Wimbledon has shifted from human line judges to electronic line-calling, marking teh first time in its 148‑year history that on-court line calls will be made by machines rather than observers. The change comes as players, umpires, and fans acclimate to a system already in use at other major tournaments.
Historically, the best line officials earned modest daily wages, with some early rewards such as free meals or tournament tickets. In today’s landscape,top officials can reach around £200 per day plus expenses.Yet money was never the sole driver for those who spent long hours crouched over chalk lines,determining where a ball landed in a split second.
For many longtime officials, the experience went beyond pay. Close proximity to star players during iconic moments and the personal rituals surrounding Wimbledon offered intangible moments that were hard to quantify. The atmosphere-the chalk-white uniforms, the ceremonial habits, and the unique feel of Centre Court-was part of the game’s character.
One former line judge recalled the thrill of being on the grass during a major final and the camaraderie of the officials as among the sport’s strongest memories. Another veteran highlighted the distinctive uniforms as part of why Wimbledon stood out from other tournaments.
Officials’ leader Malgorzata Grzyb, head of the association of British Tennis Officials, emphasized that the official attire had become a symbol of the sport’s identity. She noted that such personality was a big part of Wimbledon’s appeal, even as new technology takes centre stage.
With the shift to electronic line calling, Wimbledon joins a growing trend where technology handles precise line decisions. Players and umpires are already accustomed to the system at many other events, and the green grass courts-with their muted advertising and all-white attire-will now host a noticeably quieter game of calls.
Yet not everyone sees the change as a simple upgrade.Critics argue that removing line judges erodes some of Wimbledon’s cherished tradition, while supporters contend that the move enhances consistency and fairness through machine accuracy. The debate mirrors broader questions about how much tradition should yield to technology in sport.
BBC Sport has reached out to players, umpires, and officials to gauge reactions and gather perspectives on the shift.
| Aspect | Before | Now |
|---|---|---|
| Line calls | Made by human officials on court | Made by electronic line-calling systems |
| Tradition | Central to Wimbledon’s identity (uniforms,rituals) | Tech-forward approach; reduced on-court drama from line calls |
| Perceived value by officials | Monetary incentives varied; the experience was highly valued | Experience continues to be valued,but calls are automated |
| Public atmosphere | Engaged by visual cues of officials in white | Quieter on-court calls; atmosphere shifts with technology |
Evergreen insights

Electronic line-calling promises greater consistency, faster adjudication, and the potential for elite matches to hinge on uniform standards. As leagues embrace automation,the conversation around tradition versus progress remains central,inviting fans to weigh nostalgia against the benefits of precision and transparency in sport.
Beyond tennis, the decision underscores how major events balance heritage with innovation. Expect ongoing dialog about training, system reliability, and how to preserve the human element in officiating through education and oversight, even as machines assume more responsibilities on the field of play.
