A basketball court measures 91.86 feet long by 49.21 feet broad. A court's entire playing space is 4520.43 ft2 and 7290.5 ft2 if run-offs and sidelines are included.
A basketball court is the most common type of sports field. Other common types include football fields, baseball diamonds, and tennis courts. All have dimensions that are multiples of 9 inches (or 90 feet), with football being the longest at 100 yards and tennis being the shortest at 30 feet. Court dimensions are also factors of 12 or 60 or 900 inches. The NBA plays on 90 foot rims, while in college it's usually 68 feet 6 inches. In high school it can be as small as 50 feet by 25 feet.
The term "court" can be used to describe any open area where athletic events are held. At schools where athletics are popular, such as North Carolina State University and the University of North Carolina, the term "court" has become synonymous with the playing surface for these teams: the Wolfpack's James Madison Memorial Stadium is 90,000 cubic yards of natural grass and the Heels' Carmichael Arena is 10,000 square feet of hardwood.
Courts have been built in many different sizes and shapes. The three most common are the rectangular shape, the circular shape, and the elliptical shape.
What is the size of a basketball court? The dimensions of a typical backyard basketball court are 60 feet by 90 feet (for reference, a regulation NBA court is 50 feet by 94 feet). So, a basketball court that is 60 feet wide and 90 feet long would be suitable for many homes with backyards. You should also consider how much use you expect to get out of your basketball court before making a decision on its size.
How do you measure a basketball court? Basketball courts don't have exact measurements; instead they are usually described in terms of their width and length. The width of the court is measured from one free-throw line to the other, while the length is measured along the midpoint between the top edges of the baskets.
So, if you want to know what size basketball court you need, first figure out how much space you have available behind your house. If you can fit a football field inside your home, then you need a basketball court that is at least 60 feet wide.
Now, you need to decide what size basket you want to put up. There are two types of baskets used in basketball courts: half-court and full-court. A half-court basket is 36 inches high, while a full-court basket is 45 inches high.
94 feet by 50 feet Basketball courts come in a variety of sizes. The National Basketball Association (NBA) court measures 94 by 50 feet (28.7 by 15.2 m). The court is somewhat smaller under International Basketball Federation (FIBA) guidelines, measuring 28 by 15 meters (91.9 by 49.2 ft). The size of the court depends on how many people want to play at one time and how large an audience is watching.
There are only 90 minutes in an NBA game, which means that there is quite a bit of downtime between plays. Before each period starts, the referees will survey the court to make sure that it is clear before they begin. If any debris is on the floor, then play will be delayed while they clean it up. A ball girl also stands near the free-throw line to make sure players don't trip over anything as they rush toward the basket for layups or open shots.
The court is divided into five regions: top left, bottom left, top right, bottom right, and center. These areas are where the referees position themselves so they can control the action on the court. For example, if the ball goes out of bounds near the top left corner, then a referee would go there to ensure that no player has possession of the ball.
Each referee has a different responsibility during games.
Basketball courts come in a variety of sizes. Court sizes vary greatly in amateur basketball. A college or university court can be as large as the NBA's (100 by 80 feet [30.5 by 24.4 m]), while an adult league game involves courts that are much shorter (usually around 40 feet [12.2 m]).
A high school court is usually about 70 feet by 10-15 feet (21 by 3.6-4.8 m), although some are as small as 60 feet by 9 feet (18 by 2.7 m) and others are as large as 90 feet by 20 feet (27 by 6 m).
In Europe, courts range from 30 meters by 12 meters (98 feet by 39 feet) to 45 meters by 15 meters (148 feet by 48 feet).
In Australia, there are three levels of competition: national, state, and territory. National competitions involve teams from different states or territories. State competitions are between teams from the same state. Territory competitions are between teams from different territories.
National tournaments are held over a two-week period in late September/early October. They include all Australian universities, as well as some secondary schools.
Outdoor recreational basketball courts vary in size even more, and are frequently merely half-courts. Most full-size courts are 70 to 94 feet (21.34 to 28.65 m) long and 40 to 50 feet (12.19 to 15.24 m) broad, with a length-to-width ratio of less than two to one. Half-size courts are generally about 35 to 45 feet (10.7 to 13.7 m) long and 20 to 25 feet (6.1 to 7.6 m) wide, with a length-to-width ratio of about three to one.
The area of a basketball court is calculated by multiplying the court's width by its length. For example, a court that is 90 feet long and 12 feet wide has 3,600 square feet of space.
Basketball courts are usually painted black or used as a backdrop for other sports such as tennis or football. In some countries such as China, Japan, and South Korea, basketball is popular enough to have its own season, during which time public venues may be used for games.
There are many different types of basketball courts, including indoor, outdoor hard, outdoor synthetic, and playgrounds. Indoor courts are those where play takes place under normal atmospheric conditions, while outdoor courts can be either natural grass or artificial.
A conventional basketball court in the professional or collegiate ranks is 94 feet long and 50 feet broad, although many high school courts are 84 feet long and 50 feet wide. Junior high courts can be considerably smaller, measuring 74 feet by 42 feet. Based on this, the dimensions of a basketball half court would be 47 x 50, 42 x 50, or 37 x 42. The area of a half court is therefore 1620 square feet.
The NBA has a 20-foot radius around each basket, which means that the width of a half court is 40 feet. The height depends on how deep you want to go into the hoop; for simplicity's sake, we'll say it's 10 feet high.
There are about 6 million people in the United States who play basketball. That means there are about 30 million ways to divide up the court into halves.
Basketball players usually divide their own courts by drawing imaginary lines in the dirt with a pointer, but they can also use flags or nets. A college coach might have enough space to build a full size court, but most junior high and high school facilities do not. In that case, the coach would have to make do with what's available.
It's helpful if one side of the court is better suited for shooting because that's where most players like to be when they have the ball.
