How To Measure Sunglasses Size?

Finding the perfect pair of sunglasses isn’t just about style—it’s about fit! Wearing the wrong size can lead to discomfort, poor sun protection, and a less-than-flattering look. Whether you have a petite face, an average width, or a bold, wide structure, understanding sunglasses sizing is the key to rocking your shades with confidence.

So, how do you measure sunglasses size the right way? Let Andre Montana break it down for you.

Do Sunglasses Have Sizes?

Yes, they do! Just like shoes and clothing, sunglasses come in different sizes to fit various face shapes and structures. When shopping for sunglasses, you’ll often see numbers like 52-18-140 printed on the inside of the arm. These represent:

• Lens width (or frame width)
• Bridge width (distance between the lenses)
• Temple length (arm length from hinge to ear)

Choosing the right size ensures maximum comfort, a balanced look, and better UV protection.

Sunglasses Size Categories

Sunglasses generally fall into three size categories based on frame and lens width:

1. Small Sunglasses

Perfect for those with narrow faces or anyone who prefers a sleek, understated look. Small frames help avoid an oversized or “bug-eyed” appearance.

2. Medium Sunglasses

A universal size that fits most face shapes. If you’re unsure what size works best, medium is a safe bet.

3. Large Sunglasses

Ideal for wider face shapes or those who love bold, oversized styles like aviators and wayfarers. They provide more coverage and make a strong fashion statement.

How to Measure Your Face for Sunglasses?

Before you buy new shades, measuring your face size ensures a snug and comfortable fit. Here’s how:

Find Your Lens Width or (Frame Width) Measurement

Here’s how to measure it accurately:

• Measure horizontally across your current sunglasses or eyeglasses.
• If you don’t have a pair to measure, use a ruler to estimate the width of each eye socket.
• Most frames fall between 46mm - 58mm per lens.

Find Your Bridge Measurement

The bridge measurement refers to the width of the gap between your lenses, which determines how comfortably your glasses or sunglasses sit on your nose.

• The bridge width is the gap between your lenses.
• A narrow bridge (14-18mm) suits smaller noses, while a wider bridge (18-22mm) fits broader noses.
• Sunglasses that don’t sit comfortably on your nose might have the wrong bridge size!

Find Your Temple Length

The temple length refers to the arms of your sunglasses or eyeglasses that extend from the frame to rest over your ears. This measurement is crucial for ensuring a comfortable and secure fit.

• The temple length is the arm of the sunglasses that sits over your ear.
• Standard lengths range between 120mm - 150mm.
• If your sunglasses feel tight behind your ears, you might need a longer temple length.

3 Types of Sunglass Measurements

When choosing sunglasses, you’ll typically see three key measurements printed on the frame:

Eye size (or frame size)

The eye size, also known as the frame size, refers to the width of a single lens measured in millimeters. This measurement plays a key role in determining the overall fit and appearance of your sunglasses or eyeglasses.

• Refers to the width of one lens, typically 46mm - 58mm.
• Determines how large the sunglasses will appear on your face.

Bridge size

The bridge size refers to the distance between the two lenses of your sunglasses or eyeglasses. This measurement is essential for ensuring a secure and comfortable fit on your nose.

• This is the distance between the two lenses.
• A correct bridge size prevents sunglasses from sliding down your nose.

Temple size

The temple size refers to the length of the arms (temples) of your sunglasses or eyeglasses, extending from the frame to rest over your ears. This measurement is crucial for achieving a secure and comfortable fit.

• The length of the arms (temples) extending to your ears.
• Ensures a secure and comfortable fit without pressure points.

Is There an Average Sunglasses Size?

There’s no one-size-fits-all when it comes to sunglasses, but most frames fall into these standard measurements:

• Small Faces: 46mm-49mm lens width
• Medium Faces: 50mm-55mm lens width
• Large Faces: 56mm+ lens width

However, face shape and style preferences play a huge role—so don’t be afraid to experiment with different fits!

Why Is Choosing the Correct Sunglasses Size Important?

The right sunglasses size doesn’t just affect how you look—it affects comfort, durability, and eye protection.

• Prevents slipping – A proper fit ensures your sunglasses don’t slide down your nose.
• Enhances UV protection – Well-fitted frames block sunlight from the sides and reduce glare.
• Avoids headaches – Tight sunglasses can cause pressure points behind the ears and nose.
• Improves style – Frames that complement your face shape and size give you a balanced, polished look.

Getting the right size means you not only look great but feel great, too!

Find Your Perfect Sunglasses Fit

Choosing the right sunglasses size is just as important as choosing the right style. Whether you prefer classic aviators, oversized wayfarers, or sleek rectangular frames, getting the perfect fit ensures comfort, UV protection, and effortless style.
