Well, the length of vows in a story varies. If it's a short and concise tale, vows might be just a couple of sentences. For a more elaborate story, they could stretch to a couple of paragraphs to convey the depth and significance.
There's no one - size - fits - all answer. A typical genre novel like a mystery or romance might be around 60,000 - 80,000 words. Literary novels can be shorter or longer. Young adult novels tend to be in the 50,000 - 80,000 word range. However, if you're writing for a specific publisher or market, they may have their own preferences regarding length.
The length of a story varies widely. For a children's story, it might be just a few pages. But for a complex epic, it could be several volumes. It all depends on how much detail and depth you need to convey your plot and characters.
It really depends. A short story might be a few thousand words, while a novel can be tens or even hundreds of thousands of words. There's no strict rule.
