Nonogram puzzles are commonly found on boards ranging from 5x5 to 25x25, although there’s no limit to their size.
The largest puzzle I’ve discovered that was published in a puzzle book and for which I could find a photo or video is this 45x45 puzzle. On Amazon, I’ve also seen books that claim to have puzzles with 60x60 boards, which I assume is reaching the upper limit of what you can comfortably cram into a printed book.
If we broaden our search to include digital puzzles, then one of the largest nonogram puzzles I could find is Japanese crossword #51237 on nonograms.org, which is an impressive 200x200!
