A regulation basketball half court is usually 2,350 square feet. This is half of a standard NBA or NCAA court, which measures 94 feet long and 50 feet wide. So, if a full court is 4,700 square feet, then half of that is 2,350 square feet. This area is perfect for many types of basketball play. You can use it for 3-on-3 games. It is also good for skill drills and practice. Knowing the square footage of a key or the full basketball court size helps in planning. This includes building your own court or setting up an event.

Getting to Know Basketball Court Dimensions
Playing basketball needs a court of a certain size. These sizes can change based on the level of play. The game of basketball has rules for court size. These rules help make the game fair. They also make sure players have enough space. We often talk about the full basketball court size. But for many uses, the half court is what matters most.
What Makes a Court Standard?
Basketball courts are mostly rectangles. They have specific lines drawn on them. These lines tell players where to stand and move. The main lines are the sidelines and baselines. There is also a mid-court line. This line divides the court into two halves. A center circle is at the middle of this line. Each half has a key, a free-throw line, and a three-point line. All these parts make up the total basketball court size.
The Main Parts of a Court
Each part of a basketball court has a special role.
* Sidelines: These are the long lines along the court.
* Baselines (or Endlines): These are the short lines behind each hoop.
* Mid-court line: This line cuts the court in half.
* Center circle: This is where the game starts with a jump ball.
* The Key (or Paint): This is a marked area under each basket. Players cannot stay here for too long without the ball. We will look at the square footage of a key later.
* Free-throw line: This line is at the end of the key. Players shoot free throws from here.
* Three-point line: Shots made from behind this line are worth three points.
All these parts combine to form the overall basketball court size. Knowing these parts helps in understanding the court’s area.
Figuring Out Half Court Area
The size of a basketball court depends on who is playing. Professional games, college games, and high school games use different sizes. This means the half court area calculation will also change. It is important to know which court size you are talking about. This way, you get the correct area.
NBA Court Square Footage Explained
The NBA uses the largest court size. These courts are made for the best players in the world. They provide plenty of space for fast play and big moves.
How Big is a Full NBA Court?
A full NBA court measures 94 feet long. It is 50 feet wide.
To find its total area, we multiply length by width.
* Full NBA court area = 94 feet * 50 feet = 4,700 square feet.
This is the standard regulation basketball court dimensions for professional play.
The Half Court Area Calculation for NBA
To find the half court area for an NBA court, we simply divide the full area by two.
* NBA half court area = 4,700 square feet / 2 = 2,350 square feet.
This is a large space. It is often used for team practices. Many home courts are built to this size. This ensures the feel of a real NBA court. This is the most common answer when asking “How many square feet is half a basketball court?”.
NCAA Basketball Court Dimensions and Half Size
College basketball also uses specific court sizes. The NCAA sets these rules. The NCAA basketball court dimensions are the same as the NBA. This helps players move easily from college to pro leagues.
NCAA Court Facts
Like the NBA, an NCAA court is 94 feet long. It is 50 feet wide.
* Full NCAA court area = 94 feet * 50 feet = 4,700 square feet.
These regulation basketball court dimensions are key for competitive college play.
Half Court Area for College Games
The half court area for NCAA is also the same as the NBA.
* NCAA half court area = 4,700 square feet / 2 = 2,350 square feet.
Many college teams use one half of their main court for drills. Or they have dedicated practice court size areas of this dimension. This allows players to work on specific skills. They can do this without needing a full court.
High School Basketball Court Dimensions
High school courts can be a bit different. Some high schools use the same size as NBA or NCAA. But many older or smaller high schools use a slightly smaller court.
Common High School Court Sizes
The most common high school basketball court dimensions are 84 feet long and 50 feet wide.
* Full high school court area = 84 feet * 50 feet = 4,200 square feet.
However, some newer high schools or those with more space might use the 94×50 feet court. It is important to check the specific court.
Calculating Half Court for High Schools
If a high school court is 84 feet long and 50 feet wide:
* High school half court area = 4,200 square feet / 2 = 2,100 square feet.
This is a common size for many community centers as well. It is a good size for general play and youth leagues. It is slightly smaller than the NBA half court. But it still offers good space.
Youth and Practice Court Size Variations
Basketball is played by people of all ages. Younger players often use smaller courts. This helps them learn the game better. These smaller courts make the game more fun for them.
