A standard basketball court measures 4,700 square feet in the NBA and NCAA because it is 94 feet long and 50 feet wide. However, the total square footage depends on the level of play. A typical U.S. high school basketball court measures 84 feet by 50 feet, covering 4,200 square feet, while an international FIBA court measures approximately 4,521 square feet.
Knowing the size of a basketball court is useful when planning a gymnasium, building an outdoor court, estimating flooring costs, or determining how much space is needed for basketball practice. The playing surface is also different from the larger area required for a complete court facility, which needs additional space around the sidelines and baselines.
In this guide, you will learn the square footage of NBA, college, high school, and international basketball courts, how to calculate their areas, and how much space you may need for a half court or backyard basketball court.
How Many Square Feet Is a Basketball Court?
A full-size basketball court typically covers 4,200 to 4,700 square feet in common U.S. school and professional formats. International courts have slightly different dimensions.
Here is a quick comparison of standard court sizes:
| Basketball court type | Length | Width | Total area |
|---|---|---|---|
| NBA court | 94 ft | 50 ft | 4,700 sq. ft. |
| NCAA college court | 94 ft | 50 ft | 4,700 sq. ft. |
| U.S. high school court | 84 ft | 50 ft | 4,200 sq. ft. |
| FIBA international court | 91.86 ft | 49.21 ft | Approximately 4,521 sq. ft. |
| NBA half court | 47 ft | 50 ft | 2,350 sq. ft. |
| High school half court | 42 ft | 50 ft | 2,100 sq. ft. |
These figures describe the rectangular playing surface, not the total gymnasium or surrounding safety area. Actual court dimensions can vary in recreational facilities and older school gyms.
How to Calculate the Square Footage of a Basketball Court
Calculating the area of a basketball court is simple because the playing surface is rectangular.
Use this formula:
Square footage = Length × Width
Measure the court’s length and width in feet, then multiply the two measurements.
Example 1: NBA Basketball Court
An NBA court measures 94 feet long and 50 feet wide.
Calculation:
94 × 50 = 4,700 square feet
Therefore, an NBA basketball court covers 4,700 square feet.
Example 2: High School Basketball Court
A typical U.S. high school court measures 84 feet long and 50 feet wide.
Calculation:
84 × 50 = 4,200 square feet
Therefore, a high school basketball court covers 4,200 square feet.
Example 3: Backyard Basketball Court
Suppose you want to build a rectangular backyard court measuring 30 feet by 50 feet.
Calculation:
30 × 50 = 1,500 square feet
Your backyard basketball court would cover 1,500 square feet. This is smaller than a regulation full court, but it may be suitable for shooting practice and recreational play.
How Many Square Feet Is an NBA Basketball Court?
An NBA basketball court covers 4,700 square feet, with regulation playing dimensions of 94 feet long by 50 feet wide. These dimensions are specified in the official NBA court rules.
The court includes several important markings, such as the center circle, free-throw lanes, three-point lines, and restricted areas around the baskets.
The 4,700-square-foot figure includes the rectangular playing surface within the court boundaries. It does not include the additional floor space needed around the court for player movement, officials, benches, spectators, and other arena functions.
NBA Court Dimensions in Other Units
The same court can be expressed in several different units.
| Measurement | NBA court |
|---|---|
| Length | 94 feet |
| Width | 50 feet |
| Area | 4,700 square feet |
| Area in square yards | Approximately 522.22 sq. yd. |
| Area in square meters | Approximately 436.64 sq. m. |
| Length in meters | 28.65 m |
| Width in meters | 15.24 m |
To convert square feet into square yards, divide by 9 because one square yard contains 9 square feet.
4,700 ÷ 9 = 522.22 square yards.
How Many Square Feet Is a College Basketball Court?
A standard NCAA college basketball court measures 94 feet long by 50 feet wide, giving it an area of 4,700 square feet.
The overall dimensions are the same as those of an NBA court, although some court markings differ between professional and college basketball.
College courts are designed for competitive play, so their floor layouts must accommodate the appropriate three-point lines, free-throw areas, center circle, and other markings required by the governing rules.
When estimating the flooring for a college court, remember that the court’s playing area is only part of the gymnasium. The building may need additional room for seating, team benches, walkways, equipment, and safety clearances.
How Many Square Feet Is a High School Basketball Court?
A typical U.S. high school basketball court measures 84 feet long by 50 feet wide.
Calculation:
84 × 50 = 4,200 square feet
Therefore, a standard high school court covers 4,200 square feet.
High school courts are generally shorter than NBA and NCAA courts, although facility dimensions can vary. Some schools have older gyms or layouts with different dimensions.
For official school-court guidance, consult the National Federation of State High School Associations (NFHS) basketball resources.
High School Court Measurements
| Measurement | Typical high school court |
|---|---|
| Length | 84 feet |
| Width | 50 feet |
| Total area | 4,200 square feet |
| Area in square yards | Approximately 466.67 sq. yd. |
| Area in square meters | Approximately 390.19 sq. m. |
If you are planning a school gym, verify the intended competition level and local requirements before finalizing the court dimensions.
