Understanding Frame Measurement
In eyewear, there’s three numbers that matter for measurements. Here’s a closer look at what they mean.
49/20-145
- The first number in the sequence (49) refers to the width of the lens in millimeters.
- The second number in the sequence (20) refers to the width of the bridge in millimeters.
- The third number in the sequence (145) refers to the length of the temple in millimeters.
Shop By Frame Width
Measured across the front of the frame from outer temple to outer temple, frame width helps take the guesswork out of finding your best fit.
Narrow: <141mm • Medium: 141–144mm • Wide: 144–147mm • Extra Wide: >147mm
Narrow Fit
This size is designed for individuals with smaller, more slender facial structures or delicate features. It is ideal if you have a narrow forehead and a softer or more pointed jawline, as standard glasses often slide down your nose or look too large.
This option is also great for anyone who prefers a minimalist look with smaller lenses that reveal most of your eyebrows.
Size: >141mm
Medium Fit
This is the standard size that comfortably fits the vast majority of people and provides a balanced, effortless look. It is the best choice if your face is neither noticeably wide nor narrow, and you typically wear standard hats or baseball caps without adjusting them to the largest or smallest settings.
If you want an everyday pair of sunglasses that sits naturally in the center of your cheeks, this is your go-to size.
Size: 141mm-144mm
Wide Fit
This option is built for people with broader facial features, such as a strong, angular jawline or a wide forehead. It is perfect for anyone who finds that average sunglasses pinch the sides of their head or leave deep marks behind their ears.
You will also love this fit if you have an average-sized face but prefer a bold, oversized look that provides extra sun coverage across your cheekbones.
Size: 144mm-147mm
Extra-Wide Fit
This size provides maximum room and comfort for individuals with very robust or prominent facial structures who struggle to find hats or glasses that fit comfortably. If standard and wide frames consistently feel tight, bow outward at the sides, or sit too high on your face, this specialized fit is made for you.
It offers a relaxed, pressure-free feel all day long while ensuring the sunglasses look proportional to your face.
Size: <147mm
Understanding Lens Categories
Understanding Lens Categories
Visible Light Transmission (VLT) measures how much visible light passes through the lens. Higher percentages indicate lighter tints, while lower percentages indicate darker lenses designed for brighter conditions.
*All RAEN lenses provide 100% UVA/UVB protection regardless of VLT category.
0 = very light tint/lowest light conditions
1 = light tint/low light conditions
2 = medium tint
3 = dark tint / bright conditions
4 = very dark tint/very bright conditions
Face/Lens Shape FAQs
How do I know what size sunglasses will fit me best?
Start with frame width. At RAEN, every style is categorized as Narrow, Medium, Wide, or Extra Wide based on the overall width of the frame, helping you find the fit that's right for you.
Not sure where you fit? Try the credit card test. Hold a standard credit card vertically against the center of your nose and look straight into a mirror:
• Narrow Fit: The edge of the card extends past the outer corner of your eye.
• Medium Fit: The edge of the card aligns with the outer corner of your eye.
• Wide / Extra Wide Fit: The edge of the card falls short of the outer corner of your eye.
You can also use our Find Your Fit tool for personalized recommendations based on your face shape and style preferences.
How do I figure out my face shape?
Face shape is all about proportions. Look straight into a mirror and focus on the outline of your face:
- Balanced and softly curved — most frame shapes work well.
- Full cheeks, softer jawline — try angular or square frames.
- Strong jawline, broad forehead — go with round or oval frames.
- Wider forehead, narrow chin — try frames with a wider bottom or rounded edges.
- Longer face length — larger or oversized frames add width and balance.
What’s the difference between lens width, bridge width, and temple length?
hese numbers describe how your sunglasses are built:
- Lens Width is the width of each lens (typically 47–54mm).
- Bridge Width is the distance between the lenses — it affects how the frame fits across your nose.
- Temple Length is the length of the arms (usually 140–150mm), which affects how the frames wrap around your ears.
Together, these measurements determine overall comfort and proportion.
