If you’re planning to build a basketball court, comparing gym sizes, estimating flooring requirements, or simply wondering how much space basketball requires, you may ask: how many square feet is a basketball court?
The answer depends on the level of basketball being played. NBA, college, high school, and international FIBA courts aren’t all exactly the same size.
An NBA basketball court is 94 feet long and 50 feet wide, giving it a playing area of:
4,700 square feet
The calculation is simple:
94 feet × 50 feet = 4,700 square feet
The NBA confirms that its court measures 94 feet long by 50 feet wide.
International FIBA courts are smaller. A standard FIBA playing court measures 28 meters by 15 meters, which is approximately 91.86 feet by 49.21 feet. That produces approximately 4,520.8 square feet of playing area.
So, if you’re looking for a quick answer, an official full-size basketball court generally covers about 4,500–4,700 square feet, depending on the governing organization.
Quick Answer
How many square feet is a basketball court?
It depends on the type of court:
| Basketball Court Type | Dimensions | Approx. Square Feet |
|---|---|---|
| NBA | 94 × 50 ft | 4,700 sq ft |
| FIBA | 28 × 15 m | 4,521 sq ft |
| High School | 84 × 50 ft* | 4,200 sq ft |
| Typical recreational court | Varies | Varies |
*High-school dimensions can be subject to the applicable rules and facility standards.
The most commonly referenced professional U.S. court is the NBA court, which is 4,700 square feet.
How Do You Calculate the Square Feet of a Basketball Court?
A basketball court is essentially a rectangle, so you can calculate its area using:
Area = Length × Width
For an NBA court:
Area = 94 × 50
Area = 4,700 square feet
Therefore:
An NBA basketball court is 4,700 square feet.
The same formula works for other court sizes.
For example, if a court measures 84 feet by 50 feet:
84 × 50 = 4,200 square feet
So the playing surface would be 4,200 square feet.
How Many Square Feet Is an NBA Basketball Court?
An official NBA basketball court measures:
- 94 feet long
- 50 feet wide
The NBA’s own specifications identify the court as 94 feet by 50 feet.
Multiply the two dimensions:
94 × 50 = 4,700
NBA basketball court = 4,700 square feet
This refers to the rectangular playing court itself, not the entire arena floor, seating area, benches, scorer’s table, aisles, or other surrounding space.
How Many Square Feet Is a FIBA Basketball Court?
FIBA, the international governing body for basketball, uses a court measuring:
28 meters × 15 meters
FIBA’s venue guide identifies the inner playing area as 28 meters long and 15 meters wide.
The area in metric units is:
28 × 15 = 420 square meters
To convert square meters to square feet:
420 × 10.7639 ≈ 4,520.8 square feet
Therefore:
A FIBA basketball court is approximately 4,521 square feet.
This is smaller than the NBA court.
NBA:
4,700 sq ft
FIBA:
≈4,521 sq ft
The difference is approximately:
4,700 − 4,520.8 = 179.2 square feet
NBA vs. FIBA Basketball Court Size
Although the two courts look similar, there is a measurable difference.
| Feature | NBA | FIBA |
|---|---|---|
| Length | 94 ft | 28 m ≈ 91.86 ft |
| Width | 50 ft | 15 m ≈ 49.21 ft |
| Area | 4,700 sq ft | ≈4,521 sq ft |
| Difference | — | ≈179 sq ft smaller |
The NBA itself notes that international basketball uses a smaller court than the NBA’s 94-by-50-foot court.
How Many Square Feet Is a College Basketball Court?
College basketball uses a court that is generally 94 feet long and 50 feet wide for NCAA play.
That produces:
94 × 50 = 4,700 square feet
College basketball court = 4,700 square feet
The NCAA provides current basketball rules and full-court diagrams through its official rules resources.
Therefore, for a full-size NCAA court, you can use the same basic area calculation as an NBA court.
How Many Square Feet Is a High School Basketball Court?
A common full-size U.S. high school basketball court measures approximately:
- 84 feet long
- 50 feet wide
The area is:
84 × 50 = 4,200 square feet
High school basketball court = approximately 4,200 square feet
The National Federation of State High School Associations (NFHS) maintains the rules and basketball court resources for U.S. high school competition.
Because school facilities and local rules can vary, check the applicable NFHS/state specifications when planning an official court.
Basketball Court Square Footage Comparison
Here’s a useful comparison:
| Court | Length | Width | Square Feet |
|---|---|---|---|
| NBA | 94 ft | 50 ft | 4,700 |
| NCAA | 94 ft | 50 ft | 4,700 |
| FIBA | 91.86 ft | 49.21 ft | ≈4,521 |
| High School | 84 ft | 50 ft | 4,200 |
| Half court, NBA dimensions | 47 ft | 50 ft | 2,350 |
These figures describe the rectangular playing surface.
How Many Square Feet Is Half a Basketball Court?
If you divide an NBA court in half lengthwise:
94 ÷ 2 = 47 feet
A half court would therefore measure approximately:
47 × 50 feet
Calculate:
47 × 50 = 2,350 square feet
An NBA-style half court is approximately 2,350 square feet.
This doesn’t necessarily mean a home or recreational half court needs exactly 2,350 square feet of total property space. You also need room around the playing area for safety and movement.
How Many Square Feet Does a Basketball Court Cover?
If you’re asking about the actual playing surface, the answer depends on the court’s dimensions.
For example:
NBA
94 × 50 = 4,700 sq ft
High school
84 × 50 = 4,200 sq ft
FIBA
28 × 15 = 420 sq m ≈ 4,521 sq ft
Therefore, a standard full-size basketball court generally occupies somewhere around 4,200 to 4,700 square feet of playing surface, depending on the standard being followed.
