Frame size is determined by the three key measurements found inside the frame arm: lens width (from 31-60mm), bridge width (from 12-31mm), and arm length (from 115-155mm).

Lens height is essential for multifocal prescriptions, such as Progressives, which require a minimum measurement of 28-30mm. They are also recommended for Rx sunglasses.
These wide rectangular frames from 7 For All Mankind suit round chins, soft features, and wider foreheads. A very slight keyhole bridge adds retro flare for longer, wider noses while slim frame arms come equipped with flexible spring hinges to fit medium faces.
