Hyde Park in London can hold up to 65,000 people for large-scale outdoor concerts and events. This capacity is regarded as the official maximum for concerts such as the BST Hyde Park festival and other major gatherings in the park.
Historically, some concerts have drawn audiences exceeding this number, such as the Rolling Stones in 1969 with an estimated 250,000 attendees, but for regular event planning, the official capacity is 65,000.
Thus, the standard capacity for Hyde Park events is 65,000 people.
