrast it.

Do I actually have a round face?

A round face is about as long as it is wide, full at the cheeks, with a softly curved jaw and chin. That is different from having full cheeks: a long face can have soft cheeks, and a round outline can have well-defined cheekbones. The outline is what frames change, so that is what to check.

To check at home, pull your hair back and take a straight-on photo at eye level. Compare the length of your face with its width across the cheekbones. In FaceRater’s face shape detector, a face shorter than 1.19 times its cheek width reads as round, unless the lower face clearly tapers under a wider top, which reads as heart. Many faces sit close to a neighboring shape, often oval or square, so if yours is borderline, read the advice for both.

Which glasses frames suit a round face?

The idea is contrast. A round face has few straight lines, so frames that bring their own lines add definition. Square frames are the most direct: a wide rectangle with crisp corners. Wayfarer-style frames, a trapezoid that is wider at the top, add the same structure with a slightly softer, classic feel and lift the eye line.

Browline frames, heavy along the top only, draw a strong horizontal line at brow level and lift the upper face. Cat-eye frames sweep up at the outer corners, which pulls the eye upward and outward. Geometric octagon frames sit between round and angular, so they are a good choice if sharp squares feel too severe for you.

Panto, teardrop and rimless frames are neutral on a round face: they neither help nor hurt much, so choose them for style. Round and oval frames are the two to use with care. If you love them, choose a version that is a little wider than it is deep, with a thicker or darker top rim to add a line across the curve.

How wide should glasses be for a round face?

Size usually matters more than shape. A frame that is too narrow makes a round face look wider by comparison, while one that is far too wide looks like it is sliding off. Aim for a frame about as wide as the widest part of your face, at the temples or cheekbones, with your pupils at the center of each lens or slightly toward the nose.

Depth matters too. A round face is short for its width, so frames that are wider than they are deep add length; tall, deep lenses add more roundness. Then look at the top line: it should sit near your brows rather than cut across the middle of them or float far below.

The numbers printed on the inside of a temple arm, for example 52□18-145, are lens width, bridge width and temple length in millimeters. They come from the boxed measuring system used across the optical industry, so you can compare a frame you own with one you are considering. The bridge should rest on your nose without pinching or leaving a gap, and the temples should run straight back to your ears without pressing on your cheeks or the sides of your head. Your pupillary distance needs a ruler and a mirror, or an optician.

• Frame width: Choose a frame about as wide as the widest part of your face, at the temples or cheekbones.
• Where your eyes sit: Your pupils should sit at the centre of each lens or slightly toward the nose.
• Wider than deep: Your face is short for its width: frames wider than they are deep add length.
• Top line: the top of the frame follows your brow line rather than cutting through your brows.
• Bridge: it sits flat on your nose with no pinching or gap; a keyhole or adjustable nose pads help if frames slide down.
• Temples: they run straight back to your ears and do not dig into your cheeks or the sides of your head.

Where should the frame’s weight sit?

Put the frame’s visual weight where your face is narrower. If your round face is a little wider at the top, thinner tops or rimless styles with some weight lower down keep it balanced. If it is wider at the bottom, frames heavier along the top, such as browline or wayfarer-style frames, help. If your eyes sit close together, a thin or clear bridge opens up the space between them; if they sit further apart, a thicker or darker bridge draws them together.

Thickness is part of weight. A medium or thick rim adds more definition than a thin wire, which makes it a quick way to add structure to a round outline. Thin metal or rimless frames are lighter and change the outline less, which suits people who want their glasses to recede.

What frame colors suit a round face?

Darker and more saturated colors read as stronger lines, so they add more structure: black, dark tortoiseshell, navy or deep green. Clear, pale or very light frames soften the line and make it more forgiving if you pick a rounder shape.

Beyond that, choose color by your coloring rather than your face shape. Warm undertones tend to look good in tortoiseshell, honey, olive and gold metal; cool undertones in black, gray, navy, burgundy and silver. A two-tone frame with a darker top and a lighter bottom gives you both: a strong brow line and a light lower edge.

Hold a frame up to your face in daylight. If the color makes your skin look clear and even, it is working; if it makes shadows under your eyes look stronger, try a softer shade.

Check the frames on your own measurements

FaceRater’s free glasses finder measures your outline from one front-facing photo: your face shape, how long your face is for its width, whether it is wider at the top or the bottom, and how far apart your eyes sit. It then ranks ten frame shapes for your outline and adds fit tips, such as wider-than-deep lenses or a lighter bridge. It gives proportions to look for rather than millimeter sizes, and the scan runs in your browser without uploading the photo.

Glasses sit beside your hair and brows, so it is worth checking them together. A lifted or slightly angled brow and a haircut with height at the crown follow the same idea as an angular frame: they add vertical lines to a round face.
