Groups will be distanced from others at the event, with bubbles of four being allowed.
The capacity of the venue will be increased as each round takes place - a third of spectators will be allowed to attend the first round with the final taking place at full capacity and with no social distancing.
Fans will be required to wear a face mask at the event and test and trace will be in place.
Tributes will also be paid to the Duke of Edinburgh on Saturday ahead of his funeral at Windsor Castle, with play being stopped for a minutes silence at 3pm.
Kellie Barker has tickets for the event and said that she is excited to back watching live sport, she is going to almost every day of the tournament.
She said: "I feel safe as houses to go really and to have those golden tickets, I do feel very lucky."
She added: "Everybody's lives have been affected in different ways over the past 12 months and snooker means an awful lot to me I go to a number of events every year obviously we haven't been allowed to.
"So this was such lovely news fans could go to Sheffield this time."
Tian Pengfei has been living in Sheffield since the last World Championships 9 months ago, rather than returning to his native China, in order to play at this year's event.
