What are the dimensions of a standard credit card?

Explanation:
Credit cards follow a universal size defined for compatibility with wallets, ATMs, and card readers. The exact standard is 85.60 mm by 53.98 mm, which in centimeters is about 8.56 cm by 5.398 cm. In everyday terms this size is commonly rounded to roughly 8.5 cm by 5.4 cm. That rounding is why the option with 8.5 cm by 5.4 cm best matches the standard. The other dimensions would be noticeably off from the official size and could cause fit or recognition issues.