Smaller Courts for Younger Players
Youth basketball leagues often use even smaller courts. These courts might be 74 feet long and 42 feet wide.
* Full youth court area = 74 feet * 42 feet = 3,108 square feet.
This size is common for junior high or elementary school gyms. It makes the hoops feel closer. It also makes the court less tiring for smaller kids.
Half Court for Youth Games
For a youth court that is 74 by 42 feet:
* Youth half court area = 3,108 square feet / 2 = 1,554 square feet.
This is a much smaller basketball half court dimensions. It is perfect for home use. It is also good for small practice court size areas. It teaches kids the basics of the game. They learn dribbling, shooting, and passing in a more confined space.
More About Court Sections
Beyond the total court size, individual sections have their own areas. These areas are important for game play. They also help when thinking about court layout or design.
The Square Footage of a Key (Paint Area)
The key, also called the “paint,” is a key part of the court. It is the area under the basket. Players cannot stay in this area for more than three seconds. This rule keeps the game flowing. The square footage of a key changes slightly with court type.
NBA/NCAA Key Size
For NBA and NCAA courts, the key is 16 feet wide. It extends 19 feet from the baseline to the free-throw line.
* NBA/NCAA key area = 16 feet * 19 feet = 304 square feet.
This is a big area. It is where much of the action happens. Drives to the basket, rebounds, and post-up plays mostly occur here.
High School Key Size
For high school courts, the key is usually 12 feet wide. It also extends 19 feet from the baseline.
* High school key area = 12 feet * 19 feet = 228 square feet.
This smaller key means less space under the basket. It can make scoring inside a bit harder. It affects how players move and defend.
Beyond the Key: Three-Point Line Area
The three-point line is a curved arc. It is set at different distances from the basket. Shots made from beyond this line count for three points. This line adds excitement to the game. It also affects how teams play offense and defense.
- NBA: The three-point line is 23 feet 9 inches (23.75 feet) from the center of the basket. It is 22 feet at the corners.
- NCAA: The three-point line is 22 feet 1 and 3/4 inches (22.17 feet) from the center of the basket.
- High School: The three-point line is 19 feet 9 inches (19.75 feet) from the center of the basket.
The area outside the key and inside the three-point line is also important. It is where many mid-range shots are taken. The space beyond the three-point line is crucial for offensive spacing. It lets players spread out. This creates driving lanes to the basket. When planning a half court, this area is vital. It dictates where players can stand and shoot.
Why Knowing Half Court Size Matters
Knowing the exact square footage of a half court is useful for many reasons. It is not just for math lessons. It helps people plan, build, and manage spaces.
Building Your Own Basketball Half Court Dimensions
Many people dream of having a basketball court at home. A half court is usually more practical than a full court. It takes up less space. It also costs less to build. Knowing the specific basketball half court dimensions is the first step. You need to know if you have enough backyard space. Or if a garage can be turned into a court. For an NBA-sized half court, you need 2,350 square feet. This is a space roughly 50 feet by 47 feet. This includes some extra room around the lines. Knowing this helps you pick the right spot. It also helps you get proper materials.
Planning for Practice Court Size
Teams or individual players often need a dedicated practice space. A half court is perfect for this. It allows players to focus on specific skills. They can work on shooting, dribbling, and defense. They do not need to run the full length of a court.
* Shooting Drills: Players can work on free throws and three-point shots.
* Dribbling Drills: They can practice ball handling in tight spaces.
* Defensive Drills: Players can learn to guard others in a smaller area.
* Small-sided Games: 3-on-3 games are great for teaching team play. They also improve fitness.
Having the right practice court size means better training. It helps players get better faster.
Event Planning and Space Needs
Event organizers also need to know court sizes. Maybe they are hosting a basketball clinic. Or a small tournament. Knowing the half court area calculation helps in choosing a venue. It ensures there is enough space for players and spectators. For example, setting up multiple half courts in a large gym. Or finding a park with enough flat space. This knowledge is key for success.
Converting Half Court to Square Meters
While square feet is common in the US, many other countries use square meters. It is good to know how to convert between the two. This makes the information useful worldwide.
Easy Conversion Steps
One square foot is equal to about 0.092903 square meters.
To convert square feet to square meters, you multiply the square feet by this number.
