The Standard Size: 85.60 mm x 53.98 mm

The vast majority of credit cards adhere to the ISO/IEC 7810 ID-1 standard, which specifies dimensions of 85.60 mm x 53.98 mm (3.370 in x 2.125 in). This standard ensures compatibility with card readers, ATMs, and other devices worldwide.

Variations and Exceptions

While the standard dimensions are widely accepted, some exceptions exist:

• American Express: American Express cards measure slightly wider at 85.60 mm x 53.98 mm (3.370 in x 2.165 in).
• Japan: Japanese credit cards follow the JIS X 6301 standard, which specifies dimensions of 85.60 mm x 53.98 mm (3.370 in x 2.125 in) but with rounded corners.
• China: Chinese credit cards comply with the GB/T 2381-2008 standard, which sets dimensions of 85.50 mm x 54.00 mm (3.366 in x 2.126 in), slightly wider than the ISO standard.
