Poker blind structure calculator
Generate or edit exact tournament levels, import a schedule, and include timed breaks.
How this tool works
Generate rounded increasing levels or enter custom small blind, big blind, ante and minute rows, with explicit break rows. Schedule JSON can be imported and exported. Generated ties round upwards; custom big blinds may repeat but never decrease. Every duration must be positive. Duration is a plan, not a prediction of the tournament finishing time.
Everything runs on your device. Inputs are not uploaded. The tournament clock can save its schedule and time locally, with a clear control; other inputs are not saved. Export anything you want to keep before leaving the page. Study tools are for practice between sessions; check your poker provider's rules.
