Wimbledon says it is "confident" more than 25% of fans will be allowed to attend when the tournament returns to the All England Club next month.
Following a number of UK test events with crowds, organisers said they had received "early positive indications" about increasing ticket capacity.
It is hoped all UK limits on social contact will be removed from 21 June.
Wimbledon, which will return on 28 June, can welcome a daily total of 42,000 fans in normal circumstances.
In 2019, when the 13-day tournament was last held, 500,397 spectators attended in total.
The championships were cancelled last year - for the first time since World War Two - because of the coronavirus pandemic.
