basketball court


a basketball court is a surface containing a rectangular floor where the game of bball takes place and usually consists of a basket at each end of the floor. Professional bball like indoor basketball, the field is made out of a wood which in most cases is maple. These wooden floors are highly polished and have a complete 10-foot rim that accompanies it. While the indoor basketball court is generally made from wooden materials, the outdoor basketball court surface is another one that is made from paving structures that consist of either asphalt or concrete materials.


There are a lot of variations and differences concerning bball court dimensions based on the actual level of play. On this blog post, we are going to be plain in explaining some of the various variations and sizes of the courts with charts where possible. We strongly believe the information herein will help anybody understand their direction on the bball court argument of any sort.

Basketball Full-Court Dimensions

Let’s start with basketball full-court dimensions. As written above, a full-court floor is going to depend on the level of play. And I can state according to NBA and FIBA that the followings are the dimensions of full-court play for levels like:

  • Youth full-courts: this has 74 feet long by 42 feet wide court dimensions and floor.
  • High school full-courts: here the school kids enjoy and boost 84 feet long by 50 feet wide full-courts dimension.
  • College/professional full-courts: the professional and college full-courts dimensions are 94 feet long and 50 feet wide.
  • International Bball Federation full-courts: This court is used by IBF which is a body that governs international competitions. They have a whelming minimum court of 32,000 mm, or 104.9 feet long and 19,000 mm or 62.3 feet long

Basketball Half-Court Dimensions

This is another court dimension that cuts into two the length of a full-court, called basketball half-court dimensions. What this court does is simply divide the length of a full-court leaving the width intact from its very original court size. There are variations as well for the sizes depending also on the level of play and can be seen below:

  1. Youth half-court: the size of this court is solely 37 feet by 42 feet from the full.
  2. High school half-court: this one has 42 feet by 50 feet.
  3. College/professional half-court: players who play on these levels of exercise enjoy their games on 47 feet by 50 feet court.
  4. IBF half-court: international bball federation’s games are played on a court of 52 feet by 31 feet court.

Now let’s try to understand better these terms as they should be. A half-court bball court often consists of a hoop, a free-throw line as well as a three-point arc. Let’s talk about this broader a bit.

The free-throw line on a half-court is the line that you can see or measure that weighs 15 feet in the front plane of a backboard.

Just as the free-throw lines sound, there is the one we call the three-point arc. This one weighs 19.75 feet and for high school and women’s college court, its located from the middle of a basket. In the college basketball courts for men, you will notice that the three-point line is roughly 21 feet from the middle of the basket. At almost 24 feet, the professional three-point line is the farthest from the basket.

What is a bball court size?

A lot of times the question we get is always what’s the regulation bball court dimensions? Well as we said above, the dimensions are 94 feet long by 50 feet wide.

For NBA, WNBA courts are not the same as the FIBA and the Olympics court.  For Fiba and Olympics sports, the sizes of this court are slightly smaller with 91.9 feet by 49.2 feet in meters than the NBA and WNBA court.

High school basketball court dimensions

For junior and high school court, there is a bball court measurement of 84 feet long by 50 feet wide. The marking of the court shows the dimensions we get properly.

High School Bball Court Diagram

Court dimensions in meters

Dimensions and metric sizes of a pro court Washington dc measures 28.68 meters long by 15.24 meters wide. Again the high school court measures 25.6 meters long.

Half-court dimensions?

The half-court dimensions have been discussed above and for reference purposes, it measures 47 feet long for professionals in Washington dc and 42 feet long for home high school kids.

Half-court dimensions for a backyard

For any available home youth half-court bball, the court measures 42 feet long by 37 feet wide. The high school kids’ half-court is slightly higher and measures about 50 feet long by 42 feet wide.

Backyard court dimensions

I know the backyard court dimensions will sound a bit confusing if you are a beginner. knowing these backyard basketball court sizes will have a great role in determining how far you will go. Well, the size is not fixed and can be decided by you or your coach. Though I have seen most backyard court measures 90 feet long by 50 feet wide.

Youth court dimensions – Middle School and High school

We have the middle school court size which measures about 74 feet long by 42 feet wide in meters. The difference is that high school fields are a bit larger and measures about 84 feet long by 50 feet wide. unlike the backyard bball court

Basketball backboard dimensions

There is a standard 72” width for regulation bball backboards.  It also has a height of 42” and 183 cm, an inner rectangle which has 24” and a 110 cm,  18” wide and a 61 cm, as well as a 45.7 cm tall. Smaller and little fan-shaped backboards are usually used for casual and non-regulation courts such as the backyard court. Gym Rims for the bball are usually hanged at about 10”, 3.05 m above the field floor.

