Poker Blind Structure Calculator

Starting blinds and stack depth

What matters is the ratio of stack to blind, not the raw numbers. Set the opening big blind to about 1% of the starting stack so everyone begins around 100 big blinds deep — a 10,000 stack starts at 50/100, a 5,000 stack at 25/50. Deeper starts of 150–200 big blinds reward post-flop skill but lengthen the game. The generator sets the opening level from your stack automatically, and the chip distribution calculator turns that stack into chips of each colour.

How often should blinds go up?

Once per level, and the level length is the dial that decides how long the night runs:

• 20 minutes is the home-game standard. Deep enough that good players can play poker, short enough to finish in an evening.
• 15 minutes for a weeknight, or any time you need to be done in three hours.
• 10 minutes for a turbo. Expect the last two hours to be mostly preflop decisions.
• 30 minutes or more if the group treats it as the main event. Nine or ten players at 30-minute levels is a five to six hour night.

Never raise blinds mid-level or "when it feels slow" — the whole point of a published schedule is that everyone can see what is coming and plan a stack around it. If the game is running long, add a level of the same length rather than jumping the blinds.

How much should each level raise them?

Roughly 25–50% per level. Gentle 25–33% steps make a slower, more strategic tournament; jumps of 40–50% force the action and shorten the night. The generator picks an increase that lands your tournament near your target duration — the standard four-hour structure below averages 41% a level — then rounds every level to clean numbers so nobody is making change for a 137 big blind. Antes come in from level 4 to grow pots and speed up play.

Where the breaks go

A 10-minute break every four levels is the usual rhythm: it lands about every 80 minutes with 20-minute levels, which is roughly when people want food, a cigarette or the bathroom anyway. Two things make breaks worth planning rather than calling on the fly:

• They are real minutes. Three breaks add half an hour to the night. The estimate on this page counts them, which is why turning breaks off gives you more levels in the same slot.
• They are where the admin happens. Colour up the small chips, close rebuys, and reseat the table at a break, never mid-level.

When to stop rebuys

Cardrooms close late registration at a break so nobody buys in halfway through a level and the chip count is known. Do the same at home: end rebuys at a break in the first third of the tournament. For the standard four-hour structure that is the break after level 4 — 1h 20m in. The calculator prints that cutoff on the schedule, because "can I rebuy?" three hours into a game with two players left is an argument nobody needs.

Rebuys also add chips: a rebuy tournament ends deeper and runs longer than a freezeout with the same field. Tick the rebuy box and the generator plans for the extra chips. Whether the rebuy is a full stack, a half stack, or an add-on everyone can take at the cutoff is your call — write it on the sheet with the blind schedule.

Ready-made structures for 8 players

All four, with a 10,000 starting stack and a 10-minute break every four levels, straight from the generator:

The "finish" column is the last level, and it is the honest measure of how a structure ends: the standard four-hour night finishes with about 27 big blinds in play across the whole table, so the final few hands are short-stacked whatever you do. That is where the push/fold charts and the ICM calculator start to matter.

A printable blind structure template

Hit Print and you get a one-page sheet with the event name, the field and stack, every level with its clock time, the breaks, the rebuy cutoff and a blank finishing order to fill in as players bust. Tape it to the table or the fridge; it is the same information the timer shows, on paper, for the people who want to know when 400/800 arrives. If you would rather work from the default four-hour structure, this is it:

11 levels of 20 minutes plus 2 breaks = 4h 00m. Change the stack and every blind scales with it.

How long will my tournament last?

The arithmetic is levels × level length + breaks, and the structure is built to run out of blinds at about that point. What pushes a real night longer is everything around the cards: a late start, a slow first level while people buy in, rebuys, and a table that talks. Add 20–30 minutes to any estimate for a friendly game.

Want to finish sooner? Shorten the levels, or lower the target duration and let the generator use bigger blind jumps. Both work; shorter levels keep the structure smooth, bigger jumps make the last levels wilder.

Running the night

Once the schedule looks right, hit Start timer for a fullscreen clock that counts every level and break down and shows what is coming next, or send the structure to the tournament clock with one link for entrant tracking, prize-pool totals and a level-change chime. Then it is the money: the payout calculator splits the prize pool, bounty payouts handle a knockout or mystery format, and the chop calculator settles a deal at the end. Rules worth agreeing before the first hand are in poker rulings, and the house rules generator prints them on a sheet to pin up next to this one. There is a full checklist in how to host a poker night.
