From the International Rugby Board's website... 1.4 DIMENSIONS FOR GOAL POSTS AND CROSSBAR
(a) The distance between the two goal posts is 5.6 metres.
(b) The crossbar is placed between the two goal posts so that its top edge is 3.0 metres from the ground.
(c) The minimum height of the goal posts is 3.4 metres.
(d) When padding is attached to the goal posts the distance from the goal line to the external edge of the padding must not exceed 300mm.
All rugby posts have a 3m cross bar and the posts are allowed to be as high as possible.
