The overlap rule in volleyball

The rule

FIVB rule 7.4 (2025–2028) says that at the moment the server hits the ball, each team must be within its own court (except the server). The players of the receiving team must be in rotation order. The players of the serving team are free to occupy any position.

For the receiving team, the order means two things:

1. Front to back (7.4.2.1): each back-row player must be further from the centre line than the front-row player directly in front of them. The pairs are 4 and 5 (left), 3 and 6 (middle), 2 and 1 (right).
2. Side to side (7.4.2.2): within each row the left-to-right order must be kept: 4, 3, 2 in the front row and 5, 6, 1 in the back row.

Breaking either is a positional fault (rule 7.5): the team loses the rally, and the players are put back in the right places.

How it is judged: feet

Rule 7.4.3 says the positions are judged by the players’ feet touching the floor:

• Front to back: the back-row player must have at least part of one foot further from the centre line than the front foot of the corresponding front-row player.
• Side to side: a right-side player must have at least part of one foot closer to the right sideline than the foot further from that sideline of the other players in the same row. The same works on the left. For the middle player, that simply means being between the two.

In practice that means a back-row player can stand almost touching the heels of the player in front, and two neighbours in a row can stand nearly side by side. Hands, arms and leaning do not count: only feet on the floor.

Neighbours only

You are only compared with the players next to you in your column and in your row. There are no diagonal checks.

So zone 5 and zone 3 are never compared, nor are 4 and 6 or 2 and 6. Zone 4 and zone 2 are only linked through zone 3. A back-row player can legally stand in front of a front-row player who is not in their own column. That is the key to every serve-receive formation.

The 2025 change, and leagues that differ

Older FIVB rules applied rotation order to both teams at the serve. Since 2025, FIVB only checks the receiving team, and the serving team can line up however it likes, as long as everyone except the server is on the court.

Many competitions have not followed, or follow a different rulebook: for example, US high school and college volleyball and plenty of local and school leagues. Some national federations adopt FIVB changes a season or more later. Check which rule your league uses. The overlap trainer has a switch for the older rule where the serving team is checked too.

Stacking and hiding players

Teams use the neighbours-only rule to put players close to where they want to be after the serve. This is called stacking or hiding.

Example: Rotation 5 in a 5-1 (setter in zone 3, middle blocker in zone 2, opposite in zone 6). The setter wants to be at the target on the right. The setter only has to stay left of the zone 2 player and in front of the zone 6 player. So the middle blocker stands right up against the right sideline at the net, the setter stands just to their left, also at the net, and the opposite stays back. When the serve is hit, the setter takes one step to the target and the middle runs in to attack.

Example: Rotation 1 (setter in zone 1). The setter must be behind the zone 2 player and right of the zone 6 player. The setter usually stands deep on the right, behind the zone 2 player, and runs forward to the target as the ball is served. Nobody needs the setter to pass, so the other receivers cover the court in front.

Example: hiding a front-row player. A middle blocker in zone 3 who should not pass can stand right at the net. The zone 6 player then only has to be slightly deeper than that, so the back-row passers can spread across the court.

To see every rotation laid out, use the position explorer.

Common mistakes

• The setter leaves too early. In Rotation 1 the setter steps forward before the serve and ends up level with or in front of the zone 2 player. Wait for the contact.
• Swapping sides in the front row. In a rotation where the outside hitter is in zone 2 and the opposite in zone 4, they may not cross before the serve. Stand next to each other, then switch.
• Forgetting the libero. The libero takes the exact place in the order of the player they replaced. If they replaced the zone 5 player, they must be behind zone 4 and left of zone 6.
• Checking the wrong players. Players often worry about diagonal neighbours, which do not count, and forget the player directly in front.
• Judging by the body. Leaning past a teammate is fine; only the feet count.

Positional versus rotational fault

A positional fault is standing in the wrong place at the serve. A rotational fault is serving out of order (rule 7.7). Both cost the rally, but a rotational fault can also wipe out points scored while the order was wrong. See substitutions and rules.

Practise it

Drag players around the overlap trainer and it tells you, live, whether the line-up is legal and which pair is overlapping.
