The number of rounds in a fantasy football draft varies depending on the league settings, but common defaults range from about 14 to 16 rounds in typical redraft leagues. For example, Yahoo! usually has 15 rounds, ESPN 16 rounds, CBS 14 rounds, and NFL.com 15 rounds. This number corresponds roughly to roster size, including starters and bench players. In best ball leagues, the number of rounds can be higher, around 18 rounds, and dynasty leagues often have even more rounds, up to 25-30 depending on roster depth. The draft format is commonly a snake-style draft where the order reverses each round to balance draft order advantage. In summary:

• Standard redraft leagues: Usually 14-16 rounds
• Best ball leagues: Around 18 rounds
• Dynasty leagues: Around 25-30 rounds

These settings ensure enough players to fill starting lineups and benches, adjusting for league type and size.
