Where to stand in doubles: standard, I and Australian

Pick the formation that deletes their favourite return. Stand where it says.

Key facts

1
The doubles court is 10.97 m wide against 8.23 m for singles, 2.74 m wider, with 1.37 m added by each alley. The length, 23.77 m, doesn't change.
ITF Rules of Tennis
2
The service boxes are identical in singles and doubles. The alleys come into play only after the serve.
ITF Rules of Tennis
3
Only the server and the receiver are constrained in where they stand at the moment of service. Partners may stand anywhere on their side.
4
In the Australian formation both serving partners line up on the same side, which removes the cross-court lane and forces the lower-percentage down-the-line return.

Why it works

The wider doubles court matters after the serve, not during it. The alleys add width on each side, so angles and net coverage decide points rather than long baseline rallies. The serving team's edge is that it chooses its shape first.

In standard formation the server defends the cross-court reply while the partner guards the alley and looks to intercept the middle. Cross-court is the returner's comfortable shot for the same reason as in singles: the court is longer and the net is lower in the middle.

The I-formation puts the net player crouched astride the centre service line, so the returner can't read which side either partner will cover. The move is signalled in advance. The Australian lines both partners up on one side and takes the cross-court away. Use either when the cross-court return is hurting you, or to set up a poach behind a serve to the T.

Drill: The formation rotation

15 min · with a partner

With four players, serve four points in standard, four in I and four in Australian. Keep the same server and agree the signal before each point.
The returner's partner marks where each return went: cross-court, down the line, middle or lob.
The server's partner marks whether both serving partners were in the agreed spot at the returner's contact. Then switch roles.

Questions players ask

What is the Australian formation in tennis?

Both serving partners line up on the same side of the court. It removes the cross-court return and forces the returner down the line, the narrower shot over the higher part of the net.

What is the I-formation in doubles?

The net player crouches astride the centre service line so the returner can't read which side each partner will cover. The move is agreed with a signal before the serve.

When should you switch doubles formations?

When the cross-court return is hurting you, or to set up a poach behind a serve to the T. If a returner keeps hitting clean cross-courts, go Australian first, then try the I if they start finding the line.

Does the doubles alley count on the serve?

No. The service boxes are the same as in singles. The alleys are in play only after the serve.

What this doesn't cover

Rigorous doubles analytics are scarce. Where returns go against each formation comes from coaching consensus, not charted data. There's no sourced figure for how often pros or club players use each formation.

Play the pointHow to communicate with your doubles partnerIn doubles, decide before the ball is hit. The net player sets the play with a hand signal behind the back before each serve. The pair agrees in advance who owns the middle ball, by position and handedness. In the rally you use four words, mine, yours, switch and back, and you call the switch before a lob lands.Play the pointWhen to poach in doubles tennisPoach in doubles when the returner starts their forward swing, not before, or they'll redirect the ball down the alley you just left. You can't wait for contact, because reaction is too slow. Poach more when you're ahead in the game and behind a T serve. Mix in the pinch and the fake so the threat stays real.Play the pointWhere to serve in doubles to set up your partnerIn doubles, serve to set up your partner's volley, not to hit an ace. T and body serves shrink the return angle and feed the poach. Wide opens the court but invites a sharper cross-court reply. Agree the serve target, your partner's move, the expected return and the planned next shot before the toss, as one plan.Play the pointWhen to hit cross-court or down the line in tennisHit cross-court as your default and go down the line only when the court opens: the ball is short, you're inside the baseline and your opponent is wide. Cross-court crosses the net where it's lower, travels into a longer court, and brings the reply back to your side. Down the line reverses all three.
