List of gridiron football rules
"Yard lines" cross the field every , and are numbered every 10 yards from each goal line to the 50-yard line, or midfield (similar to a typical rugby league field). Two rows of short lines, known as inbounds lines or "hash marks", run at 1-yard (91.4 cm) intervals perpendicular to the sidelines near the middle of the field.
