1. Introduction to Measuring Sunglasses Size

When it comes to sunglasses, a proper fit is more than just a matter of aesthetics; it’s about comfort and function. The wrong size can lead to headaches, discomfort, and even damage to your eyewear. But here’s the kicker… finding the right size isn’t as simple as just guessing. In this article, we’ll show you exactly how to measure your sunglasses size, using the three key measurements: lens width, bridge width, and temple length. This information will not only enhance your buying experience but ensure that you never have to deal with ill-fitting sunglasses again.

The sunglasses industry has seen a shift toward custom-fit products, which is why understanding these measurements is crucial in both retail and wholesale contexts. By the end of this guide, you’ll have a thorough understanding of how to find the perfect pair of sunglasses that fits well and looks great.

2. Understanding Sunglasses Size Terminology

When you shop for sunglasses, you may encounter terms like “lens width,” “bridge width,” and “temple length.” What’s the real story? These are the fundamental measurements that determine whether your sunglasses will sit comfortably on your face. Let’s break down each term to ensure you know exactly what to look for.

Lens Width: This is the horizontal width of one lens. It’s the most important measurement when considering the overall size of the sunglasses. The average lens width ranges from 40mm to 60mm. A pair of lenses that are too wide may slide down your nose, while ones that are too narrow might feel too tight.

Bridge Width: This refers to the distance between the lenses, measured at the bridge of the nose. The bridge width typically ranges from 14mm to 24mm. Ready for the good part? This measurement is essential for comfort, as it affects how the sunglasses sit on your nose.

Temple Length: This is the length of the arms (or temples) of the sunglasses, from the hinge to the end tip. Most temples range from 120mm to 150mm. Here’s the deal… temple length affects how the sunglasses stay in place on your ears. If the temples are too short, the sunglasses may feel loose; if they’re too long, they may pinch behind your ears.

3. Tools You Need to Measure Sunglasses Size

Measuring sunglasses size is a simple process, but you’ll need the right tools. This is where it gets interesting… The basic tools required for sunglasses measurement are likely already in your home or office. To get the most accurate measurements, you’ll need either a measuring tape or a ruler.

A measuring tape is especially useful for measuring the bridge width and temple length, as it can easily conform to the shape of the frame. A ruler is effective for measuring the lens width, particularly if the sunglasses are flat or have a distinct shape.

Optional Tools: For precise measurements, especially if you’re creating custom sunglasses for clients, you may use calipers. This tool allows you to measure dimensions with greater accuracy and is ideal for professional eyewear manufacturers.

Let’s look at the tools you need and where to find them:

RulerLens width measurementAvailable at office supplies
CalipersHigh-precision measurementsAvailable online or at hardware stores

4. How to Measure the Lens Width

Now that you have your tools, it’s time to measure the lens width. But here’s the kicker… You might think this step is obvious, but it requires precision to get it right. To measure the lens width, you need to measure the horizontal length of one lens at its widest point.

Place your ruler or measuring tape across the front of the lens from one side to the other. What’s the real story? Ensure the tape is parallel to the frame to get an accurate measurement. The standard lens width is typically between 50mm and 60mm, but this will vary depending on the style of the frame.

Common mistakes to avoid:

  • Don’t measure at an angle. This can give inaccurate results.
  • Make sure you measure across the lens only, not the entire frame.
  • This is where it gets interesting… You can measure a pair of sunglasses that you already own to compare the lens width and ensure you get a similar fit with your next pair.

5. How to Measure the Bridge Width

Measuring the bridge width is essential for comfort. The bridge is the part that sits on your nose, so getting the right measurement is key to preventing discomfort and slippage. To measure the bridge width, use a measuring tape or ruler and place it across the space between the two lenses.

You might be wondering how tight or loose the bridge should be. Ready for the good part? If the bridge width is too wide, your sunglasses will sit too low on your nose. If it’s too tight, they’ll press against your nose, causing discomfort. The average bridge width falls between 14mm and 24mm.

To help you visualize, here’s a quick table comparing various bridge widths:

Sunglasses BrandBridge Width (mm)Best Fit For
Brand A18Medium faces
Brand B20Wide faces
Brand C22Narrow faces

6. How to Measure the Temple Length

Finally, let’s move on to measuring the temple length. What’s the real story? The temples are the arms of your sunglasses that go behind your ears. If the temples are too short, your sunglasses will be uncomfortable, and they may fall off. If they’re too long, they might cause pinching or make the sunglasses feel unstable.

