59' x 29'6" (18x9m)
This rectangle is surrounded by a "free zone" area which should be 9'10" wide on all sides. This is not always the case when you attend small tournaments. All qualifers and national events should meet the free zone requirements.
The height that is free from obstructions should be a minimum of 23' (7m)
USAV allows the free zone to be 6'6 3/4"
FIVB requires a free zone area of 5m on the side lines and 8m on the endlines,
with 12.5m in height from the playing surface.
Playing Surface:
Flat, horizonal and uniformed
Lines are 2" wide, light color that is different from the floor andother lines marked on the floor.
Center line:
is the 2" line that divides the playing court into two equal courts measuring 29' 6" (9x9m). The line extends beneath the net from sideline to sideline.
Boundary lines:
are the two end lines and side lines that mark the playing court. They are drawn inside the dementions of the playing court.
Attack line:
Also known as the 10’ line. This is a line 9'10" (3m) from the net that separates the back row players from the front row.
Attack line Extentions:
There are 5, 6" short lines 2" wide that extend from the sidelines, for a total length of 70". These extended lines are usually only seen in nationally sanctioned competitions.
