What it measures
Bet size is the average size of a player’s bets on the flop, turn or river, written as a percent of the pot before each bet. A player who bets 3 into 6 and later 6 into 6 has an average of 75%.
It counts every bet: c-bets, donk bets, probes, stabs and bets in limped pots, as long as it’s the first bet on the street. Raises and check-raises are left out; they have their own raise size stat, measured as a multiple of the bet instead of a share of the pot.
The average answers “how big does this player bet?”, the starting point for every sizing tell. It doesn’t say how they mix sizes. A player who always bets 55% and one who alternates between 30% and 80% can show the same number, and they’re very different opponents. That’s why the HUD also keeps small-bet share and overbet share, the share of their bets under 40% and over 110% of the pot. For c-bets alone, see c-bet size.
How it’s calculated
Each bet a player makes on a street adds one sample: the chips they put in with that bet, divided by everything in the middle before it, times 100. The stat is the average of those samples, kept separately for the flop, turn and river.
- The pot includes earlier streets and dead money, such as a folded small blind.
- Only bets, the first chips put in on a street. Raises are excluded, so a player who mostly check-raises may have few samples.
- Every bet weighs the same: a 2 big blind flop bet and a 40 big blind river bet each add one sample, whatever the pot.
- Each street keeps a single average; nothing is split by position or pot type.
Example: Jun’s flop bets this session were 3 into 6 (50%), 2 into 6 (33.3%), 6 into 6 (100%) and 4 into 10 (40%). Her flop bet size is (50 + 33.3 + 100 + 40) ÷ 4 = 55.8%, shown as 56. Averages hide mixtures: nine bets of 33% and one shove of 200% average (9 × 33 + 200) ÷ 10 = 49.7%, a “half-pot” player who never once bet half pot.
Why it matters
Size tells you about range. In theory big bets are polarized, strong hands and bluffs with little in between, and small bets go with wide ranges, often the whole range on boards that favor the bettor. A player whose flop average sits around 30% is probably betting a lot of hands cheaply; one who averages 90% is betting fewer hands and wants folds or big calls.
In home games the stronger tell is how size changes with hand strength. Many players bet bigger when they’re strong and smaller when they’re unsure, and some do the reverse, small with the nuts to “keep you in”. The average is the baseline you compare each bet against, and the badge shows it on the c-bettor right after they bet, so you see at once whether this bet is bigger or smaller than usual.
It also changes your defense. Against a big bettor you need more equity to call (33.3% against pot) but face fewer bets; against a small bettor you need less (19.9% against 33%) and should continue with more hands. The pages on fold vs small bets and fold vs large bets show how the price moves with size.
Too low, about right, too high
The HUD shows bet size with no typical range and no color: good sizes depend on the board, the stacks and the plan. The bands below are our own, borrowed from the HUD’s size buckets (small under 40%, large from 80%), and they describe styles rather than mistakes.
Small: under 40%
What it says
This player bets small as a habit. On the flop that can be a sound range-betting strategy: a third of the pot with every hand on dry boards. On the turn and river an average this low usually means block bets, “feeler” bets and thin value, the sizes of a player who wants the next card or showdown cheaply. If their small-bet share is high too, the average isn’t hiding a few big bets.
How to exploit it
- Continue wider. Against a 33% bet you need 19.9% equity, so call with gutshots, backdoor draws and any pair.
- Raise their small bets with strong hands and good draws, especially on the turn and river, where small bets are often capped. A raise to three times a 33% bet asks them for far more than they meant to invest.
- Float in position. Small bettors often give up on the next street; take the pot when they check.
- When they suddenly bet big, give it weight: an out-of-pattern size from a small bettor is usually strength.
Medium: 40–80%
What it says
The common middle: half-pot to three-quarter-pot bets. The average alone can’t tell you whether they bet a steady 60% or mix small and big bets that happen to average out, so look at small-bet share and overbet share before reading much into it. A steady medium bettor is easy to play against; a mixer may be balanced, or may be sizing by hand strength.
How to exploit it
- Watch for the deviation. The badge shows their average on the c-bettor after betting; a bet 30 or more points away from it is worth noting.
- Track which way it goes at showdown. If their big bets have shown strong hands twice, fold one pair to them next time; if a big bet showed a bluff, call down.
- Default defense: against 50–75% bets, continue roughly 57–67% of the time heads-up (the minimum defense at those sizes), then adjust with their fold and showdown stats.
Big: over 80%
What it says
They bet pot or more on average. In theory big sizes suit polarized ranges and boards where the bettor holds the strongest hands. In home games an average this high usually means a player who bets big when they have something and checks when they don’t, or one who uses big bets to push people off draws. Both keep their betting range stronger than average. An average over 80% with frequent overbets is a player who goes big on purpose.
