If you have a long face size, your face is longer than it is wide. It is typically very symmetrical, but the wrong frames can elongate the length of your face even more than you want. You'll want to choose frames that are larger to break up the length of your face. Try taller, squared-off or more circular frames, which will take up more room on your face and help balance out your features better than oval or rectangular frames. Also look for glasses with thicker arms or decorative details at the temples, since they will draw attention to the sides of your face and make it appear broader.
