Poker Size

Poker size cards are the most common type of playing card. They are 2.5 inches wide and 3.5 inches tall. Poker size cards are used in most card games, including poker, blackjack, and bridge.

Bridge Size

The standard size for Bridge playing cards is 2.25 inches wide x 3.5 inches tall, or 58 mm x 89 mm. This size is also commonly called “Bridge Size.” While this is the most popular and well-known size for playing cards, it is not necessarily the only option available.

Other sizes you might encounter include “Poker Size,” which measures 2.5 inches wide x 3.5 inches tall, or 63.5 mm x 88 mm; and “Mini Size,” which shrinks things down to 1.75 inches wide by 2.5 inches tall, or 44 mm x 63 mm—about the size of a credit card.

There are also jumbo sizes and even larger ones used for novelty purposes, though these are less likely to be used in serious card games. The important thing to remember is that all standard playing cards—whether Bridge Size, Poker Size, or Mini Size—will have dimensions that are in a 3:2 ratio; that is, for every 3 units of length, there will be 2 units of width. So, if you know one dimension (either the width or the height), you can easily calculate the other one.

Jumbo Size

A playing card is a piece of specially prepared card stock, heavy paper, thin cardboard, plastic-coated paper, cotton-paper blend, or thin plastic that is marked with distinguishing motifs. Playing cards are typically palm-sized for convenient handling, and were first invented in China during the Tang dynasty.


In the United States playing cards measuring 8.75 inches by 6.75 inches are considered oversize or jumbo cards. These card are often used in Svengali decks which are popular with magicians. Jumbo cards can also be used for games such as Acey-Deucey and Old Maid. Some people collect jumbo cards as a hobby.
