Wimbledon plans to abandon its traditional rest day on the middle Sunday of the tournament from 2022.
The Grand Slam will instead be played over 14 consecutive days, with All England Lawn Tennis Club chairman Ian Hewitt saying this was possible because of better grass-court maintenance.
Organisers also revealed they are hoping to have fans at a minimum of 25% capacity this year.
Ticket prices will stay at 2020 levels, with prize money yet to be decided.
"Over time Wimbledon has continuously evolved to meet changing demands and behaviours of our fans - always changing, always staying the same is something we talk about often," AELTC chief executive Sally Bolton said.
