If we are talking about cards made of cardboard or paper containing personal or business-related information, these cards have different dimensions than personal credit cards. A typical business card measures 3.5 inches in width by 2 inches in height, or 8.89 cm x 5.08 cm for those using metric units. As for business credit cards, they have the same dimensions as personal credit cards, as they must comply with the ISO/IEC 7810 standard. The weight of business credit cards may vary, and some issuers may use metal or plastic materials to create the cards.
