Check tennis court size and lines.
A tennis court is 23.77 m long, 8.23 m wide for singles and 10.97 m with the doubles alleys. Each service box is 6.4 m deep and 4.115 m wide — half the singles width — which is why service accuracy is measured in a surprisingly small target area. Run-off dominates the site requirement: the recommended 6.4 m behind each baseline nearly doubles the total length needed.
Court and enclosure areas
Court area = 23.77 m x width (8.23 m singles, 10.97 m doubles); service box = 6.4 x 4.115 m; enclosure = (23.77 + 2 x back run-off) x (width + 2 x side run-off)
