Ice Hockey Rink Dimensions

"An ice hockey rink is an ice rink that is specifically designed for ice hockey, a team sport. It is rectangular with rounded corners and surrounded by a wall approximately 1 meter (40-48 inches) high called the boards. ...
There are two standard sizes for hockey rinks: one used primarily in North America, the other used in the rest of the world.
International.
Hockey rinks in most of the world follow the International Ice Hockey Federation (IIHF) specifications, which is 61 metres (200 ft) × 30.5 metres (100 ft) with a corner radius of 8.5 metres (28 ft). The distance from the end boards to the nearest goal line is 4 metres (13 ft). The distance from each goal line to the nearest blue line is 17.3 metres (57 ft). The distance between the two blue lines is also 17.3 metres (57 ft).
North American.
Most North American rinks follow the National Hockey League (NHL) specifications of 200 feet (61 m) × 85 feet (26 m) with a corner radius of 28 feet (8.5 m). The distance from the end boards to the nearest goal line is 11 feet (3.4 m). The NHL attacking zones are expanded, with blue lines 64 feet (20 m) from the goal line and 50 feet (15 m) apart."

"Markings.
Lines.
The centre line divides the ice in half crosswise. It is used to judge icing, meaning that if a team sends the puck across the centre line (red line), blue line and then across the goal line (that is to say, shoots or dumps the puck past the goal line from behind their own side of the centre line) it is said to be icing. ...
Faceoff spots and circles.
There are 9 faceoff spots on a hockey rink. Most faceoffs take place at these spots. There are two spots in each end 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 in game play. ...
Spot and circle dimensions.
Both the center faceoff spot and center faceoff circle are blue. The spot is a solid blue circle 12 inches (30 cm) in diameter. Within the spot is a center, a circle 30 feet (9.1 m) in diameter, painted with a blue line 2 inches (5.1 cm) in width.
All of the other faceoff spots have outlines 2 inches (5.1 cm) thick, forming a circle 2 feet (0.61 m) in diameter measured from the outsides of the outlines, and are filled in with red in all areas except for the 3 inches (7.6 cm) space from the tops and bottoms of the circles, measured from the insides of the outline. ...
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 earn points. According to NHL and IIHF rules, the entire puck must cross the entire goal line in order to be counted as a goal. ...
Goal area.
The crease is a special area of the ice designed to allow the goaltender to perform without interference. In most leagues, goals are disallowed if an attacking player enters the goal crease with a stick, skate, or any body part before the puck. For the purposes of this rule, the crease extends vertically from the painted lines to the top of the goal frame. ...
Goaltender trapezoid.
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. ...
Referee's crease.
The referee's crease is a semicircle ten feet in radius in front of the scorekeepers bench." [Ice hockey rink. Wikipedia]

This seating plan sample shows the stadium seat layout.
"A modern stadium (plural stadiums/ stadia) is a place or venue for (mostly) outdoor sports, concerts, or other events and consists of a field or stage either partly or completely surrounded by a structure designed to allow spectators to stand or sit and view the event. ...
Spectator areas and seating.
An "all-seater" stadium has seats for all spectators. Other stadiums are designed so that all or some spectators stand to view the event. The term "all-seater" is not common in the U.S., perhaps because very few American stadiums have sizeable standing-only sections. ...
The spectator areas of a stadium may be referred to as bleachers, especially in the U.S., or as terraces, especially in the United Kingdom, but also in some American baseball parks, as an alternative to the term tier. Originally set out for standing room only, they are now usually equipped with seating. Either way, the term originates from the step-like rows which resemble agricultural terraces. Related, but not precisely the same, is the use of the word terrace to describe a sloping portion of the outfield in a baseball park, possibly, but not necessarily for seating, but for practical or decorative purposes. ... Many stadiums make luxury suites or boxes available to patrons at high prices. These suites can accommodate fewer than 10 spectators or upwards of 30 depending on the venue. Luxury suites at events such as the Super Bowl can cost hundreds of thousands of dollars." [Stadium. Wikipedia]
