Glass Size Guide (in millimeters)

Glass sizes are expressed in millimeters (mm) and primarily refer to the lens width, a key measurement for ensuring a comfortable and aesthetically pleasing fit according to face size.

How to choose the right size?

• 50–52 mm → Small faces Recommended for thin or narrow faces. They offer a balanced fit without protruding from the face.

• 53–55 mm → Medium faces The most common and versatile size. Ideal for most medium-sized faces.

• 56–58 mm → Medium to large faces Provide greater coverage and a comfortable fit for wider faces.

• 59–60 mm or more → Large faces Designed for wide faces or those seeking a more wraparound style.

Helpful tip: If you already own glasses that fit well, you can check the size inside the temple and use it as a reference. When in doubt, a mid-size is usually the safest option.
