Have you ever noticed that when someone removes their eyeglasses, there is a mark on their nose and cheeks? Well, it seems normal, but sometimes it can lead to redness, pain and even skin allergies. But, you might be wondering why it happens- it is because your eyewear does not sit properly on your face.
If you look closely inside your temples, you will spot some digits, and that’s what tells you about your frame size. They are the measurements of the lens width, bridge width and temple length, respectively. These are the numbers that ensure a snug fit on your face and ensure comfort. To have a clear and comfortable vision, you need to check the sizing of your frame. Let’s understand in detail about ‘how to know your glasses frame size.’
How to Know Your Glasses’ Frame Size?

As mentioned earlier, the numbers mentioned on your pairs are important. We will tell you the purpose of each figure and how they are helpful in determining the frame size. Let’s start with an example. We have randomly selected one of our pairs and read the numbers written on the temple: 53-18-142. Now, let’s elaborate:
Lens width of your glasses
The first number is the lens width (53). It is the width of your lens that is denoted in millimetres (mm). Remember, this number doesn’t denote the surrounding frames, it’s just the measurement of the lenses.
The bridge width of your glasses
Both the lenses of your eyeglasses are connected by a bridge, the second number is the measurement of the bridge width (18). Bridges having larger widths are perfect for wider noses, and bridges with smaller widths are best for narrow noses.
Temple length of your glasses
The temple length is the measurement of your glasses’ temples (142). The perfect temple lengths will only add to the comfort instead of hurting your ears.

Measure Your Face to Find the Right Fit
Now, what if you are shopping online and want to find the perfect fit for your face? Don’t worry, it’s easy. Get a measuring ruler and I will tell you how it’s done:
Stand in front of a mirror and hold the ruler in line with your temple.
Measure the distance between your temples in inches.
Multiply your measured value by 25.4 to convert from inches to millimetres.
Now, calculate the total frame width of the glasses you want. This would be a sum of both the lenses' width plus the bridge width, and get a frame that’s closer to your face size.
