What Does Size E and W Mean in Sunglasses? Discover the Depth Details [2023]

Have you ever wandered through the aisles of your local sunglass shop only to be puzzled by those perplexing E and W sizes imprinted on the frames? DO you know “What Does Size E and W Mean in Sunglasses?”

I know I certainly have! For the longest time, I had no clue how the simple letters related to finding my most comfortable pair. But I’ve since discovered the key difference between E and W-sized frames that can make all the difference in your shades experience.

What Does Size E and W Mean in Sunglasses?

When shopping for sunglasses, you may notice frame sizes marked as E or W. These letters actually refer to the bridge and nose pad design to fit either Eastern or Western facial structures.

E Frames are Designed for Eastern Nose Bridges

The E in sunglass sizing stands for Eastern fit frames. These are designed for flatter nose bridges more common among Eastern Asian ethnicities.

Key features of E frames

• Narrower bridge width to fit flatter nasal profiles
• Lower nose pads placed closer together
• Lenses may be set closer together to align with narrower nose shape
• SLE (Second Locking Eyewire) helps keep E frames securely in place

So E sizing indicates the entire frame is engineered specifically to fit flattened Eastern nose bridges.

W Frames Suit Higher Western Nose Bridges

The W in sizes denotes Western fit frames suited to the higher nose bridges frequently found among Caucasian face shapes.

Characteristics of W frames

• Wider bridge dimensions to fit wider Western noses
• Higher nose pads spread farther apart
• Lenses set slightly farther apart to fit broader nasal shape
• Sturdy construction supports the weight of larger frames on higher bridges

Thus, W sizing reflects frames designed for elevated Western nose profiles.

Choosing Between E and W Frames

Should you choose E or W sunglass sizes Consider the shape and height of your nasal bridge

• If your bridge is low and flat, E frames designed for Eastern noses will likely fit better.
• If your bridge is higher and more prominent, W frames made for Western noses are a better match.
• Adjustable silicone nose pads allow customizing the fit for comfort.
• Try on different E and W sizes and styles to see which fits your facial contours best.

While E and W indicate general Eastern vs. Western fits, every face is unique. Let your individual nasal shape determine whether E or W sizes are right for you.

Other Measurements for Fit

Sunglass sizes may also include dimensions for lens width, bridge width, and temple length.

• Lens width in mm should align with the width of your face at the cheeks.
• Bridge width impacts how the frames sit on your nose.
• Temple length of 120mm-150mm ensures the arms extend properly behind your ears.

Combine evaluating the E vs. W fit with other sizing measurements for ideal shades.
