One of the most common beginner questions in pickleball is simple: when is the ball in, and when is it out? Knowing the answer helps you make better calls, avoid unnecessary arguments, and play with more confidence.
The basic rule
A ball is in if it touches any part of the line. A ball is out only if it lands completely outside the line.
That means even a very small touch on the line counts as in.
How lines work in pickleball
In pickleball, the lines are part of the court area they define. That is why a ball that clips the sideline or baseline is still good.
- Baseline: If the ball touches the baseline, it is in.
- Sideline: If the ball touches the sideline, it is in.
- Centerline on the serve: The serve must land in the correct service box. If it touches the centerline and goes into the correct box, it is out because it touched the wrong boundary for that box.
- Kitchen line: On a serve, if the ball touches the non-volley zone line, it is out, because that line is part of the kitchen.
Special serving rule to remember
The most important exception for beginners is the serve. A legal serve must land beyond the kitchen. If the served ball touches the non-volley zone line, the serve is out.
What about close calls?
If you are making your own line calls, only call the ball out when you clearly see space between the ball and the line. If you are unsure, the fair call is to play it as in.
Simple way to remember it
If the ball touches the line, it is in - except when a serve touches the kitchen line, which makes the serve out.
Final tip
Good line calls are part of good sportsmanship. Stay calm, make clear calls, and give the benefit of the doubt when you are not certain.
