The Unique History of Tennis Score Keeping


The game of tennis, with its lush green courts and rhythmic ball strikes, is not just a sport but a legacy passed down through generations. One of the most intriguing aspects of this legacy is its unique score keeping system. Unlike most sports, where points progress sequentially, tennis scoring is an enigmatic mix of numbers and terms that can baffle the uninitiated. This blog post delves into the history of tennis scoring, exploring its origins, evolution, and the reasons behind its distinctive nature.

The Origins

Tennis scoring dates back to the late 15th century in France. The game, originally called “jeu de paume” (game of the palm), involved striking a ball with the hand before evolving to use rackets. The peculiar scoring sequence of 15, 30, and 40 is believed to have medieval roots. There are several theories explaining this:

  1. The Clock Theory: One popular belief is that the scoring was based on the face of a clock. A quarter move of the hand, or 15 minutes, signified the first point. The second point moved it to 30, and the third to 45, which was later shortened to 40 for simplicity.
  2. The Monetary System Theory: Another theory suggests that the scoring was based on the French coin, the denier, with 60 deniers equivalent to a 'jeu' or game. Each point represented a fraction of this total.
  3. The Court Dimensions: Some historians believe the scoring was related to the dimensions of the court, with each point moving the player closer to the net in a series of 15 feet increments.

Regardless of its true origin, this scoring method added a layer of strategy and suspense to the game.

The Evolution

As tennis gained popularity, the scoring system evolved. The introduction of the 'deuce' at 40-40, requiring a player to win two consecutive points to secure the game, was a significant change. This rule was likely introduced to prevent games from dragging on indefinitely and to add more excitement.

The tie-break, introduced in the 1970s, further modernized the scoring system. Before its introduction, sets would continue until a player won two games clear of their opponent, which could lead to excessively long matches. The tie-break system, playing to seven points with a two-point lead, offered a solution to this problem.

The Language of Tennis

Tennis scoring is also unique in its use of specific terminology. Terms like “love” for zero and “deuce” for a 40-40 tie add to the game's charm. The term “love” is believed to come from the French word “l'oeuf,” meaning egg, symbolizing nothing or zero. “Deuce” is thought to derive from the French “à deux le jeu,” meaning “to both is the game,” indicating the tight competition at this point.


The scoring system of tennis is a tapestry woven with historical, cultural, and practical threads. It is a blend of the game's medieval origins, the evolution of its rules, and the distinctive language that surrounds it. This unique scoring not only challenges the players strategically but also adds to the rich, historical tapestry that makes tennis a fascinating sport. As we watch modern champions carving their names in tennis history, it's intriguing to think about how this centuries-old scoring system continues to shape the game's character and competitive spirit.
