About the Basketball Court Diagrams
To the right you will find basketball court dimension diagrams for regulation NBA, college (NCAA), high school, junior high (jr. high) and other youth leagues. The official measurements can be used as reference for boundary lines, free throw (FT) lines, three point (3-point) lines and other perimeter sizes. Figure out how long different basketball court sizes should be according to regulation specifications.
College 3-Point Line Moving Out
All men's college 3-point lines moved out one foot from 19-9 to 20-9 in the 2008-2009 season. The arc will remain a true arc unlike the NBA 3-point line which is cut off on each side. Women's and high school 3-point lines will remain the same (19-9). There are two separate lines of contrasting color on most courts to account for the unchanged Women's 3-Point line. We have compiled the links below of press releases and analysis of what effect the expansion will have on the game.

Basketball Court Dimension Variations
The biggest variations between basketball court dimension specifications are between the American and international basketball courts. There are also big differences between the NBA and all other American court dimensions such as college and high school measurements. The NBA three point line is further out. The key is also much wider. Also, the actual length of the basketball court itself is longer.
Making the Basketball Court Regulation Sized
When choosing a basketball goal to go on your basketball court the overhang is an important aspect of the system to consider. The regulation distance from the baseline to the front of the backboard is 4 feet. Most basketball systems available, at most, have a 4 foot extension arm (not overhang). This means that if you want an official perimeter baseline boundary (such that the basketball pole is not sitting on the base line), you need a basketball hoop system with a 5 foot extension arm.
What Size Basketball Court Do I Need?
Most two car driveways cannot fit much more than a free throw line although some larger driveways including 3 and 4 car driveways have enough room for a full college or NBA three point (3-point) line. If you are pouring a dedicated basketball court in your backyard (how to do it yourself, basketball court building companies), you can make it as large as you'd like. Depending on your budget, you can have a full NBA sized basketball court to a minimal half court.
