The standard height of an actual basketball hoop is 10 feet. Every basketball league and the professional game tends to follow this height as it has become the symbol or the standard value for basketball hoops. As I stated earlier, this basketball hoop height is the standard height, and you might have to go with another height for the players who are younger or shorter.
We suggest the height of the hoop per age bracket as follows: Ages 5 – 7 (Grade: K – 2nd): 6 – 7 Feet Ages 8 – 9 (Grade: 3rd – 4th): 8 Feet Age 10 (Grade: 5th): 8 Feet Ages 11+ (Grade: 6th+): 10 Feet [Regulation Height]
The NBA 3-point line is 23.75 feet from the hoop, 22 feet in the corners. The FIBA 3-point line is 22.15 feet from the hoop, 21.65 feet in the corners. The WNBA uses the same 3-point line as FIBA.
Since its inception, the game of basketball has always required that the basket rim height be set at 10 feet. In 1891 in Springfield, Massachusetts, Canadian James Naismith invented a game called "basket ball" as part of a Young Men’s Christian Association (YMCA) training school class assignment and drafted a brief set of rules of how the game was to be played.
Basketball Backboard Dimensions. The regulation dimensions of a basketball backboard are 72 inches wide by 42 inches tall with an inner square to help players aim for the backboard measuring 24 inches wide by 18 inches tall. This translates to a backboard 6 feet wide by 3.5 feet tall for regulation basketball courts.
If you have a boy or a girl younger than four, it’s probably best to start with 3-5 feet. These basketball hoop heights may be a bit too high, but it’s not going to be a problem since, at that age, someone’s already always there to catch him or her fall.
The recommended heights for basketball goals are the same for male and female. For professional basketball all the way down to 6th grade the goal is 10-feet. For 5th grade, the goal should be placed at 9-feet. And for the 3rd and 4th grade(8 to 10 years-old) 8-foot rims. Lastly 6-foot rims for kindergarten, 1st, and 2nd grades.
The height of an NBA hoop — and most regulation-sized hoops — is 10 feet off the ground. This can vary for some youth basketball leagues who may use adjustable rims or hang a makeshift backboard and basket on the front of a regular hoop. The height of the hoop is so ingrained in the sport, it’s difficult to imagine it ever changing.
