How to Find Your Face Shape?

Determining your face shape is the first step in finding the perfect smart glasses to complement your unique features. By looking in the mirror or seeking help from a friend, you can easily identify your face shape. However, if you're unsure, follow these simple steps to accurately determine your face shape:

  1. Measure your face: Use a tape measure or ruler to measure the widest part of your face, usually across your cheekbones.
  2. Measure your jawline: Measure the distance from the tip of your chin to the point where your jawline begins beneath your ears.
  3. Measure your forehead: Measure the widest part of your forehead, usually across your brow line.
  4. Measure your face length: Measure the distance from the center of your hairline to the tip of your chin.
  5. Determine your face shape: Use the measurements to identify your face shape.
  • If your forehead and jawline widths are equal, and your face length is shorter than your cheekbones width, you have a square face.
  • If your forehead and cheekbones are the same width and your face length is longer than your jawline, you have an oval face.
  • If your forehead, cheekbones, and jawline widths are nearly equal, you have a round face.
  • If your face is longer than it is wide, with a pointed chin, you have a heart-shaped face.
  • If your face length is greater than your face width and your forehead, cheekbones, and jawline widths are roughly equal, you have a rectangular face.
  • If your cheekbones are the widest part of your face, and your forehead and jawline are narrow and roughly equal in width, you have a diamond-shaped face.

Following these steps, you can easily determine your face shape. Now it's time to match your face shape with various styles of smart audio glasses.

Smart Audio Glasses for Diamond Face

Cat-eye, oval, and rimless frames are excellent choices for diamond-shaped faces. These frames help soften the sharp angles of the face and draw attention to the eyes. Avoid narrow frames that emphasize the narrow forehead and jawline.

For diamond-shaped faces, we recommend our SangStre 5025 frames, which feature a subtle cat-eye shape and bold brow line that attract attention while balancing wider cheekbones.

Square Face Smart Audio Glasses

Round, oval, and cat-eye frames are good choices for square faces. Round frames add a touch of softness to the angular features of square faces, while oval frames create a harmonious balance. Cat-eye frames are also a great choice, as they draw attention to the upper half of the face, balancing a strong jawline.

For those who like angular features, square frames with rounded edges would be suitable. These frames offer a bold and modern look while still complementing the strong lines of a square face.

Try the SangStre 6133 for this face shape.

Smart Audio Glasses for Round Face 

Round faces tend to have softer, more curved features, so it's essential to choose frames that add definition and angles to the face. Angular frames with straight lines and sharp corners help balance the roundness of the face.

Square or rectangular frames can add structure to the face, while cat-eye frames with upturned corners create a more attention-grabbing appearance. Oversized frames are also suitable for round faces, as they can make the face appear slimmer and longer.

When choosing frames for a round face, it's best to avoid circular or oval frames, as they can accentuate the roundness of the face. Instead, opt for frames with distinct lines and angles to create a more balanced look. The SangStre 5035 model is an excellent choice for round faces, featuring a rectangular shape with slightly curved edges, perfectly enhancing facial definition.

Smart Audio Glasses for Heart Face 

For heart-shaped faces, the goal is to create balance between the forehead and chin while accentuating the eyes and cheekbones.

Look for frames with a wider bottom, such as aviator or butterfly frames, as they help create the illusion of a broader chin. Avoid top-heavy or overly detailed frames, as they draw attention to the forehead and make the chin appear smaller. Additionally, consider frames with curved edges, like cat-eye or round styles, as they can soften the angular lines of the face.

The SangStre 5146 is well-suited for this face shape.

Smart Audio Glasses for Oval Face 

Oval faces are the most versatile, able to accommodate almost any frame style. However, it's best to choose frames that are proportional to the face shape, not too large. Look for frames with soft, rounded edges that complement the natural curves of the face.

Oval faces can also pull off more angular shapes, like rectangular, square, or geometric frames. These styles can add facial definition, creating a strong, refined appearance.

Some recommended frame styles for oval faces include classic wayfarer frames, round frames, aviator frames, cat-eye frames, and butterfly frames. The SangStre 5146 glasses are an excellent choice for oval faces, featuring a modern and classic aviator style with fashionable metal frames and polarized lenses.

Smart Audio Glasses for Rectangular Face 

For individuals with a rectangular face shape, the key is to choose frames that add width and soften the angular features of the face. Frames with rounded edges or curves help create the illusion of a wider face, balancing the length.

Oval and round frames suit rectangular faces, and cat-eye frames with softer edges are also suitable. Look for frames with a high bridge, which can help shorten the appearance of a long face. Avoid using rectangular or square frames, as they can further accentuate the face's angular features.

The SangStre 5240 is a recommended pair of glasses for rectangular faces. This oval frame has rounded edges, softening the chin line and adding width to the face. The high bridge also helps shorten the appearance of a long face, making it a charming choice for rectangular face shapes.


It's crucial to find the right smart glasses for your unique face shape. By determining your face shape and understanding which frames suit you best, you can choose the perfect smart glasses that are not only comfortable to wear but also enhance your overall appearance.
