I just decided to use the Flesch-Kincaid metric for all my unpublished novels, and they all have a 5th Grade Reading Level. Is this good? I remember doing some final revisions of them all and I think the reason for the low grade level is because of my shortening of sentences. But my question to you all is this, should authors strive to edit their works so they can be understood by 5th and 6th Graders?
That just means you use more short words than longer words, and have shorter sentences, right? In an of itself, that is not enough information to determine whether a story is worth reading or not for adults. You do you! If you're concerned about it, look for places where you could be clearer if you used more specific wording (which may be harder to read for school children)
