Small Blind and Big Blind Amounts and Ratio
How much are the small and big blind? The standard 1:2 ratio explained, plus stakes notation, non-standard ratios, and how the amounts set the pot.

The small blind is almost always half the big blind — a fixed 1:2 ratio that holds across nearly every cash game and tournament. In a 1/2 game the small blind is $1 and the big blind is $2; in 2/5 it’s $2 and $5. Both are forced bets posted before the cards are dealt, and the pair of numbers names the stakes, small blind first.
The standard ratio
The big blind is posted by the player two seats left of the button; the small blind by the player one seat left. By long-standing convention the small blind is half the big blind:
| Stakes | Small blind | Big blind | Ratio |
|---|---|---|---|
| 1/2 | $1 | $2 | 1:2 |
| 2/5 | $2 | $5 | 2:5 |
| 5/10 | $5 | $10 | 1:2 |
| 25/50 | $25 | $50 | 1:2 |
Notice 2/5 is the common exception where the small blind isn’t exactly half — casinos round to convenient chip denominations. It’s close enough that players still treat it as the standard half-and-full structure. Everywhere the chips allow it, the clean 1:2 ratio wins.
Why the amounts matter
The blind amounts do three jobs at once:
- They seed the pot. Without forced bets, everyone could fold free forever. The blinds guarantee there is always money to fight over.
- They set the minimum bet. The big blind is the smallest legal bet and the smallest legal raise increment for the first betting round. A minimum open raise is to twice the big blind.
- They set the stakes scale. “Buy in for 100 big blinds” means very different real money at 1/2 ($200) versus 5/10 ($1,000). The big blind is the unit everything is measured in.
That last point is why strong players think in big blinds, not dollars. A 100bb stack plays the same whether it’s $200 or $2,000. For the seat-by-seat mechanics behind these forced bets, see how the small and big blind work.
What “the chips” look like at the table
New players often ask which chips represent each blind. There are no special “small blind chips” — you post the blind with ordinary chips matching the amount:
| Stakes | Small blind chips | Big blind chips |
|---|---|---|
| 1/2 | one $1 chip | two $1 chips (or one $2) |
| 2/5 | two $1 chips | one $5 chip |
| 5/10 | one $5 chip | two $5 chips (or one $10) |
A small dealer button puck moves around the table to mark position; the blinds themselves are just cash chips slid forward before the deal. Some rooms use blind markers, but the amount is always defined by the stakes, not by a special token.
The half-sized small blind creates a decision
The 1:2 ratio isn’t arbitrary. Because the small blind has already put in half a big blind, it gets a discount to continue when the action folds around unraised. It only needs to add the other half to match the big blind — a move called completing the blind.
Worked example at 1/2:
- Everyone folds to the small blind. There’s the $1 small blind and the $2 big blind in the pot.
- To call, the small blind adds just $1 (the difference), not a full $2.
- That’s why the small blind can profitably continue with a wide range of hands — the price is half off.
If the blinds were equal, that discount would vanish and the small blind would play far tighter. The half-and-full structure is what makes the small blind a live, strategic seat. Dig into that math in does the small blind match the big blind.
Non-standard ratios
A handful of formats bend the rule:
- Equal blinds (for example 100/100 in some home games): removes the completing discount and simplifies the pot, but sacrifices small-blind playability.
- Straddles and antes don’t change the small-to-big ratio — they add extra forced money on top of the two blinds.
- 2/5 and 5/10/25 live games round to chip-friendly numbers, so the small blind may be slightly more or less than exactly half.
None of these replace the default. If you sit down at a random table anywhere in the world, assume the small blind is half the big blind until told otherwise.
Tournaments: same ratio, rising amounts
In tournaments the 1:2 ratio holds while the absolute amounts climb each level to force action:
| Level | Small blind | Big blind |
|---|---|---|
| 1 | 50 | 100 |
| 2 | 100 | 200 |
| 3 | 150 | 300 |
| 4 | 200 | 400 |
Each level roughly doubles the last, but the small blind stays half the big blind throughout. Later levels add antes on top, which speeds the game up without touching the blind ratio itself.
The bottom line
“What’s the small blind and big blind?” has a simple answer: two forced bets, the small one half the size of the big one, named by the stakes with the small blind first. That 1:2 ratio seeds the pot, sets the minimum bet, and hands the small blind its half-price call.

Frequently asked
How much is the small blind compared to the big blind?
The small blind is almost always half the big blind. In a 1/2 game the small blind is $1 and the big blind is $2, a 1:2 ratio. That standard ratio is what nearly every cash game and tournament uses.
What does 1/2 or 2/5 mean in poker?
It names the stakes by listing the two blind amounts, small blind first. 1/2 means a $1 small blind and $2 big blind; 2/5 means a $2 small blind and $5 big blind. The big blind also sets the minimum bet.
Can the small blind and big blind be equal?
Occasionally. A few home games and some tournament formats use equal blinds (for example 100/100). But the 1:2 ratio is the near-universal standard because the half-sized small blind creates the completing-the-blind decision that shapes strategy.
Does the small blind ratio change during a tournament?
The ratio stays 1:2 as blinds go up level by level. What changes is the absolute size and, later, the addition of antes. A 100/200 level simply doubles a 50/100 level while keeping the same half-and-full structure.
