Pickleball Rules Explained: Serve, Faults, and Line Calls

The official rules of pickleball are published by USA Pickleball (usapickleball.org) and are updated periodically. The core rules cover how to serve legally, what constitutes a fault, how lines are called, and who scores. This guide covers the rules that matter most in recreational and competitive league play.

Serve Rules

Every serve must satisfy three conditions at the moment of contact: (1) the arm must be moving in an upward arc (underhand swing), (2) the paddle head must be below the wrist, and (3) contact must be made below the server's waist (navel height). These three conditions together define a legal volley serve.

1. 1Stand behind the baseline. Both feet must be behind the line before serving.
2. 2Swing upward (underhand arc). The paddle head stays below the wrist at contact.
3. 3Contact the ball below your waist.
4. 4Aim diagonally to the opposite service box. The ball must clear the NVZ and its lines.
5. 5Only one serve attempt is allowed per turn. A let (net cord into the correct box) is replayed under older rules, but since the 2021 update, a let serve is live.

The Two-Bounce Rule

After the serve, the ball must bounce once on each side before either team may volley. The receiving team lets the serve bounce; the serving team then lets the return bounce. Only after these two bounces can players volley freely. Violating the two-bounce rule is a fault.

The Non-Volley Zone (Kitchen) Rules

No player may volley (hit the ball in the air before it bounces) while standing inside the NVZ or touching the NVZ line. This applies to both feet and any body part. A player may step into the kitchen to play a ball that has already bounced there, but must return to outside the NVZ before volleying again. The momentum rule extends this: if a player's momentum from a volley carries them into the NVZ, it is a fault even if the ball has already been struck.

Common Faults

Line Calls

A ball that lands on any line (except the NVZ line on a serve) is in. The NVZ line is in for all regular play but counts as a fault if the serve lands on it. In recreational play, the player on the side where the ball lands makes the call. The convention is: if you are not sure, the ball is in. Calling a ball out requires certainty that the ball was outside the line.

Let Serves

Under the 2021 USA Pickleball rule change, a let serve (a serve that clips the net and lands in the correct service box) is no longer replayed. It is a live ball. This rule change brought pickleball in line with tennis. Check your local league rules, as some recreational leagues still replay let serves by custom.

Doubles-Specific Rules: Server Rotation

In doubles, each team gets two serves per turn (one for each partner), with one exception: at the very start of the game, the first serving team has only one serve. When the serving side loses a rally, the serve passes to the partner. When the second partner also loses a rally (or the team faults), the serve passes to the opposing team. Players announce the score as three numbers: server score, receiver score, server number (1 or 2).
