The Beginner’s Guide to Poker Bet Sizing

As a poker player, understanding how to use bet sizes to influence and manipulate the action is critical when it comes to developing your poker game. Improper bet sizing is a common mistake among new players, as they often raise or bet at extremes — either too little or too much. Let’s take a look at some general bet-sizing guidelines in a typical online poker game.

Preflop Bet Sizing

Before making a bet, it’s important to consider the result you hope to achieve. When it comes to bet sizing before the flop, a good rule of thumb for beginners is to raise three times (3x) the big blind, plus one big blind for every limper in the pot. Using this formula in a cash game with blinds of $0.25/$0.50, your standard raise would be $1.50 (3x $0.50), but with two callers, you should raise to around $2.50 (3x $0.50 + 2x $0.50 for the limpers).

With that said, it’s important to adjust your bet sizing based on the tendencies of the players at the table and other situational factors. In some games, a 3x or 2.5x betting formula may not accomplish your goals, and you may need to increase your bet size. For example, if you are playing with a bunch of loose players who will call regardless if it’s a 3x or 5x, raising 5x with your value hands makes much more sense than it would against tighter players.

Isolating an opponent is a pre-flop raise (or reraise) when you want to limit the number of players you are up against. This is especially powerful in position following a number of limps or calls of an earlier raise. Depending on the type of opponents you are facing, and whether you have a value or bluff hand, you may want to slightly increase the 3x + 1x recommendation outlined earlier. Keep in mind that the effectiveness of pre-flop raises can vary depending on the table you’re on, so be ready to adjust your bets accordingly.

Postflop Bet Sizing

When it comes to bet sizing after the flop, a general rule of thumb is to bet between ½ the pot and the size of the pot. This will usually give draws incorrect odds to call and often times get better hands to fold (for example, you may get low pairs or better non-pair hands to fold to your draws when betting out on a scary board).

Value betting is another important concept in bet sizing. This involves wagering the maximum amount that someone will call. To be an effective value bettor, you need to know your opponents well and be confident that you have the best hand. Once this is settled, you can make the appropriate bet size to extract maximum value out of your hand.

When selecting your bet size, it’s important to be aware of the board texture and how it affects the range of hands your opponents may have. For example, if the board is very coordinated and your opponents are unlikely to call a big bet without a big hand, you’ll likely want to size down your value-bets to get a “crying call.” On the other hand, if you are facing an opponent that likes to hero-call and you are holding a big hand on a disconnected board, you can size up your value-bets and extract maximum value.

As you can probably tell, proper bet sizing is crucial in poker and can make a huge difference to your long-term bottom line. It’s important to consider the result you hope to achieve, adjust your bets based on the tendencies of the players at the table, and use proper bet sizing before and after the flop. With practice and experience, you’ll become better at navigating different situations and making the right bet at the right time.
