In association football (soccer), each team has 11 players on the field at any given time, including one goalkeeper and 10 outfield players. This means there are 22 players total on the field during a standard match, with each team arranged in various formations of defenders, midfielders, and forwards depending on tactics

. In American football, each team also fields 11 players on the field at a time, but these are divided into offense and defense units. So during play, there are 22 players on the field total—11 offensive players and 11 defensive players. Teams have larger rosters (e.g., 53 players in the NFL), but only 11 per side are on the field at once

. To summarize:

Football Type| Players per Team on Field| Total Players on Field
---|---|---
Association Football| 11 (1 goalkeeper + 10 outfield)| 22
American Football| 11 (offense) / 11 (defense)| 22

Thus, in both main types of football, 11 players per team are on the field during play, totaling 22 players on the field at once.
