If you’ve ever watched an NBA game and wondered how large the playing surface actually is, the answer is surprisingly straightforward. An official NBA basketball court measures 94 feet long and 50 feet wide.
According to the NBA, the playing court is 50 feet wide by 94 feet long.
That means an NBA court has a total playing area of:
94 × 50 = 4,700 square feet
So, the quick answer is:
An NBA basketball court is 94 feet long and 50 feet wide.
The dimensions are standardized so NBA teams play on the same size playing surface regardless of the arena. The NBA’s official rules specify the court dimensions, while NBA educational material also identifies the standard court as 94 feet by 50 feet.

The NBA’s official court specifications confirm the 94-by-50-foot playing court and related markings.
How Long Is an NBA Basketball Court?
An NBA basketball court is:
94 feet long
This means a player running from one baseline to the opposite baseline travels 94 feet across the length of the playing court.
The NBA’s official rules specify a playing court measuring 94 feet in length.
For perspective, 94 feet equals:
- 1,128 inches
- Approximately 28.65 meters
- Approximately 31.33 yards
The 94-foot length is one of the defining dimensions of a professional NBA court.
How Wide Is an NBA Basketball Court?
An NBA basketball court is:
50 feet wide
The 50-foot width runs between the two sidelines.
In other units:
- 50 feet
- 600 inches
- Approximately 15.24 meters
- Approximately 16.67 yards
The NBA lists the court width as 50 feet inside the playing boundaries.
How Many Square Feet Is an NBA Basketball Court?
Because the court is rectangular, calculating its area is simple:
Length × Width = Area
Therefore:
94 feet × 50 feet = 4,700 square feet
An NBA basketball court contains 4,700 square feet of playing area.
This calculation refers to the playing court itself, not the surrounding seating, scorer’s table, benches, aisles, or arena floor space.
NBA documentation also gives the court dimensions as 94 feet by 50 feet.
Is an NBA Court Bigger Than a College Basketball Court?
Yes.
A standard NBA court is 94 feet long by 50 feet wide.
A standard NCAA basketball court is generally the same 94-foot length, but its overall markings and specifications can differ from the NBA. The most noticeable differences are often the three-point line and lane dimensions.
The NBA itself notes that its three-point line and other court markings differ from international and amateur basketball.
So, while the overall footprint can be similar, an NBA court should not be assumed to have identical markings to every other basketball court.
NBA Court vs. FIBA Court
The international basketball court used under FIBA rules is slightly smaller.
The NBA court measures:
94 × 50 feet
The FIBA court is approximately:
91 feet 10 inches × 49 feet 2.5 inches
NBA.com specifically identifies the international court as smaller than the NBA court.
| Feature | NBA | FIBA |
|---|---|---|
| Length | 94 ft | About 91 ft 10 in |
| Width | 50 ft | About 49 ft 2.5 in |
| Overall footprint | Larger | Slightly smaller |
This difference can affect spacing, driving lanes, defensive positioning, and three-point shooting.
How High Is an NBA Basketball Rim?
The NBA rim is:
10 feet above the floor
This measurement is separate from the court’s 94-foot length and 50-foot width.
The NBA confirms that the rim is positioned 10 feet above the playing surface.
The 10-foot rim height has been a defining feature of regulation basketball and is one reason NBA players’ jumping ability and athleticism are so impressive.
How Far Is the NBA Free-Throw Line?
The NBA free-throw line is positioned 15 feet from the plane of the backboard according to the official rules.
This is different from saying that the line is 15 feet from the front of the court.
The free-throw lane, commonly called the key or paint, is also an important part of the court layout.
How Far Is the NBA Three-Point Line?
The NBA three-point arc is not the same distance from the basket at every location.
At the top of the arc, the distance is:
23 feet 9 inches
At the corners, the three-point line is:
22 feet
The NBA’s official court specifications identify the arc at 23 feet 9 inches and the corner distance at 22 feet.
This is why corner three-pointers are taken from a shorter distance than shots from the top of the three-point arc.
How Wide Is the NBA Lane?
The NBA lane, often called the paint or key, is:
16 feet wide
The NBA’s Jr. NBA materials explain that the NBA lane is 16 feet wide, compared with narrower amateur lanes.
