Glasses Size Guide

How to Find Your Perfect Fit

Choosing the right size for your eyeglasses or sunglasses ensures comfort and optimal vision. Follow these steps to determine your size:


1. Understand Eyewear Measurements

Each pair of glasses has three key measurements, typically printed on the inside of the temple arm (e.g., 52-18-140):

  • Lens Width (mm): The horizontal width of each lens.
  • Bridge Width (mm): The distance between the lenses.
  • Temple Length (mm): The length of the arm from the frame to the ear.

2. Size Chart


Size Lens Width (mm) Bridge Width (mm) Temple Length (mm) Face Type
Small 48-52 16-18 130-135 Narrow Faces
Medium 53-56 18-20 135-140 Standard Faces
Large 57+ 20+ 140+ Wider Faces

3. Measure Your Face

Use a ruler or tape measure to check these dimensions on your current eyewear or face:

  • Width of your face: Measure from temple to temple.
  • Width of your bridge: Measure the distance across your nose.
  • Arm length: Use a pair of glasses that fits you well and measure the arm.

4. Tips for Choosing the Right Size

  • Small Faces: Look for frames with a lens width of 48-52mm.
  • Medium Faces: Opt for frames in the 53-56mm range.
  • Large Faces: Choose frames with a lens width of 57mm or more.
