The measurements of most frames are written on the inside of the temple or branch. You'll see the measurements listed as 3 numbers:

• The first number refers to the width of the lens.
• The second to the width of the bridge (the middle part).
• The third to the length of the temple or branch.

Please note that while measurements can help you shop for frames of approximately the same size, similar measurements do not necessarily equal the same fit. If you are choosing frames based on their measurements, it is recommended that you also select a similar shape. For example, round frames are often smaller than other shapes. Hence, a round frame that measures 45-19-135 will likely offer a similar fit as a rectangle frame that measures 50-17-135.
