Abbeglasses offers 4 different frame sizes (XS, S, M, L) so choosing the right one is key to making sure your new glasses correctly fit your face. Each size group is based on frame width.
Your perfect frame should be slightly wider than your face — no more than a fingertip's width between the temple and your face. Any wider is a sign that your frames are too wide.
Temple length is the measurement (in millimeters) of the frame's arms. The temple should fit horizontally and evenly along your face and fit comfortably along the outside of your ear.
Your eyes should be centered within your lenses. Eyeglass frames that are too wide will make your eyes appear too close, while frames that are too narrow will make your eyes look farther apart.
The distance between a frame's two lenses is called the bridge width. The bridge of your glasses should sit comfortably against your nose. If you have close-set eyes, the ideal bridge width is a lower number. If you have wide-set eyes, the ideal bridge width is a higher number.
The width includes lens and bridge widths in millimeters. Look on the inside of the temple arm to find your frame measurements.
Most eyewear brands print these details in a similar spot; if you already have a pair that you like, you can compare measurements to see how a certain frame of ours will fit you.
