How do I make a poker tournament bracket for eleven people?

How to use this answer

This answer is based on the mathematical principle or published rule identified in the source below. If the question involves a live betting market, confirm its settlement definition before applying it to a specific bet.

Use a single-table or two-table seating chart and a timed blind schedule; poker tournaments normally use chip-based elimination, not a knockout bracket.

Buy equipment for the actual table size, number of players and storage needs. For a one-off casual game, adaptable accessories can be more useful than a large permanent poker table.
