Glasses Frame Measurements

Finding the ideal eyeglass frame size is super important when you are buying glasses online. It’s very easy now. Because we’ve created some guides to make finding your personal fit an easy and quick process. Here are a few helpful tips for eyewear measurements.

Finding the Perfect Frame Width

The frame which is too narrow will make your face look wider, while the frame which is too wide will make your face look narrower. This is one of the most important factors when finding a pair of glasses that fits you well. Find a frame which is slightly wider than your face -- no more than a finger width between the temple and your face. Any wider is a sign that your frames are too wide.

Tips: This measurement is not printed on the temple of your glasses. If you want to find it, please take your measuring tape and measure horizontally across the front of your frames, including any hinges or design features that stick out on the sides.

Get Cozy with Your Temple Length

Temple length is the measurement in millimeters of the “arms” of the frame. This measurement does not vary as much as the others. 135mm, 140mm, 145mm, and 150mm are the most common options. The temple should fit horizontally and evenly along your face and fit comfortably along the outside of your ear.

Tips: To find temple length, measure one from screw to tip.

Picking the Right Lens Height and Width

To determine which lens size is right for you, you should know that a small lens width is 50mm or less, medium is between 51mm and 54mm and large is any lens wider than 55mm. You can choose your lens size according to your lens index and your face shape.

Selecting the Ideal Bridge Width

The distance between two lenses is equal to a frame's bridge width. The bridge should sit comfortably flush against your nose. If you have close-set eyes or want a narrow bridge, this number should be lower. If you have wide-set eyes or want a wide bridge, this number should be higher.

The location of your nose can help determine which frame style works best for you. If your nose is higher on your face, an eyeglass style whose bridge is even with the frame’s brow line will look best. If your nose is situated a bit lower on your face, a frame with a lower bridge and curved brow line will be better at your features.

Tips: To find bridge width, measure the distance between the inner edges of each lens.
