Measure your glasses
When buying glasses online, you want to make sure you find frames that will fit you just right. Luckily, it’s really easy to find your perfect frame measurements.
Find your frame dimensions
Grab a pair of glasses that fits you just right to find your perfect measurements.
Your glasses might have numbers on the inside of the temple arm. These refer to the lens width, bridge width, and temple arm length.
The most important measurement, frame width, will not be printed on the temple arm. You can measure it yourself using the guide below.
Your pupillary distance (PD)
If you don’t know your PD, you can use our digital PD tool.
Measure horizontally across the frame from hinge to hinge.
Measure the lens vertically at its tallest point. If you have bifocals or progressives, this should be at least 30 mm.
Measure the distance from lens to lens at the closest point. For the bridge, stick to a range of 2 mm less or more than the measurement.
Measure from the hinge to the bend, and then from the bend to the end of the arm. Add the two measurements together for the total temple arm length.
Measure the lens horizontally at its widest point.
Your frames will fit great if you stay within a range of 2-3 mm less or more from the total measurement.
