Hello Kristin, thank you for your interest in our product. The frame size is large with temple arms of 142. Unfortunately, this is fixed and cannot be customized. Choosing a perfect frame size online can be tough sometimes, here's what we can do for you: First, kindly check how to measure eyeglasses size and find the perfect size. You can also check the numbers on your old glasses that look like 51-18-135. The 1st is the width of one lens; the 2nd is the bridge distance, and the 3rd is the length of the temple piece that goes behind your ear. Thank s for your support. Stay safe!
