A standard professional basketball game consists of 48 minutes of playing time, divided into four quarters of 12 minutes each.
For college basketball, the game is typically 40 minutes long, with two 20-minute halves.
If you’re referring to other variations (like high school or international play), the length of the game can vary, but the most common formats are 48 minutes for NBA and 40 minutes for NCAA. Keep in mind, the game clock stops for various reasons like fouls, timeouts, or when the ball goes out of bounds, so the actual duration of a game is longer than just the playing time.
