I'm writing a YA sci-fi/post apocalyptic type novel with two view point characters. The book is all written in third person and so far every time I switch between view point characters use a chapter break. For most of the book, the two view point characters are together experiencing the same situations (though they are experiencing them very differently). Because of this, I feel that a chapter break is a good way to make it clear that our view point character has changed. The thing I'm worried about is chapter length. I've had some chapters that are almost 5000 words but then I have others that are just under 1000. I know that word count per chapter can be played with a little to adjust the pacing of the novel. Occasionally I find a point 700 words into a chapter that I think would be a perfect time to switch view point characters I just want to make sure that my chapters aren't too short because of it.
If the majority of my chapters are on average 3500 words, is an occasional 700 word chapter going to throw off the flow of the novel or cause any disruption?
