I 2015, I set myself an ambitious slightly insane reading goal: 100 books.
My final count: exactly 100 books (from ~30 different series), totaling 38,048 pages. There were a few short stories in there (Pimpf by Charles Stross was the shortest at 25 pages) to offset a couple epic fantasies (1,048 pages in Brandon Sanderson's Words of Radiance). Overall, I averaged 388 pages/book, which sounds about right to me.
