College basketball games typically last about 2 hours, though the exact duration can vary depending on format, stoppages, and overtime. Here are the common formats and what drives the total time:

• NCAA Division I men’s basketball: Games are played in two 20-minute halves. The official playing time is 40 minutes, but with stoppages (timeouts, fouls, media breaks) and potential overtime, most games run around 2 to 2.5 hours.
• NCAA Division I women’s basketball: Games are played in four 10-minute quarters (40 minutes of official playing time). The total game time is often similar to men’s games, typically around 2 hours, and can extend longer if overtime occurs.
• Other factors that extend game length:
  • Overtime periods (each additional 5 minutes in most college contexts)
  • Timeouts and media timeouts
  • Referee and review stoppages
  • Halftime length (generally around 15 minutes)

If you’d like, I can tailor this to a specific league or season (e.g., current NCAA changes, conference variations) and provide approximate average durations with typical ranges.