* Formula: Square Meters = Square Feet * 0.092903
Let’s look at the common half court sizes again:
* NBA/NCAA Half Court (2,350 sq ft):
* 2,350 sq ft * 0.092903 sq m/sq ft = 218.32 square meters.
* High School Half Court (2,100 sq ft):
* 2,100 sq ft * 0.092903 sq m/sq ft = 195.10 square meters.
* Youth Half Court (1,554 sq ft):
* 1,554 sq ft * 0.092903 sq m/sq ft = 144.37 square meters.
These numbers give a clear picture of the space needed in metric units. This is useful for international projects. It is also good for people who use the metric system.
Table of Common Half Court Sizes in Meters
This table shows the different half court sizes. It includes both square feet and square meters.
| Court Type | Full Court Length (ft) | Full Court Width (ft) | Full Court Area (sq ft) | Half Court Area (sq ft) | Half Court Area (sq m) |
|---|---|---|---|---|---|
| NBA / NCAA Regulation | 94 | 50 | 4,700 | 2,350 | 218.32 |
| Common High School | 84 | 50 | 4,200 | 2,100 | 195.10 |
| Youth / Junior High | 74 | 42 | 3,108 | 1,554 | 144.37 |
This table makes it easy to compare sizes. It helps in quickly finding the right numbers.
Maximizing Your Half Court Space
If you are building a half court, think about how to use the space well. A good design makes the court more fun and useful.
Smart Layout Ideas
- Hoop Placement: Place the hoop so there is enough space behind the baseline. This allows for clear out-of-bounds play.
- Lighting: Good lighting is key for evening play. Think about LED lights. They use less power.
- Fencing: If the court is near a street or other property, put up a fence. This keeps balls from rolling away.
- Seating: Add a bench or two for players to rest. This makes the court more comfortable.
- Storage: A small storage box for basketballs and other gear is helpful.
These small additions make a big difference. They turn a simple court into a great play area.
Picking the Right Materials
The surface of your half court is very important. It affects play. It also affects how long the court lasts.
* Asphalt: This is a common and affordable base. It is good for outdoor courts. It needs a top coating.
* Concrete: Concrete is more durable than asphalt. It costs more. It is a very strong surface.
* Sport Tiles: These are plastic tiles that interlock. They are good for outdoor use. They help with drainage. They also offer some cushioning.
* Acrylic Coatings: These are applied over asphalt or concrete. They provide a smooth, colorful surface. They also protect the court.
* Indoor Surfaces: For indoor courts, wood (maple is common) is typical. It offers excellent bounce. It also reduces impact on players’ joints.
Choosing the right material makes your court last longer. It also makes playing on it more enjoyable.
Common Questions About Half Court Size
Here are some frequent questions about basketball court sizes.
Q1: What is the most common half court size for home use?
A1: The most common half court size for home use is often based on the high school dimensions, which is about 2,100 square feet (84 feet long by 25 feet wide). However, many aspiring players might try to fit an NBA-sized half court if they have the space, which is 2,350 square feet. This offers more room.
Q2: Can a full 3-on-3 game be played on a half court?
A2: Yes, a full 3-on-3 game is perfectly suited for a half court. This format of basketball is played on one half of a regulation court. It involves two teams of three players each. The game promotes quick decisions. It also makes players better at individual skills.
Q3: Does the three-point line distance affect the half court’s overall size?
A3: No, the three-point line distance does not change the half court’s overall area. The half court’s size is set by its length and width. The three-point line is just a mark on the court. It changes where players stand to shoot for three points. But it does not change the total square footage of the court itself.
Q4: Is there a minimum size for a practice court?
A4: There is no strict “minimum” size set by official rules for a practice court. However, for effective practice, you need enough space to shoot, dribble, and move. A youth half court size of about 1,554 square feet provides a decent area. Smaller spaces can still be used for drills. But they might limit full-speed movement or 3-on-3 play.
Q5: How much space is needed around the half court for safety?
A5: It is wise to add extra space around the court’s official lines. For safety, allow at least 3-5 feet of clear space around the sidelines and baseline. This gives players room to run out of bounds safely. It prevents them from running into walls or fences. This means your total space needed might be larger than just the half court dimensions.
Knowing the square footage of half a basketball court is very helpful. It allows for better planning, construction, and use of space. Whether for serious play, casual games, or just practice, the right size makes all the difference.
