I honestly like converting units of measurement into something immediately and viscerally understandable in situations like these. Like, yeah, I can understand that 2100 feet or 650 meters worth of paper is a lot, but that’s all I think about it; it’s big enough that I just default to the general “a lot” in my head. But when you say 2 Eiffel Towers, I immediately picture myself looking up at the Eiffel Tower with 2 huge stacks of paper towering next to it, which makes me feel very different about the amount of pages.
