While college courts are 94' long, high school courts are 84'. Junior high courts are even smaller at 74' and play with a width of 42'. The other primary difference is high school courts generally do not have a restricted arc under the basket. The three-point line is 19' 9" on both high school and junior high basketball courts.
A key basketball court dimension for installation purposes is the distance from the baseline to the face of the backboard. In a setting where sanction play will occur the dimension from the baseline to the face of the backboard will be 4'.
High school and NCAA basketball courts tend to be the same dimensions. The 3-point line, free throw line and other general dimensions are the same. If you are building your own backyard or indoor basketball court we recommend that you use the measurements shown above.

An NCAA basketball court will be 94 feet in length by 50 wide, with the half court line at 47 feet, directly in the center of the court. The free throw line is 19 feet from the edge of the court and 15 feet from the front of the backboard. The 3 point shooting line is 22.15′ from the center of the hoop.
As per the FIBA norms, the length of the basketball court is 91.85 ft (28 m), while its breadth is 49.21 ft (15 m). The height of the rim or hoop is the same as in NBA, i.e., 10 ft (3.5 m). In fact, the height of the hoop is same irrespective of the measurements in senior level basketball.
22 ft (6.71 m) to 23.75 ft (7.24 m): NBA. The NBA adopted the three-point line at the start of the 1979–80 season. This is of variable distance, ranging from 22 feet (6.7 m) in the corners to 23.75 feet (7.24 m) behind the top of the key.
The court measures 94 feet long by 50 feet wide for NBA court dimensions and WNBA and college. Note the paint area – the free throw lane – is 16 feet across. The foul line is 15 feet from the face of the backboard and 2 inches wide. International Basketball Federation (FIBA) and Olympic basketball courts call for the court to be slightly smaller at 91.9 feet by 49.2 feet.
