Glasses for big heads: how wide is wide enough?

If most glasses pinch the sides of your head, leave marks above your ears, or make the arms bow outward, the front of the frame is probably too narrow for you. A bigger lens number alone does not fix that. What matters first is the total width across the front, and then the length of the arms.

Signs a frame is too narrow

Steady pressure at the temples is easy to mistake for a secure fit. If you notice it, compare wider frames, or ask an optician to adjust the arms.

Look for total width, not a size label

The three numbers printed inside the arm, such as 60-18-150, are lens width, bridge width and arm (temple) length in millimeters. None of them is the width of the whole front. Look for a published “frame width” or “total width” instead. Labels such as “wide” or “XL” are not standard: when we read two large stores' ranges in October 2026, one store's extra-wide frames measured 142–150 mm and the other store's XL frames 137–149 mm. If you own a pair that fits, measure its frame width and shop by that number.

What wide means in our catalog

FitMyFace lists 113 eyeglass frames from 9 online stores. Only 15 of them are wider than 150 mm, and they come from just 2 of those stores:

No frame from the other 7 stores in our catalog is wider than 150 mm. Choices for women are thin: above 150 mm there is 1 women's frame plus the 6 unisex ones. The widths are the stores' own published numbers, read in October 2026. Stock and prices change, so check the store before you buy.

Check arm length too

On a larger head the arms have further to reach. Arms that are too short press in front of or on top of the ears; arms that are too long let the frame slide forward. In our catalog, arm lengths run from 130 to 165 mm, and 28 frames have arms of 150 mm or longer. The 15 frames wider than 150 mm have arms from 140 to 165 mm.

FitMyFace does not measure where your ears are, so it cannot choose your arm length. Use the third number printed inside a pair whose arms feel right, and ask an optician whether a new frame's arms can be adjusted.

Try the widest frames on your own face

The free scan estimates your face width on your phone and ranks frames mainly by how close their width is to your estimated best width, so a wide face brings the wide frames forward. When enough frames are close, the list shows only those within about 10 mm of your estimated best width, so a very wide frame may not appear on a narrower scan. The scan also gives a range of frame widths to look for at any store. It uses your iris as a ruler, so its numbers are approximate: treat them as a starting point, and let an optician confirm prescription and final fit.

Before you buy: check the current price, stock, delivery time and return terms directly with the store. FitMyFace is free, has no affiliate links and is not the seller. The on-face drawing is an approximate preview, not a product photo.

Questions

Is 150 mm wide enough for a big head?

It depends on your head, not a label. If the best-fitting pair you own measures 148 mm and still presses, look a few millimeters wider. If it fits well, stay close to that number.

Can an optician make my current frames less tight?

Often the arms can be adjusted so they press less. Plastic arms usually need heat to bend safely, so do not force them yourself; they can crack.

Will my photo leave my phone?

The glasses scan runs on your device. The optional AI hairstyle preview is a separate feature. For the optional AI previews, your consent is the one "I agree" on the scan screen, which says your photo is sent to Cloudflare for them, and a switch on the results turns them off. FitMyFace is for adults 18 and over and is not available in Illinois.
