Choosing new sunglasses for everyday wear isn’t exactly rocket science, but there are a few things to consider before investing in your next pair. First, decide on the functional elements you need — like polarized lenses, tints or coatings that combat reflections, water, oil or fog — then pick out a frame shape that complements your face shape. The goal is to accentuate your best features, and the most surefire way to do that is to wear frames that contrast your own unique structure.

Figuring Out Your Face Shape

Not sure what your face shape is? Look at yourself in the mirror and decide if your face is round, square, oblong, heart, diamond or triangular. It may also be helpful to use a picture to help you better visualize the shape.

Face Shapes

  • Round
  • Oval
  • Square
  • Oblong
  • Heart Shaped
  • Diamond
  • Triangular

    Below, we break down the more technical definition of each popular face shape (i.e. dimensions, what to look for, what one looks like), and offer recommendations that will highlight your best qualities. Still not 100 percent sure which shape your face is? There are apps — like Find Your Face Shape — that can help you, but it’s up to you whether you want a random app to own a comprehensive scan of your face made using your front-facing camera. *shrug emoji*

    How to Pick the Right Frame for Your Face Shape

    The goal is to accentuate your best features, and in general, the best way to do that is to wear frames that contrast your face’s shape slightly. If you’re rounded, go angular, with something square or oversized, and so on and so forth. See below for full details for each face shape.

    Terms to Know


    This synthetic material — also known as cellulose acetate — was first used for eyewear in the late ‘40s. It is made from a polymer derived from wood pulp or other natural fibers and is both glossy and transparent. In recent years, the material has been replaced by less-expensive nylon frames.


    This is acetate made from bio-based materials — cotton, wood pulp, cereals, beet and sugar cane, for example.


    Polarized lenses have a special film that helps them to reduce glare — that is, bright reflected light. This works by only allowing light that enters the lenses vertically — unreflected light, direct from a light source — to enter through, blocking the vast majority of light that reflects off horizontal surfaces like bodies of water, large stretches of pavement or fields of snow.

    Polarization is especially useful for people who do a lot of sunny highway driving, daytime fishing, skiing, mountaineering or hiking in snowy areas. Polarized lenses typically cost more than unpolarized ones.


    Most acetate or full-frame glasses, which are the type that require front-facing rivets, are put together using tenon hinges. These stack together — the stacking parts are called charniers — and get secured using a vertical screw. Rivets are then driven into the frame following the tenons’ formation — they’re the decorative items you see on the front (leaves, arrows, bars, etc.)

    Rivets are clustered in sets of two or three, meaning eight or 12 in total. There are a set on either side of the frame when you’re looking at them straight on and sets on both arms, by the temples. Some come barred together, hence why you’ll see a rectangular plate out front instead of disconnected dots. Others use the tradition as a form of decoration. Their frames don’t need rivets at all, but their presence implies a polished finish — and quality craftsmanship — even if they’re the cheapest pair you could find.


    These keep the front of the frames (which hold the lenses) from falling off your face. In most glasses, they are the long shaft that stretches to the ear and is connected to a temple tip that curves behind the ear (holding the glasses in place).


    Sunglasses aren’t always sold sized, meaning they come without an official small, medium or large. Instead, they’re sold based on their width in millimeters. So, here’s a good gauge: 40-48 mm (small), 49-54 mm (medium), 55-58 mm (large), 58 mm+ (extra-large). For context, Ray-Ban’s Original Wayfarer is 50 mm wide.

      Round Faces

      What It Looks Like

      A round face shape implies your dimensions are roughly equal up and down and across. Plus, your jawline is soft, and your cheekbones are wide.

      What to Wear

      Stay away from circles, unless you want to over-accentuate the round shape of your face. Aim high with aviators or stick to square, angular frames.

      Ray-Ban Aviator Classic

      Oval Faces

      What It Looks Like

      The oval face shape is characterized by dimensions that are longer than they are wide — but not drastically so. You’re an oval if your face is longer than it is wide and your forehead is wider than your jawline.

      What to Wear

      It’s hard to go wrong with an oval face — most sunglasses will look great on you. Just make sure the frames aren’t wider than your face. “

      Square Faces

      What It Looks Like

      The square face shape, like the round, is defined by nearly identical measurements all around — with one exception: your jawline is sharper and your sides straighter.

      What to Wear

      Rounded corners are key to success if you’ve got a square jaw. Look for frames sized to match you in width, but with soft lines. Too many hard angles won’t do you any favors.

      Sunglasses for Square Faces

      Huckberry Cruisers

      Huckberry’s in-house sunglasses are a good pick. Why? They’re polarized; you can get two pairs for $60 dollars; and they fit snugly so they won’t fall off your face.

      Cubitts Herbrand Sunglasses

      These circular frames by Cubitts – called Herbrand — will cut up even the boxiest of faces. Plus, the keyhole bridge is cool looking, and the translucent green acetate frame goes well with most outfits.

      Sunski Yubas

      Like Huckberry’s in-house line, Sunski sunglasses are also fairly affordable — but they hold their own. The lenses are polarized, while the frame is made from 100 percent recycled materials. That makes them lightweight and flexible, thus less likely to break.

      Oblong Faces

      What It Looks Like

      The oblong face shape lends a long, vertical look. Here, the dimensions going up and down are undoubtedly more so than those going side to side.

      What to Wear

      Similar to our square-faced friends, you want to go with softer lines and rounded corners. Wayfarer styles work well but avoid small frames.

      GLCO Hampton Sun

      One of Garrett Leight’s best-selling frames, the Hampton Sun is a summer signature. It comes in 9 colorways, each with a cured cellulose acetate frame and a stainless steel core wire, UV protective lenses and real rivets.

      Heart Shaped Faces

      What It Looks Like

      A heart-shaped face means your cheeks and forehead are wider than your jaw, which proves pointed.

      What to Wear

      Square frames complement a narrower chin, adding different angles that add a layer visual of visual interest. Avoid anything oversized or teardrop shaped, and reach instead for something with a sharper corner.

      Diamond Faces

      What It Looks Like

      Just like a diamond, this face shape proves wide at the middle — across the cheekbones — but pointed at the forehead and jaw.

      What to Wear

      Most frame shapes will work well for diamond faces, so long as they’re in keeping with your proportions. Anything wider than your cheekbones will make the widest point of your face appear even wider (and, in turn, make your chin and forehead appear smaller than they actually are).

      Moscot Lemtosh Sunglasses

      The Lemtosh is a perennial favorite and a staple for family-owned brand Moscot. It’s been spotted on the faces of celebs like Johnny Depp, but you can rock it just as easily.

      Triangular Faces

      What It Looks Like

      For those with a triangular face shape, the forehead is the widest part. The rest leads into the chin, which is pointed, and accentuated by an angular jawline.

      What to Wear

      Frames with more going on up top are your friend. Anything teardrop-shaped will emphasize dimensional balance. Square frames with deep lenses are simple and effective.
