How to Choose the Perfect Sunglasses Size for Your Face

Finding the right pair of sunglasses isn't just about style; it's about comfort and fit, too. The key to picking a pair that complements your face is understanding your correct sunglasses size. But don't worry, we’ve got you covered! In this blog, we’ll break down everything you need to know about finding your perfect fit.



Why Sunglasses Size Matters

Wearing sunglasses that don’t fit properly can not only be uncomfortable but also compromise their effectiveness. Sunglasses that are too big may slide down your nose or feel awkward on your ears, while too-small frames might pinch or not provide enough coverage to protect your eyes from UV rays.

Understanding Sunglasses Measurements

Most sunglasses are measured in three key areas:

  1. Lens Width: This refers to the horizontal width of one lens, typically ranging between 50mm to 60mm for adults.
  2. Bridge Width: This is the distance between the two lenses, determining how the sunglasses sit on your nose. It’s usually around 14mm to 24mm.
  3. Temple Length: The length of the "arms" of the sunglasses that rest on your ears. Standard sizes fall between 120mm and 150mm.

How to Measure Your Face for Sunglasses

To choose the right size, start by measuring your face. Here’s a simple method:

  1. Measure the width of your face from temple to temple.
  2. Compare your face width to the lens width of the sunglasses.
  3. Ensure the bridge width provides a comfortable fit across your nose.

Frame Shapes and Face Shapes

Different face shapes suit different frame styles. Here’s a quick guide:

  • Round faces: Opt for square or rectangular frames to add contrast.
  • Oval faces: Most shapes work well, but oversized frames can enhance your natural symmetry.
  • Square faces: Round or oval frames can soften strong angles.
  • Heart-shaped faces: Cat-eye or rounded frames balance wider foreheads and narrower chins.

Final Tips

When trying on sunglasses, make sure they feel comfortable and don’t slip down your nose. The lenses should also cover your eyes fully for maximum UV protection.
