Poker raise rules: how much you can raise and re-raise

In no-limit and pot-limit poker, a raise must be at least as big as the last bet or raise in the same betting round. If the big blind is $2, the smallest raise is to $4; if someone raises from $2 to $6, they’ve raised by $4, so the next re-raise must go to at least $10. The most you can raise depends on the game: your whole stack in no-limit, the size of the pot in pot-limit, and one fixed step in limit.

The rules below follow the Poker TDA rules used by most tournaments (2026 edition) and the house rules common in cash games, such as Robert’s Rules of Poker. Where they differ, we say so. After the rules come ten worked examples from different games and situations.

Bet, raise and re-raise: the terms

A bet is the first chips put in during a betting round. A raise increases a bet, and a re-raise increases a raise. After a raise, every other player must call the new amount, raise again or fold. If you’re new to the actions themselves, start with our guides to the call and the check.

Players also count raises by number. Before the flop the big blind counts as the first bet, so the open is the 2-bet, the first re-raise is the 3-bet, and the next one the 4-bet. After the flop the count starts again: bet, raise, then 3-bet.

The one term that causes real disputes is the amount. Under TDA rules, saying “raise” with a number means the total: facing a $20 bet, “raise 50” makes your bet $50, not $70. Many cash games follow the same convention, so say “raise to” and the total to be safe.

The minimum raise in no-limit

The minimum raise is the size of the last full bet or raise in the round. It’s measured by the increment, the amount added on top, not by the total. Here’s how that works in a $1/$2 game before the flop:

The same rule applies after the flop. If someone bets $20 and another player raises to $50, the raise is $30, so the next re-raise must be to at least $80.

“A raise must double the bet” is a myth that refuses to die. It’s true for the first raise, because the increment equals the bet. After that it isn’t: $20 raised to $50 can be re-raised to $80, not $100.

Straddles are the one place where cardrooms disagree. Robert’s Rules and many casinos treat a straddle as a third blind, so the first raise must be to at least twice the straddle: in a $1/$2 game with a $4 straddle, that’s $8. Other rooms count the straddle as a raise of $2 and allow a raise to $6. Ask before you play.

How much can you raise in no-limit, pot-limit and limit?

The minimum raise works the same in every structure. The maximum is what separates them.

No-limit

You can raise any amount up to all the chips you have on the table. Under table stakes rules, you can’t add money from your pocket during a hand, and you can’t be forced out of a pot for lack of chips: if you can’t cover a bet, you go all-in for what you have and play for the part of the pot you’ve matched.

Pot-limit

The largest raise is the size of the pot after you call. A quick formula: the maximum raise total equals three times the bet you’re facing, plus everything else already in the pot, including any calls of that bet.

For example, with $40 in the pot and a $10 bet in front of you, you can raise to $70: call the $10 to make the pot $60, then raise by that $60. Before the flop, the blinds count as the bet and the pot: in a $1/$2 game, the first player can raise to $7. Our Omaha rules guide walks through more pot-limit maths, since Omaha is the game where pot-limit is most common.

Limit

In fixed-limit games every bet and raise is one fixed step. In a $4/$8 game, bets and raises are $4 before the flop and on the flop, and $8 on the turn and river. Most games cap each round at one bet and three raises, though some cardrooms allow four.

The cap is one of the few places where cash games and tournaments differ. In many cash games the cap is lifted when only two players are left in the hand, so they can keep raising each other. Under TDA tournament rules, the cap stays in place heads-up, until the tournament itself is down to two players.

How many times can you re-raise?

In no-limit and pot-limit, as many times as you like: there’s no cap on the number of raises. In practice the betting ends when someone is all-in or everyone else has folded or called.

In limit poker, the cap above decides. Once a round has a bet and three raises, the remaining players can only call or fold.

Short all-ins: when the betting reopens

An all-in for less than a full raise is the situation players argue about most. In no-limit and pot-limit, such an all-in does not reopen the betting for players who have already acted. They can call the extra amount or fold, but they can’t raise. Players who haven’t acted yet in that round can still raise.

The reasoning is simple: a player who has already acted shouldn’t get a second chance to raise just because someone added a few chips. If the all-in is a full raise or more, the betting reopens for everyone as usual.

Two smaller rules complete the picture:

• Several short all-ins can add up. If two short all-ins together make at least a full raise, the betting reopens for players who acted before them. The minimum raise stays the size of the last full bet or raise.
• Limit uses a lower bar. In limit games, an all-in of at least half a bet counts as a full bet or raise and reopens the betting; less than half doesn’t.

