The 30-second version
- A ball touching any part of a boundary line is “in” — with one exception.
- The exception: a serve that lands on the kitchen line is a fault (short serve).
- You call the lines on your own side of the net; any genuine doubt goes in favor of your opponent.
- Make calls promptly and out loud — if you don’t call it out quickly, the ball is in.
Part of our complete guide to pickleball rules.
Line calls are where pickleball’s honor system lives. In rec and most tournament play there’s no referee on your lines, so knowing the rules — and the etiquette — keeps games fair and friendly. Here’s how it works.
What counts as “in” vs. “out”?
The rule is simple: if any part of the ball touches any part of the line, it’s in. The lines are part of the court. A ball only counts as “out” when it lands completely outside the boundary with no contact on the line.
The one big exception: the kitchen line on a serve
There’s a single important exception. A serve that lands on the kitchen (non-volley-zone) line is a fault — a short serve. The serve must clear the kitchen and its line entirely to be good. Every other line on the court counts as “in” when touched, including the baseline and sidelines on a serve.
Who calls the lines?
You are responsible for calling the lines on your own side of the net — the balls landing near you. You don’t call balls on your opponent’s side; they call those. This works because you have the best view of the balls closest to you.
Benefit of the doubt goes to your opponent
This is the heart of pickleball sportsmanship: if you’re not sure whether a ball was in or out, it’s in. You can only call a ball “out” if you clearly saw space between the ball and the line. Any genuine doubt is resolved in your opponent’s favor. When in doubt, play it.
Make the call promptly
Out calls must be made quickly and audibly — call “out” the instant you see it, before you or your partner hits the ball. If you play the ball and then try to call it out, it’s too late: the ball is in. A late call is not a valid call.
Line-calling etiquette
- Be honest. The system only works on integrity — call them as you truly see them, even against yourself.
- Partners can help. In doubles, either partner can make the call; if partners disagree, the ball is in.
- Ask if unsure. You can ask your opponents for their view, but the call is ultimately yours on your side.
- No re-dos except a genuine “let” — like a stray ball rolling onto your court from elsewhere, which stops the point.
Line calls are part of the complete rules of pickleball — worth reading alongside faults and the kitchen rules.
Frequently asked questions
Is a ball on the line in or out in pickleball?
In. If any part of the ball touches any part of the line, the ball is in — the lines are part of the court. The only exception is a serve landing on the kitchen line, which is a fault (short serve).
Who calls the lines in pickleball?
Each side calls the lines on its own half of the court — you call the balls that land near you, and your opponents call theirs. You have the clearest view of the balls closest to you.
What if you’re not sure if a ball was in or out?
The ball is in. You can only call a ball “out” if you clearly saw a gap between the ball and the line. Any genuine doubt is resolved in your opponent’s favor — when in doubt, play it.
Can you call a ball out after you hit it?
No. Out calls must be made promptly and audibly, before you play the ball. If you hit the ball and then try to call it out, the call is too late and the ball counts as in.
Is a serve on the kitchen line good in pickleball?
No. A serve that lands on the kitchen (non-volley-zone) line is a fault. The serve must clear the kitchen and its line completely, unlike the baseline and sidelines, where a ball touching the line is in.
