Choosing the right frame size is essential when purchasing eyewear online, and fortunately, it’s quite simple! Below is a useful guide to understanding glasses measurements and sizes to help you find the perfect pair of eyeglasses or sunglasses.
To ensure a proper fit, start by identifying the frame size that suits you best. The easiest way to do this is by checking the measurements of a pair you already own and find comfortable.
You can typically find these measurements on the inside of the temple (or “arm”) of your glasses. They are usually displayed as three numbers separated by dashes, such as 48-19-140, each representing different frame dimensions.
From left to right, the numbers represent: A. Lens width B. Bridge width C. Temple length
Lens Width
This is the horizontal width of each lens, measured at its widest point. Also called eye size, it typically ranges from 40 mm to 60 mm.
Bridge Width / Distance between lenses
This is the distance between your two lenses. In short, the bridge width is the space where your frames fit against your nose. The bridge size ranges from 14 mm to 24 mm.
Temple (Arm) Length
This is the length of the temple from the hinge to the temple tip, including the bended part that sits on your ear. The arm length is typically 120 mm to 150 mm long.
