How to Measure Sunglasses Size?

There’s something truly satisfying about finding that perfect pair of sunglasses – the ones that not only protect your eyes from the sun but also make you feel confident and stylish. But achieving that ideal blend of function, comfort, and fashion often comes down to one essential factor, getting the sunglasses size just right.

Fortunately, with a few simple techniques and a little know-how, you can easily determine the perfect measurements for your face, ensuring your sunglasses fit like a dream and look fantastic.

Below, we’ll show you how to understand sizing details and different methods for measuring them.

How to Read Sunglass Measurements

Have you ever noticed those tiny numbers printed on the inside of your sunglasses’ temples and wondered what they meant? Well, those numbers are actually like a secret code that tells you all about your sunglasses’ size and fit.

Usually, you’ll find three numbers, something like “52-18-140”. Each number tells you something important about your sunglasses size. The first number represents the lens width, which is like measuring how wide each “eye” of your sunglasses is. Consider drawing a line straight across the widest part of one lens – that’s the lens width in millimeters.

The second number is the bridge width, the distance between the two lenses right where they sit on your nose. A smaller number means the lenses are closer together, while a larger number means they’re farther apart. 

Finally, the third number measures the temple length, which is the length of those “arms” of your sunglasses that go over your ears. It tells you how long they are from the front of the frame to the very end.

Knowing These Numbers Matters

Knowing these numbers can be super helpful when you’re trying to find your next perfect pair and major money and time-saver for your sunglass-buying journey. 

The bridge width is the most important number to pay attention to because it affects how well your sunglasses sit on your nose. If the bridge is too narrow, your sunglasses might pinch or feel uncomfortable. If it’s too wide, they might slide down your nose or feel loose.

You have a bit more flexibility with the lens width and temple length. As long as these measurements are close, your sunglasses should fit comfortably. But getting the bridge width right is crucial for keeping your sunglasses in place and feeling comfortable all day long.

Quick Tricks for Sunglass Sizing

Let’s start with the basics: your face! Knowing your face size is like having a secret weapon for picking sunglasses that make you look good and feel comfortable. You wouldn’t buy a pair of shoes without knowing your shoe size, right? The same goes for sunglasses. Knowing your face size helps you avoid those “too big” or “too small” situations and ensures your sunglasses complement your unique look.

We’re keeping it easy, no complex tools are required. Grab a ruler or a trusty credit card, and let’s get started. 

With a ruler in hand, simply position it horizontally below eye level and align the ends with the widest points of your face (usually around your temples). The measurement you get in millimeters will give you a good starting point for choosing sunglasses that fit comfortably.

No ruler? No problem! You can use a standard credit card to get a general idea of your face size. Hold the card vertically against the bridge of your nose, aligning one edge with the center of your eye. If the other edge of the card extends past the outer corner of your eye, you likely have a larger face size. If it lines up almost perfectly with the outer corner, you’re probably in the medium range. And if it falls well short of the outer corner, you likely have a smaller face size.

Using Your Current Pair as a Reference

Another helpful trick is to look at a pair of sunglasses that you already own and love the fit of. If the size numbers are still visible on the inside of the temples, you can use those as a reference point when shopping for new sunglasses. However, keep in mind that different brands might have slight variations in their sizing.