The wider lane is an important part of professional basketball because it affects:
- Post play
- Rebounding
- Defensive positioning
- Driving lanes
- Help defense
- Pick-and-roll spacing
How Big Is an NBA Backboard?
The official NBA backboard measures:
6 feet wide × 3.5 feet high
The backboard is positioned behind the basket and provides the structure to which the rim is attached.
The NBA’s official rules specify a backboard measuring 6 feet horizontally and 3½ feet vertically.
The rectangular target painted on the backboard is smaller than the overall backboard.
How Big Is an NBA Basketball Rim?
The inside diameter of an NBA basket ring is:
18 inches
The rim is mounted 10 feet above the playing surface. The official NBA rules specify an 18-inch inside diameter for the basket ring.
This standardized rim size is used across NBA arenas.
NBA Court Dimensions in Inches
If you need to work with smaller measurements, you can convert the court dimensions into inches.
Since:
1 foot = 12 inches
The length is:
94 × 12 = 1,128 inches
The width is:
50 × 12 = 600 inches
Therefore:
NBA court:
- 1,128 inches long
- 600 inches wide
NBA Court Dimensions in Yards
There are three feet in one yard.
For the length:
94 ÷ 3 = 31.33 yards
For the width:
50 ÷ 3 = 16.67 yards
So an NBA court is approximately:
31.33 yards long × 16.67 yards wide
This comparison can be useful when visualizing the size of a professional basketball court.
NBA Court Dimensions in Meters
One foot equals approximately 0.3048 meters.
Therefore:
94 × 0.3048 = 28.6512 meters
And:
50 × 0.3048 = 15.24 meters
So an NBA court measures approximately:
28.65 meters × 15.24 meters
NBA sources commonly give the NBA court as approximately 28.7 by 15.2 meters.
How Much Flooring Is Needed for an NBA Court?
The playing surface alone has an area of:
94 × 50 = 4,700 square feet
Therefore, a court requires:
4,700 square feet of playing surface
However, an actual NBA arena needs considerably more floor space around the court.
Space is needed for:
- Team benches
- Scorer’s table
- Camera positions
- Officials
- Advertising
- Safety areas
- Player entrances
- Equipment
- Courtside seating
Therefore, an arena’s total basketball floor area is much larger than the 4,700-square-foot playing court.
Can You Fit an NBA Court in a Home?
For most homes, fitting a full NBA-sized court indoors would be extremely difficult.
The court itself requires:
94 × 50 feet
That’s already 4,700 square feet before adding clearance around the court.
A suitable facility would need additional space beyond the court boundaries for safe movement and equipment.
For a backyard or residential basketball court, homeowners typically use smaller dimensions instead of attempting to reproduce a full NBA court.
How Does an NBA Court Compare With a Tennis Court?
A standard tennis court has different dimensions and includes playing areas that vary depending on singles or doubles play.
An NBA basketball court is:
94 × 50 feet
Its area is:
4,700 square feet
This makes the basketball court a substantial playing surface, although the total dimensions and layout differ considerably from tennis.
How Does an NBA Court Compare With a Football Field?
An NBA basketball court is much smaller than a football field.
The NBA court has:
4,700 square feet
An American football field, excluding the end zones, is 100 yards long and 53⅓ yards wide, making its playing surface dramatically larger.
This comparison helps explain why an NBA game can fit inside a relatively small section of a large sports venue.
Why Are NBA Courts Standardized?
Standardized court dimensions provide consistency.
Every NBA team needs players to compete on essentially the same regulation playing surface.
Standardization helps ensure that:
- Distances remain consistent
- Three-point shots have standardized locations
- Free throws are taken from the same distance
- Defensive spacing remains predictable
- Coaches can design consistent plays
- Players can practice for familiar dimensions
The NBA’s official rules establish the court measurements and markings.
What Is the Difference Between the Court and the Arena Floor?
It’s important not to confuse an NBA basketball court with the entire arena floor.
The court itself is:
94 feet × 50 feet
But the arena floor surrounding it can contain:
- Courtside seats
- Team benches
- Officials’ areas
- Advertising boards
- Media areas
- Camera positions
- Walkways
Therefore, an NBA arena requires substantially more space than 4,700 square feet to host a professional game.
