Basketball Courts

What neigborhood doesn't need a basketball court? They all need one! Well once you buy your pole and backboard and you put it up, how do you go about marking the court? Even if you are only putting in a small court, you would always want to mark your free throw line and 3 point line.

Here are the dimensions to mark the court by.

Half court is well.. half the distance of the full court.. (I know, I didn't need to add that)

The free throw line is always 15 ft from the line to the backboard

The distance from the ground to the rim is 10 ft.

The 3 point arc in the NBA is 22ft to the center of the rim on the sides ( the arc starts 5 ft 3 in from the baseline, being a straight line until that point) then the curved part of the arc is 23ft. 9 in. from the center of the rim.

The 3 point arc in college and high school is 19 ft 9 in. (The straight part extends 63 in out from the baseline before the arc begins).

The key is 12 feet wide (the width of the free throw line) the backboard should extend 4 feet out over the baseline. The 12 ft wide free throw line forms the center of a circle with a 6 ft radius.

The backboard is 72 inches wide by 42 inches high and has an 18 inch diameter rim.
The inner square is marked above the rim in a rectangle of 24 inches wide and 18 inches high.

The line markings are white and 2 inches wide.

The picture below is worth a thousand words. It depicts the college and high school court dimensions.
