How Big Is An NBA Basketball Court? & Equipment

youtube channel


The NBA court’s dimension has gone through some changes throughout the years. For good reason, with 7-foot giants roaming the courts now and athletic freaks dunking from everywhere on the court, the playing field has to be big enough to accommodate these talent stars. But just how big?

How big is an NBA basketball court? An NBA basketball court measures 94 feet in length (28.9 meters) and 50 feet wide (15.38 meters). If you think in terms of football to the 30-yard line(length) by 15-yard line (width). This is longer than a high school basketball court by 10 feet.

Interestingly enough on the TV, it doesn’t appear to be all that big, but as viewers, it is hard to grasp the size of the players and the court from the screen. We will take a look at the dimensions of the court and equipment used in the game and see how it compares to each of the NBA.


Basketball Court & Equipment Measurements

So now that we know the basketball court is 94 feet by 50 feet, what about the free-throw line, 3-point line and the height of the rim. I will go over the most common measurements that people are curious to know. In the chart provided measurements of the court lines and equipment.


Court Lines Size Compared To
Court 54 Feet Length x 50 Feet Wide 30 Yards (L)  x 15 Yards (W)
Free-Throw Line 15 Feet Length x 12 Feet Wide Can park a mid-size car in the Key
Three-Point Line 23 Feet and 9 Inches. Half the size of a telephone pole.
Three-Point line Sideline 22 Feet 3 Times as tall as Shaq


Equipment such as basketballs, rim height and such will be covered also. If your interested in more information click the links in blue in the table chart for more information on that topic.


Equipment  Size
Basketball Rim Height 10 Feet
Diameter Of The Rim 18 Inches
Backboard 6 Feet x 3 1/2 Feet (LxW)
Basketball 29 Inches Around


NBA Court Comparisons

Keep in mind not every high school court is built the same I have seen courts much smaller and played against schools when coaching that use presses to their advantage on smaller courts. You will see why I put an approximation.


League  Dimensions In Feet Length X Width
NBA 94 ft x 50 ft
FIBA 92 ft x 49 ft
WNBA 94 ft x 50 ft
NCAA 94 ft x 50 ft
High School 85 ft x 50 ft
Jr. High 70 to 75 ft x 40 to 45 ft


Three-Point Line Comparisons

From college to the NBA is quite the jump and no wonder players will struggle the first couple years in the NBA to shoot well from the three-point line. It is an extra foot which makes a huge difference. Again Fiba all the way down the list should just make one universal rule for distance from the three, it is a little annoying to me.


League  Distance 
NBA  23 ft 9 inches
FIBA 22 ft 1 inch
WNBA 22 ft 1.75 inches
NCAA 22 ft 1 inch
High School 19 ft 9 inches
Jr. High 19 ft 9 inches

Basketball Size Comparisons

The basketball used again depends on the basketball league, The NBA uses a ball by Spalding specifically for the NBA called the Spalding Official Ball of the NBA. The WNBA is called the same but with the W.

FIBA also has their own ball for their play, called the Molten BGLX Official FIBA basketball. The NCAA basketball is called the Wilson official basketball of the NCAA ball.

As far as high school and junior high, you guessed it, depends on what the league uses.


League Basketball Size In Inches
NBA 29 .5″
FIBA 29.5″
WNBA 28.5″
NCAA 29.5″
High School 29.5″
Jr. High 28.5″
