The Glastonbury Festival is hoping to expand its capacity by 20,000 for the 2007 festival.
The event is taking a break this year, as it does every five years, but organisers are now trying to work out how to get more punters through the gates.
All 112,500 weekend tickets sold out in less than three hours last year, reflecting the festival's growing popularity. The total capacity is 153,000, including passes for staff, media, artists, locals and guests.
Melvin Benn, who runs the operational side of the festival, told the BBC: "We are going to grow the festival. I'm anticipating growing it by up to 20,000 people next year."
A spokesman for Mendip District Council told the BBC organisers had not informed them of any proposed expansion yet.
The 2007 event is scheduled to take place next June - organiser Michael Eavis has already said he hopes to get Kylie Minogue to play. She was due to headline in 2005, but was then forced to pull out after being diagnosed with breast cancer.
A film of the festival, directed by Julien Temple, is currently being shown at cinemas nationwide.
