Poker Range Calculator (Range vs Range Equity)

Compare a hand against a range, or range against range, on any board. Paint the 13×13 grid, use percentage presets, or type standard notation such as 22+, ATs+, KQo.

How to use the range calculator

  1. Pick a mode for each seat: Hand for specific cards, Range for a grid, Random for an unknown player.
  2. Paint the grid by clicking or dragging. Pairs run down the diagonal, suited hands sit above it and offsuit hands below it. The counter shows how many of the 1,326 combinations you selected.
  3. Use the Top X% presets for quick opening ranges, or type a range in the text box and press Tab.
  4. Add a board and dead cards. The equity of each seat updates after a short simulation.

Reading range equity

Equity against a range tells you how a hand performs on average across everything an opponent could hold. Preflop, A♠K♠ has about 51% against a tight 3-betting range of 22+, AJs+, KQs, AQo+ and roughly 65% against a random hand. Postflop, the same idea shows how the board texture changes things: on A♦7♣2♠ the same AK jumps above 80% against that range because most of it is now dominated.

For bluff-catching, compare your hand with the range an opponent bets with on the river; if your equity is above the pot odds requirement, the call is correct. For range advantage, compare your whole preflop range with the caller’s on a given flop: the side with more equity can usually bet more often and larger. And to study charts, load an opening range from the preflop charts and see how a 3-bet range fares against it.

Frequently asked questions

How is the top X% of hands defined?
Hands are ordered by their heads-up equity against a random hand, computed with this engine, and the preset adds hands from the top until X% of the 1,326 combinations are covered. Other tools use slightly different orderings, so the exact border hands may differ.
What notation does the text box accept?
Pairs (22+, 77-TT), suited and offsuit hands with a plus (A2s+, KTo+), ranges of connectors (T9s-54s), and generic hands without a suffix (AK means both suited and offsuit). Separate entries with commas.
Why is the result Monte Carlo and not exact?
A 20% range holds about 265 combinations; range against range with a full run-out is hundreds of millions of scenarios. The calculator samples 150,000 random deals and reports the margin of error; use More precision to sample 750,000.
Are card removal effects included?
Yes. Combinations that conflict with the board, dead cards or a known hand are removed from each range before sampling, so blockers are accounted for.
