Artificial turf in the context of Hockey ball

Field hockey, or simply hockey in Asia, Europe and Oceania, is a fast-paced team sport in which two teams of eleven players (ten field players and one goalkeeper) use curved sticks to maneuver a small, hard hockey ball towards the rival team's shooting circle and then into the goal. The team with the most goals at the end of play wins the match.

Matches are played on grass, watered turf, or artificial turf, although grass has become increasingly rare as a playing surface. Indoor hockey is usually played on a synthetic hard court or hardwood sports flooring, and beach field hockey is played on sand.

A football pitch or soccer field is the playing surface for the game of association football. Its dimensions and markings are defined by Law 1 of the Laws of the Game, "The Field of Play". The pitch is typically made of natural turf or artificial turf, although amateur and recreational teams often play on dirt fields. Artificial surfaces are allowed only to be green in colour.

All line markings on the pitch form part of the area which they define. For example, a ball on or above the touchline is still on the field of play, and a foul committed over the line bounding the penalty area results in a penalty. Therefore, a ball has to completely cross the touchline to be out of play, and a ball has to fully cross the goal line (between the goal posts) in order for a goal to be scored; if any part of the ball is still on or above the line, a goal is not scored and the ball is still in play.

The rectangular field of play used for American football games measures 100 yards (91.44 m) long between the goal lines, and 160 feet (48.8 m) (53.3 yards) wide. The field may be made of grass or artificial turf. In addition, there are two end zones on each end of the field, extending another 10 yards (9.144 m) past the goal lines to the end lines, for a total length of 120 yards (109.7 m). When the "football field" is used as unit of measurement, it is usually understood to mean 100 yards (91.44 m), although technically the full length of the official field, including the end zones, is 120 yards (109.7 m). The total area of the field is 57,600 sq ft or 5,350 m. There is a goal centered on each end line, with a crossbar 10 feet (3.0 m) above the ground and goalposts 18 feet 6 inches (5.64 m) apart (in college and the NFL) extending at least 35 feet (11 m) above the crossbar. Between the goal lines, additional lines span the width of the field at 5-yard intervals. This appearance led to the use of the term "gridiron" in the 1880s. For a few years in the early 20th century, lines perpendicular to the lines at 5-yard intervals spanned the length of the field, giving it a checkerboard-like appearance.

This article mainly describes the field used in the National Football League, college football, and other leagues playing the standard form of outdoor 11-man football. Other variants of American football such as nine-man or arena football typically use smaller fields with smaller end zones.

Stampesletta is a multi-use stadium complex in Lillehammer, Norway. Owned and operated by Lillehammer Municipality, it consists of a track and field venue, an artificial turf football field, three natural grass football fields, a gravel field and natural grass training pitches. In addition, it features a club house, locker facilities and a grandstand between the athletics and artificial turf fields. The venue is located about 1 kilometer (0.6 mi) from the town center, and serves as the home ground for the Second Division side Lillehammer FK, Lillehammer KFK, Roterud IL in football, and Lillehammer IF in athletics.

Construction of Stampesletta started in 1946 and the grass football field opened in 1949. A now removed equestrian exhibition area opened in 1958, and in 1973 the track and field venue opened. The latter received a hard surface in 1982. During the 1994 Winter Olympics, Stampesletta itself was used for medal ceremonies, attracting crowds of up to 30,000 people. The area around Stampesletta was sometimes referred to as the Olympic Park, as it also has in its immediate vicinity the ice hockey venues Håkons Hall and Eidsiva Arena, the ski jumping hill Lysgårdsbakken, and Kanthaugen Freestyle Arena. The two halls are often regarded as part of Stampesletta. The arena is used as the goal are for Birkebeinerrittet and Birkebeinerløpet, and from 1932 to 1992 for Birkebeinerrennet. Stampesletta hosted the Norwegian Athletics Championships in 1977, 1995 and 2009, and annually hosts Norway's second-largest track and field tournament, Veidekkelekene. Stampesletta is scheduled to host the opening and closing ceremonies of the 2016 Winter Youth Olympics.

FieldTurf is a brand of artificial turf playing surface. It is manufactured and installed by FieldTurf Tarkett, a division of French company Tarkett. FieldTurf is headquartered in Montreal, Quebec, Canada, and its primary manufacturing facility is located in Calhoun, Georgia, United States. With a design intended to more accurately replicate real grass, the new product rapidly gained popularity in the late 1990s.

Loftus Road, currently known as MATRADE Loftus Road Stadium for sponsorship reasons, is a football stadium in Shepherd's Bush, West London, Greater London, England, which is home to Queens Park Rangers Football Club, with a capacity of 18,439.

In 1981, it became the first stadium in British professional football to have an artificial pitch of Omniturf installed. This remained in use until 1988, after which a natural grass pitch was reintroduced.

A soccer-specific stadium, mainly in the United States and Canada, is a sports stadium either purpose-built or fundamentally redesigned for soccer and whose primary function is to host soccer matches, as opposed to a multi-purpose stadium which is for a variety of sports. A soccer-specific stadium may host other sporting events (such as lacrosse, American football and rugby) and concerts, but the design and purpose of a soccer-specific stadium is primarily for soccer. Some facilities (for example SeatGeek Stadium, Toyota Stadium and Historic Crew Stadium) have a permanent stage at one end of the stadium used for staging concerts.

A soccer-specific stadium typically has amenities, dimensions and scale suitable for soccer in North America, including a scoreboard, video screen, luxury suites and possibly a roof. The field dimensions are within the range found optimal by FIFA: 110–120 yards (100–110 m) long by 70–80 yards (64–75 m) wide. These soccer field dimensions are wider than the regulation American football field width of 53+1⁄3 yards (48.8 m), or the 65-yard (59 m) width of a Canadian football field. The playing surface typically consists of grass as opposed to artificial turf, as the latter is generally disfavored for soccer matches since players are more susceptible to injuries. However, some soccer-specific stadiums, such as Portland's Providence Park and Creighton University's Morrison Stadium, do have artificial turf.
