Frame size is determined by the overall width of a frame. We measure the width of our frames from hinge to hinge on the inside of the temples.

You can find your fit using a measuring tape or ruler. Hold the ruler along the bottom of your forehead, right above the eyes, from temple to temple. Make sure the ruler doesn't bend. Use this number to find your frame size. You will be able to shop slightly narrower and wider than your size.
