How do I measure my frames?

First look on the inside of the temple

On most frames, the three most important measurements are printed on the inside of the temple (the arm of the glasses), for example like this:

52 □ 18 – 145

• 52 = lens width
• 18 = bridge, that is the bridge width
• 145 = temple length

If you find these numbers, you don't need to measure them yourself.

Measure the total frame width

The total width is usually not marked on the temple, so measure it yourself. Measure the front of the frames with a ruler in a straight line from outer edge to outer edge. On the example frames, the total width is 140 mm.

If the measurements aren't on the temple, measure them yourself

This is how you measure the lens width, the bridge and the temple length:

Bridge (bridge width)

Measure the distance between the inner edges of the lenses at the nose. Measure from lens to lens, not from the edge of the frame. On the example frames, the bridge is 18 mm.

Lens width

Measure the lens at its widest point, horizontally. The frame is not included, only the lens itself. On the example frames, the lens width is 52 mm.

Temple length

Measure the temple from the hinge to the tip, including the curved end. The front of the frame is not part of the temple length. On the example frames, the temple length is 145 mm in total.

Tip: the curved end is easiest to measure with a tape measure. You can also lay a piece of string along the temple and then measure the length of the string with a ruler.

Compare with the measurements on the product page

Once you have your own measurements, compare them with the measurements shown on the product page of the frames.

You can also use the measurements to filter for frames that fit you: in the glasses collection you can narrow down the frames by, for example, frame width, lens width, bridge width and temple length.
