A square face is characterized by defined angles and roughly equal lines at the forehead, cheeks, and chin. A rounded frame is highly attractive on this face shape.
A round face has roughly equal width and length. A square or rectangular frame looks excellent on this face type by elongating the face and reducing the appearance of full cheeks.
A heart-shaped face is characterized by a narrow chin and a tapered forehead. A larger frame looks great on this face shape.
An oval face generally has higher cheekbones and a chin that is only slightly narrower than the forehead. Oval faces look good in nearly every frame shape, but frames with upward angles compliment high cheekbones and slim the wearer’s jawline.
