The Ultimate Size Guide for Sunglasses

How to Know if Sunglasses Don't Fit Right

Sunglasses are a statement piece that also offer critical sun protection, but finding a pair that isn’t too loose or too tight can be challenging. Maybe you find yourself constantly pushing your sunglasses up, or perhaps after wearing them for more than an hour, they leave noticeable red pressure marks.

There’s a better way—stop playing the sunglasses guessing game and find the right fit for your face with our comprehensive guide.

Top 3 Tips for Finding The Right Fit

1. Use an Old Pair as a Guide

Most people have that favorite pair tucked in the top drawer, but over time, the lenses may become scratched and the frame warped. Don’t throw those shades away! Instead, grab a ruler and measure the following in millimeters:

• Frame width: The width from hinge to hinge.
• Lens width: The lens from one horizontal edge to the other.
• Bridge size: The distance between the lenses inside the rim of the frame.

The right frame will have a width within 4 mm of what you measured for the frame width. These measurements will help you find the perfect pair, whether in-store or online.

2. Decide Your Preferred Fit (Oversized Looks vs. Regular)

When choosing a frame, decide if you want an oversized look or a regular fit. Oversized sunglasses typically look better on people with heart-shaped, round, square, or oval faces.

However, they’re not the right choice for everyone. Opt for a regular fit if you prefer more classic shapes. If you have a diamond, rectangular, or wide face, regular-fit sunglasses may be your best option.

3. Nose Bridge Fit 

Lastly, consider the nose bridge fit. Here are four of the most popular styles:

• Keyhole bridge: Shaped like an old-fashioned keyhole, with a wide top and narrow bottom.
• Saddle bridge: A curved piece of plastic that follows the entire width of the nose.
• Adjustable bridge: Often found on metal frames, these bridges feature adjustable nose pads.
• No nose pads: A nose bridge without pads, making it more durable but less adjustable.

Adjustable bridge frames with nose pads are ideal for those who prefer a custom fit, as they can be easily tailored to your preference. However, they’re not always the best choice for active wear. If you’re someone with an active lifestyle, opt for a saddle bridge with a non-slip interior or wrap-around arms for a more secure fit.

Style Recommendations by Fit

When choosing a style, consider your face width. While there are best practices for different face shapes, the actual width and fit of glasses can make a significant difference. We’ll discuss the best options for men and women, covering wide, medium, and narrow faces.

A helpful tool on the WMP Eyewear website is the option to search by face size. Simply click on “men” or “women,” then filter by frame size, selecting small, medium, or large.

Sunglasses for Wide Faces

Wide Fit Sunglasses for Men

Men with wide faces look great in oversized styles that complement their natural features. Think square or rectangle frames with bold browlines to add a refined look to every outfit. 

For wide-fit sunglasses for men, our go-to suggestion is Wesley in Crystal Brown. These lightweight acetate frames are a modern classic, with a no-nonsense browline and notched keyhole bridge. Take the pressure off your face and put it on this versatile style instead.

Wide Fit Sunglasses for Women

Women seeking a wide fit can enhance their natural features with sunglasses that balance curves and edges. We recommend aviators and cat-eye styles for those looking to stay on-trend, or square and rectangular options for a more classic look.

Our favorite wide-fit style for women is Gia in Beige Tortoise. These oversized, on-trend aviators feature a mixed-material construction that feels both vintage and modern. Adjustable nose pads and lightweight frame offer maximum comfort and style. 

Sunglasses for Medium Fit

Medium Fit Sunglasses for Men

Medium-fit sunglasses offer a balanced, versatile style. Choose lenses that aren’t too large but comfortably cover your eyes. Square and rectangular styles typically look best, but you can also try a round shape to make a statement.

Our most popular model for men seeking a medium fit is Francis in Crystal Stone Blue. These shades blend retro and modern elements with a square geometric design, keyhole nose bridge, and sleek angles.

Medium Fit Sunglasses for Women

Women seeking medium-fit sunglasses can try styles like aviators or those with rectangular lenses. Round sunglasses are also a great option, offering a fun look that transcends decades.

Our top medium-fit style for women is Emerson in Black Beige Tortoise. These square aviators bring a modern twist to a classic design. With a sleek, dual-color acetate frame, keyhole nose bridge, and bold browline, these shades are truly iconic.

Sunglasses for Narrow Faces

Narrow Fit Sunglasses for Men

For narrow faces, it's best to choose smaller sunglasses. Opt for round, oval, or smaller square styles. Be sure to measure your frame size before ordering to avoid selecting a pair that's too wide.

For men with narrow faces, we recommend Easton in Emerald Green. These round shades make a statement with their bold double bridge, sharp lines, and fresh color combination.

Narrow Fit Sunglasses for Women

For women with narrow faces, round and oval sunglasses offer an elevated style. Look for unique bridge designs and mixed-material frames to draw attention.

We recommend the Tate in Crystal Brown—a pair of round sunglasses that takes inspiration from retro styles with modern features like a lightweight acetate frame and polarized lenses. 

Stop settling for ill-fitting styles and find the perfect pair for your face. Measure your size, explore different fits, and consider key features like UV protection and nose bridges for optimal comfort and protection—all without compromising style.

Sometimes, the best way to find your perfect fit is through trial and error. Shop WMP Eyewear for affordable, designer-quality styles that stay relevant season after season. We offer free returns with store credit within 30 days, so you can try a few pairs until you find your next favorite.

Frequently Asked Questions

How Do I Measure My Face for Sunglasses?

To measure your face for sunglasses, grab a ruler and measure in millimeters. Start by measuring the width of your face from temple to temple (this is the frame width). Next, measure the bridge of your nose (bridge width) and the width of your eyes (lens width). These measurements are typically listed in the product description or on the inside of your sunglasses.

What Do the Numbers on the Inside of My Sunglasses Mean?

The numbers on the inside of your sunglasses indicate the frame size. From left to right, the numbers usually represent the model code, lens width, bridge width, and temple length. These numbers help you understand how the sunglasses will fit your face, so you can choose the right pair. 

What Are the Best Sunglasses for a Square Face?

The best sunglasses for a square face shape are round or oval frames. These styles soften angular features and provide a pleasing contrast.
