There are 3 different dimensions of a high school basketball court. The dimensions of the court can be expressed as length, width, and height. The length of the court is the distance from the baseline to baseline. The width of the court is the distance between the sidelines. The height of the court is often measured from the floor to the top of the backboard.
A few of the lesser-known elements of a basketball court are below:
The Division Line: Line that marks the center of the court
Tip-Off Circle: has a six-foot radius
Restricted Area: High school basketball courts do not have any restricted area under the basket, since that rule doesn’t exist in high school basketball.
Maintaining Your High School Basketball Court Floor
Most high school basketball courts are made of wood and can be a large investment for a school district. Once you have installed your wood basketball court is important to do daily maintenance. Here is a list of three things that should be done daily to maintain your basketball court and keep it safe and looking good.
Matting
The use of walk-off mats where there are outside entrances directly to the gym is the first defense in preventative maintenance. Select a mat that will trap dirt and absorb moisture brought in by foot traffic. More than 75% of soil in any building is tracked in from outside. Also, keep sidewalks clean to reduce soil and dust in the building.
Dust Mopping
An essential element of preventative maintenance of wood sports flooring is dust-mopping daily.
The least expensive and most important tool in floor care is the dust mop. A mop that has been treated with Super
Hil-Tone, Hil-Mist, or EP Dust Mop Treatment will remove dirt and grit that can abrasively wear away the gloss and
protective finish of the floor.
Treat the dust mop by following the label directions. Brush or vacuum the mop after daily use and re-treat the mop with dressing and store it properly for the next day’s use.
Spot Mopping and Damp Mopping
Preventative maintenance of wood sports flooring includes the routine removal of spills and soils that daily dust
mopping does not remove. It is important to remove spills as soon as possible to prevent slips and falls.
