If you have a wide face or a big head, look first at total frame width. If standard glasses feel tight, that usually means looking for frames around 145 mm wide or more, with temples of 145 to 150 mm. Rectangular, square, aviator and oversized styles come in these sizes most often.
Below we cover how to tell when a frame is too narrow, which numbers to check, how to measure a pair that fits and what changes with a strong prescription. We also compare 13 Youtop frames using the measurements listed for each one.

Signs Your Glasses Are Too Narrow
If you have worn slightly small frames for years, the discomfort can start to feel normal. Watch for these signs:
- Pressure at the temples that builds through the day.
- Red marks or dents at your temples or behind your ears when you take the glasses off.
- Flared hinges. Seen from above, the temples angle outward from the hinges instead of running straight back. This strains the hinges and can loosen screws.
- A bowed front. Acetate fronts under constant pressure can flatten, changing the lens angle.
- Eyes near the outer edges of the lenses. Your pupils should sit roughly mid-lens or slightly toward the nose, not close to the outer rims.
- Glasses pushed up or forward on your nose, especially when the temples are also short.
- Headaches. Constant pressure can contribute to headaches for some people. Headaches have many causes, including an outdated prescription, so book an eye exam if they continue after the fit is fixed or come with vision changes.
For the opposite problem, frames that slide and stick out past your face, see our companion guide, How to Choose Glasses for a Small Face. The method is the same: measure first, then choose a style.
What Size Glasses Fit a Wide Face?
The key number is total frame width: straight across the front, from the outer edge of one hinge or end piece to the other. Lens width alone can mislead, because two frames with the same lens can differ by 10 mm or more overall depending on the bridge, rims and hinges.
Brands define sizes differently, but adult frames around 135 to 142 mm are usually called medium, roughly 145 mm and up is usually considered wide, and 150 mm or more extra wide. Treat these as starting points. A pair that already fits is the best reference.
| Measurement | Typical medium frame | Wide face or big head | What to watch |
|---|---|---|---|
| Total frame width | About 135–142 mm | About 145 mm and up | Front roughly as wide as your face at the temples |
| Lens width | About 49–54 mm | Often 54 mm+, not required | Bigger lenses are thicker for strong prescriptions |
| Bridge width | About 16–20 mm | Set by your nose, not face width | Too narrow pinches; too wide slides |
| Temple length | About 140 mm | 145–150 mm | Short temples pull behind the ears |
Face width and head size are not the same thing. A broad face can sit on an average head, and an average face can sit on a long head, which mostly shows up as temples that feel short. Check both total width and temple length.
How to Measure a Pair That Fits
Measuring glasses you already own is the most reliable way to size new ones. Use your most comfortable pair and a millimeter ruler.
- Read the arm. Inside one temple you will usually find three numbers such as 56-18-145: lens width, bridge and temple length. Our guide to the numbers on your glasses explains each one.
- Measure total width. It is rarely printed. Fold the temples, lay the glasses face down and measure across the front at the widest point, hinges included.
- Measure a temple if the print is worn off, from the hinge screw to the tip, following the bend.
- Adjust for how it feels. If the pair is slightly tight, aim 3 to 6 mm wider overall. If the temples pull behind your ears, try 5 mm longer. These are rough guides, not formulas.
- Compare with listings in this order: total width, temple length, bridge, lens. Our Eyeglass Frame Size Guide shows where each number is measured.
No glasses to measure? In a mirror, hold a ruler across your face at eye level and read the distance between your temples, just in front of the tops of your ears. A frame at that width or a few millimeters wider is a reasonable starting range.
Lens Width, Bridge and Temple Length
Lens width
Wide lenses (55 mm and up) are the obvious way to make a frame wider, but not the only one. Some frames get their width from a wider bridge or end pieces that extend past the lenses. If your prescription is strong, that difference matters.
Bridge width
A wide face does not automatically need a wide bridge. Bridge fit depends on your nose. If your current glasses sit well on your nose, keep the bridge within a couple of millimeters and find the extra width elsewhere. Adjustable nose pads on metal frames are the easiest to fine-tune.
Temple length
This is where people with larger heads most often go wrong. The temple must reach past the top of your ear before it bends. Too short, and the bend presses on your ear or the tips dig in behind it. Start at 145 to 150 mm, and check this number on every listing, since many frames list 140 mm.
Tip: Between sizes? Choose the wider frame and the longer temple. Temples can usually be bent in for a closer fit, but a frame that is too narrow can be eased out only slightly.
