Buying eyeglasses online may be challenging for some but we’ve got you covered! All you need to get started is the measurements of your current eyeglasses.
Locate the three numbers found on the inside arm of your eyeglasses. You can expect to see:
- Lens Width of 31-64 mm
- Bridge Width 9-24 mm
- Arm Length 115-155 mm
If the numbers aren’t printed on your glasses, never fear. You can measure your frame dimensions with a millimetre ruler or cloth measuring tape.
DIY: How To Measure Your Glasses
Measure horizontally inside the frame width. Put the edge of your ruler over your frame and measure from the left hinge to the right hinge.

Measure the temple/arm length. Place your ruler at the hinge and measure straight across to the furthest end of the temple.

Measure the bridge. The distance between the inside of one lens to the other — the part of the frame that sits just above (or on) your nose.
A bridge that’s too tight can pinch the nose and cause your frames to sit too high on your face, while a bridge that’s too wide keeps sliding down your face all day (talk about annoying!).
So, after all, you can order your glasses online with your own bridge measurement if you’ve concluded that…
- If your bridge is small:look for something in the 14-16 mm range.
- If your bridge is medium:you’ll be best suited to a bridge between 17-19 mm.
- If your bridge is large:your size would be 20-23 mm.
It is also important to look at the location of the bridge on the frame. If you have a high bridge, frames with a bridge closer to the brow line are great! If you have a low bridge, frames with a curvier brow or a lower bridge would be a better choice.
