How Did Tennis Scoring Start? Why Do We Say Love, 15, 30, 40?
Tennis is a sport filled with tradition, precision, and—let’s be honest—a few quirks. One of the biggest head-scratchers for new fans is the scoring system. Why do we count in increments of 15? Why is zero called “love”? And why doesn’t the score go from 30 to 45 like it logically should?
In this article, we’ll explore the history and logic (or lack thereof!) behind tennis scoring. Let’s dive into how this unusual system started and why it stuck.
A Brief History of Tennis: Where It All Began
Before we get into the numbers, it helps to understand where tennis came from.
Tennis originated in France in the 12th century, evolving from a handball-like game played by monks called jeu de paume (game of the palm). Instead of rackets, they used their hands to hit the ball. Over time, rackets were introduced and the game became more formalized.
By the 16th century, tennis had developed into a popular pastime among European royalty, especially in France and England. The version we play today—lawn tennis—emerged in the late 1800s in England.
But the quirky scoring system predates lawn tennis and likely comes from those earlier French versions.
Why 15, 30, and 40? Theories Behind the Numbers
At first glance, the tennis score progression—0, 15, 30, 40—seems odd. Why not just go 1, 2, 3?
There are a few popular theories:
The Clock Face Theory
One of the most widely accepted explanations is the clock face theory:
- In early French tennis, players used a clock to keep score.
- The hand would move to 15, then 30, then 45, and finally 60 (which represented game point).
- Over time, 45 was shortened to 40—possibly to make the game flow faster or simply due to speech simplification.
This theory gives us the now-familiar sequence: 0, 15, 30, 40.
The Money Betting Theory
Another theory suggests the numbers come from money betting increments used in medieval France:
- Players would bet in units of 15 deniers (a type of currency).
- So 15, 30, and 45 deniers might represent a rising stake.
- Again, 45 possibly became 40 due to simplification.
While this theory is less supported historically, it’s an interesting perspective on how economics might have influenced sports.
Why Is Zero Called “Love”?
The term “love” for zero is just as baffling for beginners. Here’s how that likely came to be.
The French Word “L’oeuf”
Most historians agree “love” comes from the French word “l’oeuf”, meaning “egg”. An egg’s shape resembles a zero, so players started using it as slang.
When English speakers adopted tennis, “l’oeuf” may have sounded like “love”—and the term stuck.
It’s similar to how “duck” means zero in cricket, also because of the egg-like shape.
What About Deuce and Advantage?
Tennis doesn’t just stop at quirky point counts—it adds layers like “deuce” and “advantage” to determine the winner of a game.
What Is Deuce?
- When both players have 40 points (i.e., 40–40), the score is called “deuce.”
- It comes from the French word “à deux,” meaning “at two,” indicating both players need two consecutive points to win.
What Is Advantage?
- After deuce, if a player wins the next point, they gain the “advantage.”
- If they win the following point, they win the game.
- If they lose it, the score returns to deuce.
This system adds suspense and competitiveness to each game, especially during tight matches.
A Simple Breakdown of Tennis Scoring
Let’s simplify tennis scoring for those still scratching their heads:
- Points: 0 (love), 15, 30, 40, then game
- Deuce: When both players reach 40
- Advantage: A player must win two points in a row after deuce to win the game
- Games & Sets:
- A player must win 6 games to win a set (with at least a 2-game lead)
- Matches are typically best of 3 or 5 sets
Why Didn’t Tennis Just Modernize Its Scoring?
In a world of data, tech, and clarity, you’d think tennis would update its scoring system. So why hasn’t it?
Tradition Matters
Tennis is a sport deeply rooted in tradition and elegance. The unusual scoring is part of its identity. Changing it would be like changing chess piece names—it just wouldn’t feel right.
Viewer Engagement
Oddly enough, the scoring system builds suspense. A 40–40 deuce battle can be more thrilling than a simple point count. It keeps both viewers and players on edge.
Global Familiarity
Despite being unusual, the current system is now globally recognized. Updating it would create confusion across generations of fans and players.
Fun Facts About Tennis Scoring
Here are a few trivia nuggets for tennis fans:
- The fastest recorded tennis serve was over 160 mph—good luck keeping track of points at that speed!
- In early Wimbledon tournaments, there were no tie-breaks—some matches went on for hours.
- The longest match ever, between Isner and Mahut in 2010, lasted over 11 hours with a final score of 70–68 in the fifth set.
Conclusion: Strange, But Iconic
Tennis scoring may seem confusing at first, but it’s a fascinating part of the sport’s rich history. Whether it’s love, 15, or a dramatic deuce, each term carries centuries of tradition that make tennis more than just a game—it’s a legacy.
Now that you understand why tennis uses terms like “love,” “15,” and “40,” you can watch matches with a whole new level of appreciation.
