The zenni website shows the frame width (and other dimensions) in millimeters for each pair of glasses. I've ordered over a dozen of pairs over the last 3 years and the measurements are accurate. Measure the width of your current pair that you like. You're may be 150mm+ in width and zenni has sizes even bigger than that.