How to raise correctly at a live table

Online, the software only lets you click legal amounts. Live, how you put the chips in decides what your bet is, and a few habits keep you out of trouble.

• Say it out loud. A verbal declaration in turn is binding. Saying “raise to 50” before touching chips is the safest way to raise.
• Use one motion. In no-limit and pot-limit, a raise must go in with one forward motion unless you’ve announced the amount first. Putting chips in and then reaching back for more is a string bet, and it isn’t allowed: the dealer will treat the first amount as your bet.
• Watch oversized chips. Facing a bet, a single chip bigger than the call, put in without a word, is only a call. To raise with it, say “raise” before it lands.
• Mind the 50% rule with several chips. Under TDA rules, if you silently put in several chips that are at least half a raise more than the call, you must make it a full minimum raise. Less than half, and it’s a call; the extra chips come back.

House rules vary, especially in cash games. Robert’s Rules, for example, let a player who says “raise” in a cash game bring chips in with more than one motion, which TDA tournament rules don’t allow. If you’re unsure, ask the dealer before the hand.

Raise rules in practice: worked examples

Rules make more sense with numbers attached. Each example below is a situation players often get wrong, with the ruling and the reason behind it.

1. Raising over a straddle

In a $1/$2 cash game, the player under the gun posts a $4 straddle and the next player wants to raise. Where the straddle counts as a third blind, as in Robert’s Rules, the minimum raise is to $8, twice the straddle. In rooms that treat the straddle as a $2 raise, a raise to $6 is legal. It’s a house rule, so this is one to check with the dealer.

2. A re-raise after the flop

In a four-way pot, the first player bets $20, the second raises to $50, and the third calls $50. The fourth wants to re-raise. The last raise was $30, so the minimum is $50 + $30 = $80. Doubling to $100 is allowed, but it isn’t required.

To make the sequence easier to follow, here it is step by step:

3. A short all-in before the flop

In a tournament with blinds of 500/1,000, a player opens to 2,500, a raise of 1,500. The small blind moves all-in for 3,000, only 500 more. Since 500 is less than a full raise, the betting doesn’t reopen: when the action returns to the opener, they can call the extra 500 or fold, but not re-raise.

4. Two short all-ins that reopen the betting

After the flop, Player A bets $100. Player B goes all-in for $140, then Player C all-in for $200. Each step was short of a full $100 raise, but together they add $100 to A’s bet. That’s a full raise, so the betting reopens for A, who can call, fold or raise. The minimum raise stays $100, so the smallest raise A can make is to $300.

5. Too few chips for a raise

Facing a $20 bet, a player silently pushes $32 into the pot. The extra $12 is more than half of a minimum raise ($20), so under the TDA 50% rule they must complete it to $40. Had they pushed $28, the extra $8 would be less than half, and the action counts as a call with $8 returned.

6. One big chip

Facing a $25 bet, a player drops a single $100 chip in without saying anything. That’s a call of $25, with $75 in change. If they had said “raise” before the chip landed, it would be a raise to $100, the full value of the chip.

7. A pot-sized raise in pot-limit Omaha

The pot is $40. Player A bets $10 and Player B calls $10. Player C wants to raise the maximum. Calling the $10 makes the pot $70 ($40 + $10 + $10 + $10), so C can raise by $70 to a total of $80. The formula gives the same answer: three times the $10 bet, plus the other $50 in the pot ($40 and B’s call).

8. The cap in a limit game

In a $4/$8 game on the turn, the betting goes $8, raised to $16, $24 and $32. That’s a bet and three raises, so the round is capped: everyone else can only call $32 or fold. If only two players were in the hand, many cash games would let them keep raising; in a TDA tournament with more than two players left, the cap would still apply.

9. A string bet

Facing a $20 bet, a player puts $20 forward, pauses, then goes back to the stack for $40 more without having said anything. That’s a string bet. The dealer will rule it a call of $20, and the extra chips go back.

10. “Raise 50”

Facing a $20 bet, a player says “raise 50”. Under TDA rules the stated amount is the total, so the bet is $50, a raise of $30. If the player meant to add $50 to the $20 call, they needed to say “raise to 70”.

When raising makes sense

The rules tell you what you can do; strategy tells you when. Most good raises have one of a few purposes:

• Value: getting more money in when your hand is likely best.
• Bluff or semi-bluff: winning the pot now, or with a draw that can still improve.
• Isolation: raising a weak player’s limp or bet to play them heads-up.
• Stealing: raising from late position to win the blinds.
