What is the maximum depth of a rugby union in-goal area?

The maximum depth of a rugby union in-goal area is 22 metres.

An in-goal area is the space between a goal line and the corresponding dead-ball line. A player scores a try by grounding the ball in the opponents’ in-goal, provided the ball is controlled and the relevant laws are satisfied. World Rugby’s field dimensions allow each in-goal to be no more than 22 metres deep.

The in-goal is not part of the field of play in the narrow dimensional sense, although it is part of the overall playing area. The goalposts stand on the goal line, and the crossbar and uprights form the target for conversions, penalties, and drop goals.

The 22-metre in-goal limit is different from the 22-metre lines marked on the field. Those lines are inside the field of play and are used for restarts and tactical reference; they do not define the try-scoring area.
