C-Bet Sizing Calculator

Get optimal continuation bet sizing recommendations based on board texture, range advantage, opponent type, and number of opponents in the pot.

C-bet sizing calculator quick answer

A good c-bet size depends on board texture, range advantage, opponent type, and the number of players in the pot. Use 25-33% pot on dry boards you hit often, 50-66% pot on medium boards, and 66-100% pot on wet boards where value hands need protection. Check more often in multiway pots.

Dry high-card flop: 25-33% pot works well when the preflop raiser has range advantage.
Wet connected flop: 66-100% pot is better with value hands and strong draws.
Multiway pot: c-bet less often because at least one caller connects with the board more often.
Calling station opponent: value bet larger and remove most pure bluffs.

Common c-bet sizing chart

Use these flop sizing defaults as a starting point, then adjust for stack depth and opponent tendencies.

Flop type	Example board	Default c-bet size	Why it works
Dry high-card board	K-7-2 rainbow	25-33% pot	The raiser has more top pair and overpair hands, and there are few draws to charge.
Paired dry board	Q-6-6 rainbow	25-33% pot	Small bets pressure missed hands while keeping bluffs cheap.
Medium connected board	T-8-4 two-tone	50-66% pot	Pairs and draws can continue, so value hands need a real price.
Wet connected board	J-T-9 two-tone	66-100% pot or check	The caller connects often. Bet big with strong value and good draws, or check weaker hands.
Low connected board	6-5-4 rainbow	Check often	The caller has more sets, straights, two pair, and pair-plus-draw hands.
Multiway pot	Any coordinated flop	Check often; bet 50-75% with value	More opponents means someone connects more often, so pure bluffs lose value.

C-bet adjustments by opponent

The board gives you the first sizing estimate. The opponent tells you whether that estimate should move up, down, or become a check.

Opponent type	Best adjustment	Hands to bet	Hands to check
Calling station	Bet larger for value	Top pair good kicker, overpairs, strong draws	Air and weak backdoors
Tight folder	Use small frequent bets	Thin value, overcards, backdoor draws	Showdown-value hands that dislike a raise
Aggressive raiser	Check more medium strength	Hands that can call or 3-bet a raise	Marginal top pair, second pair, weak draws
Fit-or-fold regular	Bet small on dry boards	Range advantage boards and cheap bluffs	Boards that smash their flatting range
Unknown player	Start with board texture	Clear value and good semi-bluffs	Hands with weak equity and no blockers

Frequency Recommendation

C-bet ~70-80% of the time (dry/paired, heads-up)

Heads-up c-betting frequency depends heavily on board texture. Dry boards favor high-frequency small bets; wet boards favor lower-frequency large bets.

Why This Sizing?

•Board texture: Dry (e.g., K-7-2 rainbow) — base size 30% of pot.
•Range advantage: You have the stronger range — add 10% pot to extract more value.
•Opponent: TAG — no adjustment, keep balanced.
•Players in pot: Heads-up — standard c-bet frequency applies.

Standard C-Bet Sizes by Board Texture

Board Texture	Example	Size (% Pot)	Frequency
Dry	K-7-2 rainbow	25-33%	70-80%
Paired	T-T-3 rainbow	25-33%	70-80%
Semi-Wet	Q-J-5 two-tone	50-66%	55-65%
Wet / Dynamic	T-9-8 two-tone	66-100%	40-50%
Monotone	A-9-4 one suit	33-50%	25-35%

These are solver-informed baselines for single-raised pots. 3-bet pots typically use smaller sizes (25-40% pot) due to higher stack-to-pot ratios.

The Continuation Bet Explained

A continuation bet (c-bet) is a bet made on the flop by the player who raised preflop. Because the preflop raiser usually has the stronger range — especially on high-card boards — c-betting is a profitable default strategy. But blindly c-betting 100% of the time is a losing strategy against thinking opponents. Modern solver-based play is selective.

When to Skip the C-Bet

Multi-way pots: With three or more players, at least one is likely to have connected with the flop. C-bet far less often and only with real equity.
Boards that crush opponent's range: If the caller's range hits the board harder than yours (e.g., you open from the button and the BB defends, then the flop comes 6-5-4), checking is often better.
Against maniacs: Hyper-aggressive opponents punish c-bets with raises. Checking to induce bluffs can be higher EV than betting.
Deep stacked against calling stations: Fish do not fold, so c-betting as a pure bluff burns money. Size up with value, skip the bluffs.

