High School Basketball Court Dimensions Guide

It might come as a surprise, but not all basketball courts follow the same standard and are of the same size. The type and dimensions of the basketball court will usually depend on the participating players and their age. The sizes were drawn up through decades of plays after James Naismith invented the game.

The standard size of a basketball course is 94 feet by 50 feet and its shape is rectangular. Apart from this standard size, there are some arenas that are smaller, usually to accommodate plays between younger players, either in college, high school, or youth leagues.

So what are the high school basketball court dimensions? You should expect an average high school basketball court to be 84 feet long and 50 feet wide.

The actual size of the basketball court isn’t the only one that matters. The other parts of the court also have set measurements. Let’s go through these measurements in the next part of the article.

The distance between the baseline and the end line is considered the length of the court. The distance between the lines is the court’s width, while the distance between the floor and the top of the backboard gives the court’s height.

Let’s go through some other issues related to the dimensions of a court made specifically for high school basketball.

Overall Size of the Basketball Court

Most basketball courts designed for high school plays are 84 feet long by 50 feet wide. There are some fields that might be a pinch smaller at about 74 feet long by 42 feet wide, and these will usually host junior high school games.

The Foul Line

The foul line is at the same distance on all courts. It will be exactly 15 feet from the front of the backboard. Also, the distance between the baseline and the offensive line will be exactly 18 feet and 10 inches.

The Lane

The lane, which some people also called the Key, is 12 feet wide. Most courts will have the backboard four feet wide when taking into account the distance from the key to the baseline. The lane will be completed by a six-foot arc (which is a half of a circle) that will extend from the foul line away from the basket rim.

The Arc or Three-Point Line

The standards measurements for the three-point line will be identical for college and high school basketball courts. This will be 19 feet and 9 inches. An additional line that would extend for 5 feet and 3 inches will be drawn from the baseline.

The Backboard and Rim

The height of the hoop, from the ground to its top will be ten feet for all age categories. The table will have a standard size of 72 inches in width and 42 inches in height.

The basketball rim will have a standard diameter of 18 inches. The inner square on the backboard will have standard dimensions of 18 inches in height with 24 inches in width.

All lines that are drawn on the field will be 2 inches in width. The color of the lines is not specified so there is flexibility depending on the color of the court itself.

Free Throw Line

For players above the age of 10, the standard free throw lane will be used, which is at a distance of 15 feet. It is also common that another lane will be drawn 2 feet closer to accommodate the physical capabilities of younger players.

Basketball Hoop Height

The basketball hoop will be exactly 10 feet off the ground for all regulated basketball courts. This includes high school courts, NCAA, FIBA, and the NBA.

NBA Basketball Court Dimensions

NBA Basketball Court Dimensions

The standard size of the court for the official National Basketball Association (NBA) is 50 feet wide and 94 feet long. Official courts that host games under International NBA rules will have slightly smaller dimensions.

The half-court line will be 47 feet long and will be right in the center of the court. The free-throw line will be situated 19 feet from the edge of the field and 15 feet from the backboard. The three-point line is 23 feet and 9 inches from the center or 34.75 feet from the center of the basketball hoop.

FIBA Basketball Court Dimensions

The International Basketball Federation also known as FIBA has a standard size for their courts at 49.2 feet in width and 91.9 feet in length for all professional basketball games. As you’d expect, the half-court line will be right in the center, which means 45.95 feet from either side.

At 22.15′ from the center of the basketball hoop, you will find the three-point line. The placement of the free-throw lane is 19 feet from the edge of the field and 15 feet from the backboard.

There are a lot of weird measurements and complicated numbers to keep in mind regarding the size of a FIBA court, but if you were to convert them into meters, things would be a lot easier. This is because, in meters, a FIBA court will have a standard size of 15 meters wide and 28 meters long.

College Basketball Court Dimensions

A basketball court designed for NCAA games won’t be very different from an NBA court, except for the three-point line, which will a little closer. Just like the NBA courts, these will also be 50 feet wide and 94 feet long, with a line for the half-court area of 47 feet in the courtyard’s center.

The free-throw line will also be 15 feet from the backboard front and 19 feet from the edge of the field. The three-point shooting line will be situated at a distance of 22.15′ from the center of the hoop.

As you might have noticed, there is a one and a half feet difference in the distance of the three-point line between these two leagues. This can be quite a challenge, especially for someone that is making a transition from college leagues to professional basketball. Players will have to prepare in advance to get used to the new dimensions and get higher accuracy when starting to play for professional leagues.
