This article delivers a clear and practical comparison of court sizes and key markings at every competition level: NBA, FIBA (international), NCAA (college), and high school. Whether you need to meet international standards, national regulations, or local school requirements, this overview outlines the critical differences and similarities that affect planning, installation, and compliance. Use this guide to ensure your next basketball facility is built to the precise specifications demanded by each governing body.

Why Basketball Court Size Matters for Sports Flooring Projects

When specifying sports flooring for basketball, understanding the exact size of the basketball court is crucial. For architects, specifiers, installers, and facility owners, the court’s dimensions directly influence the project’s scope, compliance requirements, and the choice of flooring system. The correct basketball court dimensions ensure that every element—from line marking to subfloor structure—meets the performance and safety standards demanded by governing bodies. This is especially important when aiming for FIBA certification or meeting EN 14904 standards, where precision directly impacts playability and long-term durability.

How the Size of Basketball Court Affects Flooring System Selection

Selecting the right sports flooring system depends on the size of the basketball court and its intended use. For example:

  • Full-size NBA or NCAA courts require sports floors that can accommodate larger spans and higher usage demands.
  • FIBA and high school courts, with their unique dimensions, benefit from flooring systems that are adaptable and certified for the specific requirements of each level.

Junckers offers a comprehensive range of solid hardwood sports floors designed for varying court sizes:

  • Fixed sports floors (DuoBat 120+, UnoBat 78+, UnoBat 62+, UnoBat 53/68/80, UnoBat 45/50, Clip System)
    • Suitable for permanent installations in arenas, multi-purpose halls, and sports centers.
    • Available in different construction heights for both new builds and refurbishments.
    • For more information on a high-performance system for larger courts, see the DuoBat 120+ product page.
  • Portable sports floors (Pro Complete 44, Arena Master)

The choice of system impacts installation time, durability, and long-term maintenance requirements, making it essential to match your flooring solution to the size and function of the basketball court.

While both Olympic (FIBA-standard) and NBA basketball courts are designed for elite play, they differ in several important ways:

Court Size: NBA courts measure 94 × 50 ft (28.65 × 15.24 m), while Olympic courts are slightly smaller at 91 ft 10 in × 49 ft 3 in (28 × 15 m).

Three-Point Line: The NBA arc is deeper—23.75 ft at the top, 22 ft in the corners—compared to FIBA’s 22.15 ft at the top, 21.65 ft in the corners.

Center Circle: NBA courts use a 12 ft diameter, versus 11 ft 10 in in Olympic courts.

Free Throw Line & Key: Both formats keep the rim at 10 ft and the free throw line 15 ft from the backboard, but the NBA and FIBA keys are both around 16 ft wide, compared with narrower 12 ft keys at NCAA and high school levels.

Safety Zones: NBA arenas often mandate larger buffer zones around the court, while FIBA requirements are flexible depending on venue configuration.

Materials: Both competitions require solid hardwood courts—typically maple—to ensure consistency in ball response, durability, and safety.