Shapes and Frame Details That Work
Any shape can come in a wide size, but these styles reach 145 mm and beyond most often:
- Rectangular: spans a broad face without much height, a classic office choice. Browse rectangle frames.
- Square: chunky acetate and 80s-style metal squares are often cut generously, and the extra lens height balances a strong jaw. See square frames.
- Aviator: wide by design, often with a stabilizing double bridge. See the pilot collection.
- Oversized: on a wide face, an oversized frame often simply fits. Start with our oversized glasses, checking each total width and temple length.
Details count too. End pieces that sit outside the lens add width without bigger lenses. Straight temples that curve late press less behind the ears. Spring or flex hinges, where a frame's description lists them, let the arms open a little past their normal stop, which helps a frame that is almost wide enough but cannot replace the right size. Sturdy rims and double bridges resist being spread better than delicate fronts.
Can Glasses Be Adjusted Wider?
A little. Adjustment can relieve pressure, but it cannot turn a 138 mm frame into a 148 mm one.
- Metal and titanium: temples can usually be bent outward slightly and reshaped behind the ear. Titanium is springy, so it takes more care. Adjustable nose pads can also change where the frame sits.
- Acetate: an optician can usually warm it and ease the temples or front out a few millimeters. Overheating can damage the frame, so avoid trying this with a hair dryer at home.
- Wood and very thin fronts: generally allow little adjustment. Buy these at the right width.
Many local optical shops will adjust frames bought elsewhere, sometimes for a fee. Our page on choosing the right frame material compares materials in more detail.
Wide Frames and Strong Prescriptions
Bigger lenses need more material. Nearsighted (minus) lenses get thicker toward the edges, and farsighted (plus) lenses need a thicker center as the lens gets larger. Either way, the lenses get heavier, and heavier glasses slide more. The fix is to get width from the frame, not the lenses:
- Pick a moderate lens with a wide total. Briar lists a 49 mm lens, a 150 mm total width and 150 mm temples, so it fits a wide head with less lens material than a 60 mm lens.
- Compare lens width plus bridge with your PD. A 61 mm lens and 18 mm bridge put the lens centers about 79 mm apart. With a 64 mm PD, each optical center shifts about 7.5 mm toward the nose, which adds edge thickness to minus lenses. Wide faces often come with wider PDs, but not always.
- Choose acetate to hide edges. Thicker rims conceal more of a thick lens edge than thin metal.
- Match the lens index. We recommend 1.56 up to ±2.00, 1.61 for ±2.00 to ±5.00, 1.67 for ±5.00 to ±7.00 and 1.74 above ±7.00. With a large frame, consider one step thinner. See 1.56 vs. 1.61 vs. 1.67 vs. 1.74 lenses.
For more on this, read How to Choose Glasses for a High Prescription. One upside of larger frames: if you wear progressives, a deeper lens leaves more vertical room for the distance, intermediate and reading zones.

Frequently Asked Questions
What size glasses do I need for a wide face?
Start with total frame width. Many people with wide faces do best around 145 mm or wider, and some need 150 mm or more. Measure a pair that fits and look for frames within a few millimeters of it, or slightly wider if that pair feels tight.
How do I know if my glasses are too small for my head?
Typical signs are pressure or marks at the temples or behind the ears, hinges that flare outward, eyes near the outer edges of the lenses and glasses pushed up or forward. If headaches continue after fixing the fit, have your eyes checked.
What temple length is best for a big head?
Usually 145 to 150 mm. The temple should reach past the top of your ear before bending, without the tips pressing into your head.
Can tight glasses be stretched to fit?
Only a little. Metal and titanium temples can be bent outward, and acetate can be warmed and eased a few millimeters, which may relieve pressure. A frame that is clearly too narrow needs a wider size.
Do wide faces need a wide bridge?
Not necessarily. Bridge width depends on your nose. Keep it close to one that already sits comfortably and get the extra width from the lenses or end pieces.
Are big frames bad for strong prescriptions?
They make lenses thicker and heavier, but you can manage it: choose a moderate lens width, keep lens width plus bridge close to your PD, consider acetate rims and pick a higher-index lens.
Quick Checklist Before You Order
- Measure the total width of your best-fitting glasses; go a few millimeters wider if they feel tight.
- Look for roughly 145 mm or more, and 150 mm or more if most frames pinch.
- Choose 145 to 150 mm temples for a larger head.
- Keep the bridge close to one that already sits well.
- With a strong prescription, favor moderate lens widths and the right index.
- Have your PD and current prescription ready for the lens step.
