Choosing a frame for your face

These are conventions, not rules, and plenty of people look better breaking them. Use the face-shape filter as a starting point rather than a verdict.

Round or full face

Angular shapes give definition. Look at the square and cat-eye frames, and avoid small round lenses which echo the face shape.

Square or strong jaw

Curved frames soften. Round and oval shapes work, as do aviators with a gentle drop at the outer edge.

Oval

Almost anything sits well. Choose by lens width instead: the frame should end within a few millimetres of your temples.

Long or narrow

A deeper lens shortens the face visually. Square and aviator shapes with a taller front are the reliable picks.
