The question of how many sittings Charles had is difficult to arrive at. The church had three galleries in addition to its pews. The church is approximately half the size of St Andrew's. A figure of 900 sittings is given by the one author in 1977 although this is not clear whether or not all the galleries were taken into account. Charles Church was popular and may have been full that morning. Nationally there were a large number of absences on that day so we must presume that the church could seat over 1,000 perhaps 1,200.
