Match Sunglass Shape with Face Type


Sunglass shape is very important. Every face requires a different type of sunglass. If we wear the wrong shape, the face will look like a cartoon!

In general, an oval face can wear almost any type of sunglasses. A round face should avoid a big frame since it will make you more round. Square face should avoid a pointed shape. A heart-shaped face should choose sunglasses as the face.

But these are just general observations. To choose the right sunglass, you have to first determine your face type. And then match the design that complements your facial features.

It may be overwhelming to select the right frame to match the face type. But did you know that there is a perfect sunglass style for you? All you have to do is know your face shape.

The product designers have created the perfect sunglass fit for every face type. And that too in a variety of frame materials, lens type and color, and of course, your budget.

Let’s clearly understand the different face types and sunglass shapes and then correlate the ideal match for each.

Identify Your Face Shape


1. Oval Shape

This face shape has a broad forehead with prominent cheekbones and slopes down beautifully towards the chin.

Celebrities with Oval-shaped faces: Blake Lively, Salma Hayek, and Julianne Moore.

Oval face shapes are adaptable to almost any style of sunglasses, whether it's Aviator sunglasses or a wider frame, angled glasses, or oversized frames. To retain the natural proportion of an oval face shape, choose eyeglass frames that are the same width as (or broader than) the widest section of your face.

The sunglasses fit for oval-shaped faces would be wide around the eye, square, and Aviators. The thickness of the frame should be neither too thin nor too thick.


2. Long Shape

A long face shape elongates from the hairline to the chin. You have a long, rectangular, or oblong face shape if your forehead, cheeks, and jawline all seem to be the same width. The chin curves only slightly.

Celebrities with Rectangular-shaped faces: Alexa Chung, Meryl Streep, and Liv Tyler.

To make an oblong face appear shorter and more proportionate, try using frames that are deeper than they are wide. Glasses that do not spread beyond the widest part of your face would look good.

Choose larger styles to avoid offsetting your facial features. Round sunglasses and Aviators will complement the long face type.


3. Round Shape

A broad hairline and fullness below the cheekbones distinguishes the round face shape. Round faces have no angles, curved jawlines, and broad cheekbones. This face has fuller cheeks and chin.

Celebrities with Round-shaped faces: Ginnifer Goodwin, Mila Kunis, and Emma Stone.

Try using angular, narrow eyeglasses to extend a round face and make it look slimmer. Round faces complement larger, more angular styles. Rectangular or semi-rimless, bold color frames, or Wayfarers can give a smart look.


4. Square Shape

Strong jawlines and broad cheekbones highlight square faces. A square-shaped face features straight sides and a little curvature at the chin. This means that the ratio of vertical to horizontal is nearly proportionate.

Celebrities with Square-shaped faces: Cameron Diaz, Lucy Liu, and Rihanna.

Try thin frame designs, frames with more width than depth, and narrow ovals to broaden a square face and soften its angles.

Wearing round, wider sunglasses will help you balance out your square features. Softer styles of sunglasses, such as round and oval shapes, and dark upper rims or light lower rims, can complement the square appearance.


5. Heart Shape

A broad forehead and a narrow chin distinguish a heart-shaped face. We also known this facial shape as an inverted triangle.

Celebrities with Heart-shaped faces: Reese Witherspoon, Ashley Olsen, and Halle Berry.

Choose frame shapes that are broader at the bottom to lessen the perceived width of the top of the face. The sunglasses fit for heart-shaped faces would be geometric, circular, cat-eye, and frames with a wider bottom.

D-frame and medium Aviator styles are also suitable because their high arms warp the face downward and appear to add gravity to the bottom half of the face.


6. Diamond Shape

High cheekbones and a sharp chin define features with a diamond shape.

Celebrities with Diamond-shaped faces: Ashley Greene, Jennifer Love Hewitt, and Scarlett Johansson.

Try frames with elaboration or pronounced brow lines to draw attention to the eyes and flatten the cheekbones.

The sunglasses fit for diamond-shaped faces would be rectangle, oval, or cat-eye with bold colors. While round shapes will soften a sharp chin, D-frame sunglasses will balance out the wide cheekbones.

Types of Sunglasses


There are various types of sunglasses, and understanding the variations will prove helpful in selecting the pair that suits best for you. Their shape categorizes most sunglasses.


1. Aviator

The triangular-shaped metal frame glasses with smooth edges were originally designed to protect pilots' eyes during flight. Its long shape teardrop lenses can also balance features and create the illusion of a longer face. Aviator sunglasses are versatile and suitable for all face types.
