It seems you may be making assumptions that the formatting and typesetting of any particular edition were intentional or even deliberate on the part of the author, not any number of people, from editors to printers, who could and would have influenced those things for various reasons.
Something I am rather familiar with is brought out by your mention of the German edition/title; that the continental market seems to generally produce books that are far more densely formatted, i.e., smaller font and typesetting, thinner pages, and leading to overall tighter book formats. I actually appreciate it when, e.g., a book is 1/2 the size and weight, and usually also made far more durably; but it will invariably compromise any author intention related to the arrangement of the lettering.
Maybe you can confirm that based on what seems to be your English and German editions of the same novel.
