Answer: High School Basketball Court Dimensions

A high school basketball court measures 84 feet long by 50 feet wide. The free-throw line is 15 feet from the backboard, and the three-point line is set at 19 feet 9 inches from the basket. The key (painted lane) is 12 feet wide.

Full Breakdown of High School Basketball Court Dimensions

Court Size Overview

• Length: 84 feet

• Width: 50 feet

• Total Playing Area: 4,200 square feet

This size is smaller than an NBA or college court, which measures 94 x 50 feet. The reduced length slightly changes the pace of the game, often favoring quicker ball movement and faster transitions.

The Key (Painted Lane or Free-Throw Lane)

• Width: 12 feet

• Length (from baseline to free-throw line): 19 feet

• Free-Throw Line Distance: 15 feet from the backboard

The key is where post play, rebounding, and free throws happen. Its narrower width compared to the NBA’s 16-foot lane emphasizes fundamentals over sheer physical dominance.

The Three-Point Line

• High School Distance: 19 feet 9 inches from the center of the basket

• College Distance: 22 feet 1¾ inches

• NBA Distance: 23 feet 9 inches

This shorter arc rewards developing shooters and encourages more perimeter play at the high school level.

The Hoop and Backboard

• Rim Height: 10 feet from the playing surface

• Backboard Dimensions: 6 feet wide by 3.5 feet tall

• Inner Rectangle (Shooter’s Square): 24 inches wide by 18 inches tall

These are standardized across all levels of organized basketball, ensuring that shooting fundamentals transfer seamlessly as players advance.

Sidelines, Baselines, and Center Circle

• Sidelines (court length): 84 feet

• Baselines (court width): 50 feet

• Center Circle Radius: 6 feet

• Free-Throw Circle Radius: 6 feet

These markings help regulate jump balls, inbounds plays, and spacing during set offenses.

Comparison: High School vs. College vs. NBA Courts

Key Takeaway: High school courts are slightly smaller, creating faster games with less spacing. Players transitioning to college must adjust to a longer floor and deeper three-point line.

Why the Dimensions Are Important

For Players

• Shooting adjustments: Three-point shots are closer, encouraging confidence.

• Conditioning: Slightly smaller court means faster tempo, but less overall running than college/NBA.

• Skill development: Tighter spaces emphasize passing, dribbling, and teamwork.

For Coaches

• Strategy: Plays must be designed with reduced spacing in mind.

• Defense: Press defenses are more effective in smaller courts.

• Training: Helps prepare athletes for the physical leap to bigger courts later.

For Fans & Parents

• Appreciation: Knowing dimensions helps you understand why certain plays work.

• Player development: Encourages supporting athletes as they adapt to new levels.
