Finding the right frame size is an important part of buying eyeglasses online. Luckily, it's pretty easy. Here's a guide to help you understand your eyeglass size and size when looking for eyeglasses and sunglasses.

Find your perfect frame size

To determine if a frame is right for you, you first need to determine the frame size that works best for you.

First, measure the length of the temple that you feel will hang comfortably.

This dimension is usually the inside of the temple of the spectacle, which some people refer to as the "arm" of the spectacle. Frame sizes are usually displayed as three numbers separated by dashes, such as 49-22-150.

Lens width

This is the horizontal width measured at the widest point of each lens. Also called eye size, it usually ranges from 40 mm to 60 mm.

Bridge width

This is the distance between the two lenses. In a nutshell, bridge width is the space the frame fits on your nose. Bridge sizes range from 14mm to 24mm.

Lens height

This is the vertical height of the lens. Measurements are taken at the widest point of the lens in the frame. Lens height is especially important when measuring bifocal or progressive lenses.

Temple length

The length from the temple hinge to the tip of the temple, including the curved part that touches the ear. Arm lengths are typically 120 mm to 150 mm.
