About the Basketball Court Diagrams
Below 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 are moving out one foot from 19-9 to 20-9 from the center of the rim.
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. There is talk of creating a band instead of two
lines as they might be confusing. At the time of writing (6-12-07) this is not going to happen and there
will be two separate lines of contrasting color. Also, at the time of this writing there was not an
accurate diagram of the new dimensions available. This change will go into effect for the 2008-2009 season.
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.
