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.
The All England Club is continuing to leave some decisions on this year’s event – including ticketing and prize money – until as late as possible because of the ongoing uncertainty about the easing of restrictions.
Online ticket sales are not expected to begin before the middle of June.
“We are confident we will be able to increase our ticketing capacities for the championships this year beyond the minimum 25% position we set out last month,” said organisers.
