What is the difference between bridge and poker playing cards?
The difference between bridge cards and poker cards is simply one of size: poker cards are wider than bridge cards.





Bridge card size: The card is approximately 3.5 inches high and 2.25 inches wide.





Poker card size: The card is approximately 3.5 inches high (same as the bridge card, obviously) and 2.5" wide.





So poker cards are about .25 inches wider than bridge cards.

You have to hold many more cards in bridge than in poker, so they are thinner.
Reply:Both types of playing card packs are the same. They include the standard 52 card deck plus 2 jokers. The decks that are different are the euchre and the pinochle decks (each have 48 cards in the deck, usually from 9 to Ace, and no jokers).
Reply:Both decks are the same with 52 cards and two jokers, but the difference is the size. A poker deck is about 3/16 of an inch wider.
