FAQ
Which 3-point line is further — NBA or FIBA?
At the corners, the NBA line (6.70m) is essentially the same as FIBA (6.75m). At the top of the arc, the NBA extends to 7.24m — significantly further than FIBA's uniform 6.75m.
What is the 3-point line distance in NBA vs FIBA?
The NBA 3-point line ranges from 6.71m (22 feet) at the corners to 7.24m (23 feet 9 inches) at the top of the arc. FIBA's 3-point line is 6.75m (22 feet 1.75 inches) throughout (no corner difference). The NBA line is slightly longer, particularly at the top of the arc, which is why players who transition from international basketball often shoot a higher percentage initially.
What are the main rule differences between NBA and FIBA?
Key differences: game length (NBA: four 12-minute quarters; FIBA: four 10-minute quarters); shot clock after offensive rebound (NBA: 14 seconds; FIBA: 14 seconds, same); defensive 3-second rule (NBA only); 3-point line distance (NBA slightly longer); challenge system (NBA has coaches challenges; FIBA uses video review differently). Zone defence rules also vary slightly. The games are recognisably similar but these differences affect pace and strategy.
