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.
