Sunglasses for Your Face Shape: A Guide for All 7

Sunglasses follow the same contrast rule as glasses: round faces suit angular wayfarer, rectangular and cat-eye shapes; square faces suit round, oval and aviator lenses; oblong faces suit oversized and deep frames; heart faces suit bottom-heavy aviators and round frames; diamond faces suit cat-eye and oval frames; triangle faces suit top-heavy browline and cat-eye frames; and oval faces suit almost anything. Always check for UV400 or 100% UV protection.

The Contrast Rule

Choose sunglasses that contrast your face's outline: angles for soft faces, curves for angular ones, depth for long faces, and width at whichever part of the face is narrowest. Size matters as much as shape; the frame should be about as wide as the widest part of your face.

Sunglasses for Each Face Shape

Oval: almost anything, from aviators to oversized frames. Round: wayfarers, rectangular and cat-eye shapes add angles; avoid small round lenses. Square: round, oval and aviator lenses soften the jaw; avoid boxy frames. Oblong: oversized, deep frames shorten a long face; wraparound and decorative arms add width.

Heart: aviators, which are wider at the bottom, and round frames balance a wide forehead. Diamond: cat-eye and oval frames soften wide cheekbones. Triangle: browline and cat-eye frames add width at the top to balance a wide jaw.

What to Check Before You Buy

UV protection: look for UV400 or '100% UV protection'. Dark lenses without UV protection can be worse than none, because your pupils open wider behind them. Polarised lenses cut glare from water and roads, useful for driving and the beach. Fit: the frame shouldn't touch your cheeks, and your eyes should sit near the centre of each lens.

Frequently Asked Questions

How do I choose sunglasses for my face shape?

Contrast your outline: angular frames for round faces, curved frames for square faces, deep frames for long faces, and wider frames where your face is narrowest.

What sunglasses suit a round face?

Wayfarers, rectangular and cat-eye frames, which add angles. Avoid small round lenses.

What should sunglasses have for eye protection?

UV400 or 100% UV protection. Polarisation reduces glare but isn't the same as UV protection.
