Step-by-Step Glasses Size Guide

In this section, we will show you how to perform glasses measurements. But the first thing is to know what face shape you have. If you do not know, click here to have a check.

Then you need to know where to find the size measurement of your glasses. In general, you will find numbers that look like this 51-17-145 at the temples of your eyeglasses. Of course, these numbers come at different meanings.

The first number often refers to the lens width. Lens width is the horizontal diameter of the lens at its widest point. In optometry, another term is eye size.

The second number often means the bridge width. Bridge width is the part that joins the two lenses and sits over the nose. Some refer to this as the gap. The bridge width varies between 14 and 24 millimeters.

The third number often means the temple length. The temple is the arm that keeps the sunglasses on your face. That arm extends to the part that hangs on the ears. The length is usually 135, 140, or 145 millimeters.

Lens height measures the size of the lens vertically, that is from the top to the bottom of the lens. Although sizes may differ depending on the brand, the standard size is somewhere between 32 and 38 millimeters.

How to Perform Glasses Measurements?

If there is no number on the temple of eyeglasses, you can perform glasses measurements by yourself. Now, we will show how to do that.

To measure the glasses’ size, you need to prepare a ruler or a tape first. To measure the frame width, measure the entire horizontal front of the frame, from the furthest extended point on either side. As for lens height, you should measure the vertical height of the lens. As for the bridge, you should measure the part that goes across the bridge of your nose. The temple arms include the front of the frame on either side and the rest behind your ear. The lens width is the horizontal diameter of one lens. So, when measuring these, you should be careful.

After that, you have measured the glasses frame size. If you want to know whether your face is right for this frame, you can read the post: How to Measure Face for Glasses Frames - 7 Steps
