Out of Bounds. Boundary Lines, Borders.
There are a number of lines on a soccer field. None of them are called boundary lines. The touch lines run up and down the length. They form the sides. The goal lines are across the ends of the field. The touch lines and goal lines define the field's perimeter or its boundary. And a ball that is in play must wholely cross one of these lines (either on the ground or in the air) to be considered out of play.
Surveyors (sometimes called Engineering Surveyors) lay out boundary lines between parcels of land, and draw maps.
They are called touch lines. They are longer than the goal lines, which have goals on them.

The boundary lines at the ends of the field are "goal lines" or "end lines". The long boundary lines at the sides of the field are "touch lines" or "side lines". In FIFA Laws of the Game, Law 1 describes the field of play in more detail.
The black lines mean it is a state boundary.
