What is the correlations between page count and file size of a PDF file?

Certainly the type of content that takes up the most space would be uncompressed raster images. Text and vector data - in general - take up very little space. However, there are caveats to all of that. Is compression being used for the data (any type) and if so, what kind? Lossy image compression (eg. JPEG) is good for some images but really bad for others. Are the fonts associated with the text embedded? And if so, are t subset or full embedded? What colorspace(s) are being used? CMYK and Spot color data (any object type) take up more space than RGB or Grayscale data. PDF also supports audio, video and 3D data - all of which can potentially be large when fully embedded or not compressed properly. And then there are all the non-visual things that can be present in a PDF that would take up space Metadata Structure & Semantic information Navigation aids etc. But at the end of the day - none of this is PDF specific. These are the same questions you would ask for Word or Keynote or EPUB or any other format. PDF just has lots more options for both increasing and decreasing file size.

Add Page Numbers to PDF: All You Need to Know

And it has to be big enough! In terms of the page count and the file size you see a strong correlation only between a content-rich PDF and the largest file size (300 MB in this case). And if you look at the PDF content-rich vs non-content-rich PDF side by side, the non-content-rich PDF has more pages with higher average content-content ratio and lower file sizes by a significant margin. How will the “pro-user” PDF compare? Let's say we have 2 PDFs (here we will use “pro-user” type for the PDF-type), they both have the same file size, type of content and markup but one is a 400 MB PDF and the other is a 200 MB PDF. The 200 MB PDF will have far less markup, and thus you can easily guess that that PDF was designed for a more “pro-user” user. The 400 MB PDF would have far.
