Oh, that question's trickier than it seems because it depends on so many variables outside just the word count. You've got font size, line spacing, margin widths—standard manuscript format with double spacing and 12pt Times New Roman is wildly different from a mass-market paperback's tight layout.
I recently formatted a manuscript that hit just over 5k words, and in a standard Google Doc with default margins and single spacing, it came out to about 10 pages. But when I switched it to the submission format my publisher wanted—double-spaced, specific font—it ballooned to nearly 20. Seeing those two numbers side by side really drove home how meaningless 'pages' is without context.
The average for a published novel? If we're talking trade paperback, the kind you'd pick up at a bookstore, the industry uses a rough estimate of 250-300 words per page. That would put 5000 words in the ballpark of 16 to 20 pages. But that's a loose average; a dense fantasy novel with small type might squeeze in more, while a YA book with larger print and lots of dialogue could have fewer.
Honestly, unless you're working with a specific publisher's guidelines, I'd focus on the word count itself. That's the only consistent metric. Pages are just a container, and the size of that container changes depending on who's holding it.
