Before you pick a size, ask one question: what do you want your opponent to do? Call with worse, fold something better, or pay to see the next card. The answer tells you how much to bet.
Start with the job
- Value bets want calls from worse hands. Bet as much as those worse hands will still call.
- Bluffs want folds from better hands. Bet enough that calling is uncomfortable, but no more than you need to.
- Protection bets charge hands that would love a free card, like flush draws and overcards.
Sizes are usually described as a fraction of the pot. In a $60 pot, a third-pot bet is $20, a half-pot bet is $30 and a pot-sized bet is $60.
Small bets
Small bets, about a quarter to a third of the pot, risk less and keep weak hands calling. They work well when the board favours you and your opponent can’t do much about it.
Example: at $1/$3 you raise to $12 on the button with A♣K♦ and the big blind calls. Pot $25. The flop is K♥8♠3♣. You bet $8. Worse kings, eights and small pairs call. A bigger bet would mostly fold out the hands you want to get money from.
The downside: a small bet gives your opponent a good price. Against a flush draw, $8 into $25 is a cheap call.
Big bets
Bigger bets, around two-thirds of the pot or more, get more money in when called and put more pressure on the hands that fold. They make sense on wet boards and when your hand is either very strong or a bluff, with little in between.
Example: you have 9♠9♦ on J♥9♥4♣ with $80 in the pot. You have a set, and any heart, ten, queen or eight could hurt you. Bet $55 to $60. Flush draws and straight draws pay a real price, and top pair has a hard time folding.
Stacks cap the plan
Before you bet, look at what will be left behind. The stack-to-pot ratio (SPR) is the effective stack divided by the pot at the start of the flop. A low SPR means you’re close to committed. A high SPR means there’s room for several streets of betting.
Live games create low SPRs fast. At $1/$3 with $150 stacks, a raise to $15 with three callers makes a $61 pot. The SPR is about 2. A half-pot flop bet of $30 leaves about $105 behind, which is less than the pot will be after a call. If you have top pair, you’re usually going all the way. Plan for that on the flop instead of finding out on the turn.
With deep stacks it goes the other way. At $2/$5 with $1,000 behind in a $50 pot, you have room for three streets. Bet sizes that grow each street (say $35 on the flop, $90 on the turn, $250 on the river) can get stacks in when you have the nuts.
See cash-game buy-ins for how your buy-in sets your stack depth.
Don’t let your size give away your hand
A common live leak: betting big with strong hands and small with weak ones. Regulars notice. If $40 always means a set and $10 always means a draw, you’re playing face up. Pick sizes by board and situation, and use the same size with your value hands and your bluffs in the same spot.
Live sizing notes
- Preflop opens are bigger live than online. At $1/$3, $10 to $15 is common, plus about $3 per limper.
- Players call more at live low stakes. Value bet bigger and bluff less against players who don’t fold.
- Say the amount out loud, like “bet twenty-five”, before moving chips. It avoids string-bet problems. See live poker etiquette.
FAQ
What is a standard bet size in poker?
There isn’t one. Most postflop bets fall between a third of the pot and the full pot. Use smaller sizes on dry boards and bigger ones on wet boards or when your hand is very strong or a bluff.
How much should I raise preflop in a live game?
At $1/$3, an open of $10 to $15 is common, plus about one big blind for each player who limped in before you. Keep the same size with all the hands you open from a given seat.
What is an overbet?
A bet bigger than the pot, such as $120 into $80. It is used with very strong hands and bluffs when the board makes it hard for the opponent to have the nuts.
Does a bigger bet mean a stronger hand?
It shouldn’t. If your size always matches your hand strength, observant players can read you. Choose sizes by the board and situation, not by how much you like your cards.
