The full dimensions of a tennis court, including all the lines and markings, are as follows:
- Baseline: The baseline is the line at the back of the court, parallel to the net. It marks the boundary of the playing area.
- Service Line: The service line is located parallel to the net, halfway between the baseline and the net. It divides the court into two halves and determines the area from which players serve.
- Center Service Line: The center service line is an extension of the service line that runs perpendicular to it, dividing the court into two service boxes.
- Center Mark: The center mark is a small mark located on the center service line, halfway between the baseline and the net. It indicates the center of the court and is used for serving.
- Singles Sideline: The singles sideline is the line that runs perpendicular to the net, marking the side boundaries of the court for singles matches. It is located 27 feet (8.23 meters) from the net.
- Doubles Sideline: The doubles sideline is the line that runs perpendicular to the net, marking the side boundaries of the court for doubles matches. It is located 36 feet (10.97 meters) from the net.
- Service Boxes: The service boxes are the areas between the service line, center service line, and singles sideline. They are used for serving during matches.
- Service T-Line: The service T-line is an extension of the center service line that intersects with the singles sideline and doubles sideline, forming a T-shape. It marks the back boundary of the service boxes.