How Much Space Do You Need for a Basketball Court?
The playing surface isn’t the only space required for a functional basketball facility.
A regulation court needs additional space around the boundaries for:
- Player safety
- Referees
- Benches
- Scorer’s table
- Spectators
- Equipment
- Walls and structural elements
- Access routes
For example, FIBA’s venue guidance calls for a minimum 2-meter surrounding boundary area around the 28-by-15-meter inner playing area for the relevant facility configuration.
The NBA rule diagram also specifies minimum clearances around the court.
Therefore, don’t assume a 4,700-square-foot room is automatically large enough to build a regulation NBA court.
Basketball Court Area vs. Total Gym Space
This distinction is important when planning a gymnasium.
Court area
The actual rectangular playing surface.
For an NBA court:
4,700 square feet
Total facility area
The court plus:
- Run-off space
- Seating
- Team benches
- Locker rooms
- Storage
- Restrooms
- Hallways
- Mechanical areas
- Scoreboard areas
The total building can therefore be much larger than 4,700 square feet.
If you’re designing a facility, use the applicable governing body’s facility requirements rather than simply multiplying 94 by 50.
How Many Square Feet of Flooring Does a Basketball Court Need?
If you’re purchasing flooring for only the rectangular playing surface, an NBA court has:
4,700 square feet
However, you normally shouldn’t order exactly 4,700 square feet of flooring without considering:
- Installation waste
- Cutting
- Court markings
- Flooring layout
- Expansion requirements
- Manufacturer recommendations
For a real construction project, the flooring supplier or contractor should determine the final quantity.
How Many Acres Is a Basketball Court?
An NBA court covers 4,700 square feet.
Since:
1 acre = 43,560 square feet
divide:
4,700 ÷ 43,560 ≈ 0.1079 acres
Therefore:
An NBA basketball court is approximately 0.108 acre.
In other words, the playing surface is slightly more than one-tenth of an acre.
How Many Basketball Courts Fit in an Acre?
Using an NBA court:
43,560 ÷ 4,700 ≈ 9.27
So, based strictly on rectangular playing-surface area:
About 9.27 NBA courts fit into one acre.
However, you could not realistically construct 9 complete courts on one acre because each court requires surrounding clearance and other facility space.
This calculation is useful only for comparing areas.
How Many Square Meters Is an NBA Basketball Court?
An NBA court measures:
94 feet × 50 feet
The area is:
4,700 square feet
To convert square feet to square meters:
4,700 × 0.092903 ≈ 436.64 square meters
Therefore:
An NBA basketball court is approximately 436.6 square meters.
For comparison, a FIBA court is exactly:
28 × 15 = 420 square meters
So the NBA court is approximately 16.6 square meters larger.
How Many Square Feet Is a Basketball Court in a School?
School basketball courts can vary.
A full-size high school court is commonly around:
4,200 square feet
based on 84 × 50 feet.
College courts are generally:
4,700 square feet
based on 94 × 50 feet.
Some school gyms may have courts that don’t exactly match competition dimensions, especially when the facility is designed for recreational use or multiple sports.
How Big Is a Basketball Court Compared With a Tennis Court?
A basketball court is substantially larger than a standard tennis singles playing area but has different dimensions and purposes.
A full NBA basketball court is:
4,700 square feet
A regulation tennis court, including doubles playing lines, is approximately:
78 × 36 = 2,808 square feet
However, these are only the marked playing areas. Safety clearances around both courts require additional space.
How Big Is a Basketball Court Compared With a Football Field?
A full American football field, including end zones, is:
120 yards × 53⅓ yards
That’s much larger than a basketball court.
An NBA basketball court is:
94 × 50 = 4,700 square feet
This comparison helps explain why basketball can be played in relatively compact indoor facilities while football requires a much larger playing area.
What Are the Main Dimensions of an NBA Basketball Court?
Besides the overall 94-by-50-foot dimensions, an NBA court contains numerous specific markings.
These include:
- Center circle
- Half-court line
- Free-throw lanes
- Free-throw lines
- Three-point arc
- Restricted area
- Baselines
- Sidelines
- Team bench areas
The NBA’s current rulebook provides the official court diagram and measurements.
The NBA also lists the free-throw line as 15 feet from the rim and provides specifications for the three-point arc.
Does the Basketball Hoop Change the Square Footage?
No.
When calculating the area of the rectangular court, you simply use:
Length × Width
The basket, backboard, painted lines, free-throw circle, three-point arc, and other markings don’t change the basic rectangular area calculation.
The hoop is part of the equipment installed around the playing surface.
How to Calculate the Square Footage of Any Basketball Court
You don’t have to memorize every court size.
If you know the length and width, use:
Square Feet = Length × Width
For a 90-foot × 50-foot court:
90 × 50 = 4,500 square feet
For an 80-foot × 40-foot court:
80 × 40 = 3,200 square feet
For a 94-foot × 50-foot court:
94 × 50 = 4,700 square feet
This makes it easy to calculate the area of a custom recreational court.
Common Basketball Court Size Mistakes
Mistake 1: Assuming Every Court Is 94 × 50 Feet
That’s the NBA size, but not every basketball court follows NBA dimensions.
FIBA, high school, youth, and recreational courts can be different.
Mistake 2: Confusing Playing Area With Facility Area
A 4,700-square-foot court doesn’t mean you need exactly a 4,700-square-foot building.
You’ll need additional clearance and facility space.
Mistake 3: Forgetting Unit Conversion
FIBA dimensions are given in meters, so you must convert square meters to square feet when comparing them with U.S. measurements.
Mistake 4: Measuring From the Wrong Boundary
When calculating a regulation court, use the specified playing-court dimensions rather than an unrelated wall-to-wall measurement.
