The game of basketball requires a certain level of skill and agility to be worthy of competition, yet the basic rules of the game and shooting baskets are something even a small child can learn. Children (and adults) of all ages have long enjoyed the games of HORSE, Around-the-World, 21 and KnockOut on driveways, in backyards and on playgrounds. Basketball doesn¡¯t discriminate based on socio-economic area, either: basketball hoops can be seen on inner-city streets and on the driveways of wealthy, gated communities. Whether on a back porch or a parking lot, the essentials needed to play basketball are always the same: a ball, a hoop, some lines, and a hard surface.
Anyone can shoot hoops over and over, but to learn how a game is played or to practice specific court shooting skills, it is necessary to draw, paint, or tape the lines on the court. Often kids will use sidewalk chalk to outline a court on their driveway or cul-de-sac. For casual play, this is fine, but making an official basketball court isn¡¯t difficult, and it can add quality to one¡¯s skills. If a driveway, backyard or playground blacktop is large enough, laying basketball court lines is a snap.
The first step is deciding on the size of the court. NBA and NCAA regulation court dimensions are 94 feet long by 50 feet wide. If there is space available, then by all means, stretch it out, but it doesn¡¯t have to be quite so long. High school regulation court dimensions are still 50 feet wide, but only 84 feet long. Middle school or junior high court dimensions measure 74 feet long and 42 feet wide. And remember, if space is still an issue, laying only a half-court can be just as effective.
The basketball backboard, whether installed on the side of a house or on a pole, should be placed 4 feet from the baseline (the outside court line behind the basket). The rim of the basket should be attached to the backboard with a 6-inch space. This means, if the diameter of the rim is 18 inches, the front of the rim will actually be 24 inches from the backboard. The top of the basket rim should be 10 feet off the ground.
The free-throw line should be placed 15 feet back from the backboard, which means it will be 13 feet from the front rim of the basket. This means that the key will measure 19 feet from the baseline behind the basket to the free-throw line, and measure 12 feet in width across the middle. The blocks set at the base of the key near the basket are 12 inches wide and 8 inches deep. The three tabs on either side, next to the blocks, measure 2 inches wide and 8 inches deep, and the width between each tab is 3 feet.
The circle above the key and the 3-point line can be tricky because they are curved. The circle above the key has a radius of 6 feet, giving it an obvious diameter of 12 feet (the width of the free-throw line), and designing it is rather straightforward. The 3-point line, however, is not a true arc. The 3-point line overlaps the circle above the key for a short distance, and then continues out into a straight line before curving back toward the baseline. Where the 3-point line meets the key circle, it measures out 21 feet (15 feet from baseline to free-throw line and then 6 feet radius of circle above the key). But as the 3-point line begins its curve, the regulation distance from the center of the basket to the line is exactly 19 feet, 9 inches. It should measure this distance all the way to the baseline.
There are several ways to place these lines on a court. If accurate measuring equipment and straight edges are available, it can be done simply with a paintbrush and can of white paint. There are companies that sell regulation basketball tape kits that are pre-cut and pre-measured for easy installation. It is similar to highway tape, so it can take lots of wear and tear. Also available from more than one manufacturer are basketball court stenciling kits. These durable stencils are simply laid out on a driveway or blacktop, taped down, and then the paint can be rolled or brushed over them. The only drawback to these is that they aren¡¯t always regulation size.
If homemade measurements and a paintbrush and straight-edge are your tools of choice, always start by doing what the kids do: first measure and lay out your court with sidewalk chalk that can easily be washed away or erased. Don¡¯t begin painting until the chalk court is just the way you want it.
Once these basketball lines are added to your own special playing place, you¡¯ll improve your game and court sense for better competition and more fun!