To measure the temple length, use a measuring tape or ruler and measure from the hinge to the end tip of the temple. Most sunglasses temples range from 120mm to 150mm. This is where it gets interesting… A well-fitting temple ensures that the sunglasses stay securely on your face without causing any discomfort.

Brand A135Average size
Brand B140Larger heads
Brand C145Small heads

7. Understanding the Sunglasses Frame Size

Frame size refers to the overall dimensions of the sunglasses, including lens width, bridge width, and temple length. What’s the real story? The frame size determines how well the sunglasses fit on your face and whether they look proportionate to your features.

To choose the right frame size, combine all three measurements. If you find a pair of sunglasses with a 56mm lens width, 18mm bridge width, and 140mm temple length, this would typically fall into the medium size range. Sunglasses with larger dimensions, such as 60mm lens width and 22mm bridge, would be considered large size.

Frame SizeLens Width (mm)Bridge Width (mm)Temple Length (mm)

Medium54-5618-20130-140
Large58-6020-22140-150

8. How Sunglasses Fit: Comfort vs. Fashion

When selecting sunglasses, it’s important to balance comfort with fashion. You might be wondering how much the fit really matters when choosing a stylish pair. The truth is, comfort should never be compromised for the sake of fashion.

Comfortable sunglasses fit snugly but don’t press too hard on your temples or nose. Here’s the deal… If you’re constantly adjusting your sunglasses or feeling discomfort, you’ll likely avoid wearing them altogether. On the other hand, fashionable sunglasses can elevate your look, but only if they fit well. So when selecting eyewear, always check the fit before considering how stylish they are.

9. How to Check if Sunglasses Fit Your Face Shape

Choosing sunglasses that complement your face shape is just as important as getting the measurements right. What’s the real story? Certain frames suit specific face shapes, and the right fit will enhance your overall appearance. For example, round sunglasses complement square faces, while angular frames are great for round faces.

To check if sunglasses fit your face shape, hold the sunglasses up to your face and see if they look proportional. Ready for the good part? If the sunglasses seem to overwhelm your features or look out of place, they may not be the right style for you.

RoundSquare, angular frames
OvalCat-eye, rectangular
SquareRound, aviator
HeartOval, butterfly

10. Adjusting Sunglasses for a Better Fit

If your sunglasses don’t fit perfectly, don’t panic! What’s the real story? You can adjust your sunglasses to make them more comfortable. Small adjustments can go a long way, especially when it comes to temple length, nose pads, or even the frame width.

To adjust the nose pads, gently push them inwards or outwards until they rest comfortably on your nose. But here’s the kicker… If the temples are too tight or loose, you can carefully bend them for a better fit. Always make small adjustments to avoid damaging the frame. If you’re unsure, take your sunglasses to an optician for a professional fit.

11. Measuring for Prescription Sunglasses

Prescription sunglasses require some extra attention when it comes to sizing. What’s the real story? In addition to the standard measurements, you also need to consider the thickness of the lenses and how they affect the fit. Prescription lenses may be thicker, requiring adjustments to ensure the sunglasses sit comfortably on your face.

It’s also important to check the lens curve and frame compatibility when selecting prescription sunglasses. Always consult with an optician to ensure that the sunglasses can accommodate the prescription lenses you require.

Prescription TypeLens Thickness (mm)Recommended Fit
Standard2-4Regular size
High Prescription5+Larger frames

12. Sunglasses Sizing for Kids and Teens

For children and teenagers, proper sizing is even more critical. What’s the real story? Kids’ faces are smaller, so sunglasses need to fit snugly without sliding off. Kids’ sunglasses often come with adjustable features to accommodate growing faces.

When choosing sunglasses for kids, measure their face size first. But here’s the kicker… If you’re unsure of your child’s size, choose a pair with adjustable temples and a flexible frame for a custom fit.

Age GroupLens Width (mm)Bridge Width (mm)Temple Length (mm)
Kids (4-7)45-5014-16110-120
Teens (8-12)50-5416-18120-130

13. Common Mistakes When Measuring Sunglasses Size

Measuring sunglasses is straightforward, but there are common mistakes that can lead to inaccurate results. Here’s the deal… People often measure too quickly or overlook important details, such as the frame material or the curvature of the lens. These mistakes can lead to discomfort and poor fitting sunglasses.

To avoid these mistakes, always take the time to measure carefully. Ready for the good part? If you have a pair of sunglasses that fits well, use them as a reference for future purchases.

MistakeDescriptionHow to Avoid
