Glasses Measurements & Frame size

Finding the right frame size is a super important part of buying eyewear online. But did you know it's also super simple? We created a helpful guide to make the process quick and easy. Here’s what you need to know when looking for your eyeglasses and sunglasses frame measurements. To ensure your frames fit perfectly, first determine which size frames are best for you. The best place to start is with the eyeglass measurements on a pair you already own. First, search for the three little numbers on the inside of the temple of your glasses. Some may also refer to this section as the "arm" of your glasses. These three numbers are the frame's measurements.

01

Lens Width

This is the horizontal width of each lens at its widest point. It typically ranges from 40mm to 60mm.

02

Bridge Width

This is the distance between your two lenses. In short, the bridge width is the space where your frames fit against your nose. The size of this piece ranges from 14mm to 24mm.

03

Temple Length

This is the length of the temple from each screw to its temple tip, including the bend that sits on your ear. The temple is typically 120mm to 150mm long.
