How long does a high school basketball game usually last?

In my experience, the typical high school basketball game usually lasts around 1.5 hours. This includes four quarters, each lasting 8 minutes, along with breaks in between. However, this timeframe can vary depending on factors such as overtime and timeouts. Additionally, halftime breaks can also add extra time to the game's overall duration. It's always a good idea to plan for a little extra time, just in case the game runs longer than expected.
