Sooner or later you’ll play a pair who seem to be standing in the wrong places, sliding across the court after every serve like they’ve rehearsed it. That’s stacking, and it looks far cleverer than it is. Ten minutes of reading and one patient partner is genuinely all it takes.
What stacking actually is
In standard doubles you start diagonally: server one box, partner in the other. Stacking just means both partners start on the same side, then shift into their preferred halves once the ball is struck. The score and the service rotation still work exactly the same; you’re only rearranging where bodies begin.
Why bother? Because most pairs have a better half each. Maybe your backhand is a rumour and your partner’s is a weapon, so you want your forehand in the middle. Maybe one of you moves better to the left. Maybe (the classic case) one of you is left-handed and you’d both quite like your forehands down the centre, where most balls arrive. Standard positioning forces you to swap halves every time the rotation says so. Stacking lets you keep your favourite halves all game.
Stacking on serve, which is the easy bit
Say you want to end up on the left and your partner on the right, but the rotation has you serving from the right box. Fine: you serve from the right as required, standing close to the centre line, while your partner waits beside you on the outside, near the right sideline. The moment you strike the serve, you slide across to the left half and your partner holds the right. Done. Because the receiving team has to let the serve bounce and return it, you have a comfortable second to sort your feet out.
When you’re serving from the box you already like, nobody moves at all. Half the time stacking means doing precisely nothing, which is the kind of tactic everyone can execute.
Stacking on return, which is not
The returner’s partner normally waits at the kitchen line. In a return stack, the returner’s partner instead stands off the court, beyond the sideline at the net, on the side you both want to vacate. The returner hits the return and sprints to the far half; the partner steps in to the near half. It works, but the returner is doing real running while the ball is live, and a sharp opponent will aim at the space mid-swap. If you’re new to this, stack your serves for a few weeks and leave return stacking until the serving version feels like breathing.
The call system that prevents farce
The whole enterprise collapses if one of you stacks and the other doesn’t, which is why pairs agree calls before the game, not during a rally. Keep it binary: “stack” or “normal” before each serve, said once by the same designated person, usually whoever is fondest of admin. Some pairs signal instead, an open or closed hand behind the back from the net player. Words are easier in a noisy sports hall, and at club level nobody is stealing your signals; they’re busy remembering the score.
When to un-stack
Stacking has a price: transitions. Every slide is a moment when the middle is briefly nobody’s. If you’re losing points during the shuffle, or the wind outdoors is making everything chaotic, or you’re playing with a new partner who nods confidently while understanding nothing, go back to normal positions and win with third shot drops instead. Tactics are meant to serve the pair, not the other way round.
Best place to try it is a quiet club session with a partner you can laugh with, because your first few stacks will deserve it.
