Estimate the material tonnage needed to build a basketball court based on official dimensions and custom pavement specifications.
For a standard NBA full court (94' x 50') with a 5' run-off, the total paved area is (94 + 10) × (50 + 10) = 104' × 60' = 6,240 sq ft. For a 4-inch aggregate base (145 pcf), the volume is 6,240 ft² × (4/12) ft = 2,080 ft³. The tonnage is (2,080 × 145) / 2000 ≈ 150.8 tons. A 5% waste factor results in a final order of ~158.3 tons.
The Basketball Court Calculator is a comprehensive planning tool engineered for contractors, project managers, and homeowners aiming to build a high-quality outdoor basketball court. This calculator simplifies the critical task of estimating the necessary quantities of construction materials, specifically aggregate and asphalt. By providing presets based on official court dimensions from governing bodies like the NBA, FIBA, and NCAA, it ensures that your project starts with a foundation of accuracy. Whether you're building a regulation court for competitive play or a custom backyard court, this tool provides the flexibility to tailor every detail to your specific needs.
A primary advantage of the Basketball Court Calculator is its ability to accurately convert project dimensions into the material quantities you actually need to order. Materials like stone and asphalt are ordered by weight (tons), but are planned by volume (covering a specific area to a certain depth). Our calculator performs this essential conversion using industry-standard material densities, eliminating guesswork and preventing common costly errors. This ensures you can confidently request quotes from suppliers without the risk of over-ordering and wasting money, or under-ordering and causing construction delays and potential pavement defects.
The Basketball Court Calculator is also designed with real-world construction practices in mind. It allows you to select between two common pavement structures: a traditional "Asphalt over Aggregate Base" design or a "Full-Depth Asphalt" design, automatically adjusting the required layers and providing sensible thickness defaults for each. Furthermore, it incorporates a waste factor, a crucial element for any construction budget, to account for material lost during transport and application. For those interested in the official regulations, the NBA's official court dimension rules provide a detailed reference. For more technical information about asphalt itself, Wikipedia's entry on Asphalt Concrete offers valuable insights.
Ultimately, the Basketball Court Calculator serves as an indispensable tool in the initial planning phase of any basketball court construction project. It empowers you to budget effectively, compare costs between different pavement designs, and communicate clear material requirements to suppliers. By taking the complexity out of the calculation, the Basketball Court Calculator helps ensure your project begins on a solid, well-planned foundation, setting the stage for a durable, professional-quality court that will last for years to come.

While 3 feet is often considered the absolute minimum for safety, a 5 to 10-foot run-off is highly recommended. It provides players with enough space to slow down without crashing into fences or landscaping, significantly reducing the risk of injury during aggressive play.
The asphalt base course provides the primary structural strength of the pavement using larger aggregates. The surface (or wearing) course uses smaller aggregates to create a smoother, denser, and more uniform playing surface, which is ideal for consistent ball bounce and player footing.
No. A stable foundation is essential. The native soil (subgrade) must be properly graded and compacted. Then, a layer of compacted aggregate base should be installed. Paving directly on unprepared soil will lead to rapid cracking, sinking, and failure of the court.
Dense-graded asphalt is a standard, relatively impermeable mix that relies on a surface slope to shed water. Open-graded (porous) asphalt is designed with voids that allow water to drain through it, helping the court dry faster after rain. Porous asphalt often requires a special stone reservoir base layer beneath it.
