For me, it depends on the genre. Teen fiction definitely is more geared for shorter chapters. I think fantasy readers are more ‘trained’ so to speak for longer parts (world-building being a big factor).
When I write mystery/thriller, my chapters tend to be a lot longer, sometimes up to 4k words long, but because there’s a lot of action and it’s fast paced, I don’t think they feel as long. So pacing, genre, and audience are big factors on the right length for a chapter.
Also consider, on Wattpad in particular, that if you had two novels of the same word-count, but one had shorter chapters and one longer, the book with shorter chapters will register more reads, even if they had identical number of readers, because reads are registered per part.
