The 7.32m × 2.44m frame defines the entire geometry a goalkeeper trains around. Coaches use the fixed width to calculate cutting-down-the-angle positioning — how far off the line a keeper should stand for a shot from a given spot — and the fixed height sets the reach a keeper needs to cover the crossbar on long-range efforts. Because the size has never changed while average goalkeeper height has increased significantly since the 19th century, top-level keepers now cover proportionally more of the goal than they did a century ago, which is part of why shot-stopping at distance has become harder for attackers over time.

Net depth, though not strictly regulated by IFAB, matters more than it looks. A shallow net increases the chance of the ball rebounding back into play off the stanchions, creating disputes over whether a goal crossed the line — one reason many professional venues install nets deep enough to fully absorb the ball's momentum well behind the line.

Smaller formats deliberately shrink the goal rather than just the pitch: futsal's 3m × 2m goal is proportionally much smaller relative to its court than an 11-a-side goal is to a full pitch, which is a big part of why futsal produces such high-scoring, technical games — the smaller frame forces more precise finishing rather than simply overpowering the keeper.
