Hi so i am writing a story and I would like to know how many lines of texts are you all comfortable with reading?
If you mean coding lines, without CC , 3000 - 4000 lines is perfect for 15 - 20 minute readable episode.
But it also depends how much you want to discuss/ show in the plot of each episode. Make sure it to ended with cliffhanger where required in episode to make your reader curious about what will happens next. or simply make your reader binge with your story with a lot of curosity.
But again depends upon on you what you are writing.
Just write How much you prefer. There is no end line in your story yet.
I hope it helps.
