Sunglasses are the ultimate accessory: They protect your eyes from harsh light and they make you look cool. The question is, what kind of cool are you going for?
Much like traditional glasses frames, sunglasses come in an array of styles. Sometimes a slight tweak in a frame’s design—like a rounded corner or a keyhole bridge—can make a big difference in the impression it leaves.
Read on to learn more about the different types of sunglasses, their signature shapes, and how they can augment your fashion choices.
Choosing the right pair of sunglasses isn’t just about blocking sunlight. It’s about framing your personality, sharpening your look, and turning a simple outfit into a statement. At OPIUM Eyewear, we believe sunglasses are a signature of style.
If you’ve ever wondered which sunglasses suit your face, you’re not alone. Understanding sunglass styling according to the face shape is the key to upgrading your look instantly. This guide will help you master how to choose sunglasses for your face shape and find the perfect match.
At A Glance: Face Shape and Frame Guide



Before choosing a pair of sunglasses, it helps to know your face shape. Use this quick chart to match your features with the frame styles that bring out your best look.
Round Face Shape
Round faces have soft curves and fuller cheeks, which can make the overall shape appear shorter and wider. Frames with structure help add definition, sharpen the outline of the face, and create a more lifted look. Choosing angular styles can make the cheeks appear slimmer and the face look more elongated.
Best Sunglasses for Round Face Shapes:
Frames to Avoid if You Have a Round Face Shape:
• Round
• Oval
• Oversized styles with circular lenses
Oval Face Shape
Oval faces are naturally balanced with gentle curves and well-proportioned features. This gives you flexibility when choosing sunglasses, but it is still helpful to pick frames that maintain this harmony. Styles with clean lines or a bit of structure tend to complement the shape without overwhelming it. Slightly larger frames can also work well as long as the size matches the width of your face.
Best Sunglasses for Oval Face Shapes:
Frames to Avoid if You Have an Oval Face Shape:
• Very narrow frames
• Extremely oversized designs
• Small round frames
Square Face Shape
Square faces have a strong jawline, a broad forehead, and straight sides. Curved frames help soften the angles and create a more relaxed look. Sunglasses with rounded edges can reduce the appearance of sharp lines and bring balance to the lower half of the face. Choosing styles that introduce gentle curves can create a smoother overall appearance.
Best Sunglasses for Square Face Shape
Frames to Avoid if You Have a Square Face Shape:
• Square
• Rectangle
• Sharp geometric styles
Heart-Shaped Face
Heart-shaped faces are widest at the forehead and taper toward a narrower chin. This creates a naturally striking silhouette, and the goal is to find frames that balance the width at the top with the slimmer lower half. Frames with softer edges or upward angles can help direct attention toward the center of the face rather than the forehead.
Best Sunglasses for Heart-Shaped Faces:
Frames to Avoid if You Have a Heart-Shaped Face:
• Thick top-heavy frames
• Square shapes
• Rectangle frames with sharp upper corners
Diamond Face Shape
Diamond faces have pronounced cheekbones with a narrow forehead and chin. This face shape looks great with frames that soften the cheek area and highlight the eyes. Styles that open up the space around the eyes or add a gentle lift to the outer corners can bring balance to the angular structure.
Best Sunglasses for Diamond Face Shapes:
Frames to Avoid if You Have a Diamond Face Shape:
• Narrow rectangle frames
• Square frames
• Thick angular geometric shapes
Oblong Face Shape
Oblong faces are longer than they are wide, often with a straight cheek line. Frames that add width or height can help shorten the overall look of the face and bring more balance. Larger or deeper styles can help shift attention toward the center of the face instead of its length.
Best Sunglasses for Oblong Face Shapes:
Frames to Avoid if You Have an Oblong Face Shape:
• Small frames
• Narrow rectangle frames
• Rimless styles

How to Determine Your Face Shape

Before shopping for sunglasses, you need to know your face shape. Here’s a simple method:
Step 1: Pull your hair back and stand in front of a mirror.
Step 2: Using a dry-erase marker or lipstick, trace the outline of your face on the mirror.
Step 3: Step back and examine the shape.
Alternatively, measure these four areas:
- Forehead width (widest part)
- Cheekbone width (from the outer corner of one eye to the other)
- Jawline width (widest part of jaw)
- Face length (from hairline to chin)
Now let’s identify which category you fall into and find your perfect sunglasses.
