Understanding the Duration: How Long is a Soccer Game in the World Cup?

A match in the FIFA World Cup doesn't simply comprise ninety minutes of playtime. There are many elements to consider when understanding a soccer game's true length. Understanding these factors equips fans, players, and coaches in much wealthier ways and enhances the viewing experience. So let's explore these elements in detail.

To start with, a typical soccer match comprises two halves of 45 minutes each, which sums up to 90 minutes. But that's only part of the picture. Playing time is frequently interrupted for various reasons, such as injuries, goal celebration, tactical instructions, and substitutions. As a result, additional time, commonly known as "stoppage time" or "injury time", is added at the end of each half.

According to FIFA's Laws of the Game, stoppage time is determined by the referee at their discretion and is mainly added for substitutions, assessment of injury to players, removal of injured players from the field of play for treatment, wasting time, and any other cause. This often adds an extra 3-6 minutes to the game, although this varies depending on the match's flow.

Furthermore, World Cup knockout stage matches can extend considerably. If a knockout game ends in a draw after 90 minutes, two additional 15-minute periods of extra time will ensue, potentially lengthening the match to 120 minutes – not even including possible stoppage time at the end of those extra periods.

Should the teams still remain level after extra time, the often frenetic 'penalty shootout' comes into play. Each team takes turns to try and score from the penalty spot with five attempts each—the team with the highest number of successful penalties wins. The duration of a penalty shootout varies, but it can often add at least 20 minutes to the game's total length, including preparation time for the shootout and celebrations or commiserations afterward.

Furthermore, the halftime break should not be neglected in the overall game duration. It typically lasts 15 minutes and is a critical period for teams to regroup, strategize and recover.

Also, brief interruptions occur due to Video Assistant Referee (VAR) reviews. The VAR system was introduced in the 2018 World Cup to help referees make decisions regarding goals, penalties, straight red cards, and mistaken identity incidents. It contributes minor but significant additional time to the matches duration.

All these factors combined can turn a 90-minute game into a two-hour (or longer) commitment.

The duration of a soccer game in the World Cup is traditionally 90 minutes, broken down into two 45-minute halves with a 15-minute halftime break. However, various factors such as extended time, injuries, and the referee's discretion, among others, could impact the overall length of these matches.

Extended time, or additional time, also known as stoppage time, is the extra minutes added at the end of each half to compensate for time spent on instances such as injuries, substitutions, and delays due to the disciplinary actions. The amount of added time is determined by the fourth official, who refers to the notes kept by a match referee regarding these incidents. In most matches, it ranges from 1 to 6 minutes but could be more in some cases.

Injuries during the game can cause substantial disruptions, leading to games being much longer. Serious injuries which require immediate medical attention and removal of the player from the field may result in several minutes of stoppage time at the discretion of the referee. Football's governing bodies are increasingly focusing on player safety, leading to games being paused for longer periods to enable appropriate medical assessment and treatment.

As for the referee’s discretion, the Laws of the Game allow the referee to add extra time for various reasons depending on the circumstances. These could include unnecessary time-wasting, prolonged disruptions like goal celebrations, or any other activities that could cause an unnecessary delay in the restart of the game. It's worth noting that the referee has complete discretion over the amount of added time.

The use of Video Assistant Referee (VAR) technology has also introduced another element potentially extending the duration of the matches. This technology allows a team of video referees to review decisions made by the head referee with regard to goals, penalties, red cards, and mistaken identity incidents. The implementation of VAR in the 2018 World Cup led to several instances of extended time due to video reviewing.

On the other hand, Extra Time, which should not be mistaken for extended time, is another factor affecting the duration of matches, particularly in the knockout stages of the World Cup. If a game is tied at the end of regular 90 minutes, it proceeds to extra time, which consists of two 15-minute halves. This is followed by a penalty shootout if the score remains level even after extra time.

Lastly, weather conditions can also affect match duration.
