My typical scenes range from about 1500-3000, depending on what i want to accomplish. I read once in a blog from Jacqueline Lichtenberg, that every scene should be around 750 words, or by the 750 word mark, something changes within the scene. I went back one day to take a look at mine with this in mind and wouldn’t you know, she’s right. By 750ish a development happens or someone else comes in, or an setting changes within the ‘scene’. Since I’ve been aware of this, I feel like my scenes are tighter.
