It depends on what type of writing you are doing. For example, an academic paper or a research paper may need longer chapters while a blog post or a shorter story may need shorter chapters.
Here are some things to consider when deciding if a 10,000 word chapter is too long:
How much content are you including in the chapter? If you are writing a fiction work with a lot of action, a 10,000 word chapter could be quite suitable. However, if you’re writing a thesis or research paper with a more content-heavy approach, you may need to break up your chapter into several smaller, more digestible pieces.
What is the purpose of the chapter? If the chapter is meant to provide an argument or advance the story in a meaningful way, then a 10,000 word chapter may be appropriate. If the chapter is more of a scene-setting or exposition piece, then a shorter chapter may be more suitable.
Who is the audience for the chapter? If you’re writing for a professional audience, or an audience with a certain level of expertise, then a 10,000 word chapter could be appropriate. If you are writing for a wider general audience, then you may want to shorten your chapter length.
Are you writing in a novel, blog, or other format? Novels often require longer chapters, while blog posts and other similar formats require shorter chapters.
Ultimately, it depends on the specific format and purpose of your writing. There is no hard and fast rule for how long or short a chapter should be, so you may want to experiment with different lengths and see what works best for your particular project.
