Guides · Doubles strategy
Quick answer: stacking means lining up so that, once the serve and return are made, each partner ends up on the side they prefer, usually so both forehands are in the middle or a left-hander and a right-hander each cover their forehand side. It is legal as long as the correct player serves from the correct side and the correct player receives. The trick is in where the non-serving or non-receiving partner stands, and how they switch after the first shot.
In normal doubles, partners switch sides every time their team wins a point on serve, so half the time a player is stuck on their weaker side. Stacking fixes that. It looks confusing from the outside because players start in odd places and run across the court after the first shot, but it follows a few simple patterns. The diagrams below show your team in yellow at the bottom and the opponents in blue; dashed arrows show where players move.
The rules do not care where you are after the ball is served and returned. They only fix who serves, from which side, and who receives. That is covered in the doubles rules.
The server must serve from the correct side for the score. In this example the server (S) belongs on the right but wants to play the left. The partner (P) stands off to the side of the server, near the right sideline or just outside the court, instead of on the left. After the serve, the server moves left and the partner stays right.
Because the serving team stays back for the third shot anyway (the two-bounce rule), there is plenty of time for this switch. The partner just has to stay out of the server’s way and avoid standing in front of the serve.
This is the harder one. The receiver (R) must return from the correct side. The partner (P) stands at the kitchen line on the same side as the receiver, out of the way near the centre or the sideline. After the return, the receiver runs forward and across to their preferred side while the partner slides over.
The return must be deep and high enough to give the receiver time to cross. A short, fast return makes the switch a race you will lose. If the return is weak, abandon the switch and stay where you are.
A half stack is a lighter version used by many rec teams. Instead of standing off court, the non-receiving partner stands at the kitchen line near the centre line, slightly to the receiving side. If the switch is on, they slide; if not, they are already in a normal position. It is less disruptive and easier to abandon mid-point.
You can practise the doubles patterns that make stacking worthwhile, getting to the line and owning the middle, in the free online pickleball game here, which has a doubles mode with an AI partner.

After a side out, or when the score makes your preferred server the second server, you may have to start a point in a normal formation and then switch. Good stacking teams always know two things before every point: who is serving or receiving, and whether they will switch after the first shot. If you are not sure, do not switch; an unforced position error is worse than a backhand in the middle.
