A head string in pool, also known as the head line, is a key marking on a billiard table used during specific parts of the game.
Defining the Head String
Based on standard terminology in billiards:
The head string is a line connecting the second diamonds of the side rails at the head end of a billiard table that marks a limit on or within which the cue ball is placed in lagging for the break or beginning the game.
This line is essentially an imaginary (or sometimes physically marked) line that stretches across the width of the table.
Key Characteristics of the Head String
Here are the fundamental aspects of the head string:
- Location: It is located at the "head end" of the table, which is the end where the balls are racked for a new game.
- Reference Points: It connects the second diamonds located on the two side rails of the table. Diamonds are the inlay markers along the rails used for aiming and measurement.
- Purpose: Its primary function is to define an area or limit for placing the cue ball, specifically:
- During the "lag" (the process players use to determine who breaks first).
- When starting a new game (placing the cue ball for the opening break shot).
How it's Used
The head string creates the area known as the "kitchen" or "behind the head string." In many games, the cue ball must be placed behind this line (closer to the head rail) when starting the game or after certain fouls. During the lag, players shoot the cue ball from behind the head string towards the foot cushion.

| Location | Head end of the billiard table |
| Connection | Second diamonds of the side rails |
| Function | Marks a limit for cue ball placement |
