How to Choose the Right Size of Sunglasses
The Art of Perfect Fit
The first thing to know is that sunglass sizes, much like clothing sizes, are not universal. The same size might fit two different people in entirely different ways due to differences in face shape, bridge width, and other factors. Here's the secret: the key numbers that determine sunglass size are the lens width, bridge width, and temple length. Most sunglasses come with these measurements printed on the arm of the frame, and knowing how to read these measurements can instantly give you an idea of the fit.
1. Lens Width:
This is the width of each lens measured in millimeters. Typically, lens width ranges from 50 mm to 60 mm. If you prefer oversized sunglasses, go for a larger lens width. For a more classic or smaller look, opt for something under 55 mm.
2. Bridge Width:
The bridge width refers to the distance between the two lenses, which sits on the nose. A smaller bridge width is ideal for narrow noses, while a wider bridge is suited for broader noses. Most bridge widths range between 14 mm and 24 mm.
3. Temple Length:
This is the length of the sunglasses’ arms, running from the hinge to the end that hooks behind your ear. Typically, the length is around 135 mm to 145 mm. Choose a temple length that keeps the sunglasses snug without too much pressure.
Face Shape Matters: Sunglasses Style Guide Based on Face Shape
Another critical aspect of choosing the right size of sunglasses is your face shape. Not every frame will look great on every face, and finding one that enhances your natural features is crucial. Here’s a breakdown of the most common face shapes and the styles of sunglasses that suit each.
1. Oval Face Shape
If you have an oval face, you're in luck! Almost all sunglasses will look good on you. Oval faces are characterized by balanced proportions and a slightly narrower forehead and jawline. To maintain this balance, choose sunglasses that are as wide as the broadest part of your face.
Recommended Sunglasses for Oval Faces: Aviators, wayfarers, and oversized sunglasses.
2. Round Face Shape
Round faces are characterized by soft curves and a lack of defined angles. The goal here is to add some structure and contrast to balance out your natural softness. Sunglasses with sharp, angular lines are perfect for achieving this.
Recommended Sunglasses for Round Faces: Square frames, rectangular frames, and wayfarers.
3. Square Face Shape
Square faces have strong jawlines, broad foreheads, and wide cheekbones. The key to choosing the right sunglasses for a square face is to soften the angles. Look for frames with rounded edges that contrast with your sharp facial features.
Recommended Sunglasses for Square Faces: Round frames, aviators, and oval sunglasses.
4. Heart Face Shape
A heart-shaped face typically has a broad forehead and a narrower chin. The idea is to balance the proportions by choosing sunglasses that are wider at the bottom than at the top.
Recommended Sunglasses for Heart-Shaped Faces: Aviators, round frames, and cat-eye sunglasses.
5. Diamond Face Shape
Diamond faces are rare and are characterized by narrow foreheads and jawlines with broad cheekbones. The best sunglasses for this face shape are those that accentuate the eyes while softening the cheekbones.
Recommended Sunglasses for Diamond Faces: Oval frames, cat-eye frames, and rimless styles.
Sunglasses Size Chart: Find Your Perfect Fit
Here’s a simple size chart to help you determine the right fit based on the size of your face:
| Face Size | Lens Width (mm) | Bridge Width (mm) | Temple Length (mm) |
|---|---|---|---|
| Small Face | 50 mm – 52 mm | 14 mm – 16 mm | 135 mm – 140 mm |
| Medium Face | 53 mm – 56 mm | 16 mm – 18 mm | 140 mm – 145 mm |
| Large Face | 57 mm – 60 mm | 18 mm – 20 mm | 145 mm – 150 mm |
This chart offers a general guide, but remember that comfort is key. Sunglasses should sit comfortably on your nose and not pinch behind your ears. If they leave marks after wearing them for a short time, consider adjusting the fit or trying a different size.
How to Measure Your Face for Sunglasses
If you’re unsure about your face size or shape, you can easily measure it at home. All you need is a mirror, a ruler or measuring tape, and a piece of paper. Here's a quick guide:
- Measure Your Face Width: Stand in front of a mirror and measure the distance from the left temple to the right temple. Record this measurement.
- Measure Your Face Height: Measure from the middle of your hairline to the bottom of your chin.
- Measure Your Nose Bridge: Measure the width of your nose bridge where your sunglasses would sit.
- Measure Your Jawline: Measure from the edge of your chin to the bottom of your ear.
Compare these measurements with the sunglasses' size chart above, and you'll have a good idea of what size sunglasses to look for.
Sunglasses Materials and Durability: Another Factor to Consider
When choosing the size of your sunglasses, also consider the material. The material can affect the weight, durability, and comfort. Here’s a breakdown of the most common materials used in sunglasses frames:
- Plastic (Acetate): Lightweight and affordable, plastic frames are a popular choice. However, they can be less durable than metal frames.
- Metal: Metal frames are typically stronger and more durable, but they can be heavier on the nose and ears.
- Titanium: Titanium is lightweight, durable, and hypoallergenic, making it a great choice for those with sensitive skin.
- Nylon: Nylon frames are lightweight and durable, often used in sports sunglasses for their flexibility.
Polarization and Lens Options
While the size and shape of your sunglasses are crucial, don't forget about the lenses themselves. Polarized lenses reduce glare and are a great option for outdoor activities, especially when you're around water, snow, or sand. You can also choose between tinted lenses, mirrored lenses, or photochromic lenses that adjust based on lighting conditions.
Why Size Matters for Eye Protection
Finally, never forget that sunglasses are primarily designed to protect your eyes from UV rays. Sunglasses that are too small may expose parts of your eyes to harmful sunlight. Ensure your sunglasses provide 100% UV protection, and consider larger lenses for better coverage.
Conclusion: Style Meets Function
Finding the perfect size of sunglasses is a balance of style, comfort, and protection. By understanding your face shape, measuring your facial dimensions, and knowing how to read sunglasses sizes, you can ensure that your next pair not only looks good but also feels great. Sunglasses are an investment in both fashion and eye health, so take the time to choose wisely.
Now, go out there and rock your perfectly-sized sunglasses with confidence!
