In tennis, “Ad” is short for “Advantage.”
It refers to the point scored after deuce (40–40) that gives one player or team the temporary lead. If the player with the advantage wins the next point, they win the game. If they lose it, the score returns to deuce.
If you’ve ever watched a tennis match and heard the umpire call out “Ad in!” or “Ad out!” and thought, Wait… what just happened? you’re not alone. Tennis scoring is famously quirky, and the term “Ad” is one of the biggest sources of confusion for beginners.
Yet once you understand it, “Ad” becomes one of the most exciting moments in tennis. It signals pressure, momentum swings, and game-defining points. Whether you’re a casual viewer, a new player, or someone brushing up on tennis terms, this guide will walk you through exactly what “Ad” means in tennis, where it comes from, how it’s used in real matches, and how it compares to modern scoring formats.
By the end, you’ll hear “Ad” and instantly know who’s ahead, why it matters, and what could happen next.
What Does “Ad” Mean in Tennis Scoring?
In simple terms:
- Ad = Advantage
- It happens only after deuce (40–40)
- It gives one player a one-point lead
- The game is won if the advantaged player wins the next point
Basic Flow of Tennis Scoring
- 0 = Love
- 1 point = 15
- 2 points = 30
- 3 points = 40
- Tie at 40–40 = Deuce
- Next point = Ad
How “Ad” Works Step by Step
Here’s how a typical game reaches and uses “Ad”:
- Player A: 40
- Player B: 40
- Score becomes Deuce
- Player A wins the next point → Ad In (if serving) or Ad Player A
- Player A wins the following point → Game won
- If Player A loses that point → back to Deuce
This back-and-forth can repeat multiple times before the game is decided.
Ad In vs Ad Out: What’s the Difference?
You’ll often hear two specific calls during matches:
Ad In
- Advantage to the server
- Called when the server wins the point after deuce
Ad Out
- Advantage to the receiver
- Called when the receiver wins the point after deuce
These terms help players and spectators quickly identify who has the edge.

The word “Advantage” comes from French tennis traditions, where early forms of the game used phrases like avantage to indicate a lead.
Over time:
- “Advantage” was shortened to “Ad”

- Umpires adopted the shorter call for speed and clarity
Despite modern innovations, “Ad” remains a core part of traditional tennis scoring.

An “Ad” point is often called a pressure point, because:
