Poker Tournament Blind Schedule

A tournament blind structure controls how fast the game escalates. The key trade-off:

• Slow structure = more poker, more skill expression, longer total duration
• Fast structure = more variance, more all-ins, shorter game

What the structure depends on:

1. Starting stack (chips), typically 1,000-20,000
2. Number of players, because stack × players is the total pool of chips and that pool is what the blinds eventually eat
3. Target tournament duration (hours)

The fundamental rule: A well-paced tournament should give players roughly 75-150 big blinds at the start and slowly compress that to 10-20 BBs by the final table.

The part every home-game structure gets wrong

Blinds grow geometrically and chips do not grow at all. That sounds obvious written down, and it is still the reason most homemade structures fall apart.

Take a 9-player game, 5,000 chips each, blinds starting at 25/50 and going up 1.5× every 20 minutes. Five hours is fifteen levels, and by level 15 the big blind is north of 14,000. There are only 45,000 chips on the table. Three big blinds exist in the entire tournament, split between whoever is left.

The escalation has to stop somewhere, and the place it stops is set by the chips in play, not by the clock. Total chips is players × starting stack, and it never changes. When the last two players are heads-up you want them to have something to play with, so aim for the final big blind to be around 1/25th of all the chips in play. That leaves the finalists roughly a dozen big blinds each: short, decisive, and still poker.

Work backwards from there and the structure designs itself. The number of levels you can support is fixed by how far the blinds have to travel, and the level length is then just the duration divided by that. Choose the level length first, as most people do, and you are really choosing how long the tournament runs, whatever you wrote on the invitation.

Standard blind progression formula: Each level multiplies blinds by ~1.4-1.7×. Common pattern:

• Level 1: 25/50
• Level 2: 50/100
• Level 3: 75/150
• Level 4: 100/200
• Level 5: 150/300
• Level 6: 200/400
• Level 7: 300/600
• Level 8: 400/800
• Level 9: 600/1,200
• Level 10: 800/1,600
• … continues doubling/scaling

Level duration guidelines:

• Quick home game (3-4 hours): 15-min levels
• Standard home tournament (4-6 hours): 20-min levels
• Series final or deep stack: 30-60 min levels
• WSOP-style major: 60-90 min levels

Those are the lengths people reach for. Whether the one you pick actually produces the duration you want depends on how far your blinds have to travel, which is the calculation above.

Practical adjustments:

• Add antes from level 4-5 onward to drive action
• “Color up” small chips around level 5-6 (remove the smallest denomination)
• Schedule a 10-min break every 90-120 minutes
• Late registration usually closes after level 4-6

The “M ratio” check: A player’s M = Stack / (Sum of Blinds + Antes per orbit). Keep average M above 10 for skill-driven play, above 20 for deep-stack feel.
