A deck of 52 cards contains 12 face cards. Face cards are those with a king, queen or jack on them. Since there are four suits and each suit contains one of each type of face card, there are four kings, four queens and four jacks in a deck.
Hearts and diamonds are the red suits, and clubs and spades are the black suits. Each suit has 13 different cards in it. In addition to the face cards, each suit also has an ace and numbered cards from two through 10. Depending on the card game and the situation, the ace is ranked either below the two or above the king.
