FIFA to Implement New Technology for Offside Detection at 2026 World Cup

The 2026 World Cup will showcase a new generation of refereeing technology, as FIFA announces significant changes to offside detection and VAR systems aimed at faster, more accurate decisions. The most notable innovation is an enhanced semi-automatic offside system designed to alert assistant referees in real-time when a player is clearly offside.

This new system will send an audible signal to the assistant referee if a player is more than 10 centimeters offside, a tighter threshold than the previous 50-centimeter detection limit. While the assistant referee retains the final decision, this technology is expected to reduce instances where offsides are called late or missed, minimizing disruptions and potential injuries from continuing play unnecessarily.

FIFA will also utilize artificial intelligence to create 3D digital models of all 1,248 players participating in the tournament. This scanning process, taking only a second during official team photos, will provide more precise and understandable graphics for offside replays during broadcasts.

Furthermore, FIFA is introducing systems to help VAR more accurately determine if the ball has completely crossed the goal line before a goal is scored. Integrated ball sensors and 3D replays will aid referees in checking ball-out-of-play decisions and corner kicks. New 3D projections will also assist VAR in assessing offside situations where a player's interference with the goalkeeper's line of sight is in question, offering an additional tool for quicker and more reliable judgments. FIFA aims for the 2026 World Cup to be the most technologically advanced in its history.
