If you already own a pair of glasses that have a similar shape to the frames you are interested in (e.g., angles), you can use them to help you determine the right width for your face shape. Simply use a standard ruler and measure along the top of the frame from the furthest point to the other.
Note: Not all models are available in all sizes. This should not be a big problem, as your favorite frames may deviate up to ± 2 mm from the actual width. In the case of sunglasses, the range is even wider since they generally tend to be worn a little larger.
If you wear angular frames with a width of 138 mm, you can be sure that virtually any angular glasses with a width of 136 to 140 mm will fit comfortably.
Is the width of my glasses indicated on the frame?
Unfortunately no, the width of a pair of glasses is not written on the frame. The width must be measured with a ruler.
