Square Face: A square face features a prominent jaw line, wide forehead, and angular features like the chin and cheekbones. The length and width of a square face are roughly the same.
Frames: Look for frames that make the face appear longer. Minimal or thinner frames with soft, round lines will look best. Oval and circular frames work well, as do neutral colors.
Round Face: A round face has similar width and length, like a square face, but has much softer angles in the cheeks and chin. Cheeks are typically full and the chin is rounded.
Frames: Select frames that elongate the face. Typically this means rectangular frames. Frames with nosepads will help raise the glasses above the cheeks, and high temples may help slim the face as well. Round frames should generally be avoided.
Oval Face: The oval face is the most common, characterized by overall balance. The chin is slightly more narrow the the forehead and cheekbones are typically high.
Frames: Most frames work for an oval face, so that provides the freedom to find a style you enjoy. Bold shapes and colors can add personal style to your frames. The goal is to maintain the natural balance of the face. Frames should be broader than the widest part of the face. The eyes should not be too close to the top or bottom of the glasses.
Heart Shaped Face: A heart face has a wide forehead, narrow chin, and high cheekbones. The jaw line may be narrow as well.
Frames: A difficult face to frame, look for frames that are wider than the forehead. Frames that are wider on the bottom, and have details on the lower half, often work well. Light colors can look best, and be sure to consider rimless frames as well. Some people prefer rounder frames, so be sure to consider all of your options.
