Demystifying the Lines: Tennis Court Dimensions and Net Specifications

5th Mar 2025

Tennis, a sport of precision and agility, is played on a court with very specific dimensions. Whether you're a casual player or an aspiring pro, understanding these measurements is crucial. Let's break down the key dimensions of a tennis court and its net.

The Playing Field: Tennis Court Dimensions

A standard tennis court is rectangular and varies slightly depending on whether it's used for singles or doubles play. Here's a breakdown:

  • Overall Court Dimensions:
    • The overall rectangular court, including the out-of-bounds area, is 120 feet (36.57 meters) long and 60 feet (18.29 meters) wide.
  • Playing Area (Doubles):
    • The actual playing area for doubles is 78 feet (23.77 meters) long and 36 feet (10.97 meters) wide.
  • Playing Area (Singles):
    • For singles, the playing area is 78 feet (23.77 meters) long and 27 feet (8.23 meters) wide.
  • Service Lines:
    • The service lines are 21 feet (6.40 meters) from the net.
  • Baseline:
    • The baseline is at each end of the court.
  • Sidelines:
    • The sidelines define the width of the court, and differ depending on if it is a singles or doubles match.
  • Center Mark:
    • A 4-inch (10-centimeter) line marks the center of the baseline.

Net Specifics: Distance and Height

The net is a critical component of the tennis court, and its dimensions are also strictly regulated.

  • Distance Between Net Posts:
    • The distance between the two net posts is 42 feet (12.80 meters). This measurement is taken from the outside edges of the posts. This means that the net extends 3 feet outside of the doubles court sidelines on each side.
  • Net Height:
    • The height of the net at the center is 3 feet (0.914 meters).
    • The height of the net at the posts is 3 feet 6 inches (1.07 meters). This slight difference creates a gentle curve in the net.

Why These Dimensions Matter

These precise measurements are not arbitrary. They're designed to:

  • Ensure fair play: Consistent dimensions across all courts create a level playing field for all players.
  • Maintain the integrity of the game: The specific net height and court dimensions contribute to the unique challenges and strategies of tennis.
  • Allow for accurate line calls: clearly defined lines allow for accurate judgement of if a ball is in or out.

In Conclusion

Understanding the dimensions of a tennis court and its net is essential for anyone who enjoys the sport. Whether you're building a new court, officiating a match, or simply wanting to deepen your knowledge of the game, these measurements provide a solid foundation.
