i think you can compare the size of the stage with the phillipshalle in dusseldorf. i think about 60-70 people fit in one row. but the people that are actually standing in front of the stage, not on the side and the speakers, is probably a number of 40-50. but it's a pretty wide stage and it's only my guess, probably even more, been there twice, so i can't tell it 100 %.
