Can a Pickleball Go Under the Net? 2026 Rule Explained
No. A return that travels under the net is a fault in pickleball. The legal alternative that often causes confusion is an around-the-post shot: the ball may travel outside the net post and does not have to pass above the net. But going under the net, or through the gap between the net and a post, is different.
The distinction matters most on temporary nets, where a loose bottom edge or visible gap can make an impossible-looking path physically available. The 2026 USA Pickleball rulebook separates these situations within its net-system rules rather than treating every ball that avoids the top tape the same way.
The rule in one table
| Ball path | Ruling | Key distinction |
|---|---|---|
| Over the net and into the opponent’s court | Normal live ball if otherwise legal | Standard return |
| Around the outside of the net post | Can be legal | An ATP does not have to pass above the net |
| Under the net | Fault | Not a legal way to cross to the opponent’s side |
| Between the net and net post | Fault | The post-side gap is not the same as going around the post |
| Into the net and back onto your own side | Fault once the return fails to cross and lands | The ball has not been legally returned |
The useful mental model is simple: over or around can work; under or through the net-post gap cannot.
Why an around-the-post shot is different
An around-the-post shot, usually shortened to ATP, is an explicit exception to the intuition that every return must pass over the net. If a ball pulls you wide enough, you may send your return around the outside of the net post. The ball can even travel below net height.
That last detail is where the confusion starts. “Below net height” does not mean “under the net.” On an ATP, the ball travels outside the post. It is going around the net system, not beneath the mesh.
Picture the net post as the dividing landmark. A low ball that passes outside it may be a legal ATP. A ball that sneaks beneath the bottom of the net is not.
What if there is a gap under a temporary net?
Portable nets do not always sit perfectly flush with the court. The mesh may lift slightly, the center may be tensioned unevenly, or a ball may find a visible opening near the bottom.
That physical opening does not create a legal shot path. If your return passes under the net, the result is a fault even if the ball emerges cleanly on the opponent’s side and would otherwise land in.
This is worth knowing in recreational play because players sometimes reason from the outcome: “It reached the other court, so play it.” The rules care about how the ball crossed, not only where it eventually landed.
Can the ball pass between the net and the post?
No. The narrow opening that can exist between the side of the net and the net post is also not a legal shortcut.
This is different from an ATP by only a small amount of space, but the rules distinction is meaningful:
- Between net and post: fault.
- Around the outside of the post: potentially legal.
On a close play, focus on the ball’s path relative to the post rather than whether the shot looked like an ATP.
Does an ATP have a minimum height?
No. A legal around-the-post return does not need to clear the height of the net. That is one reason sharp crosscourt dinks can create spectacular ATP opportunities: once the ball pulls a player sufficiently wide, the geometry can allow a direct path around the post.
The absence of a minimum ATP height still does not legalize a ball passing underneath the net itself. Height and route are separate questions.
What if the ball hits the net first?
A ball contacting the net is not automatically dead. A normal rally ball can clip the top of the net, cross, and remain in play. Modern serving rules likewise do not use the old recreational “let serve” concept simply because the serve touches the net.
But net contact does not rescue an illegal route. If a return ends up passing under the net rather than legally crossing or going around the post, it is not transformed into a good ball because it touched mesh first.
What if the ball goes into the net and rolls underneath?
This is another temporary-net edge case. Imagine a hard dink or drive hits low on the mesh, drops, then rolls or squeezes underneath to the other side.
Do not judge the shot by its final location. The ball did not make a legal return over or around the net. A ball cannot use the space beneath the net as a route into the opponent’s court.
What about a malformed or malfunctioning net?
A separate issue arises when the net system itself malfunctions during play. The rulebook treats net-system malfunction as a replay situation. That is not the same as voluntarily hitting a ball through an existing opening under a functioning portable net.
For practical play, distinguish these two scenarios:
- The net was already set up with a small bottom gap and your shot goes under it: do not treat the gap as a legal lane.
- The net system actually fails or changes during the rally: the malfunction provisions may apply.
If a portable net is obviously sagging, displaced, or assembled incorrectly before play starts, fix it before the next rally rather than building house rules around the defect.
Five quick examples
1. Low drive squeezes beneath the mesh
Your drive hits near the bottom of a portable net and emerges on the other side through the space underneath. Fault.
2. Crosscourt dink creates an ATP
Your opponent pulls you wide, and you hit outside the post at ankle height into the court. Potentially legal. An ATP can travel below net height.
3. Ball passes through the side gap
The ball travels between the edge of the net and its post. Fault. It needed to travel around the outside of the post for the ATP route.
4. Ball clips the top tape and lands in
Your rally ball touches the top of the net, crosses normally and lands inbounds. Keep playing. Ordinary ball/net contact is a different rule.
5. Net collapses during the rally
The portable net system physically malfunctions while the ball is live. Apply the net-system malfunction/replay rule rather than pretending the altered net is a normal playing condition.
Why this distinction matters in real games
Most players will rarely see a ball travel cleanly under a regulation net, but portable nets make the edge case realistic. Knowing the rule also prevents a more common misconception: that ATPs are legal because “the ball can go anywhere as long as it reaches the other side.”
That is too broad. ATPs are legal because the rules specifically allow the ball to be returned around the net post, without a height restriction. They do not erase the rules for balls traveling under the net or between the net and post.
The simplest way to remember it
When a strange low return happens, identify the route before arguing about the height:
- Did it cross over the net? Normal return rules apply.
- Did it go outside and around the post? It may be a legal ATP.
- Did it pass under the net? Fault.
- Did it pass through the gap between net and post? Fault.
- Did the net system itself malfunction? Check the replay rule.
That route-first test resolves almost every version of the question without relying on how spectacular—or accidental—the shot looked.
