The standard dimensions of a rugby field are described below. A rugby field is wider then an American football field and the goalposts are placed at the goal line (try line) not the back of the end zone. However, it should be noted that rugby field size indicate measurements that the field cannot exceed. And just as in other sports, youth games are often played on smaller fields.
Rugby Field Dimensions:
The length of a rugby field are not to be greater than 100 meters long, not including the dead ball area. The width should not be greater than 70 meters
The halfway line marks the field in half regardless of the size of the field.
10 Meter Line
The 10 meter line is marked 10 meters from the halfway line on either side. The 10 meter line marks the distance that a kickoff must travel.
22 Meter Line
The 22 meter line is measured from the goal line (or try line).
The “in goal” is the equivalent of the end zone in football. It is marked by the “Try” (goal) Line and the Dead Ball Line at the back of the zone. The size of the In Goal area is not less than 10 meters where practicable and not greater than 22 meters.
The Goal Posts
The goal posts in Rugby shares the same dimensions as NFL Football. In meters the goal is 5.6 meters wide and 3 meters high at the crossbar.
