Poker Odds Chart: The Numbers to Memorize

A poker odds chart turns memory into instant recall: instead of computing fractions at the table, you glance at a number you already know. This page collects the three charts that matter most — outs to percentages, common drawing odds, and preflop matchups — with the exact figures verified against the math. Learn the handful of rows you meet most and you’ll price nearly every decision on sight.

Outs to percentage chart

This is the master table. For each out count, it shows your chance of improving on one card (turn or river) and across both cards from the flop. The rule-of-4-and-2 estimate is included so you can see how close the shortcut is.

Outs	1 card (%)	2 cards (%)	Rule ×2 / ×4	Example draw
2	4.3%	8.4%	4 / 8	Pocket pair → set
4	8.7%	16.5%	8 / 16	Gutshot
5	10.9%	20.3%	10 / 20	Gutshot + overcard
6	13.0%	24.1%	12 / 24	Two overcards
8	17.4%	31.5%	16 / 32	Open-ended straight
9	19.6%	35.0%	18 / 36	Flush draw
12	26.1%	45.0%	24 / 48	Flush + gutshot
15	32.6%	54.1%	30 / 60	Flush + open-ended
21	45.7%	70.0%	42 / 84	Wrap draws

Notice the rule of 4 and 2 tracks the true numbers well up to about nine outs, then starts over-counting on the two-card column (60% estimated vs 54% real at 15 outs). For big draws, trim the flop estimate by a few points. The full logic is in the rule of 4 and 2, and how to count the outs in the first place is in counting poker outs.

Common drawing odds

The same information framed the way it comes up in hands — as ratios and the exact percentage, which you compare directly to your pot odds.

Situation	Odds against	Percentage
Flopping a set with a pocket pair	7.5-to-1	~11.8%
Completing a flush draw by the river (from flop)	1.9-to-1	~35%
Completing an open-ended straight by the river	2.2-to-1	~31.5%
Hitting a gutshot by the river	5.1-to-1	~16.5%
Flush draw hitting on the turn only	4.1-to-1	~19.6%
Pairing an unpaired hole card by the river	~2.5-to-1	~28%
Flopping a flush draw with two suited cards	~8-to-1	~10.9%

Preflop matchup chart

When chips go in before the flop, these matchups recur constantly. Percentages are all-in equity for the two hands running to the river.

Matchup	Example	Favorite equity
Pair vs two lower cards	88 vs 76	~83%
Pair vs one over, one under	99 vs A8	~71%
Pair vs two overcards (coin flip)	66 vs AK	~55%
Dominated hand	AK vs AQ	~74%
Higher pair vs lower pair	QQ vs 99	~82%
Two overcards vs two lower cards	AK vs QJ	~63%

The classic “coin flip” — a pocket pair against two higher cards — is really about 55/45 in the pair’s favor, not a true 50/50. Small edges like that decide tournaments.

Worked example: reading the chart mid-hand

You hold J♠ T♠ on 9♠ 8♦ 2♠. You have a flush draw and an open-ended straight draw.

• Count outs: 9 spades + 8 straight cards (any 7 or Q) − 2 spades already in the straight count (7♠, Q♠) = 15 outs.
• Look up 15 outs: the chart says ~54% by the river, ~32.6% on the next card alone.
• Price the call: opponent bets $30 into a $60 pot. You call $30 into a $120 pot → 30 / 120 = 25%.
• Decide: even your single-card equity (32.6%) beats the 25% price, so calling is clearly profitable — and raising is worth considering with a draw this strong.

How to actually use a chart

Charts are training wheels. In real play you won’t scan a table — you’ll recall the row. The path is: read the chart, count outs at the table, notice the recall arriving faster each session, then drop the chart entirely. The three numbers to burn in first are 9 outs = 35%, 8 outs = 31.5%, and 15 outs = 54%.

The takeaway

A poker odds chart is a memory aid, not a crutch. Learn the outs-to-percentage rows you meet most, the handful of drawing odds, and the recurring preflop matchups, then compare them to your price. Build the rest of your foundation in the poker odds & math hub and practice inside Texas Hold’em.