Sizing Your C-Bets: Small vs. Large

Two valid sizing strategies exist: small & wide (25-33% pot with your entire range on dry boards) and large & polarized (66-100% pot with only strong hands and selected bluffs on wet boards). Small sizing lets you c-bet frequently for cheap information; large sizing charges draws and builds a bigger pot with value hands. Mixing both correctly is the mark of an advanced player.

Range Advantage Matters Most

Before c-betting, ask: whose range hits this flop harder? If you opened from early position and the flop comes A-K-4, your range is loaded with Ax and Kx combos — bet small with everything. If you opened from the cutoff and the flop comes 7-6-5, the BB caller's range connects better — check more often and give up your air. Range advantage trumps hand strength when sizing c-bets.

Note: This calculator provides heuristic-based recommendations. Optimal GTO frequencies depend on exact preflop action, position, and stack depth. Use this as a starting framework and adjust based on table reads.

The auto-pilot c-bet trap and how to escape it

For years, the standard advice was simple: raise preflop, c-bet the flop. Two-thirds pot, almost always, regardless of texture. This was the best advice available in 2008. It is now responsible for more lost money than almost any other habit at low and mid stakes. The reason is that everyone else read the same books, and now everyone is calling those c-bets light.

Modern c-bet strategy is not about what to bet. It is about whether to bet at all, then how much to bet conditional on the texture, your range, and the opponent. Three things, in that order. Most players skip the first question entirely and jump straight to "how much." They c-bet a low connected board with ace-king and look surprised when they get check-raised by a player who flopped two pair.

Board texture is the first variable that should change your sizing. A K-7-2 rainbow flop favors the preflop raiser massively. The big card hits your range hard, the rest are blanks, and there are no draws to charge. Bet small here — 25 to 33 percent pot. You do not need protection, and the small bet keeps your bluffs cheap while still extracting value from worse top pairs. On a J-T-9 two-tone flop, you have lost the range advantage. The caller has more two pair and straights than you do. If you bet at all, bet large to charge draws and to commit yourself, but more often, just check.

Opponent type is the second variable. Against a calling station who clicks "call" with any pair or draw, you want to bet larger when you have a hand and skip the bluffs entirely. Against a tight player who folds top pair to a half-pot bet, smaller sizings work because you are not trying to fold out anything strong — you are picking up the dead money from their air. Against a maniac, check-call or check-raise becomes more profitable than betting because you let them barrel into you with worse.

Multiway pots are where the auto-pilot c-bet completely breaks. With three or four players in the pot, someone has hit the flop. You can no longer fire blindly into a wall of opponents. Frequencies drop to roughly 30%, sizes go up when you do bet, and your bluffs need to have backup equity (overcards, gutshots, backdoor flush draws) to survive being called by one player and raised by another.

The calculator above takes those variables and gives you a starting point. It is not GTO. It is not perfect. But it forces you to think about texture, range advantage, and opponent type before you make the bet, which is the actual skill. A correct check is worth more than a perfectly sized incorrect bet. Once you internalize that, your c-bet frequency drops, your win rate goes up, and the players who used to check-raise you start checking back to you instead.

C-Bet Sizing questions

What is a good c-bet size in poker?

A good default c-bet size is 25-33% pot on dry flops, 50-66% pot on medium flops, and 66-100% pot on wet boards. The size should change when your range advantage, board texture, and opponent type change.

When should you make a small continuation bet?

Small c-bets work best on dry boards where the preflop raiser has a clear range advantage, such as K-7-2 rainbow. The small size lets value hands get called by worse pairs and keeps bluffs cheap.

When should you avoid c-betting?

Avoid c-betting when the board hits the caller much harder than your range, when the pot is multiway, or when a calling station is unlikely to fold. Checking protects your range and avoids burning money with weak bluffs.

How does board texture change c-bet sizing?

Dry boards usually need smaller bets because there are few draws to charge. Wet boards need larger bets with value hands because straight and flush draws can call profitably if you give them a cheap price.
