Liverpool are to increase their rail seat capacity at Anfield to over 10,000, when the Premier League season resumes on 26 December.
The additional 2,500 rail seats will be added to the existing 7,800 between the Kop and Anfield Road stands.
The initiative is part of a club trial after concerns over "persistent standing" of fans were raised in 2021.
"The health and safety of supporters when attending matches is paramount," said managing director Andy Hughes.
"Following a review of the initial rail seating trial last season, we will now expand the trial and introduce rail seating in additional areas of the Kop to further address crowd safety and persistent standing in line with SGSA [Sports Grounds Safety Authority] guidance," he added.
