Clarifying basketball court dimensions I'm checking the standard court dimensions: the width is 4.9 m, and the length from the endline to the free-throw line is 5.8 m. The official free-throw line distance is indeed 5.8 m from the backboard's plane. The FIBA court measures 28 m by 15 m, with a center circle radius of 1.8 m. The three-point line is 6.75 m from the basket center, with a corner distance of 0.9 m. For NCAA/NBA, the free-throw line is 4.572 m from the backboard.Verifying FIBA and NBA distances For FIBA, the free-throw line is 4.6 m from the backboard and 5.8 m from the inner edge of the endline. The basket support distance from the endline is 1.575 m, making the free-throw line distance from the backboard incorrect if I say 4.225 m. Actually, the backboard plane is 1.2 m from the endline, according to FIBA; for the NBA, it's 1.2192 m from the baseline.Confirming court specifications If the distance from the endline to the backboard is 1.2 m, then the free-throw line is indeed 4.6 m from the backboard, making the baseline to free-throw line a total of 5.8 m, which matches up nicely! Now, for some additional dimensions: the basket height is 3.05 m, and the backboard measures 1.8 m by 1.05 m, with the inner rectangle at 0.59 m by 0.45 m. The restricted area semicircle radius is 1.25 m for FIBA and 1.22 m for the NBA, while lines are 5 cm wide. There’s a required minimum clearance of 2 m around the FIBA court, and for surface friction, a coefficient of 0.4–0.6 is recommended. Additionally, standards specify ball rebound of at least 90% compared to concrete.Summarizing material specifications and requirements The slip resistance should have an SRT value between 80-110, and we can simplify the shock absorption to 25-55% for area elastic floors, along with a friction coefficient around 0.4-0.6. For materials: Indoor and outdoor base requirements focus on durability and moisture control, ensuring proper drainage and suitable lighting standards for training and matches.Setting Up Court Specifications For the ancillary court setup, the height of the surrounding fence should be between 3-4 m, with protective barriers in the safety zone behind the baseline. For hoops, there are different types: movable, in-ground, and box-style, using 12 mm tempered glass for backboards with shock-absorbing rims, like the NBA/FIBA breakaway rim. Line colors should be white and 5 cm wide, marking areas like the three-point, free-throw, and restriction zones. Regarding dimensions: FIBA courts are 28x15 m and NBA courts are slightly larger. For 3x3 games, the size is 15x11 m with a 6.75 m arc. It's important to adhere to regulations such as EN 14904 and the appropriate Chinese standards. Budget strategies should consider usage, climate, maintenance, and renovation cycles. When constructing, curing times vary depending on the material. For maintenance, regular cleaning and specific products are crucial, along with seasonal protections and periodic refinishing for wooden floors. Common issues include bubbling, cracking, and noise, but there are solutions for these. Pricing can range widely, so it's best to provide approximate values in RMB while noting regional differences. Overall, I’ll aim for a clear yet concise draft!
