When it comes to basketball, the court size plays a crucial role in how the game is played and experienced. Whether you’re a player, coach, or enthusiast looking to create a practice space or simply understand the game better, knowing the dimensions of a half basketball court is essential. This seemingly simple measurement influences everything from shooting drills to game strategy, making it a fundamental piece of basketball knowledge.

A half basketball court is more than just a smaller version of the full court; it serves specific purposes in training, recreational play, and even competitive scenarios. Its size impacts the pace of the game, the types of drills that can be performed, and the overall flow of play. Understanding the dimensions helps in planning layouts for gyms, backyards, or community centers, ensuring the space meets the needs of players and coaches alike.

In the following sections, we will explore what defines the size of a half basketball court, why these measurements matter, and how they compare to full courts. Whether you’re setting up a court for casual play or organizing a professional training session, this knowledge will provide a solid foundation for making informed decisions.

Dimensions and Layout of a Half Basketball Court

A half basketball court is essentially one half of a full basketball court, divided along the midcourt line. The standard dimensions of a full basketball court, as used in professional leagues like the NBA, measure 94 feet in length and 50 feet in width. Consequently, the half court occupies 47 feet in length while maintaining the full width of 50 feet.

The layout of a half court includes several key markings and areas:

  • The three-point line: This arc defines the boundary for three-point shots. In the NBA, the distance from the basket to the three-point line varies from 22 feet in the corners to 23.75 feet elsewhere.
  • The free-throw line: Situated 15 feet from the backboard, this line is where free throws are taken.
  • The paint or key area: This rectangular area under the basket measures 16 feet wide and extends 19 feet from the baseline to the free-throw line.
  • The basket: Positioned 10 feet above the playing surface, centered along the baseline.

Unlike a full court, the half court omits the opposite basket and its corresponding markings. The midcourt line becomes the baseline for the half court setup.

Standard Measurements of a Half Basketball Court

The precise measurements of a half basketball court are crucial for consistent gameplay and training. Below is a table summarizing the key dimensions:

Feature Measurement Unit Notes
Length 47 feet Half of a full 94-foot court
Width 50 feet Same as full court width
Three-point line radius 23.75 (22 in corners) feet NBA standard; varies by location
Free-throw line distance from baseline 15 feet Standard across leagues
Key (paint) width 16 feet Measured from inside edges
Key length (baseline to free-throw line) 19 feet Standard dimension
Basket height 10 feet From playing surface to rim

Variations in Half Court Sizes

While the dimensions above represent the NBA standard, half basketball courts can vary depending on the level of play, location, and specific use cases:

  • High School Courts: Often measure 84 feet in length for full courts, resulting in a half court length of 42 feet. The width is typically the same at 50 feet.
  • FIBA Courts: International basketball courts measure 28 meters by 15 meters (approximately 91.9 by 49.2 feet). Half courts here measure about 45.9 feet in length and 49.2 feet in width.
  • Recreational or Practice Courts: These courts may be smaller to fit available space, sometimes reducing length to between 40 and 45 feet.
  • Portable or Modular Courts: Often designed with flexibility in mind, these can be customized to fit specific spatial constraints while maintaining proportional markings.

Practical Considerations for Half Court Usage

The size of a half basketball court has implications for gameplay, training, and facility design:

  • Training and Skill Development: Half courts provide ample space for shooting drills, one-on-one play, and half-court offensive and defensive strategies without requiring the full court footprint.
  • Space Efficiency: For venues with limited space, half courts allow for multiple games or practices to occur simultaneously.
  • Youth and Amateur Play: Many youth leagues utilize half courts to accommodate smaller players and reduce the physical demands of full-court play.
  • Game Format Adaptations: Half-court games, such as 3-on-3 basketball, rely on these dimensions to ensure fair and standardized play.

Understanding the exact size and layout of a half basketball court is essential for designing appropriate training programs, constructing facilities, and organizing games that adhere to official standards.

Dimensions of a Half Basketball Court

A half basketball court represents one half of a full standard court, typically used for practice, drills, and smaller-sided games. The size of a half court varies depending on the level of play—NBA, NCAA, or high school—and the specific regulations governing the playing area.

Here are the standard dimensions for half basketball courts across different levels:

Level Full Court Dimensions (feet) Half Court Dimensions (feet) Notes
NBA 94 ft (length) × 50 ft (width) 47 ft (length) × 50 ft (width) Half court is exactly half the length of the full court
NCAA 94 ft × 50 ft 47 ft × 50 ft Same dimensions as NBA for half court
High School (NFHS) 84 ft × 50 ft 42 ft × 50 ft Half court is half the length of the full court

The width of the court remains consistent at 50 feet regardless of full or half court play. The length is halved to create the half court. This allows for an official playing area that includes all essential markings such as the three-point line, free-throw line, and restricted area.

Key Markings and Their Placement on a Half Court

A half court must contain the key basketball markings to facilitate official gameplay and practice. These include the three-point arc, free throw lane, and restricted area under the basket.

  • Three-Point Line:
    • NBA: 23.75 ft (22 ft in corners)
    • NCAA: 22.15 ft
    • High School: 19.75 ft
  • Free Throw Line:
    • Located 15 ft from the backboard baseline for all levels
  • Lane (Key) Dimensions:
    • NBA: 16 ft wide
    • NCAA and High School: 12 ft wide
  • Restricted Area Arc:
    • Radius of 4 ft from the center of the basket
    • Prevents defensive players from drawing charges inside this arc

These markings must be accurately measured and painted on the half court to ensure the integrity of the game during practice or half-court matches.

Variations in Half Court Sizes for Recreational and Training Use

While official half courts follow strict dimensional guidelines, many recreational and training courts have variations in size depending on available space and intended use.

  • Smaller Half Courts: Often found in schools or community centers where space is limited, these courts may be shortened further than official half court dimensions, sometimes down to 30-40 feet in length.
  • Adjustable Half Courts: Some training facilities use modular court systems with adjustable boundaries to customize the playing area for specific drills or age groups.
  • Outdoor Courts: Public parks may have half courts with irregular dimensions due to site constraints; however, the width typically remains around 50 feet to accommodate standard backboards and rims.

When constructing or using a half basketball court for non-professional purposes, it is recommended to maintain proportional dimensions to preserve the feel and challenge of the game.
