What is the size of a business card?

In the United States, standard business cards are 3.5 inches wide by 2 inches high. Cards may be designed in a horizontal or vertical orientation.

Business cards are designed to list key contact information about an individual. To ensure that business cards are elegant and attractive, designers often use bold or a slightly larger font size to showcase the individual's name or the business name. Well-designed business cards include at least one method of contacting the individual, either a mailing address or a phone number. Ideally, a business card includes two or more methods of reaching the person and some visual way to nudge one towards the preferred contact method.
