The lines on a tennis court can be quite confusing if it's your first time out but rest assured, each of them serve a purpose.
Each line on a tennis court has its own name and each shot must fall within the respective lines.
Base Line: The back lines which set the court's distance limit.
Singles Lines: The side lines which set the court's width limit when playing singles.
Doubles Line: The side lines which set the court's width limit when playing doubles.
Service Line: The middle lines which divides the serve area into 2 sections.
Center Service Line: The middle lines which set the distance limit for any serve.
Tee: The small center lines which are used as references to help find the base line's center.
Singles Court - 1 VS 1
Points and rallies are played within the base line and the singles lines.
Doubles Court - 2 VS 2
Points and rallies are played within the base line and the doubles lines.
At the start of every point, one of the players must serve into the opposite box from which they are standing, using the Tee as a reference.
