How Long Is an Ice Hockey Game? Full Breakdown

By Sarah Miller · December 11, 2038

An ice hockey game typically lasts 60 minutes of regulation play, divided into three 20-minute periods, with intermissions between each. However, the total duration including stoppages, intermissions, and potential overtime can range from 2.5 to over 3 hours.

Understanding the Structure of an Ice Hockey Game

The standard length of a professional ice hockey game is built around three periods of 20 minutes each, totaling 60 minutes of regulation time. The clock stops whenever play is halted—such as after goals, penalties, or puck out of bounds—which significantly extends the actual time spent at the arena.

Key Time Elements in a Hockey Game

Regulation Time: Three 20-minute periods with 15-17 minute intermissions.
Clock Stoppage: Frequent during play, increasing real-time duration.
Overtime: Used in playoff or tied regular-season games.
Shootout: Follows overtime if the game remains tied.
TV Timeouts: Especially in NHL, commercial breaks add to game length.

NHL Game Duration vs. Other Leagues

While the NHL follows a standardized timing format, other leagues such as international tournaments, college hockey, and youth leagues may differ in period length and overtime rules.

League/Organization	Period Length	Number of Periods	Overtime Format (Regular Season)	Average Total Game Time
NHL (National Hockey League)	20 minutes	3	5-minute 3-on-3 sudden death	2 hours 40 minutes
NCAA Men's Hockey	20 minutes	3	5-minute 5-on-5, then shootout	2 hours 25 minutes
IIHF (International Ice Hockey Federation)	20 minutes	3	10-minute sudden death, then shootout	2 hours 30 minutes
USA Hockey (Youth, 12U)	15 minutes	3	No OT in most cases	1 hour 30 minutes
Professional Women's Hockey League (PWHL)	20 minutes	3	3-on-3 for 10 minutes, then shootout	2 hours 35 minutes

The data shows that while regulation time is consistent across top-tier leagues, the inclusion of overtime formats and broadcast requirements increases average game duration. NHL games are among the longest due to commercial timeouts and structured intermissions. Youth games are shorter both in period length and overall structure to accommodate younger athletes.

Overtime and Shootout Rules by Competition

When a game ends in a tie during the regular season, different leagues apply distinct overtime procedures to determine a winner.

NHL Overtime Format

In the NHL regular season, a 5-minute sudden-death overtime is played with 3-on-3 skaters. If no goal is scored, a shootout decides the winner. In playoffs, however, full 20-minute periods continue until a goal is scored.

International and Collegiate Variations

IIHF: 10-minute 3-on-3 overtime followed by a shootout.
NCAA: Five-minute 5-on-5 overtime; if tied, a shootout follows.
PWHL: Ten-minute 3-on-3 overtime, then shootout if needed.

Factors That Extend Game Duration

Beyond the 60 minutes of regulation, several elements contribute to the extended real-time length of a hockey game.

Common Time Extensions

Intermissions: 17 minutes between periods in the NHL.
Penalties: Power plays often lead to strategic stoppages and delayed resumptions.
Video Reviews: Goals and offside calls are reviewed, adding delays.
Injury Timeouts: Medical staff entering the ice pauses the clock.
Commercial Breaks: Broadcasted games include scheduled ad breaks.

Do women's professional hockey games last the same as men's?

Yes, PWHL games follow the same 60-minute regulation format with three 20-minute periods. Overtime rules are similar but feature a longer 10-minute 3-on-3 period compared to the NHL’s 5-minute version.
