You're sitting in a $1/$3 game. Two players limp in front of you. You look down at A♠ K♦. You want to raise. But how much?
If you've read any poker book published in the last fifteen years, you probably know the "formula": raise to 3x the big blind plus one big blind per limper. In a $1/$3 game with two limpers, that's $9 + $3 + $3 = $15.
Here's the thing: that formula was designed for online poker in the mid-2000s. It works reasonably well in that context. But live $1/$3 poker in 2026 is a completely different animal, and the $15 raise into a pot with two limpers is often leaving money on the table — or worse, failing to accomplish its purpose entirely.
The Goal of Raising Limpers
Before we talk about sizing, let's talk about why you're raising limpers in the first place. You have three objectives:
- Thin the field. You want fewer opponents postflop. Your premium hands play better against one or two players, not five.
- Build the pot with a positional advantage. When you raise in position, you want a bigger pot because you'll have more information on every street.
- Charge draws and weak hands. Limpers often have speculative hands — suited connectors, small pairs, suited aces. You want to make them pay a premium to see a flop.
The right raise size is the one that accomplishes all three of these goals against the specific players at your table. And at a typical live $1/$3 game, that size is almost always larger than the formula suggests.
Why $15 Doesn't Cut It
At most $1/$3 tables, a $15 raise into two limpers gets called by everyone. You end up in a $60+ pot, four ways, with ace-king — which is not where you want to be. Ace-king wants to play for stacks preflop or heads-up postflop. Four-way, you're going to miss the flop two-thirds of the time, and when you do flop an ace, you have three opponents who might have two pair or better.
The problem is straightforward: $15 is cheap. The limpers already put in $3. They're being asked to put in $12 more to win a pot that will be at least $30 and probably more. That's 2.5-to-1 or better, which is a price most recreational players will happily pay with almost any two cards.
The Right Sizing: Dollars, Not Multiples
At a typical $1/$3 game, effective raise sizes against limpers look something like this:
- One limper, tight table: $12 to $15
- One limper, loose table: $15 to $20
- Two limpers, any table: $20 to $25
- Three or more limpers, any table: $25 to $35
- Straddled pot with limpers: Add $10 to $15 to all of the above
These aren't arbitrary numbers. They're calibrated to the price elasticity of live $1/$3 players. Most recreational players have a psychological threshold — a number that makes them think twice about calling. At $1/$3, that threshold is usually somewhere around $20 to $25. Below that number, they call with anything. Above it, they start to tighten up.
Hand Example: Sizing That Actually Works
You're in a $1/$3 game with $300 effective stacks. A loose-passive player limps from under the gun. Another loose player limps from middle position. You're in the cutoff with K♠ K♥.
Bad sizing: You raise to $15. Both limpers call, plus the big blind. Four players see the flop. Pot: $61.
The flop comes A♥ 7♣ 4♦. The big blind checks, UTG checks, MP checks. You bet $35, one player calls. The turn is a Q♠. Opponent checks, you check back nervously. River is a 3♣. Opponent bets $50. Do they have an ace? Did they call preflop with A-8 suited? You don't know, and now you're in a marginal spot with an overpair in a bloated, multiway pot.
Good sizing: You raise to $25. One limper calls, everyone else folds. Two players see the flop. Pot: $56.
The flop comes A♥ 7♣ 4♦. One opponent to worry about. You make a smaller c-bet of $30. Opponent folds their 9♠ 8♠. You take down the pot without drama.
The extra $10 preflop completely changed the trajectory of the hand. Fewer opponents means more clarity, more control, and fewer cooler situations.
Adjusting for Opponent Type
The optimal raise size also depends on who's doing the limping.
Against a nit limper: This is unusual — nits don't limp often. When they do, it's usually a hand like small pairs or suited aces. A standard $15 to $18 raise often isolates them, and they'll fold to a c-bet on most flops they miss.
Against a loose-passive limper: These players call a wide range preflop but play passively postflop. Raise to $20 to $25 and plan to value bet every street when you connect. Their passive postflop tendencies make them ideal opponents in heads-up pots.
Against a maniac limper: Maniacs sometimes limp with strong hands to trap. A raise to $20 is fine, but be prepared for a big re-raise. If a known maniac limp-raises, respect it — this is one of the rare situations where a recreational player's unusual action means exactly what it looks like.
The Straddle Adjustment
Straddle pots are common in live poker and they change the math significantly. In a $1/$3 game with a $6 straddle, the effective big blind is now $6, not $3. Your raise sizes need to adjust accordingly.
With a straddle and two limpers, a raise to $30 to $40 is not unreasonable. It sounds like a lot, but remember — the pot already has $18 to $24 in it from the straddle and limpers. You're raising to about 5x the straddle, which is proportionally the same as raising to $15 in a non-straddled pot.
Don't be afraid of big numbers. Your opponents aren't thinking in terms of multiples. They're thinking, "Is $35 too much to call with jack-ten suited?" For most recreational players, the answer is yes — and that's exactly the outcome you want.
Common Mistakes With Limper Raises
Using the same size every time. If you always raise to $15, your opponents learn that $15 is "just what you do" and they stop giving it credit. Varying between $15 and $30 based on the situation keeps opponents guessing and ensures you're sizing appropriately for each spot.
Raising too small because you're worried about being "pot committed." At $300 effective stacks, a $25 preflop raise is 8% of your stack. You're nowhere close to committed. You can still fold to a three-bet or abandon the hand postflop if the board is terrible.
Not raising at all because "everyone calls anyway." Even if everyone calls, you've built a bigger pot with a range advantage. But more importantly, this mentality is often wrong — players do fold to larger raises. You just haven't tried large enough.
Practice Your Preflop Sizing
Preflop decisions set the tone for the entire hand. Getting the raise size right against limpers is one of the highest-impact adjustments a live $1/$3 player can make, and it's a skill that benefits from deliberate study.
