Find your perfect frame size
To determine if a frame is right for you, you first need to determine the frame size that works best for you.
First, measure the length of the temple that you feel will hang comfortably.
This dimension is usually the inside of the temple of the spectacle, which some people refer to as the "arm" of the spectacle. Frame sizes are usually displayed as three numbers separated by dashes, such as 49-22-150.
