I am using this 3-ring binder to scrapbook all my OLD photographs of ancestors, many of which are thick. I've also included several booklets with genealogy information (I have put them inside the page protectors). Therefore, my pages aren't flat as a "normal" scrapbook would be. So I don't know if my answer is helpful. At the moment I have 15 pages completed, and the binder isn't completely full. I'm hoping to be able to add more before I'm done. I would guess it will hold perhaps 30 - 45 pages of flat content, maybe more.
