Understanding Face Shapes

Different face shapes require different styles of sunglasses to achieve a harmonious balance. Whether you have a round, square, oval, heart-shaped, or any other face shape, familiarize yourself with the characteristics of your face shape to better understand which sunglass styles will suit you best.

Measuring the Sunglasses

To determine your sunglasses size accurately, you'll need a measuring tape and a mirror. Follow these steps:

1. Temple Width: Measure the distance between the temples, where the sunglasses' arms rest.
2. Frame Width: Measure the total width of the frame from one end to the other.
Lens Width: Measure the width of the lens from the widest point.
3. Bridge Width: Measure the distance between the lenses, where they rest on the bridge of your nose.
4. Arm Length: Measure the length of the arms from the frame to the curve that fits behind your ears.

Consideration of Frame Styles

Explore the various frame styles available, such as aviator, wayfarer, cat-eye, round, and more. Consider your face shape and its characteristics when selecting a frame style. Pay attention to factors like proportion, size, and design to ensure a complementary and visually appealing look.

Determining Lens Size

The size of the lenses plays a significant role in the overall fit and style of sunglasses. Aim for a balanced proportion between the frame and lens size. Consider how the lens size interacts with your face shape, and ensure they provide adequate coverage and protection for your eyes.

Trying on Sunglasses

Try on sunglasses either by visiting a physical store or using virtual try-on tools available online. Focus on the fit and comfort of the sunglasses, ensuring they don't pinch or cause discomfort. Assess the fit from different angles—front, side, and top—to ensure they suit your face shape and provide an appealing aesthetic.

Additional Factors to Consider

Take into account your face width and how it corresponds to the proportions of the sunglasses. Consider your personal style preferences to find sunglasses that align with your fashion sense. If you require prescription sunglasses or have any special requirements, consult with an optician to find the right size and style for your needs.


Properly sizing sunglasses is crucial for comfort, eye protection, and enhancing your overall appearance. By understanding your face shape, measuring accurately, considering frame styles and lens size, and trying on sunglasses, you'll be well on your way to finding the perfect fit. Follow the steps outlined in this guide, and enjoy the benefits of well-sized sunglasses that not only shield your eyes but also elevate your style.
