What Is the Trapezoid Rule in Ice Hockey?

What is the trapezoid behind the net, and how does it limit goaltender puck handling?

Editor: Coach Mark • Updated: February 25, 2026

Short Answer

The trapezoid rule limits where a goaltender can play the puck behind the goal line. Goalies may only handle the puck inside the trapezoid-shaped area behind the net.

Full Explanation

Behind each net, two diagonal lines form a trapezoid shape extending from the goal line to the end boards. This marked area defines where a goaltender is allowed to play the puck.

If a goalie handles the puck outside the trapezoid and behind the goal line, it results in a minor penalty for delay of game.

The rule was introduced to reduce excessive goalie puck-handling and encourage more forechecking pressure and offensive play.

Goalies may still play the puck freely in front of the goal line and within the trapezoid behind it.

Why the Trapezoid Rule Exists

Before this rule, elite puck-handling goalies could eliminate dump-ins and slow the game. The trapezoid increases forechecking opportunities and keeps offensive pressure more dynamic.

Key Takeaways

  • The trapezoid is located behind the net.
  • Goalies may handle the puck only inside this area behind the goal line.
  • Playing the puck outside the trapezoid can result in a penalty.
  • The rule promotes faster, more aggressive forechecking.
