There are many denominations of poker chips, but most players only need a few. The most common denominations are 1, 2, 5, 10, and 20.
Other denominations include $5, $10, and $25 chips.
If you’re playing in tournaments, you’ll want to bring different denominations of chips. In tournaments, each player is given a stack of chips worth the same amount.
For example, in a tournament with a $100 buy-in, each player would be given 50 1-dollar chips, 20 2-dollar chips, 10 5-dollar chips, and 5 10-dollar chips. So if you’re playing in a tournament with a $200 buy-in, you’ll need at least 100 1-dollar chips, 40 2-dollar chips, 20 5-dollar chips, 10 10-dollar chips, and 5 25-dollar chips.
