NBA vs. FIBA Court Geometry & 3-Point Arc Differences
- 3-Point Arc Geometries: The NBA 3-point line is set at 23 ft 9 in (7.24 m) at the apex, tapering to 22 ft (6.71 m) at the baseline corners (3 ft from sidelines). FIBA uses a 6.75 m (22 ft 1.7 in) arc tapering to 6.60 m (21 ft 7.8 in) in the corners.
- Hardwood Flooring: Professional courts utilize tongue-and-groove North American hard rock maple (Acer saccharum) laid over subfloor rubber cushioning pads to absorb knee impact and ensure consistent 93%+ ball rebound.
