There are six types of lines on a regulation, indoor volleyball court. As a player or viewer, you may hear the lines be called multiple names:
1. Baselines / End Lines
3. Attack Line / Three-Meter Line
5. Coach Restriction Line
6. Service Line
The baselines or end lines are located on the ends of the court, they mark the end of the backcourt. Depending on who you're talking to, you may hear these lines be called either baselines or end lines. From now on in this tutorial, we'll refer to them as baselines.
These lines can be found on the sides of the court. Behind these lines, you may see coaches, referees, other players, and the media (photographers, film crews).
Together, sidelines and baselines make up the boundary lines of the volleyball court. This is the perimeter of the court that separates in-bounds from out-of-bounds.
The attack line is the line in between the frontcourt and backcourts, dividing each side for front and back row players. This line also marks where players can attack the ball on offense.
This is also called the three-meter line, because it's three meters away from the net, but that can be confusing, so we'll be referring to this as the attack line for the rest of the tutorial.
The centerline is located directly in the middle of the court, right underneath the net and it cuts the court in half.
The coach restriction line marks where the coaches of each volleyball team are allowed to stand. This is the area behind the sidelines.
This is the short line behind the baseline that the server stands behind before each serve. Crossing this line during the serve is a violation. We'll learn more about serving later in this tutorial.
