Sunglasses Size Guide
Lens (50) Bridge (20) Temple (140)

Finding the perfect fit is just as important as finding the perfect style. All FeltzGood frames feature standard sizing numbers printed on the inside of the temple arm (e.g., 50-20-140).

  • Lens Width (50): The horizontal width of one lens. Determines how wide the frame sits on your face.
  • Bridge Width (20): The distance between the lenses. Affects how the glasses sit on your nose.
  • Temple Length (140): The arm length from hinge to tip. Ensures the glasses sit securely over your ears.
Frame Size Lens Width Best For
Small / Narrow Under 50mm Vintage/steampunk styles, narrow faces
Medium / Standard 50mm - 54mm Average face widths
Large / Oversized 55mm+ Oversized square/cat-eye styles
FeltzGood Credit Card Measurement Test

The Credit Card Test

Need a quick way to measure? A standard credit card is exactly 54mm wide. Hold one vertically against the center of your nose (as shown):
• If the edge ends perfectly at the outer corner of your eye, you are a Medium.
• If the card extends past the edge of your eye, you are a Small.
• If the card doesn't reach the edge of your eye, you are a Large.
