The frame width should be slightly wider than your face but with the space between your temple and frame no larger than a finger’s width.
Moreover, you also should ensure the Arm Length is right for you. The arms of glasses should run along with your temple and wraps around your ears. The arms should run horizontally and sit comfortably around your ears only touching your head right before your ears. Of course, you can find the arms-length of glasses on the side of the temple.
