The record attendance at the ground was 42,322, against Tottenham in an old Division One match on 17 October 1970, when the North and South Banks were terraced, as was the old "Chicken Run" at the front of the East Stand.

The Boleyn Ground became an all-seater stadium from the early 1990s because clubs had to meet new FA regulations for stadium safety after the Hillsborough Disaster in 1989.
The record attendance after Upton Park became an all-seater was 35,550, on 21 September 2002 for a Premier League match against Manchester City.
Before its closure, the ground had a total capacity of 35,016, all seated.

Upton Park had four main stands, the Sir Trevor Brooking Stand, Bobby Moore Stand, East Stand and Betway Stand.
