It was an expectable result that the scrolling behavior also increased significantly with a larger text size. But in addition, this had no effect on the reading speed needed to go through the passages of text. This leads to the question if the additional work needed to scroll through the texts removes a performance gain of a larger text size. Another possible reason for not improving the performance of reading by adjusting text size might be, that with a larger text size only a very small number of words could be put within one line of text. This makes the passages of text less readable, which was pointed out by some participants and corresponds to [19].
