In the traditional publishing world, word count for young adult novels is all over the place. The Twilight Saga books are each over 100,000 words. Books like Kate Brian’s Private series are more around the 65,000-75,000 word count. Most websites and agents place a typical YA manuscript between 45,000-80,000 words. Here is what Agent Colleen Lindsay says about YA:
YA fiction = For mainstream YA, anywhere from about 45k to 80k; paranormal YA or YA fantasy can occasionally run as high as 120k but editors would prefer to see them stay below 100k. The second or third in a particularly bestselling series can go even higher. But it shouldn’t be word count for the sake of word count.
According to wikipedia, a novelette is between 7,500 and 17,499 words. A novella is generally anything between 17,500 and 40,000 words. Anything over 40,000 words is technically a novel. However, it seems like internet opinions on the different types of novels is all over the place. Some people think that anything below 70,000 words is not a novel. The first book in my Peachville High Demons series, Beautiful Demons, comes in just under 47,000 words, so technically, it should be considered a novel, just on the low end of a typical YA novel. Each subsequent novel in the PHD series is slightly longer with Book 2 just over 50,000, Book 3 just over 54,000, and Book 4 around 60,000 words.
