Quartercircle arcs are inscribed with a radius of 14.63 metres (to the closest edge) and a centre 1.83 metres from the middle of each backline, on the inside of the field. The ends of each arc are connected by another straight line that is 3.66 metres long.
At 5.00 metres and 10.00 metres from the middle of each backline and at 5.00 metres and 14.63 metres along each sideline from the backline, a 300mm long line is drawn outside the field of play on each side of both backlines.
A 150mm line is also marked outside the field 1.83 metres from the middle of the backline on each side, and a penalty spot 150mm wide is marked at each end, with its centre 6.40 metres from the middle of the backline.
