Choosing eyeglasses is not just about finding an attractive design. The shape and size of the frame, as well as how it fits your face, all influence visual balance and everyday comfort. With so many eyeglass styles available for different face shapes, finding the right pair may not be immediately obvious.

In this guide, you'll learn how to identify your face shape, discover frames that complement your features, and choose the right size before purchasing your new eyeglasses from Okyali.


How to Determine Your Face Shape Before Choosing Eyeglasses

Stand in front of a mirror with your hair pulled away from your face and look straight ahead. Compare the width of your forehead, cheekbones, and jawline, then observe the length of your face from your forehead to your chin.


If your face is longer than it is wide, with soft contours, it may be oval-shaped. If you have a broad jawline with well-defined angles, your face may be square. If your face has similar proportions in length and width, with rounded cheeks, it is more likely to be round. A triangular face, on the other hand, typically has a noticeable difference between the width of the forehead and jawline.


Remember that identifying your face shape when choosing eyeglasses is only a starting point, not a strict rule. Your features may combine characteristics of more than one face shape, and your final choice should also depend on frame size and personal preferences.


Best Eyeglasses Styles for Different Face Shapes

Best Eyeglasses for Oval Faces

Oval faces are generally longer than they are wide, with balanced forehead and jaw proportions and softly curved contours. These proportions offer flexibility when experimenting with different frame styles.

Cat-eye frames are a suitable choice for those who prefer to accentuate the upper part of the face with slightly upswept corners. Aviator frames, meanwhile, introduce flowing lines and distinctive details. Ideally, the frame should be close to the width of your face without extending excessively beyond the sides.


You can explore the Armani Exchange AX 3096U 8158, featuring a black cat-eye frame, making it an option for those who prefer frames with elevated outer corners.

If you prefer an aviator style, take a look at the Ray-Ban RB 6589 2503, featuring a black metal frame with a design inspired by classic pilot glasses.


Best Eyeglasses for Square Faces

Square faces typically feature a defined jawline, a relatively broad forehead, prominent angles, and similar proportions in facial length and width.

Round frames can create visual contrast with the straight lines of the jaw, while hexagonal frames combine geometric angles with softer edges. Aviator designs also appeal to those who prefer curved frame lines rather than traditional square frames.


One option worth trying is the Gucci GG1125OA 003, featuring a silver metal hexagonal frame that introduces geometric contrast to the angular features of a square face.

For those who prefer round frames, the Silhouette 9030 2931 features a black round design with a 51 mm lens width, making it another option worth comparing with hexagonal frames.


Best Eyeglasses for Round Faces

Round faces are characterised by relatively similar facial length and width, fuller cheeks, and soft contours without prominent angles.

Rectangular and square frames often create contrast with the natural roundness of the face through their straight lines and defined corners. Geometric frames can provide a similar visual effect, particularly when they feature well-defined edges without being excessively wide.


If you prefer square frames, consider the Ray-Ban RB 7185 8235, featuring a blue plastic frame with defined lines that create visual contrast with the softer features of a round face.

For another option with a rectangular design, explore the Carrera CAR 293 807, featuring a black frame and straight lines suited to those who prefer a more structured appearance.


Best Eyeglasses for Triangular Faces

Triangular faces are characterised by a difference in width between the upper and lower parts of the face. In a traditional triangular face shape, the jawline is generally wider than the forehead.

Most frame shapes are worth exploring, including aviator, cat-eye, square, and round designs. Cat-eye frames draw attention to the upper part of the face, while round frames introduce a softer visual contrast with the jawline. Square frames can also suit those who prefer a more defined style, provided the frame width is proportionate to the face.


One option to consider is the Armani Exchange AX 3096U 8158, featuring a cat-eye design that emphasises the upper part of the frame and creates visual balance with a wider jawline.

You can also try the Oakley OO 8140 03, featuring a square design and black frame, making it an option for those who prefer defined lines and a sporty aesthetic.



How to Choose the Right Eyeglasses Size for Your Face

Even when you choose a frame shape that complements your facial features, selecting the correct size remains essential for comfort and stability.

To find the right eyeglasses size for your face, pay attention to the following factors:

  • Frame Width: Ideally, the frame should match the width of your face without putting pressure on the sides or extending too far beyond them.
  • Lens Width and Height: These dimensions influence the overall size of the frame and its position relative to your eyes and eyebrows.
  • Temple Length: The temples should allow the glasses to rest securely behind your ears without causing uncomfortable pressure.
  • Nose Bridge: The bridge should sit comfortably on your nose without frequent slipping or noticeable pressure.


Two Ways to Find Your Ideal Eyeglasses Size

1. Check the Size of Your Current Eyeglasses

If you already own a comfortable pair of eyeglasses, you can use their measurements as a reference when purchasing a new pair. You will usually find three numbers printed on the inside of the temple, such as 53-18-140.

These numbers indicate the lens width (53 mm), bridge width (18 mm), and temple length (140 mm), respectively.

Compare these measurements with the specifications of your new eyeglasses at Okyali, keeping in mind that similar measurements do not necessarily mean the frames will have identical overall widths or fit your face in the same way.


2. Estimate Your Size Using a Credit Card

If you do not have a previous pair of eyeglasses, you can use a standard-sized credit card to estimate a suitable lens width.

Stand in front of a mirror and hold one edge of the card vertically against the centre of your nose. Then observe where the opposite edge falls in relation to the outer corner of your eye.


According to the approximate sizing guide shown in the image:

  • Small Size: If the card extends beyond the outer corner of your eye, a lens width of 55 mm or less may be suitable.
  • Medium Size: If the card ends approximately at the outer corner of your eye, try a lens width between 56 and 61 mm.
  • Large Size: If the card ends before reaching the outer corner of your eye, try a lens width of 62 mm or more.


These measurements are general guidelines rather than fixed rules, as lens size alone does not determine how well a pair of eyeglasses fits. Be sure to check the overall frame width, nose bridge comfort, and temple length before purchasing.
