Why is football 90 minutes?

Football matches are traditionally 90 minutes long, divided into two 45-minute halves, primarily for historical and practical reasons. The duration was standardized in the late 19th century to create a uniform playing time across matches. This length allows for a balanced game that tests players' endurance and skill while maintaining viewer engagement. Additionally, the time can be adjusted with stoppage time to account for interruptions, ensuring a fair and complete match experience.
