Measure the widest part of your face, temple to temple, using a soft measuring tape.
The three numbers inside your temple arm (e.g. 52-16-140) are lens width, bridge, and temple length in mm.
Compare your face width or current frame measurements to the size chart above.
Go with the larger size for a relaxed fit, or smaller for a snug, sporty feel.
