Blind Structure Calculator
Build a custom blind schedule for your next live poker tournament in seconds. Free, no signup required.
Quick answer: a good blind structure starts players with 100-200 big blinds, raises blinds every 15-20 minutes for a standard-paced event, and adds a short break every 5-8 levels. Faster formats like turbo and hyper turbo shorten levels to 5-10 minutes and start with a shallower stack, compressing the same overall arc into a much shorter event.

How to Use the Blind Structure Calculator
Building a blind structure by hand means guessing at how fast blinds should climb, when antes should kick in, and how many breaks a session actually needs, get any of that wrong and a tournament either drags on for hours past when it should have finished, or rushes players out before they've had a real chance to play. This tool handles that math for you: set how long you want the tournament to run, pick a pace, and it builds out the full level-by-level schedule, breaks included.
- Set your tournament duration - how many hours you want the event to last.
- Optionally enter your number of players - which helps the calculator pick a sensible number of levels for the size of your field.
- Choose a structure style - that matches the kind of event you're running, standard, deep stack, turbo, or hyper turbo.
- Leave blind level duration on Auto - for a pace matched to your chosen style, or set a custom level length.
- Turn antes on or off - depending on how much extra pressure you want on stacks in the later levels.
- Click Generate structure - and the full level-by-level schedule appears on the right, including scheduled breaks.
A quick note before you run with it: this calculator gives you a solid, sensible starting point, it isn't a certified structure, and no algorithm can perfectly account for how your specific table plays. A good host always reviews the generated blinds, antes, and break schedule first, and adjusts anything that doesn't fit the room.
Understanding Each Setting
Tournament Duration
This is the total playing time you want the event to take, from the first hand to (roughly) the last. Because levels and breaks are whole blocks of time, the actual runtime the calculator produces can land slightly under your target, it will never run over, but it also won't cut a level or a break short just to hit an exact number.
Number of Players
This field is optional, but it isn't just for reference, it changes the result. A bigger field genuinely needs more distinct blind levels to work through realistically, so the calculator builds in a higher minimum level count for larger tournaments. Leave it blank and it assumes a moderate field of 50 players.
Structure Style
Style controls the overall pace and feel of the tournament, how deep stacks start, and how quickly pressure builds:
- Standard - a balanced, steady pace suited to most home games, clubs, and leagues.
- Deep stack - a slower pace with deeper starting stacks, giving players more room to play real poker before blinds start biting.
- Turbo - a faster pace with a shallower starting stack, building pressure earlier for a shorter overall event.
- Hyper turbo - the fastest, highest-variance pace, typically without breaks, for tournaments that need to wrap up quickly.
Blind Level Duration
This is how long each blind level lasts on the clock. On Auto, the calculator picks a level length that matches your chosen structure style. Switching to Custom lets you set your own level length between 5 and 60 minutes — shorter levels mean more frequent blind increases and a faster-moving tournament overall.
Antes
An ante is a forced contribution every player puts in before the hand starts, on top of the blinds — it keeps pots growing and discourages players from folding their way through a tournament. When enabled, antes phase in partway through the tournament rather than from the very first level, matching how most real tournaments introduce them.
Example Blind Structure
A worked example using the Standard style for a 9-player, 2-hour home game, so you can see exactly what the calculator produces before you run your own numbers. Starting stack: 1,500 (150 big blinds).
| Level | Small Blind | Big Blind | Ante | Duration |
|---|---|---|---|---|
| 1 | 5 | 10 | — | 15m |
| 2 | 10 | 20 | — | 15m |
| 3 | 15 | 30 | — | 15m |
| 4 | 20 | 40 | — | 15m |
| 5 | 30 | 60 | 60 | 15m |
| 6 | 40 | 80 | 80 | 15m |
| Break | 10m | |||
| 7 | 65 | 130 | 130 | 15m |
| 8 | 100 | 200 | 200 | 15m |
8 levels, 1 break, total runtime 2h10m (the 9-player floor on level count pushed this slightly past the 2h target, see "How We Build Your Structure" below for why).
How We Build Your Structure
The calculator simulates the actual level-and-break sequence against your time budget in one pass, rather than estimating level count and break count separately - that's what keeps the total runtime from drifting away from what you asked for. Blinds increase by a fixed rate each level (a faster rate once the tournament reaches its later stages), rounded to clean chip denominations that match your chosen style's chip set.
Player count sets a floor on how many levels a field that size realistically needs to reach a natural final table - for smaller fields, this floor can occasionally push the total runtime slightly past your requested duration, exactly as it did in the example above. A safety cap, grounded in the total chips in play, also prevents blinds from compounding into unrealistic values on very long, many-level configurations.
Frequently Asked Questions
What is a good starting stack for a home poker tournament?
Most home tournaments start players with somewhere between 100 and 200 big blinds. That's deep enough to allow real post-flop play in the early levels, without making the tournament drag on forever. Deep stack formats often start even deeper, around 200 big blinds, while turbo formats start shallower, closer to 75-100 big blinds, since the whole event is designed to move faster.
How long should each blind level be?
For a standard-paced home game or club tournament, 15-20 minute levels are typical. Shorter levels (5-10 minutes) suit turbo and hyper turbo formats where the goal is a fast, high-variance event. Longer levels (20-30 minutes) suit deep stack tournaments where players want more room to play real poker before the blinds start pressuring stacks.
When should antes start in a tournament?
Antes are usually introduced partway through an event, not from the very first hand, commonly somewhere around the midpoint, once blinds alone aren't creating enough pressure on stacks. In tournaments with a lot of players, antes often start a bit earlier relative to the total number of levels, since a bigger field needs pressure building sooner to keep the tournament moving toward a reasonable length.
What's the difference between turbo and standard structures?
A standard structure increases blinds at a moderate, steady pace, giving players time to make decisions and build up a hand history. A turbo structure raises blinds faster and starts players with a shallower stack, compressing the whole tournament into a shorter, higher-pressure event. Hyper turbo goes further still, often skipping breaks entirely, for tournaments that need to finish in an hour or two.
How many players can this calculator handle?
The calculator supports anywhere from 2 to 200 players. Entering a player count is optional, but it does affect the result: a larger field needs more distinct blind levels to reach a realistic final stage without rushing, so the tool builds in extra levels for bigger tournaments. If you leave the field blank, it assumes a moderate field of 50 players.
How many blind levels does a typical poker tournament have?
Most tournaments run somewhere between 15 and 30 blind levels from start to a realistic final table, though the exact count depends heavily on level length and field size. Bigger fields need more levels to reach a natural conclusion without rushing, while shorter, faster formats like turbo and hyper turbo compress the same overall arc into fewer levels.
How long does a poker tournament usually take to finish?
For a standard-paced home game or club tournament, plan on somewhere between 3 and 6 hours depending on field size - bigger fields simply take longer to work down to a winner. Turbo formats can wrap up in under 2 hours, while deep stack events regularly run 6+ hours because of the slower blind increases.
What's a good break schedule for a poker tournament?
A common approach is a short break every 5-8 levels, long enough for players to reset (usually 10 minutes) without stalling momentum. Very short formats like hyper turbo typically skip breaks entirely since the whole event is designed to move fast, while longer tournaments need more frequent breaks simply because players are at the table for so many hours.
Do I need special software to run this structure live?
You can run any generated structure with a phone timer or a whiteboard, but most hosts running anything beyond a casual home game use a dedicated tournament clock so blinds, antes, and breaks advance automatically and everyone can see the current level. That's exactly what BlindShark's built-in clock does, alongside player and table management for the rest of the event.