Fan-Shaped Backboard

1 example of non-regulation backboards is the fan-shaped backboards which you can see on any casual and non-serious court such as indoor side court.  The fan-shaped backboards are often lesser than a normal regulation backboard which are rectangular and comes with a width of 54” and 137.2 cm plus 33” in height and 83.8 cm

Bball Court Lines on a Typical Court


The sideline of a bball court consists of two parallel lines that run across the length of the court. The width of the court is what decides where the location of the line is found. The width is usually 50 feet wide along the Baseline as well as the End lines; hence the court size of the area is established according to Wikipedia the last time I checked.


on the court, we have a baseline/end line that runs from sideline to sideline just behind the backboard which is located at the end of the court. These sidelines are seen just 4 feet behind every basket, with a width of 50 feet. These two terms are interchangeable depending on the team that has the game. When we talk of the term baseline, we mean an offensive end of the court, while Endline is talking about the backside of the court or defensive end of a court.

Mid Court Line:

This is a line that divides the court into half. When a team is handling the ball offensively, and the game goes across a mid-court line, we have a boundary line that reduces the area of the offensive team to half the court. On the other hand, most levels of exercise will have 8 to 10 seconds to bring the ball across the mid-court line offensively.

Three-Point Line:

There are field goals that are made from this area and carry a weight of three points since it’s done from the three-point arc. We have a varying distance of the three-point line from the basket based on the level of exercise that we participate on.

Free Throw Line:

It’s a boundary line that’s called upon when doing shooting free throws. Based on the level of exercise, it’s normally 15 feet from the gym bball backboard dimensions which hold the basket. While attempting a free-throw, the shooter is not expected to put a foot or come close and across this line till the ball makes a goal on the rim or strikes the rim. This line is used to also know the three seconds area of the court.

Free Throw Circle:

Every free throw circle has a 12 feet diameter. These circles are used, usually when there is a jump shot need or free throw. When attempting a throw, the shooter must stay inside a throw area circle. It’s expected of non-jumpers to stay outside the circle till the jumpers tap the ball.

Lane Line:

This line is called the lane lines because it runs from the free-throw line unto the baseline. On different levels, the lanes line normally has a shape and width that will vary. The lane lines have what we call the lane spaces markings that are used to separate and make alignment to non-shooters.

The opposing team occupies the first lane space on both sides of baskets from the free-throw shooter. While this is ongoing, non-shooters shouldn’t step their feet into the three seconds area of the court until the ball moves away from the throw shooter’s palms.

Center Circle:

This circle is a 12-foot diameter circle which is positioned in the center of the court. It’s normally used to commence the game and other jump ball situations. While the ball is about to start, only the jump balls shooters are expected to be in this circle. This means that non-jumpers are to remain outside the circle until the ball gets a touch from the jumpers.

The key area is a painted area under the basket. It’s as well-referred as the shaded lane or key area. NBA family measure this lane at 16 feet. The NCAA says it has a measurement of 12 feet for low post areas.

There should be a distance of 15 feet running from the key to the backboard for both institutions (NBA & NCAA). FIBA measures the key area as 12 feet wide from the free-throw line. It is also 6 meters at the end line. The reason the key post is there is to prevent gamers from staying under the basket for a long time.

Low Post Area:

This is the new area that is closest to the basket, and the line is just after the free-throw lane. gamers who are very skillful at low posts games normally score lots of points per game without having to lift or do a jump shot.


The perimeter is located inside the 3 point line and as well as outside the free-throw lane. This is where you will take medium-range shots or the perimeter shots.

The backcourt and frontcourt:

You should think of the court in entirety exactly as two half-courts. This is to be divided into the backcourt and frontcourt. The offensive team’s basket is located at the half-court which is the frontcourt while the other half-court is seen as the other half. It means that a team’s backcourt is another team’s frontcourt.

The Basketball courts line:

The Foul Line: The distance of the foul line is approximately 15’ for every court. This is the distance measured from the foul line down to the front side of the backboard. It also has a baseline of 18’ 10”.

The Key: For NBA and FIBA family, there is a 16 feet wideness for the free throw lane or “the paint”, also college, High schools, and junior high exercise have a 12ft wideness area while there is a 15ft area which extends from the backboard down to the throw line.

Circles: The court has a three 6’ circle on it. each has a circle on each center end of the foul line and another quality circle at the center of the field.

3 Point Line or Arc

  • High School: 19.75 ft (6.01 m)
  • NCAA: 20.75 ft (6.32 m):
  • WNBA and FIBA: 21.65 ft (6.60 m) to 22.15 ft (6.75 m):
  • NBA: 22 ft (6.71 m) to 23.75 ft (7.24 m):

Bball Court Layout

There was a change to the FIBA Bball courts layouts in the year 2010 which brought the field into line with NBA layout. The particular changed moved away with the trapezoidal shooting key.

