Card fans are a visual display created by spreading playing cards in an arc. Originating from magic and illusion, this technique requires manual dexterity and an understanding of the physical properties of playing cards. A well-executed card fan can showcase either the uniform back design or the unique faces of a deck, depending on its orientation of the deck of cards.

The cardistry involved in creating card fans has captured the attention of audiences, leading to the card fan’s incorporation into theatrical performances. Variations of card fanning have emerged – some cardicians can fan an entire deck in one hand.
