Somewhat off topic, but can stacking books like this damage them?

I have OCD and this is probably a stupid question, but I’ve been trying to re-organize my bookshelf and wasn’t sure if stacking heavy books horizontally or leaning them vertically (such as on the bottom shelf) could cause any damage? With smaller / paperback books I figured it’s not a big deal, but I have some pretty large and heavy ones.

This is what I’m working with if anyone has suggestions. I have some even bigger coffee table books that I’m trying to figure out what to do with but I was afraid stacking too many horizontally could compress the spines.

Sorry if this isn’t the most relevant place to ask, but r/books required community karma to make posts, and this was the only other literary focused subreddit I found when I searched. I didn’t really know where else would make sense.
