How do you find glasses that fit a wide face?

Short answer

Measure your face at its widest point, usually just above the ears, with a tape measure or ruler. Compare that number to a frame’s total width, found from the three numbers stamped inside the temple arm (lens width-bridge width-temple length, in millimeters). A frame within about 2-3mm of your measurement on each side should sit without pinching at the temples or sliding down the nose.
  • Frame size is stamped inside the temple arm as three numbers in millimeters: lens width-bridge width-temple length.
  • Measure your face across the temples, not your current glasses, since an old pair may already fit poorly.
  • A true ‘wide’ or ‘XL’ size should widen the frame front and lengthen the temple arms, not just the lenses.
  • Spring hinges and flexible frame materials reduce pinching better than rigid hinges at the same stated width.
  • Check the seller’s return window before buying online, since fit varies frame to frame even at the same size number.

​
Start with your face, not your old glasses

The most reliable way to shop for a wide-face fit is to measure your own face before you look at a single frame. Stand in front of a mirror and measure straight across your face at its widest point, which for most people is just above or at the top of the ears, not at the cheekbones. A soft tape measure works best; a rigid ruler held flat against your face is a reasonable substitute. If you don’t have a tape measure, a standard credit or debit card is a useful reference object: it is 3.37 inches (85.6mm) long. Hold it against your face in a photo, or lay it next to a frame on a flat surface, to get a rough sense of scale before you commit to a purchase. Don’t measure your current glasses instead of your face. If those glasses already leave marks on your nose or press at the temples after a short time wearing them, they are part of the problem you’re trying to solve, not a reliable reference point.

​
Decode the numbers stamped inside the temple

Nearly every pair of glasses has three numbers printed on the inside of one temple arm, in a format like 52-18-140. In order, these are the lens width, the bridge width (the gap between the lenses, over the nose), and the temple length (the arm that runs back to the ear), all in millimeters. To estimate a frame’s total width, add the two lens widths to the bridge width: a 52-18 frame with two lenses is roughly 52 + 18 + 52 = 122mm across the front, though the exact figure depends on frame shape. Compare that number to your own face-width measurement. If the frame number is more than a few millimeters narrower than your face, expect pressure at the temples; if it’s noticeably wider, expect the glasses to slide or sit loosely. A seller who publishes these three numbers for a specific pair, rather than only a generic ‘small/medium/large’ label, gives you something you can actually check against your own measurement.

​
What a “wide” or “XL” size should actually change

Some frames are offered in a second, wider version of the same style. What that version should change is the frame’s front width and the temple length together, since a wider face is usually paired with a longer distance from temple to ear. A version that only widens the lenses without lengthening the arms can still end up feeling tight, because the arms have to bow outward to reach around a wider head. Before buying a ‘wide’ or ‘XL’ listing, check whether the seller states an updated set of all three numbers for that version, not just a note that says ‘fits larger faces.’ If only one number changed, or none are given at all, treat the wide-fit label as a guess rather than a specification.

​
Hinges and materials matter as much as width

Two frames with identical stated widths can fit differently depending on their hardware. A spring hinge, which lets the temple arm flex outward and return to shape, tolerates a face that’s a little wider than the frame’s resting width better than a rigid hinge does. Frame materials that flex, such as some plastics and flexible metal alloys, behave the same way: they spread slightly under gentle pressure instead of digging into the same two spots all day. Temple length is a separate variable from width and is easy to overlook. Even a frame that is comfortably wide enough can still feel wrong if the arms are too short, because the bend that rests behind the ear ends up pulling forward instead of hanging naturally. If a frame is available in more than one temple length, that measurement is worth checking independently of the width.

​
Confirm the return window before you buy online

Fit is the hardest thing to judge from a product photo, and stated measurements are still estimates once a frame is actually on a real face. Because of that, it’s worth confirming a seller’s return policy before you buy non-prescription eyewear online, especially the first time you order from a given brand, so an ill-fitting pair isn’t money lost. When a return is straightforward, use it: note where the frame presses or gaps after 15 to 20 minutes of normal wear, not just in the first few seconds in front of a mirror, since a fit that feels fine at first can turn uncomfortable once the frame has settled. A frame that still marks the skin or slides after that adjustment period is a fit problem worth returning over, not something to push through.