How to exploit it
- Fold more marginal hands. Against a pot-sized bet you need 33.3% equity, and their betting range is usually strong.
- Don’t chase weak draws. A gutshot against a pot bet doesn’t get the price.
- Skip light bluff-raises. A player who only bets big when strong rarely folds to a raise.
- Check strong hands to them and check-raise or check-call; big bettors put more chips in for you to win.
- If they also bet often (a high bet when checked to), they’re bluffing big too: call down with your better pairs.
On the flop, turn and river
Flop: bet size
Flop bets are mostly c-bets, so the flop average sits closest to a player’s c-bet habit. A low flop average often means range betting, a third of the pot on dry boards. A high one usually means a player who bets only when they connect, and bets big when they do.
Home-game flops add a twist: bets in big blinds rather than pot fractions. A player who always bets 5 big blinds shows 91% into a 5.5 big blind single-raised pot (5 ÷ 5.5) and 25% into a 20 big blind 3-bet pot (5 ÷ 20). Their flop average then mostly reflects which pots they play, not a sizing plan.
Flop exploit: if their flop average is under 40%, defend wide and raise their small bets with draws; if it’s over 80%, continue with pairs and good draws only, and attack the flops they check.
Turn: bet size
Turn sizes tend to grow as ranges narrow. Many players who bet a third on the flop bet two-thirds or pot on the turn with strong hands and draws, and check the rest. A turn average above the flop average is normal; one below it often means the player shrinks bets when unsure, using a small turn bet to keep control of the pot.
The chips grow too: after a called 66% flop bet, a 66% turn bet costs 2.32 times as much as the flop bet did, because the pot has grown by that factor (1 + 2 × 0.66). The turn is where ignoring a sizing tell starts to cost real money.
Turn exploit: against a player whose turn bets are much smaller than their flop bets, raise the small turn bet with strong draws and two pair or better; it’s often a weak made hand that can’t continue.
River: bet size
River size is the most revealing. With no draws left, the bettor wants either a call from worse or a fold from better, and many players size those two goals differently. In home games big river bets lean toward strong hands for a lot of players, and small river bets are often thin value or a blocker bet from a hand that wants to see showdown.
The river average also sets the price you get as a caller: 25% equity against half pot, 33.3% against pot, 40% against twice the pot. A player who averages 100% or more on the river makes you pay the most for every bluff-catch.
River exploit: against a player whose river average is under 40%, raise their small river bets with strong hands and the occasional bluff that blocks their value. Against one whose average is over 100%, fold your weakest bluff-catchers unless their river bluff (shown) says otherwise.
When it’s your own number
No read is written about your bet size, but anyone watching your badge after you c-bet sees it. If your average is very small, observant players continue wider and raise you; if it’s very big, they fold marginal hands and check-raise your bets with their strong ones.
The real risk is a size that tracks your hand. If you bet 75% with top pair and 33% with draws, a player who notices will fold to your big bets and raise your small ones. Pick sizes by board and street, not by hand strength, and use the same size with value hands and bluffs in each spot. Your small-bet share and overbet share show whether you actually mix.
Using it on the HUD
Bet size shows on the badge of the c-bettor after they bet: when you face a c-bet, you see that player’s average bet size for the street next to the bet they just made. It has no typical range and no color, it’s faded when fewer than 12 bets stand behind it, and every street’s value is on the player database page.
An average settles faster than a percentage when a player sizes consistently, but a single shove can drag a short sample far off, as the example above shows. Treat 12–20 bets as a first impression and 30 or more as a usable baseline. Read it with small-bet share, overbet share and their c-bet frequency for the same street.
Questions
What is a normal bet size in poker?
There isn’t one. Common sizes run from about a third of the pot to the full pot, and the right one depends on the board, the stacks and the plan, which is why the HUD shows bet size without a typical range. As a rough guide, averages under 40% suggest range betting or block bets, 40–80% is the middle, and over 80% is a big, polarized bettor.
What does a big bet size mean in poker?
In theory a big bet represents a polarized range: strong hands and bluffs, few medium hands. In home games it more often means strength, because many players bet bigger when they like their hand. Compare the bet with the player’s average on the HUD: a bet well above their usual size is out of pattern, and that is the tell to act on.
Does bet size include raises?
No. Bet size averages only bets, the first chips put in on a street, as a percent of the pot before them. Raises and check-raises are tracked in raise size instead, as a multiple of the bet they raised. C-bets are included in bet size and also have their own c-bet size stat.
How many bets do you need before bet size is reliable?
About 30 bets per street for a usable baseline, with 12 as the bare minimum: below 12 the HUD fades the number. A player with consistent sizes settles faster; a player who mixes small bets and shoves needs more, because one big bet moves a short average a lot. Check small-bet share and overbet share to see the mix.
