Question

Splitting PDF by file size - files too small

I have a 120 MB document where each page is ~3 KB. When I attempt to split the document into 20 MB documents, I should be getting 6 parts. Instead, Adobe is making 50+ parts with only 1 page of about 3 KB size. When I try to split by number of pages, each part is still 119 MB. There are no images, only text, and each page is consistently 3 KB. I was able to Save as reduced size PDF and then managed to split, but how can I split properly going forward?

You can't know in advance what's the size of each page. It's not <File size of the original file> * (1/<Number of pages in the original file>), as there are often shared resources between the pages, such as image streams for fonts, which get duplicated when you split the pages. So if the original file contained a font that's 10MB, each one of the split pages will also need a copy of that 10MB font.

I'm not guessing in advance. The individual pages are 3 KB each when split.

OK, I didn't understand that's the case.
