Volleyball Rules, Positions & Court Dimensions – Complete Guide
Explore indoor volleyball rules, player positions, scoring, rotations and court dimensions in one practical guide. Whether you are learning the sport, helping a school team or checking a court measurement, this page explains the essentials of six-player indoor volleyball.
A standard indoor volleyball court is 18 metres long and 9 metres wide, with a net dividing it into two equal halves. Each team has six players on court. Teams usually have up to three contacts to return the ball, excluding a block contact. Most sets are played to 25 points, with a two-point winning margin.

Volleyball Court Diagram
This original, simplified diagram shows a standard indoor court, its centre line, attack lines and the six numbered rotational positions on one side. It is illustrative rather than a construction drawing.
How to read it: Positions 2, 3 and 4 are front-row positions; 1, 6 and 5 are back-row positions. The diagram shows Team B facing the net at the top of its half. The serve is normally taken by the player in position 1, from the service zone behind the end line.

Volleyball Positions and Player Roles
There are six players per team on court, but a team's tactical roles are different from its numbered rotational positions. Players rotate through the six court positions, while teams use formations and substitutions to place specialists where they are most effective.
Six Rotational Positions
Position 1: right back (the serving position). Position 2: right front. Position 3: middle front. Position 4: left front. Position 5: left back. Position 6: middle back.
Common Specialist Roles
- Setter: organises attacks by delivering accurate sets to hitters.
- Outside hitter: attacks from the left side and often helps receive serves.
- Opposite hitter: commonly attacks from the right side and supports blocking.
- Middle blocker: specialises in quick attacks and blocking near the centre of the net.
- Libero: a specialist back-row defender who wears a contrasting jersey and is subject to special replacement and playing restrictions.
- Defensive specialist: a back-row-focused player used by some teams, without the libero's special status.
Volleyball Rules Explained
1. Starting a rally and serving
A rally starts with a serve from behind the end line. The server sends the ball over the net into the opposing court. Under standard rules, the server has eight seconds after the referee's whistle to serve. The ball may touch the net and still be legal if it crosses correctly.
2. Three team contacts
A team normally has up to three contacts to return the ball. A block contact does not count towards these three in indoor volleyball. A common sequence is pass (dig), set and spike. Some consecutive contacts by the same player are permitted in specific situations, such as after a block; ordinary double contacts and catches remain regulated.
3. Rally-point scoring
Every rally produces a point for one team. A team scores when the ball lands in the opponent's court, the opponent commits a fault, or the opponent receives a penalty. A ball touching a boundary line is in.
4. Sets and winning a match
Standard indoor matches are best of five sets. Sets one to four are played to 25 points, and a deciding fifth set is played to 15 points. Every set must be won by at least two points. A team wins the match by winning three sets. Recreational competitions may use shorter formats.
5. Rotations
When the receiving team wins a rally, it earns the serve and its players rotate clockwise one position. Players must respect their rotational order at the relevant moment of service. Once the serve has been hit, they can move into tactical playing positions, subject to front-row and back-row restrictions.
6. Front-row and back-row restrictions
Front-row players can attack and block at the net. Back-row players may attack a ball entirely above net height only if they take off from behind the attack line; they cannot complete a block. The libero has additional restrictions, including on blocking and attacking a ball entirely above net height.
7. Touching the net and crossing the centre line
Not every contact with the net or movement under it is automatically a fault. The rules distinguish illegal net contact during playing action and interference with an opponent from permitted movements. Crossing beneath the net is regulated for safety and interference.
8. Ball-handling faults
Common faults include catching or throwing the ball instead of rebounding it, certain illegal successive contacts, and making four team contacts before returning the ball. Referees judge the action according to the official rules, not simply whether it looks unusual.
9. Substitutions and libero replacements
Ordinary substitutions follow the competition's substitution limits and procedures. Libero replacements are handled separately under special rules. The libero generally plays in back-row positions and wears a contrasting uniform.
Volleyball Scoring Example
If the score is 24–24, a team must reach a two-point lead, such as 26–24 or 28–26, to win the set. In a deciding fifth set, 14–14 similarly continues until one team leads by two points.
Indoor Volleyball vs Beach Volleyball
Indoor volleyball normally uses six players per team on an 18 m × 9 m court. Standard beach volleyball uses two players per team on a smaller 16 m × 8 m court. Scoring, block contacts, substitutions and other rules also differ. This guide focuses on indoor volleyball.
Volleyball Equipment and Beginner Tips
Basic equipment includes a suitable volleyball, regulation net and marked court. Appropriate non-marking indoor shoes and comfortable sports clothing help players move safely. Beginners should practise controlled forearm passing, setting, serving, court communication and safe movement near the net.
