The lines on a tennis court define the area where the ball is allowed to land during the point. The baseline is the line that represents the furthest back a ball can land; the singles and doubles sidelines mark the outer edge along the side of the court; finally, the service box indicates where a serve has to land.
The singles and doubles sidelines form the side boundaries of the tennis court. In singles games, the sideline lies 13.5 feet away from the center of the court, and extends from baseline to baseline. In a singles game, if a ball lands outside of the singles sideline, it is out-of-bounds. Like the baseline, if a ball lands on the line (but not outside of it), it is still an in-play ball.

The lines on the tennis court indicate boundaries for where the ball can land on a shot and where one can stand when serving.

The Lines of a Tennis Court. Baseline: Doubles 36 feet / Singles 27 feet The baseline runs parallel to the net and defines the farthest boundary, or back of the court, on each side. It’s where you will hit most of your groundstrokes (forehands and backhands) and the approximate location you’ll return serves.
ALLEY – The area between the singles and doubles sideline on each side of the court. (The singles court is made wider for doubles play by the addition of the alley.) APPROACH – The shot hit by a player just before coming to the net. BACKCOURT – The area around the baseline.
A regulation size tennis court is 78 feet long and 36 feet wide. In singles, players can only access the 27 ft. In doubles, players get access to the full 36 feet of court. Before we move towards different court sizes let us understand some of the key tennis court lines and their dimensions: Tennis Court Terminologies
