How to Measure Glasses Size

To find the best fit for your glasses, first you should look for the perfect frame width. Compare the 'FRAME WIDTH' options below with the width of your current glasses.

NOTE: Our company determines eyeglass sizes primarily by measuring the Frame Width, which is the distance between the two temples near the hinge screws (excluding the width of the temples). Our sizing categories are as follows:

Oversized: Frame Width > 146mm	Large: Frame Width 136–145mm
Medium: Frame Width 126–135mm	Small: Frame Width 110–125mm

1. Measure the Frame width of Glasses

Measure your glasses' frame width by taking the distance from the inside edge of one temple to the other, right by the hinge for accuracy. Then match this measurement with our FRAME WIDTH options to find the perfect fit. (Please note, frame width isn't usually marked on glasses; it needs to be measured manually.)

2. Other Useful Measurements

If you have glasses, look inside the temple arm or demo lens for numbers like 48-22-145. This indicates the lens width is 48mm, bridge width is 22mm, and temple length is 145mm. Compare your bridge width with our glasses. A good bridge fit ensures the glasses sit comfortably on your nose. Please note, many glasses (except acetate ones) have adjustable nose pads with a usual adjustment range of 3-5mm.
