Basketball court dimensions and sizes have evolved over the years to reflect the level of play, location, and the value attached to the game. However, most times, it is the level of play that determines the size and court dimensions.

To make things more comprehensive, we have decided to explain the various sizes and dimensions with illustrations and diagrams for various leagues such as the NCAA, NBA, WNBA, and FIBA.

Basketball Court Sizes

The basketball court size depends on the type of court measured, although there are standards. Factors like the age range, budgets, and other constraints involved are considered when those building courts are planning.

Basketball Court Dimensions

If we are to go by regulation, a basketball court’s dimensions are measured at 94×50 feet in length and width, respectively.

Court sizes vary according to the level and league playing; for example, the court dimensions for the NBA, WNBA, and college measures the standard 94×50 feet in length and width, respectively. Also, bear in mind that the free-throw lane, which is usually marked with paint, is usually 16 feet across while the backboard area, that is, the foul line, is at 15 feet and 2 inches in width.

It is also worthy to note that the Basketball courts of the International Basketball Federation (FIBA) and the Olympic basketball courts are 91.9×49.3 (28x15m), which is slightly smaller in size.

Basketball Court Dimensions for High Schools

High School and Junior High School Basketball gyms are measured at 84×50 feet in length and width, respectively, with the court’s markings reflecting the dimensions.

The court length for those at a lower level of play other than college or professional level is 10 feet shorter, which means it is 74×50 feet in length and width, respectively.

Hoop Heights & Sizes for Basketball Courts

The distance between the gym floor and the rim is 10 feet. This is the standard for high schools (junior and senior), NCAA, NBA, WNBA, and FIBA basketball ball courts. In some situations, when youngsters are playing, the rim height could be lowered to 8 or 9 feet to accommodate their size.

Although these days, we see children playing in courts with the 10 feet rim. It is generally believed that if children could adapt to the standard, they would become more comfortable when they play as adults. This claim is up for debate, though.
