- "Sidelines: Sidelines define the lengthwise boundaries of the field. When the ball crosses over a sideline, it is out of bounds. The sidelines are also called touchlines.
- Goal lines: Goal lines mark the widthwise boundaries of the field. When the ball crosses over a goal line, it is out of bounds.
- Center line: The center line divides the field in half across the width of the field.
- Center circle: The center circle is a circle 20 yards in diameter around the midpoint of the center line.
- Penalty area: Also referred to as the 18-yard box or just the box, the penalty area is a rectangle 44 yards wide and 18 yards long, and is centered at each end of the field. A penalty arc intersects the top of the box. The arc is a semicircle with a 10-yard radius, and its center is the penalty mark.
- Goal area: A smaller rectangle within the penalty area, the goal area is 20 yards wide and 6 yards long, and is centered at each end of the field. The edge of the box that’s parallel to the goal line is often referred to as the six-yard line.
- Goal: The goal is a net set over a rectangular frame, made up of two vertical goalposts and a horizontal crossbar. The goal is 24 feet wide and 8 feet tall, and is centered along the goal line.
- Penalty mark: A small mark that sits 12 yards away from the goal line, the penalty mark is centered directly in front of the goal.
- Corner arcs: The corner arcs are four quarter circles drawn at a 1-yard radius from each corner of the field.
- Flags: Small flags on bendable poles located at each corner of the field help officials tell when a ball crosses over a sideline or a goal line or when it goes out of bounds in the corner area"
