Padel Serve Rules: How to Serve Correctly (and Avoid Common Faults)

The padel serve is unlike anything you have encountered in tennis. There are no thundering overhead smashes, no 200 km/h rockets down the centre line. Instead, the serve in padel is a controlled, underarm action designed to start the point fairly — and once you understand the rules, you will find it one of the easiest parts of the game to get right. That said, there are more ways to fault than most beginners expect, and small technical errors can cost you points before the rally has even begun.

This guide covers everything you need to know: the technique itself, where to stand, what constitutes a fault, when a serve is replayed, and how the service rotation works across a game. If you are brand new to the sport, it is also worth reading our guide to padel for beginners alongside this — the serve makes more sense once you have a feel for the court.

The underarm serve: the basics

Every padel serve follows the same process. You hold the ball in your non-paddle hand, drop it or bounce it on the floor behind the service line, and then strike it underarm as it rises from the bounce. The point of contact must be at or below your waist height — you cannot let the ball rise higher and then swing at it overhead. That is the entirety of the technique in terms of the rules.

In practice, most players develop a gentle topspin or slice action. A flat serve is also perfectly legal. What you cannot do is toss the ball into the air and serve overhead, or strike it before it bounces. The bounce on the floor is compulsory, not optional. Some players new to padel from a tennis background instinctively want to toss and smash — that habit has to go.

There is no requirement to serve with any particular pace. Many experienced players serve with a fair amount of pace and a low bounce to keep the receiver pinned back; others use slice to drag the ball wide. At beginner level, just focus on getting the ball in the right box cleanly and legally. The technique will develop from there.

Where to stand

The service line sits 6.95 metres from the net — roughly in the middle of the court lengthwise. You must stand behind it, not on it. Your position also needs to correspond to the service box you are targeting: if you are serving into the right-hand box on the receiver's side, you stand in the right half of your own end of the court.

Both feet must remain behind the service line for the entire duration of the serve, from the moment you drop the ball right through to the moment you make contact. If either foot touches or crosses the line as you swing, that is a foot fault — and it counts as a fault in exactly the same way as a serve into the net.

The ball travels cross-court diagonally. Serving from the right side of your court, you aim into the left-hand service box on your opponents' side. Serving from the left, you aim into the right-hand box. This mirrors the tennis service direction. If you are unsure which box is which, our guide to how to play padel has a full breakdown of the court layout.

Service faults

A serve is called a fault in any of the following situations:

The ball lands outside the correct service box — either in the wrong box, beyond the back service line, or into the net without crossing over. The ball touches the glass wall on the receiver's side of the court before bouncing on the ground. Even if the ball then somehow drops into the service box, it is still a fault. The wall must not come into play on the serve before the bounce happens. The server steps on or over the service line before striking the ball. The ball is not struck below waist height.

That last point about the glass wall catches people out more than any other. In normal padel rallies, the glass is very much part of the game — players use it constantly. But on the serve, the ball must travel directly through the air from your paddle into the service box. Any wall contact on the way is a fault, no exceptions.

The let

A let is a serve that clips the top of the net and then lands correctly in the right service box. Rather than being called a fault, the serve is simply replayed. You get another attempt with the same fault count — so if it was your first serve and you let, you still have two serves remaining. If it was your second serve and you let, you still have one remaining.

If the ball clips the net and lands outside the service box, or falls back on your own side of the net, it is a fault rather than a let. The key condition is that the ball must clear the net (however narrowly) and land in the correct box. When both of those things happen, you replay.

There is no limit on the number of lets you can serve in a row. In theory you could clip the net five times in succession and replay five times — unusual, but perfectly legal.

Double fault

Two consecutive faults on the same point is a double fault. The receiving pair wins the point outright, with no further play. It does not matter why the two faults occurred — two foot faults, two shots into the net, a fault followed by a wall-touch fault, any combination — two faults means the point is gone.

Because the padel serve is generally forgiving — an underarm action into a reasonably sized box — double faults are more common among beginners than they become with experience. The most frequent cause at club level is not the technique but the nerves: rushing the bounce, swinging before the ball has dropped to waist height, or drifting the foot forward without realising. Slow it down and you will rarely double fault.

Service rotation

Padel uses the same scoring system as tennis, and the service rotation follows a similar logic. The server begins from the right side of the court when the score is 0-0. After the first point is played, regardless of who won it, the server moves to the left side for the next point. The sides alternate throughout the game — right for even-point scores (0, 30, deuce), left for odd-point scores (15, 40, advantage).

One player serves for an entire game. At the end of that game, service passes to the opposing pair, and one of that pair's two players serves the next game. Partners alternate which of them serves each time their pair holds the serve — so if Player A served in game one, Player B serves in game three, and so on.

The receiving side also has a rotation. One player receives on the right and one on the left, and they can choose at the start of the match who takes which side. Receivers keep their sides for the whole set, though they can switch for the next set if they choose.

Common beginner mistakes

Foot faults are probably the single most frequent serving error among new players, and many people commit them without knowing. Watch where your front foot lands after the bounce — if you are stepping forward into the swing, you are likely crossing the line. A simple fix is to practise serving with your feet planted before you drop the ball, rather than using a walking or stepping motion.

Hitting the serve too high is another common issue. Players who come from tennis sometimes let the ball bounce up and swing at shoulder or head height. Keep the contact point at or below the belt — if in doubt, let the ball drop a little lower than feels natural.

Serving into the wrong box happens more than you might expect in the early weeks, particularly when switching between the right and left sides of the court. Before each serve, take a moment to confirm which diagonal you are aiming at. It sounds obvious, but in the middle of a competitive point it is easy to autopilot across.

Finally, some players forget the wall rule and aim for a serve that angles into the side glass on the receiver's side. In a rally that would be a smart play; on a serve it is an automatic fault.

Putting it all together

The padel serve is designed to be accessible, not a weapon. Once you have the underarm technique, the foot position, and the diagonal direction locked in, you will serve cleanly almost every time. Understanding the fault conditions — particularly the wall rule and the foot fault — is what separates players who lose cheap points early in a rally from those who start each point on the front foot.
