Thin vs Thick Temples: How Temple Width Changes Your Look

Thin temples make glasses look lighter and let your face, hair and earrings take the lead; thick temples frame the side of your face and make the glasses a visible part of your outfit. Neither is better for comfort by default. The right width depends on how strong your features are, how you wear your hair and how much of a statement you want the frame to make from the side.

Most people choose glasses by looking straight into a mirror, so the temples (the arms that run back to your ears) rarely get much thought. Yet half the time people see you in profile: across a table, on a video call at an angle, walking next to you. That side view is where temple width does its work.

What counts as a thin or a thick temple?

There is no official cut-off, but in practice frames fall into three groups:

• Thin temples are usually wire-like metal arms, often finished with plastic or acetate tips where they rest behind the ear. From the side they read as a fine line.
• Medium temples are the standard acetate arm on most everyday frames. Visible, but not the first thing you notice.
• Thick temples are wide acetate arms, sometimes with studs, rivets or a broad hinge block near the front. From the side they form a solid band from the lens to the ear.

Temple length is a separate measurement. The third number printed on the inside of a temple (for example 145) is the arm length in millimetres, and it decides whether the frame sits securely behind your ears. Width is about looks and feel; length is about fit. Our frame size guide explains how to check the length against a pair you already own.

How temple width changes your look

Think of the temple as the line that connects the frame to the rest of your head. A wider line draws more attention to that connection.

• Thick temples add weight to the side of the face. On a narrow or long face they can make the head look a little broader. On someone with strong cheekbones or a square jaw, they hold their own instead of looking flimsy.
• Thin temples open up the profile. Cheekbones, sideburns, earrings and the shape of a haircut stay visible. The overall effect is lighter and more understated.
• Thick temples make a frame look finished. A bold acetate front with skinny arms can look unbalanced; matching width front to back looks deliberate.
• Thin temples suit delicate fronts. Fine metal rims, rimless or semi-rimless frames usually come with thin arms for the same reason.

Thin vs thick temples at a glance

Matching temple width to your features and hair

A few practical pairings tend to work well:

1. Short hair or hair worn back: the temples are fully on show. Thin arms keep things neat; thick arms become a style feature, so pick a colour you like seeing.
2. Long hair worn down: most of the temple disappears behind your hair, so width matters less from the side. A thick temple can still add a nice line at the hairline.
3. Beards and strong jawlines: a wider arm balances the extra visual weight lower on the face.
4. Statement earrings: thin temples avoid competing with them.
5. Small or narrow faces: very wide temples can crowd the space between the eye and the ear. Medium acetate or slim metal usually feels more in proportion. Our face shape guide helps with the front of the frame.

Comfort: what width does and does not change

A thicker arm does not automatically mean a heavier pair. Acetate is light for its size: the Downey acetate frame weighs 25 grams and the Camet 28 grams according to their product pages. What you feel most is where the weight sits and how the arm meets your head.

• Contact area: a wide temple spreads pressure over a larger patch of skin, which many people find comfortable. A thin metal arm concentrates it on a smaller line, so its tips matter more.
• Headwear: if you wear over-ear headphones, a helmet or a snug beanie, try the frame with them on. Thin arms usually slide under more easily.
• Hinges: spring hinges, like those on Shellton, let the arms flex outward a little, which helps with a wider head.

Whichever width you choose, the arm length still needs to suit you. If a pair feels tight behind the ears, the length or the bend is usually the issue, not the width.

Details that make thick temples look intentional

Wide temples give designers room for small details that show up in profile: metal studs, rivets near the hinge, a contrasting pattern or a two-tone finish on the inner side. Shellton has rectangular studs on its temples, and the Downey frame carries its blue-green pattern all the way back along the arm, which is exactly what you see in the photo at the top of this guide. When you shop, look at the side-view photo as carefully as the front one; it shows how much frame people will see when you turn your head.

If you are torn between the two, a good middle ground is a metal frame with acetate temple tips, or a slim acetate frame from our acetate collection with a moderate arm.
