Kickball Field Lines

Get ready to learn about the lines you see on a kickball field. We'll explain all the lines you need to know to play the game and understand as a fan.


To understand kickball, we must first learn about the playing surface or the kickball field. There are three (3) types of lines you should know:

The Foul Lines

The foul lines, often colored white or yellow, partially outline the field of play. They extend from the kicking box to the foul poles located deep into left field and right field. We'll learn more about the kicking box and foul poles later in this chapter.

The Baselines

The baselines are the straight lines in between each of the bases. The baselines between 1st base and 2nd base, and 2nd base and 3rd base are invisible and not marked on a kickball field. However, the baselines between home plate and 1st base, and 3rd base and home plate coincide with the foul line.

IMPORTANT: The baselines are important for baserunning, which we'll learn more about in future chapters.

The Sidelines

The sidelines are lines that extend from each cone in the kicking box to the end of the field usually to a fence or other perimeter. They form the sideline areas and team sidelines, two (2) components on a kickball field which we'll learn about next.

The 1st To 3rd Diagonal

The 1st to 3rd diagonal is an important line to know when playing kickball. It is an imaginary line that connects a point on 1st base to a point on 3rd base. It is used to align fielders before every pitch. All fielders must be on or behind this line and in fair territory prior to the pitch thrown by the pitcher. The pitcher and catcher are the only fielders that do not have to be behind this line. If a fielder is not behind the 1st to 3rd diagonal, a position warning may be called by the referee depending on league rules.
