Our Frames are sized according to lens width, nose bridge distance & temple (arm) length 

When ordering online it is a good idea to check what your current frame size is. typically you will find 2 numbers on the temple (arm) that look like this: 52[]19. these numbers tell you the width of the lens and the distance between lenses respectively. Overall width and temple (arm) length are not generally not shown, but you can measure these using a ruler. 

The sizings for each frame are given alongside the frame description on the relevant pages
