Volleyball court dimensions begin with a rectangle and end with a purchase order. The indoor court is 18 m by 9 m, the beach court 16 m by 8 m, and the paint covers 162 m² indoors against 128 m² on sand. Each figure is correct, and none of them states how much floor a match actually needs.
The difference is the free zone. Add the minimum band and the same court sits inside 360 m²; add the event band and it sits inside 589 m². We work from the rule texts and carry every figure through to the strip layout, because that is where a budget is fixed.
Two Court Sizes, Two Different Games
The FIVB Official Volleyball Rules 2025-2028 set the indoor court at 18 m by 9 m, surrounded by a free zone at least 3 m wide on all sides. The centre line divides it into two halves of 9 m by 9 m.
The same rule book draws the side lines and end lines inside those dimensions, so the 162 m² already contains 5 cm of paint on each edge. A tape run along the outside of the line measures a court nobody plays on.
Beach is a separate product, not a smaller indoor court. The FIVB beach rules measure 16 m by 8 m and state that there is no centre line at all, which changes where a surface seam can fall.
- Indoor, FIVB Rule 1.1: 18 m by 9 m, free zone 3 m minimum, 162 m².
- Beach, FIVB Beach Rule 1.1.1: 16 m by 8 m, free zone 3 m minimum, 128 m², no centre line.
- High school, NFHS Rule 2-1-1: 60 ft by 30 ft measured to the outer edges of the boundary lines, the same court in feet.
The two rectangles differ by 34 m², or 21 percent, before any free zone is counted. That gap is the smallest one in the chain. The two rule sets count the line from opposite faces and still land on the same rectangle, which is why 162 m² holds under both.
Free Zone: Three Legal Answers, Not One
Ask how wide the free zone must be and three governing bodies give three answers. The FIVB minimum is 3 m on all sides. For FIVB, World and Official Competitions the band widens to 5 m from the side lines and 6.5 m from the end lines.
The NFHS court rule asks for at least 6 ft (2 m) of unobstructed space outside the boundary lines and prefers 10 ft. The wording matters: 2 m is legal, and it is not comfortable.
NCAA guidance sets a 2 m minimum and requires 3 m in facilities built after 2016. It prefers 3.05 m outside the side lines and 4.58 m beyond the end lines. Each answer produces a different rectangle, and the arithmetic is plain addition on both axes.
- FIVB minimum: 18 + 3 + 3 = 24 m by 9 + 3 + 3 = 15 m, or 360 m².
- FIVB event: 18 + 2 x 6.5 = 31 m by 9 + 2 x 5 = 19 m, or 589 m².
- NFHS minimum: 18 + 4 = 22 m by 9 + 4 = 13 m, or 286 m².
- NCAA preferred: 27.16 m by 15.10 m, about 410 m².
Subtract the 162 m² court from the 589 m² event floor and 427 m² sits outside the paint. That is the part of volleyball court dimensions most plans leave out. At the minimum, 198 m² of the 360 m² sits outside it. Both numbers are material the client pays for and no line ever encloses.
Between the two indoor bands the floor grows by 229 m², and the court inside it does not change at all.
