Glasses for Narrow Faces: Measure Your Frame Width in 3 Steps

Your glasses sit wider than your face, and the arms flare out like open doors. Your head isn't the problem. The frame width is.

Glasses for narrow faces should have a total frame width close to your face width at the temples, typically 125-135 mm, with lens widths of 44-49 mm and a bridge of 16-19 mm. Pick a frame that is level with, or a few millimetres inside, your temples. The lenses then sit centred on your eyes and the arms run straight back to your ears.

How do you measure a narrow face for glasses?

Read the three numbers printed inside the temple arm of a pair that already fits you, then measure your face across the temples with a ruler. A code such as 47-18-140 means lens width 47 mm, bridge 18 mm and temple length 140 mm. Most product pages also list the total frame width separately. A frame suits a narrow face when its outer edges end level with, or slightly inside, the widest part of your face at the temples. If the rims stick out past your temples, the frame is too wide, and no amount of bending will fix that. Check it in a mirror, face forward, with the ruler held across the frame. It takes two minutes and can save you a return.

1. Hold a ruler flat across your face at temple level and note the width in millimetres.
2. Turn over your best-fitting current pair and write down the lens, bridge and temple numbers.
3. Compare both with the frame width listed on the product page, and discard anything that overhangs your temples.

What frame size fits a narrow face?

For most narrow faces, aim for a total frame width of roughly 125-135 mm, lens widths of 44-49 mm and a bridge of 16-19 mm. Many standard adult frames run wider, around 135-145 mm, so they overhang a narrow face and push the lenses away from the centre of your pupils. Temple length is the least affected measurement. Most heads are covered by 135-145 mm, so choose it by how far your ears sit behind the hinge, not by face width. If you fall between two sizes, take the smaller one. A snug frame can be adjusted slightly, while an oversized one can't be made smaller.

Measurement	Typical range for narrow faces	What it controls
Total frame width	125-135 mm	Whether the frame overhangs your temples
Lens width	44-49 mm	Lens size and edge thickness
Bridge width	16-19 mm	Fit on the nose and alignment with your PD
Temple length	135-145 mm	Grip behind the ears

Which frame shapes make a narrow face look balanced?

Small ovals, slim rectangles and softly squared frames keep the width in proportion with a narrow face. To make the face read a little wider, choose frames with visual weight at the outer corners: a browline, a gentle cat-eye lift or detail on the temple arms. Avoid very tall lenses, which stretch a long, narrow face further. Round frames work only when they are genuinely small, with lens widths around 44-47 mm. Larger rounds overhang almost immediately. Our opinion: a lighter-toned or patterned front looks better on a narrow face than a thick, solid black one, which tends to dominate it.

• A patterned acetate such as ClarityEdge-Tortoiseshell breaks up the frame front visually, so it feels lighter on a narrow face.
• A slim metal frame such as Liberty Gold adds almost no bulk at the sides. Check its listed width against your measurements first.
• Titanium and flexible memory metal frames come in thin profiles, and their arms spring back after being flexed, which helps on a tight fit.

Another option is Lava. Open its page and test the lens width and bridge numbers against yours before you decide.

Does a narrow face change your lens thickness and PD?

Yes, because narrow faces often come with a smaller pupillary distance (PD), and a frame that is too wide forces the lenses to be shifted off-centre, which makes them thicker at the edge. Adult PD typically falls between 54 and 74 mm. To get a frame's own PD, add its lens width and bridge width: a 50 mm lens with an 18 mm bridge gives 68 mm. If your PD is 58 mm, that 10 mm gap means each lens is decentred by about 5 mm. In a minus prescription the outer edge then ends up noticeably thicker, and the lab needs a larger lens blank to cut it. A frame whose lens width plus bridge lands within a few millimetres of your PD keeps lenses thinner and the optics better centred.

Most people overlook this: lens width isn't the only number to match to your face. Lens width plus bridge should also match your PD. It's the quickest way to get thinner lenses without paying for a higher index.

For stronger prescriptions, a higher index also helps. We'd look at 1.61 or 1.67 for moderately strong prescriptions and 1.74 for very strong ones. An anti-reflective coating is worth adding on thinner, higher-index lenses. If you're unsure of your PD, ask your optician to measure it, or check your prescription, where it is often listed.

Why do glasses slide or pinch on a narrow face, and how do you fix it?

Glasses slip or pinch on a narrow face mainly for three reasons: a bridge wider than your nose, a frame front wider than your face, and arms that splay outward instead of running straight back. Fix the cause, not the symptom. Choose a bridge in the 16-19 mm range, and check that the rims end within your temples. Metal and titanium frames with adjustable nose pads let you narrow the contact points on your nose, while acetate frames rely on a fixed bridge, so that number matters more. If the arms point outward, the frame is probably too wide. Bending them inward only helps a little, because the hinges still sit too far out.

Quick checks when your new pair arrives:

• Shake your head gently. The frame should stay put without leaving deep marks on your nose.
• Look straight ahead. Your pupils should sit near the centre of each lens.
• Check the arms from above. They should run close to parallel, not fan out.
• Smile. If the frame lifts off your cheeks, the lens height or the angle of the frame is wrong.

Pairs such as Isabella are worth a look if you prefer a more delicate front.

Frequently Asked Questions

What counts as a narrow face for glasses?

It's a face whose width across the temples is smaller than the width of standard adult frames. If frames of 135 mm or more overhang your temples and the arms splay outward, you probably have a narrow face in frame terms, however your face shape is classed.

Can I wear standard-size frames if I have a narrow face?

Sometimes, if the lens width is small and the bridge fits. But a frame front wider than your temples will always look and feel oversized. Compare the listed frame width with your own measurement before you order.

Is titanium better for a narrow face?

Titanium is also corrosion-resistant and hypoallergenic. It doesn't fix a frame that is too wide, though, so check the measurements first.

Do narrow faces need a different lens index?

Not because of face width alone. The index depends on your prescription strength and on how far the lenses are decentred. A frame with a lens width plus bridge close to your PD keeps lenses thinner, and for stronger prescriptions 1.61 or 1.67 is a sensible step up from 1.56. For anything medical or measurement-related, ask your optician.
