How do I know my frame size?

Determining your frame size is an important step for selecting the right eyewear and ensuring a comfortable fit. Generally, frame size is indicated by three numbers found on the inside of the temple arm of the eyeglasses. These numbers represent the width of the lenses, the width of the bridge, and the length of the temple arms, measured in millimeters. The first number is typically the horizontal width of the lenses, the second is the distance between the lenses across the bridge of the nose, and the third is the length of the side arms that go over the ears. If your current pair of glasses does not have this information, you can also measure your face. Start by measuring the distance between your temples to gauge the frame width that will likely fit you well. You may also wish to measure the width of your nose to ensure that the bridge size is appropriate. Furthermore, Framesdirect.com often provides sizing guides that can help identify which frame sizes may best suit your face shape. It is worthwhile to take a moment to browse their website for additional tips and resources regarding frame sizing.
