Everything About Credit Card Dimensions

What are the standard credit card dimensions in inches?

Sarah, a frequent traveler, nearly missed her flight when her new metal card didn't fit the airport kiosk. Like many, she didn't realize cards follow strict sizing. According to ISO/IEC 7810 ID-1 standard (2023 update), all major cards measure:

  1. Width: Precisely 3.375 inches (85.6 mm)
  2. Height: Exactly 2.125 inches (53.98 mm)
  3. Thickness: Typically 0.03 inches (0.76 mm)
Verify your card's compatibility using ISO's official specifications before purchasing premium metal cards.

  2. Metal cards: Range 0.039-0.059 inches
