A Half Court in tennis represents one side of the regulation tennis court, with distinct measurements for singles and doubles play.

The full tennis court measures 78 feet in length by 36 feet in width for doubles matches, and 78 feet by 27 feet for singles matches. Understanding half court dimensions proves crucial for players maintaining proper court positioning and avoiding penalties during match play.

Court Dimensions and Layout

The half court contains several essential boundary markers and lines that define legal play areas.

The baseline runs parallel to the net, marking the court’s rear boundary at either 36 feet wide for doubles or 27 feet for singles play. Any ball landing beyond this line results in an out call.

A center mark, measuring approximately 4 inches in length, divides the baseline and runs perpendicular to the net. This marking helps players maintain proper serving position, as they must not cross this mark when delivering serves.

The service line spans 27 feet in width, running parallel to the net midway between the net and baseline. This line creates the service boxes and defines the legal landing area for serves.

The center service line extends 42 feet, dividing the service area into equal boxes on either side of the half court.

Boundary Lines

Singles sidelines extend 39 feet perpendicular to the net, establishing lateral boundaries for singles matches.

Doubles sidelines, positioned several feet outside the singles lines, also measure 39 feet and define the wider court dimensions used in doubles play.

Practical Applications

Half court configurations serve multiple purposes in tennis. Beyond traditional match play, these dimensions accommodate various training exercises and alternative sports.

Tennis players frequently employ half court drills during practice sessions and warm-ups to improve shot efficiency and court positioning.
