Lines The
centre line divides the ice in half crosswise. It is used to judge
icing. It is a thick line, and in the NHL must "contain regular interval markings of a uniform distinctive design, which will readily distinguish it from the two blue lines" (i.e. it must not be a solid single colour as the blue lines are). It may also be used to judge
two-line pass violations in leagues that use such a rule. There are two thick
blue lines that divide the rink into three parts, called
zones. The blue lines are used to judge if a player is
offside. If an attacking player crosses the line into the other team's zone before the puck does, they are said to be offside. Near each end of the rink, there is a thin red
goal line spanning the width of the ice. It is used to judge
goals and icing calls.
Faceoff spots and circles There are 9
faceoff spots on a hockey rink. All
faceoffs take place at these spots. There are two spots in each team's defensive zone, two at each end of the neutral zone, and one in the centre of the rink. There are
faceoff circles around the centre ice and end zone faceoff spots. There are hash marks painted on the ice near the end zone faceoff spots. The circles and hash marks show where players may legally position themselves during a faceoff or during in-game play.
Spot and circle dimensions Both the centre faceoff spot and centre faceoff circle are blue. The circle is 30 feet (9m) in diameter, with an outline thick, and the faceoff spot is a solid blue circle in diameter. All of the other faceoff spots and circles are colored red. Each spot consists of a circle in diameter (as measured from the outermost edges) with an outline thick. Within the spot, two red vertical lines are drawn from the left and right inner edges, and the area between these lines is painted red while the rest of the circle is painted white.
Goal posts and nets At each end of the ice, there is a goal consisting of a metal goal frame and cloth net in which each team must place the puck to score. According to NHL and IIHF rules, the entire puck must cross the entire goal line in order to be counted as a goal. Under NHL rules, the opening of the goal is wide by tall, and the footprint of the goal is deep.
Crease The crease is a special area of the ice in front of each goal that is designed to allow the
goaltender to perform without interference. In North American professional hockey, the goal crease consists of straight lines extending perpendicularly from the goal line outside each goal post, connected by an arc with a radius; red hashmarks are added just inside the straight lines, from the goal line and extending into the crease from either side. The entire area of the crease is typically coloured blue for easier visibility.
Goaltender trapezoid ("Martin Brodeur" Rule) goaltender
Martin Brodeur (top left) positions himself along the net during a 2008 game against the
Boston Bruins. Goaltenders with good puck-handling abilities like Brodeur led to the trapezoidal zone behind the net to limit where the goaltender can legally play the puck behind the goal line During the 2004–05
American Hockey League (AHL) season, an experimental rule was implemented for the first seven weeks of the season, instituting a
goaltender trap zone, more commonly called
the trapezoid in reference to its shape. Under the rule, it is prohibited for the goaltender to handle the puck anywhere behind the goal line that is not within the trapezoidal area. If they do so they are assessed a minor penalty for delay of game that is served by a teammate. The motivation for the introduction of the trapezoid was to promote game flow and prolonged offensive attacks by making it more difficult for the goaltender to possess and clear the puck. The rule was aimed at reducing the effectiveness of goaltenders with good puck-handling abilities, such as former
New Jersey Devils and
St. Louis Blues goaltender
Martin Brodeur, for whom the rule is nicknamed. The area consists of a centred, symmetrical
trapezoid. The bases of the trapezoid are formed by the goal line and the end boards. The base on the goal line measures — widened from the original for the
2014-15 NHL season onwards — and the base along the end boards measures , with the depth behind the goal line-to-boards distance specified at . The seven-week experiment proved so successful that the AHL moved to enforce the rule for the rest of the season, and then the rule was approved by the NHL when play resumed for the 2005–06 season. The
ECHL, the only other developmental league in the Professional Hockey Players Association along with the AHL, also approved the rule for 2005–06. The trapezoid was later adopted by the
KHL for the 2019–20 season, and by the
IIHF in 2021.
Referee's crease The ''referee's crease'' is a semicircle in radius in front of the scorekeepers bench. Under
USA Hockey rule 601(d)(5), any player entering or remaining in the referee's crease while the referee is reporting to or consulting with any game official may be assessed a
misconduct penalty. The USA Hockey casebook specifically states that the imposition of such a penalty would be unusual, and the player would typically first be asked to leave the referee's crease before the imposition of the penalty. The
NHL has a similar rule, also calling for a misconduct penalty. Traditionally, captains and alternate captains are the only players allowed to approach the referee's crease. == Zones ==
