A simple rule: contrast your face shape with your frames. Round faces suit angular or rectangular sunglasses, square faces suit round or aviator styles, heart-shaped faces suit bottom-heavy or aviator frames, and oval faces suit almost anything. Fit matters more than any rule: the frame should be about as wide as your face, sit level and not touch your cheeks.
The right sunglasses balance your features and fit comfortably. Use face shape as a starting point, then let fit and personal style decide.

Common questions
How do I find my face shape?
Pull your hair back and look straight into a mirror. Compare the width of your forehead, cheekbones and jaw, and the length of your face. Round faces are about as long as wide with soft angles; square faces have a strong jaw; oval faces are longer than wide; heart-shaped faces are wider at the forehead.
What sunglasses suit most faces?
Aviators and classic rectangular styles with slightly rounded corners suit the widest range of face shapes.
What size sunglasses do I need?
Choose a total frame width close to your face width, and use the lens width, bridge and temple numbers from glasses that fit you as a guide.
