The dimensions of the touch field shape every decision a team makes. Knowing the numbers — and what they mean — is the difference between a player who reacts to space and a player who reads it.
The field is 70 meters long between the two try lines and 50 meters wide. Each end has a try zone 7 meters deep, where attacking players ground the ball to score. The total length from in-goal to in-goal is 84 meters.
The 7-meter retreat after every touch is the single most important spatial constant in touch. Defenders are pulled back 7 meters every time a touch is made — nearly a tenth of the field re-opened to the attack on every play. The attacking team is built around exploiting this space. The defending team is built around closing it quickly.
A penalty resets defenders 10 meters back. This is a much bigger reset and it changes the geometry of the play that follows. Knowing when the next play starts from a 7-meter advantage versus a 10-meter advantage shapes whether the attack goes quick or sets up.
Inside 7 meters of the try line the rules change slightly. Defenders retreat to the try line, not 7 meters back. Space is maximized, the attacking team has the structural advantage, and red-zone plays become highly effective.
