In short
The answer first
Width stretches a defence across the pitch; depth stretches it towards its own goal and back towards midfield. Used together, they create passing lanes and force defenders to choose between protecting central space, following a runner or stepping towards the ball. The aim is not to occupy every blade of grass, but to make the defending team guard more space than it can control comfortably.
Key takeaways
Width can come from a winger, full-back or any player holding an outside position.
Depth includes runs behind the defence and support behind the ball.
Good spacing gives the ball carrier options at different distances and angles.
Players may rotate, but the team still needs someone to preserve each useful space.
An attack can have plenty of possession and still be too narrow or too flat.
Make the defence choose
A winger on the touchline asks the full-back to move away from the centre. A striker threatening the space behind asks the centre-back to turn towards goal. A midfielder offering underneath asks another defender to step forward. These movements create value before any of those players receive the ball.
If everyone moves towards possession, the defence can shrink the playing area. If the attack preserves width and depth, one defender's decision usually opens a different route.
Depth works in both directions
Depth is often described as a run behind, but the player behind the ball matters too. That supporting option lets an attack recycle possession, switch sides or escape pressure without forcing a low-percentage pass.
The best structures therefore contain a threat beyond the line and a safe connection behind the action. One stretches the defence; the other keeps the attack alive.
A viewing check
When an attack stalls, look at the distances between its front five players. Are two occupying the same lane? Is anyone threatening behind? Is the far-side winger still wide, or has the pitch become crowded around the ball?
The next successful pass is often created by a player who never touches the ball. Their position forces the defender to hesitate, and that hesitation gives somebody else time.
