In a singles match, players must serve from between the singles lines.
Doubles Lines (Tram Lines)
The Double lines or Tram lines divide the doubles playing area. In a doubles match the full borders of the court are used including the outer sideline. The doubles playing area is 2,74 meters (9 feet) wider.
In a doubles match players can serve between the center line and the outer sideline.
Service Boxes
The Service Boxes mark the area where the ball must land on the serve.
