# Blind Structure Calculator

The blind structure (or schedule) is one of the most important details of running a successful tournament. Gradual increases of the blinds at each level and finishing on time are characteristics of a good blind structure.

To calculate a blind structure, the minimum information you need is the number of players, target duration, and the starting blind level (which is usually the smallest chip denomination you have). It is also necessary to know how many chips there will be in play and how many rounds there will be. The blind calculator tool below can take care of that and help set up your perfect structure.

To calculate a blind structure, you need the starting blind level, the estimated total value of the tournament chips in play (initial buy-ins plus rebuys and add-ons) and the desired length of the tournament. Use the tool below to help set up your perfect structure.

# Tournament Blind Structure Theory

This section discusses some tournament blind structure theory, which explains why the PokerSoup.com tournament blind structure calculator suggests blind levels the way it does and what you can change to create the right blind structure for your game.

### Starting Number of Blinds

Most tournaments start with 50-100 big blinds. Anything around 200 big blinds is considered a "deep stack" tournament. Deep stack tournaments are considered to be full of skillful poker play and not just pushing your money all in before the flop. The latter occurs quickly in tournaments that start with less than 50 big blinds, which are also aptly nick-named "luck-fests". There just aren't enough chips to maneuver and play real poker.

If all other variables are held constant, starting a tournament with larger chip stacks will increase the length of the game.

The number of rebuys and add-ons in a tournament also effect the total number of chips in play during a tournament. If no other changes are made, more rebuys and add-ons make for a longer tournament.

### Blind Level Round Length

Most live tournaments employ blind level lengths of 15, 20, 30, 45, or 60 minutes. The blind calculator can calculate blinds for any of these blind levels. With a set tournament length, longer blind levels result in less number of rounds and shorter blind levels result in more rounds.
