How many card are in a hand in Magic the gathering?

Answer 1

At the beginning of the game Seven.

During the game, you can have a unlimited numbers of cards in hand.

However, during your discard phase (before the end of the turn) if you have more than seven, you must discard as many cards to keep seven (except when a spell (enchantment) or a effect in play authorizes more than seven cards during this phase).

NB: Starting hand sizes can be modified during game variants, like Vanguard.

Answer 2

You should allways try to have the minimum amount of cards in your deck. The minimum for most formats is 60 cards.
