The small blind and big blind are two forced bets posted before the cards are dealt. The player just left of the dealer button posts the small blind; the next player left posts the big blind, usually double the small blind. These bets seed the pot and guarantee there’s always something to fight for on every hand.
Why the blinds exist
Without forced bets, the correct strategy would be to fold everything and wait for aces. Nobody would ever put money in, and there’d be no pot to win. The blinds fix that by creating a small pot every single hand, giving players a reason to enter with a range of hands instead of only premiums. In this sense the blinds are the engine that makes poker a game rather than a staring contest.
Who posts each blind
The blinds are tied to the dealer button, which rotates one seat clockwise after every hand:
- Small blind (SB): the seat immediately clockwise (left) of the button.
- Big blind (BB): the seat immediately clockwise (left) of the small blind.
Because the button moves each hand, every player passes through both blinds over a full orbit. Nobody escapes paying — that’s what keeps the game fair. For the full mechanics of the rotating button, see how the dealer button works.
How much each blind is
The big blind is normally twice the small blind, and the pair of numbers names the stakes:
| Stakes | Small blind | Big blind | Minimum raise (to) |
|---|---|---|---|
| $1/$2 | $1 | $2 | $4 |
| $2/$5 | $2 | $5 | $10 |
| $5/$10 | $5 | $10 | $20 |
The big blind also sets the table’s minimum bet. A standard opening raise is at least double the big blind, so at $1/$2 the smallest legal raise is to $4.
The order of action pre-flop
Here’s the part that trips up new players: the blinds are forced bets, but they still act in turn. Pre-flop, action starts with the player left of the big blind (under the gun) and moves clockwise. The blinds act last because they already have money in.
- Under the gun acts first, then action moves clockwise.
- The small blind acts second-to-last.
- The big blind acts last pre-flop — the only seat that can simply “check” if nobody raised, because the big blind already covers the current bet.
Does the small blind have to call the big blind?
No — the small blind has all three normal options: fold, call, or raise. The wrinkle is that the small blind already has chips in the pot, so it only needs to add the difference to call. At $1/$2, the small blind has posted $1 and needs just $1 more to call the $2 big blind.
This is why beginners often ask whether the small blind must “match” the big blind. You match the big blind’s total, but you get credit for what you already posted.
Worked example: one hand at $1/$2
Six players, and the button is on seat 6.
- Seat 1 (SB) posts $1. Seat 2 (BB) posts $2. The pot is $3 before any cards.
- Seat 3 (UTG) acts first, raises to $6.
- Seats 4, 5, and the button (6) all fold.
- Seat 1 (small blind) already has $1 in; to call $6 it adds $5. It folds instead.
- Seat 2 (big blind) already has $2 in; to call it adds $4, or it can 3-bet or fold. It calls, adding $4.
Two players see the flop, and the big blind — despite acting last pre-flop — will act first on every street after the flop. That positional flip is exactly why the blinds are the hardest seats to play well.
Post-flop, the blinds act first
Pre-flop the blinds act last; post-flop they act first. After the flop, action starts with the first live player left of the button — usually the small blind, then the big blind. Acting first means you commit chips with the least information, which is why the blinds lose money over time and demand careful, tighter play.

Put it together
The blinds are forced bets that make the game go: the small blind sits left of the button, the big blind sits left of that at double the amount, they act last pre-flop and first post-flop.

Frequently asked
How do the small blind and big blind work?
They are two forced bets posted before any cards are dealt. The player to the left of the dealer button posts the small blind, and the next player to the left posts the big blind, which is usually twice the small blind. These bets start the pot and set the minimum betting amount for the hand.
Who posts the small blind and big blind?
The player immediately clockwise from the dealer button posts the small blind, and the next player clockwise posts the big blind. Because the button moves one seat each hand, everyone takes their turn in both blinds over a full orbit.
Does the small blind have to match the big blind?
Not automatically. The small blind is already partway toward the big blind, so to stay in the small blind only needs to add the difference — for example, adding the other half of a small-blind-sized chip to complete a call. The player can also raise or fold.
Is the big blind bigger than the small blind?
Yes. The big blind is normally double the small blind — for example, $1/$2 means a $1 small blind and a $2 big blind. The big blind amount also names the stakes and sets the table's minimum bet.
