Understanding official volleyball court dimensions matters whether you’re building a court, coaching, or just want to understand the game better. Here’s an accurate breakdown based on official FIVB (Fédération Internationale de Volleyball) rules, along with the court layout, positions, and key terms every player should know.
Volleyball Court Dimensions
Court Size
A standard indoor volleyball court measures 18 meters long by 9 meters wide (about 59 ft by 29.5 ft). The court is divided by a center line into two equal halves, each measuring 9m by 9m (29.5 ft by 29.5 ft) — this applies at every level of play, from high school through the Olympics.
Free Zone
Surrounding the court is the free zone, an obstruction-free area players can move into during play. The general minimum is 3m (about 9.84 ft) on all sides. For FIVB World and official competitions, this extends to a minimum of 5m from the sidelines and 6–6.5m from the end lines, giving top-level players more room to play balls near the boundary.
Ceiling Height
Vertical clearance matters too, though it’s easy to overlook. The minimum ceiling height above the court is 7m (about 23 ft) for standard sanctioned play. For FIVB World Championships and other top-tier international events, the requirement rises to 12.5m (about 41 ft) — high enough to accommodate the full trajectory of powerful serves and spikes. Many gyms and recreational facilities don’t meet this higher standard, which is one reason top-level matches are held in specific arenas.
Playing Surface
The court surface must be flat, level, and free of any obstruction that could interfere with play. Indoor courts are typically wood or a synthetic sports surface. Outdoor (non-beach) courts require a slight slope — commonly cited as about 5mm per meter — to allow rainwater to drain off properly.
Court Markings
All court lines must be white and a uniform 5cm (about 2 inches) wide.
- Boundary Lines: The sidelines and end lines mark the outer edges of the playing court. These lines are considered part of the court itself — a ball landing on the line is ruled in play, not out.
- Center Line: Runs directly beneath the net, dividing the court into two equal 9m x 9m halves.
- Attack Line: Positioned 3m (about 9.84 ft) from the center line on each side, this line marks the boundary between the front zone and back zone, and determines where back-row players are allowed to attack from. In elite competition, the attack line is extended beyond the sidelines with a series of short broken marker lines to help officials judge close calls.
Volleyball Net
The net is 1m (about 3.28 ft) wide (top to bottom) and typically 9.5–10m long, positioned at the center of the court over the center line.
- Men’s competition: Net height is 2.43m (about 7.97 ft), measured at the center of the court.
- Women’s competition: Net height is 2.24m (about 7.35 ft).
Flexible antennas — thin fiberglass rods about 1.8m (5.91 ft) long and 10mm in diameter — are attached to the net near each sideline, extending about 80cm above the net’s top edge. Any ball crossing the net must pass between the antennas to be considered in play; the ball is out if it crosses outside either antenna, even if it lands within the court boundaries.
Volleyball Court Layout and Positions
A volleyball team has 6 players on the court at once — 3 in the front row and 3 in the back row — and the court is divided into 6 numbered zones to track player positions and rotations:
- Back row: Zone 1 (right back), Zone 6 (center back), Zone 5 (left back)
- Front row: Zone 2 (right front), Zone 3 (center front), Zone 4 (left front)
The attack line separates the front zone from the back zone. Back-row players may attack the ball from behind this line but generally aren’t allowed to attack from in front of it, which is part of why understanding this line’s placement matters for both players and officials.
Rotation in Volleyball
Each time a team wins the serve, players rotate one position clockwise around the court, with the player entering the right-back position (Zone 1) becoming the new server. This rotation system ensures every player cycles through both front-row and back-row positions over the course of a game.
A quick note on scoring near the net: if the ball touches the net, cables, poles, or the referee’s stand during play, this doesn’t automatically end the rally the way some players assume — specific rules govern exactly what counts as a fault, and these can vary slightly by rule set (FIVB vs. NCAA vs. NFHS), so it’s worth checking your specific competition’s rulebook for exact scoring situations.
Understanding official volleyball court dimensions — from the 18m x 9m playing surface to net height, free zone, and ceiling clearance — helps you appreciate why the game is played the way it is, and matters directly if you’re building or certifying a court for real competition.

Frequently Asked Questions
What is the official size of a volleyball court?
A regulation indoor volleyball court measures 18m by 9m (about 59 ft by 29.5 ft), divided into two equal 9m x 9m halves by the center line.
How high is a volleyball net?
The net is set at 2.43m (about 7.97 ft) for men's competition and 2.24m (about 7.35 ft) for women's competition, measured at the center of the court.
How far is the attack line from the net?
The attack line is positioned 3m (about 9.84 ft) from the center line on each side of the court, marking the boundary between the front and back zones.
What is the minimum ceiling height for a volleyball court?
The general minimum is 7m (about 23 ft). For FIVB World Championships and other top-tier international events, the requirement increases to 12.5m (about 41 ft) to accommodate high serves and spikes.
How wide are the lines on a volleyball court?
All court lines are 5cm (about 2 inches) wide and must be white. The boundary lines are considered part of the court, so a ball landing on the line is ruled in play.
