A professional NBA court is 94’ x 50’ | 28.65 x 15.24 m. Courts are comprised of several foundational components: the baskets, the three-point arcs, free-throw (foul) lines, and the half court line. Indoor courts are usually made with polished wood (often maple), while outdoor courts are typically made from paving, concrete, or asphalt.
