How Long is a Basketball Court? A Complete Guide to Dimensions

Whether you are building a backyard hoop, coaching a youth team, or just curious while watching an intense game, you might wonder about the exact length of a basketball court.

The short answer is that the length depends entirely on the level of play. A professional court is much larger than the one you will find at a local middle school.

This guide will break down everything you need to know about basketball court lengths, widths, and key boundary lines across all major leagues.

Standard Basketball Court Length by League

Basketball governing bodies establish unique regulations to match the physical capabilities of their players.

Professional athletes require more running space compared to young children who are just learning the fundamentals.

NBA and WNBA Court Dimensions

For both the National Basketball Association (NBA) and the Women's National Basketball Association (WNBA), court sizes are identical.

This 94-foot length provides the ultimate stage for fast breaks and high-flying athletic plays.

NCAA College Basketball Court Dimensions

College basketball follows the exact same footprint as the professional ranks to prepare athletes for the next level.

Both Men's and Women's NCAA games share these exact proportions.

FIBA International Court Dimensions

International competitions, including the Olympic Games and the FIBA World Cup, utilize metric system blueprints.

As you can see, a FIBA court is roughly two feet shorter than an NBA court, which slightly alters game spacing.

High School Basketball Court Dimensions

High school gyms across North America scale things down just a bit to accommodate teenage endurance levels.

While the width remains standard, losing 10 feet of length changes how teams transition from defense to offense.

Junior High and Middle School Court Dimensions

Middle school courts are designed for younger players who do not have the lung capacity of older teenagers.

These compact dimensions ensure that games remain fast-paced and fun rather than exhausting for the kids.

Essential Markings on a Basketball Court

The overall length of the hardwood is only one part of the story. The interior lines dictate the rules of the game.

The Half-Court Line

The mid-court line divides the playing surface into two equal halves.

Once an offensive team advances the ball past this line, they cannot pass it back across without forcing a turnover.

The Three-Point Arc

The distance to the three-point line varies significantly across different levels of basketball.

The Free Throw Lane and Key

Often called "the paint," this restricted area sits directly beneath the basket.

Backyard and Half-Court Dimensions

If you want to build a basketball court at home, you do not need a full-sized arena.

Most residential properties utilize a half-court setup. A standard backyard half-court usually measures 30 feet long by 50 feet wide.

This layout gives you plenty of space to shoot three-pointers and practice free throws without taking over your entire yard.