It was then replaced with a key in a rectangle. The projection of the backboard and entire dimensions of the field remains unchanged to date. This means that the old pattern field can be remarked with the new markings of the modern-day field without interfering with bball goals.

Team bench areas

The team workbench areas are marked outside the field limited by 2 quality lines. There must be 14 seats available in the team bench area for the team bench personnel which include coaches, assistant coaches, substitutes, and team followers. Any other persons must be at least 2m behind the team bench.

No-charge semi-circle areas

The no-charge semi-circle lines shall be marked on the field, limited by:

  • A semi-circle with a radius of 1.25m measured from the point on the floor beneath the exact center of the basket to the inner edge of the semi-circle. 

The semi-circle is joined to

  • Two parallel lines are perpendicular to the end lines, the inner edge 1.25m from the point on the floor beneath the exact center of the basket, 0.375m in length, and ending 1.20m from the inner edge of the end line.

The no-charge semi-circle areas are completed by imaginary lines joining the ends of the parallel lines directly below the front edges of the backboards.  The no-charge semi-circle lines are not part of the no-charge semi-circle areas.


All spectators must be seated at a distance of at least 5m from the outer edge of the boundary line of the playing field.

3×3 basketball

The main rules of 3×3 are as follows:

  • 1 basket on 1 half-court.
  • 2 teams of 3 players and up to 1 substitute per team.
  • 12 seconds shot clock.
  • 1st team to reach 21 points or best after 10 minutes wins.

Playing field

A regular 3×3 court playing surface is 15m wide x 11m long.

The field has a regular court-sized zone, including a free throw line (5.80m), a two-point line (6.75m), and a “no-charge semi-circle” area underneath the 1 basket. 

Half a traditional field may be used.


Mini‑­bball is a game for boys and girls who are eleven years or under in the year the competition begins.

Mini‑­bball is played by 2 teams of 5 players each. Each team aims to score in the opponents’ basket and to prevent the other team from scoring.

The Original Cage Matches

In the early days of pro bball, the game was done inside an actual cage. The reasons were more about practicality than about safety. The rule for who got to inbound a ball that left the field was “whoever got to it first,” so organizers took to putting up a cage so the ball could never go out of bounds in the first place and that was how it was last derived.

Those first court of basketball were about a third smaller than they are today, and the cages provided a physical boundary and an extra immovable for savvy teams. Could you imagine how much different the game of bball would be today if those cages had stuck around?

The Alternative Key Designs

Basketball Key

Another designed key to this feature is responsible for the name “key.” Have you ever thought about how a rectangular area under a basket got such a random name?

The reason is that the original area was much narrower during this work, while the circle surrounding the free throw line was the same size. These two factors combined to create a shape that resembled an old-fashioned key. In 1951, the key was widened to 12 feet and later to the 16 feet we see now in the NBA and FIBA.

While the term lives on, the time has erased any record of its design and original reference. And for the record, the official name for this feature is “free throw lane,” which isn’t a phrase many of us hear often.

And that’s a wrap on the history of basketball’s court dimensions.


The Story Behind the 10-Foot High Hoop

It would appear the 10-foot basketball hoop is the result of a careful work calculation that considers the human anatomy and mechanics of the game. After all, even the tallest players today have to jump to dunk a game, and a ten-foot-high rim gives a comfortable target to shoot for at a distance. But as we see so often in history, the truth is much more mundane.

When James Naismith dreamed up the game in Springfield, MA in 1891, the railing he chose to hang the baskets on was ten feet off the ground. So, while everything else about the sport has changed since that first game, the baskets are still right where Dr. Naismith hung them.

The History of the Three-Point Line

The three-point line is arguably the most recognizable aspect of a bball field dimensions and part of the reason why is attributed to the history surrounding this semicircle.

The first instance of the three-point line appeared in the American Basketball League in 1961, a full 70 years after Dr. Naismith invented the game. The line was added to increase excitement, but the league folded in just 1 and a half seasons, so the idea never had a chance.

In 1967 work, the next competitor to the NBA arrived. The American Bball Association, or ABA, instituted the three-point line from the very start, and it was a huge success. The ABA had many exciting innovations that produced a better product for the fans. But ultimately, there was not enough room for two professional basketball organizations, so the NBA and ABA merged last in 1976.

The three-point line, however, was not included in the merger! The decision-makers in Washington dc in the NBA at the time were too stubborn to adopt such a radical change. They held out for three years before implementing the three-point line in the 1979-1980 season. The NCAA didn’t integrate it until the year 1986, and it didn’t arrive on high school bball field until the year 1987.

That isn’t the end of the story, however. The line was last moved closer for three seasons in the year the ‘90s to try to boost scoring, but it was quickly moved back to its original place. Taking the idea to the extreme, the NBA family has even admitted to having discussions about a four-point line. Ultimately, we’ll believe it when we see the basketball court live.
