Other Useful Measurements

To find the best fit for your glasses, first you should look for the perfect <highlight>frame width</highlight>.

A frame that’s slightly wider than your face is a good place to start — no more than a finger width between the temple and your face is a good rule of thumb.

If you’ve already got a pair of glasses that fit, measure <highlight>from screw to screw</highlight> on the face front for a good idea of the frame width.

All frame measurements can be found in the <detail>details</detail> section of our product pages.
