Do your sunglasses leave red marks behind your ears by lunch? Do they slide off the second you glance down? Then the frame is simply too small for your head. That is a fit problem rather than a style problem, and it is far easier to resolve than most people assume.

A wider face and a bigger head really need two things: a wider frame front, and temples with room to spare. Get that pairing right and the style takes care of itself. The Foster Grant sunglasses below are built for exactly that. You will find expanded-temple aviators, oversized shapes, and fits-over pairs you can bend to your own head.

Three things decide whether a frame fits a bigger head, and none of them is the logo printed on the temple. Get these right and almost any shape will feel comfortable throughout the day.

Start with frame width. The front should be as wide as the widest part of your face. That way the temple arms clear your cheeks instead of digging into them. A frame that sits too narrow is the usual reason behind pinching and those end-of-day marks.

Next, consider the temple arms themselves, because long or expanded temples wrap a larger head without squeezing it. Temples you can adjust yourself, like Foster Grant's BendToFit® design, let you fine-tune the grip until it disappears. Adjustable nose pads help here too, since they keep the frame from sliding down.

Last comes proportion, since big, bold shapes hold their balance on a broad face (a strong square, a wide rectangle, an oversized round). Very small frames simply tend to look lost and perched.

Every pair below also carries 100% UVA-UVB lens protection. So a better fit never costs you sun protection.

Maybe your head just needs a little more room than most frames provide. If so, begin with Foster Grant's Styles for Y.O.U.™ range, and specifically the pairs with a Low Bridge Fit and Expanded Temples. That expanded-temple design is made for people who want extra space in their sunnies, which is the wide-face brief in one line.

Toronto is the aviator of the two, an Acetate frame in crystal blue with subtle metal accents at the corners. The smoke grey lenses give you 100% UVA-UVB lens protection, the expanded temples add width across your head, and the low-bridge shaping suits higher cheekbones. Toronto's frames are also made with 50% recycled plastic (recycled content is calculated by mass balance), so the roomier fit comes with a lighter footprint.

Want a more classic, everyday look? San Fran runs the same expanded-temple fit in a way-style shape, pairing a rich tortoise Acetate front with smoke grey 100% UVA-UVB lenses. You get the same room across the head, only in more of a wayfarer feel, so between these two you are really choosing a shape rather than a fit. For even more adjustability, the gold-toned Dubai aviator from the same range adds adjustable nose pads for extra comfort when you need it.

If standard frames seem to shrink on your face, it is time to scale up. Jersey City is an oversized square, and that extra size is precisely the point, because a larger lens fills out a wider face instead of getting swallowed by it. The front is layered crystal-clear and shiny black Acetate, so it reads bold without shouting.

The smoke grey lenses carry the same 100% UVA-UVB lens protection as the rest of the range. Like the other Styles for Y.O.U.™ frames, Jersey City is made with 50% recycled plastic (mass balance). A square front also introduces a little structure to the face, which plays nicely against softer, rounder features.

Not every wide face wants a hard-edged frame. If yours carries a strong jaw or high cheekbones, a rounder shape softens those angles, and going oversized keeps the proportion right. The 1970's manages both at once. It is a big, out-front round frame in silver-toned metal, with a warm rose-colored lens.

This one is a statement. It also protects the way a Foster Grant should, with 100% protection from the sun's UVA-UVB rays. Each pair ships with its own micro-fiber pouch and a protective carrying case. That is handy for a larger frame you will not want to toss loose in a bag.

Do you wear prescription glasses under your shades? Then a fits-over pair is often your smartest move. It is built roomy by design. And it skips the frame-width guessing.

The Haven® Summerwood sits over prescription frames up to 137 mm wide, which leaves genuine space for a larger head underneath. It is polarized, too, so the lenses carry a filter that cuts glare bouncing off water, roads, and other flat surfaces, alongside full 100% UVA-UVB lens protection. The amber tint helps improve depth perception and contrast, while side lenses add coverage right at the edges. Best of all for fit, the BendToFit® temples adjust to your head, not the other way around. You shape them once and they hold.

Prefer a squared-off look? The Haven® Hayes is a rectangular fits-over in the same roomy build. It also fits over frames up to 137 mm wide, with side windows for a modern edge. The Banyan brings a more classic shape, with side lenses for extra coverage and the same BendToFit® temples. All three use Haven's Optify™ lens technology, so none of them feels clunky on your face.

The quickest test is still the mirror. Put a pair on, look down, and shake your head gently. If the frame slides or the temples bite, size up. You can reach for expanded temples, or go fits-over. If it stays put with no pressure behind your ears, you have found your width.

After that, it is entirely about style, whether that means an aviator, a wayfarer, an oversized square, or a bold round. Browse the full sunglasses range, the men's and women's edits, or the fits-over and clip-on collection to find your size. Check the polarized styles, too, if you spend real time on the road or water. Ninety-five years on, The Original American Sunglass Brand® still believes a great pair should fit you, not the other way around.
