Best sunglasses for your face shape

The best sunglasses balance your face shape. A round face needs corners, and a square face needs curves.

Four SpecFit try-ons: rectangle, cat-eye, browline and aviator sunglasses on two people — Four sunglasses styles, tried on in SpecFit. Each one suits a different face.

Find your face shape first

Look at your face in a mirror. Pull your hair back.

Check three things:

Length: is your face longer than it is wide?
Widest part: is it your brow, your cheeks or your jaw?
Jaw: is it soft and curved, or straight with corners?

Sunglasses for a round face

A round face is about as long as it is wide. It has soft curves and no sharp jaw corner.

Pick: square or rectangle sunglasses.
Why: straight lines add the corners your face does not have.
Avoid: small round lenses. They make the face look rounder.

Sunglasses for a square face

A square face has a wide brow and a strong, wide jaw. The jaw runs almost straight down to a flat chin.

Pick: round or oval sunglasses. A soft cat-eye works too.
Why: curves soften a strong jaw.
Avoid: hard square frames. They repeat your jaw line.

Aviators suit a square face too. See aviators for a square face and glasses for a square face.

Sunglasses for an oval face

An oval face is a bit longer than it is wide. It is widest at the cheeks and gets narrow at the chin.

Pick: almost any shape. A cat-eye is a good start.
Why: the face is in balance, so most frames look right.
Watch: a plain frame can look dull. Lifted corners add life.

Long face sunglasses

A long face is clearly longer than it is wide. It often has a high brow and a straight, narrow jaw.

Pick: deep frames with a strong top bar. Try a browline or a navigator.
Why: a bold line across the face breaks up the length.
Avoid: small, narrow lenses. They make the face look longer.

Sunglasses for a diamond face

A diamond face is widest at the cheekbones. The brow and the jaw are both narrow.

Pick: rimless or thin metal sunglasses.
Why: a light frame adds no bulk to wide cheekbones.
Avoid: thick frames that are widest at the cheeks.

Sunglasses for a heart face

A heart face has a wide brow and wide cheeks. It gets narrow at a small, pointed chin.

Pick: aviators, or other frames that are wider at the bottom.
Why: width low on the frame balances a narrow chin.
Avoid: heavy top bars. They make the brow look wider.

Size matters more than shape

The right shape still looks wrong in the wrong size. Check the fit first.

Width: the frame should be about as wide as your face.
Top bar: it should sit at your brows, or just cover them.
Eyes: they should sit near the middle of each lens.
Cheeks: the lenses should not rest on them when you smile.
