Frame Measurements


Finding a frame that fits is super important when buying glasses online. But did you know it's also super simple? We created our Frame Measurement Guide to make finding your fit even easier. Come discover what you need to know to measure your frames.

Reading Your Frame Size

To ensure your frames fit perfectly, you first have to determine which size frames are best for you. The best place to start is with the measurements on a pair you already own. You know those little numbers on the inside of its temple? That's what you're looking for. The frame measurements appear in the following order: lens width, bridge width, and temple length.

A few helpful tips for measuring your frame

Frame Width

A frame that is too narrow will make your face look wider, while a frame that is too wide will make your face look narrower. Typically, this is the most important factor in finding a pair of glasses that fits well.

To find frame width, measure the front of the frame from screw to screw.

Lens Width

Temple Length

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, with 135mm, 140mm, 145mm, and 150mm being the most common options.

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

Lens Width

Lens Height and Width

Lens Height and Width

Lens height is the distance from the top of a lens to the bottom. Lens Width is the distance from the left side of a lens to the right side.

To find lens height and width, measure the widest or longest parts of the lens.

Lens Width

Bridge Width

Bridge Width

The distance between two lenses equals a frame's bridge width. 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.

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