How Many Square Feet Is an International Basketball Court?
International basketball competitions governed by FIBA use a court measuring 28 meters long by 15 meters wide.
To calculate the area:
28 × 15 = 420 square meters
One square meter equals approximately 10.7639 square feet.
420 × 10.7639 ≈ 4,520.84 square feet
Therefore, an international FIBA basketball court covers approximately 4,521 square feet.
This is slightly smaller than the 4,700-square-foot NBA and NCAA court.
When building an international-standard court, use the official metric dimensions rather than simply copying the U.S. measurements.
How Many Square Feet Is a Basketball Half Court?
A basketball half court is approximately half the length of a full court while retaining the full width.
The exact area depends on the court format.
| Half-court type | Length | Width | Total area |
|---|---|---|---|
| NBA or NCAA half court | 47 ft | 50 ft | 2,350 sq. ft. |
| High school half court | 42 ft | 50 ft | 2,100 sq. ft. |
| FIBA half court | 14 m | 15 m | Approximately 2,260 sq. ft. |
For an NBA half court:
47 × 50 = 2,350 square feet
A 2,350-square-foot half court can provide space for shooting practice, individual training, and recreational games. However, the exact layout should match the type of basketball activity you plan to support.
A half court also needs appropriate room around the boundaries if players will be running, jumping, or chasing rebounds.
How Much Space Do You Need for a Full Basketball Court?
The playing surface of an NBA court measures 94 by 50 feet, but a facility generally needs additional space around the playing area.
This extra space can provide clearance for players, officials, benches, equipment, and safe movement outside the boundary lines.
For example, suppose you allow 10 feet of extra space on every side of an NBA court.
New length:
94 + 10 + 10 = 114 feet
New width:
50 + 10 + 10 = 70 feet
Total rectangular footprint:
114 × 70 = 7,980 square feet
Under this example, the overall area would be 7,980 square feet, including the court and the surrounding 10-foot margins.
This is a planning example, not a universal facility standard. The required clearance depends on the governing rules, facility design, local regulations, and the intended level of play.
For a gymnasium, you must also account for walls, entrances, seating, storage, and any other building requirements.
How Many Square Feet of Flooring Do You Need for a Basketball Court?
If you are installing a basketball court floor, the playing surface area provides a starting point for estimating materials.
For example, an NBA court has an area of 4,700 square feet. If you add a hypothetical 5% allowance for cutting, fitting, and waste:
4,700 × 0.05 = 235 square feet
Add the allowance to the court area:
4,700 + 235 = 4,935 square feet
You would estimate approximately 4,935 square feet of material under this example.
However, the appropriate allowance depends on the flooring product, installation pattern, court markings, and manufacturer’s guidance. Some flooring systems are installed differently from standard tiles, so confirm the material quantity with your supplier or installer.
How Much Flooring Is Needed for a High School Court?
A high school court covers 4,200 square feet.
Using the same hypothetical 5% allowance:
4,200 × 1.05 = 4,410 square feet
This gives an initial estimate of 4,410 square feet of material, before considering the exact installation plan.
How Much Concrete Is Needed for a Basketball Court?
If you are building an outdoor basketball court, you may need a concrete slab beneath the playing surface. The concrete quantity depends on the court’s area and the slab thickness.
Use this formula:
Concrete volume in cubic feet = Area in square feet × Thickness in feet
One cubic yard contains 27 cubic feet.
Example: A 4,700-Square-Foot Court With a 4-Inch Slab
First, convert 4 inches into feet:
4 ÷ 12 = 0.333 feet
Calculate the concrete volume:
4,700 × 0.333 ≈ 1,566.7 cubic feet
Convert cubic feet into cubic yards:
1,566.7 ÷ 27 ≈ 58.03 cubic yards
A 4,700-square-foot surface with a uniform 4-inch thickness would require approximately 58.03 cubic yards of concrete, before accounting for waste, thickened edges, drainage details, or other design requirements.
This is only a mathematical example. Outdoor sports courts need appropriate base preparation, drainage, reinforcement, joints, and a slab design suitable for the site and intended use. Have the structure specified by a qualified professional.
How Much Does a Basketball Court Cost Based on Square Footage?
The cost of building a basketball court varies substantially depending on the location, materials, site preparation, labor, drainage, lighting, and whether the court is indoors or outdoors.
Square footage helps you estimate costs once you know the local price per square foot.
Use this formula:
Estimated cost = Total area × Cost per square foot
For example, if a contractor quotes $10 per square foot for a particular project and the playing surface covers 4,700 square feet:
4,700 × $10 = $47,000
The estimated cost would be $47,000 under that hypothetical rate.
This example is for calculation purposes only, not a current market quotation. The actual cost may differ significantly, especially if the project includes excavation, a concrete base, specialized sports flooring, fencing, lighting, or a roofed facility.
