A standard hockey game has 60 minutes of game time, but in real life you should plan for about 2.5 to 3 hours from puck drop to final horn.

How long is a hockey game?

  • Regulation hockey: 3 periods of 20 minutes each, for 60 minutes of actual game clock time.
  • With stoppages, intermissions, and TV timeouts, most pro games (like the NHL) run about 2 hours 15 minutes to 3 hours in real time.
  • Intermissions between the 1st and 2nd, and 2nd and 3rd periods are usually around 15–18 minutes each in top leagues.

So if you’re heading to an NHL game, blocking off a solid 3-hour window is a safe bet.

What can make it longer?

  • Overtime: Regular-season NHL games tied after 60 minutes go to a 5‑minute sudden‑death overtime, and then possibly a shootout, adding roughly 10–15 minutes total.
  • Playoffs: Tied playoff games play full 20‑minute sudden‑death overtime periods 5‑on‑5 until someone scores, so games can stretch far beyond 3 hours.
  • Extra stoppages: Penalties, injuries, video reviews, and frequent whistles slow the game and extend real‑time duration.

There have even been historic marathons in the playoffs with multiple overtimes and more than 170 minutes of play, lasting many hours.

TL;DR: The clock says 60 minutes, but if you’re asking “how long is a hockey game” for planning your night, assume around 2.5 to 3 hours, and possibly more if there’s playoff overtime drama.
