The right pair of eyeglasses helps you see better, but wearing glasses can also boost your self-confidence and allow you to express your unique sense of style. Today’s eyeglass frames come in more silhouettes, colors and shapes than ever before. 

But with so many options to choose from, finding the perfect pair of glasses can be tricky. 

To ensure your new eyeglasses will be as comfortable, flattering and functional as possible, it’s important that you choose frames that fit your face properly. 

While your optician checks the fit of your glasses when you order them in your eye doctor’s office, if you’re buying glasses online, you will want to know a bit more about how to make sure your glasses fit properly. Improperly fitting glasses can result in eye strain, headaches, dizziness and even nausea.

Here are a few tips on how to ensure the right eyeglass frames fit for your face.

The right width for your face

Most eyeglass frames have three numbers stamped inside them. These three measurements tell you the size of the frames:

  1. The lens width
  2. The bridge size (distance between the lenses)
  3. The temple length (distance between the frame hinge and back tip of the temple)

You’ll want to select eyeglass frames with a total width that matches the width of your face.

Small adult faces can be as much as 20 millimeters narrower than wider faces, so it’s important to choose a frame width that will fit you appropriately. Properly fitting frames won’t hang off the sides of your face (indicating they’re too wide). 

If you’re looking directly at your glasses from the front, the sides of the temples should not be visible (this means they’re too narrow.)

Eyes centered in the lens 

When gazing straight ahead, each of your pupils should be directly centered, from left to right, in the lens. The distance between the corner of the eye and the lens edge should be the same on both sides.

In general, your eye should take up the top half of the lens. Your lower eyelashes should fall roughly at its vertical midpoint.

Frames centered on your face

The frames should sit in the middle of your face. The distance between the top of the frames and the top of your head should be roughly equal to the distance between the bottom of the frames and the base of your chin. 

Properly fitting frames will create a sense of visual balance.

Remember, at least half of your eyebrows should be visible above the top of the frame.

Proper temple length

The temples should be long enough that you can adjust them to fit around your ears securely and comfortably.

You should be able to move, bend and shake your head without your glasses slipping out of position or sliding down your nose. 

The weight of the frames should be balanced evenly across the bridge of your nose or equally distributed on the frame’s nose pads.

Flattering frame shape and color

Your eyeglass frames should be chosen to complement your face’s unique shape.

The most flattering glasses for round-shaped faces, for instance, are usually square, rectangular or Wayfarer styles. Square-shaped faces often look best with oval or round frames. 

There are no hard-and-fast rules, however: The best glasses for you are those that fit well, are in proportion to your face’s size and suit your skin tone and coloring. Feel free to try on multiple pairs — the one that looks best may surprise you.

Find an eye doctor near you to discover the best frame size for your face and find flattering and stylish choices to suit your face.
