The Key Differences Between Middle Grade vs Young Adult

OK, class. What sets a middle-grade novel apart from a young adult novel? If you said MG is for readers ages 8–12, and YA is for readers ages 13–18, then give yourself a check plus. But if you’re writing for the juvenile market and that’s all you know about these two categories, then I’m afraid you still need to stick around for the rest of this class. A book that doesn’t fit within the parameters of either age category is a book you won’t be able to sell.
In my work with The Jennifer De Chiara Literary Agency, I see my inbox flooded every day with queries for manuscripts that suffer from an MG/YA identity crisis. Like when a query says, “I’ve written a 100,000-word MG novel about a seventh-grader who falls in love and has sex for the first time.” Or when one states, “In my 20,000-word YA novel, a 14-year-old holds her first sleepover and learns the meaning of true friendship.” Both queries would earn a swift rejection, based on both inappropriate manuscript lengths and on content that’s either too mature or too young for the audience they’re targeting. Sadly, by not understanding what makes a book a true MG or a solid YA, these writers have hamstrung their chances for success, regardless of how well written their stories may be. It’s like they showed up to a final exam without ever cracking a book.

One difference between middle grade and young adult is the age of your protagonist. But it is not the only one.
Mg At A Glance
Age of readers: 8–12.
Length: Generally 30,000–50,000 words (although fantasy can run longer to allow for more complex world-building).
Content restrictions: No profanity, graphic violence or sexuality (romance, if any, is limited to a crush or a first kiss).
Age of protagonist: Typically age 10 for a younger MG novel, and up to age 13 for older, more complex books.
Mind-set: Focus on friends, family and the character’s immediate world and relationship to it; characters react to what happens to them, with minimal self-reflection.
Voice: Often third person.
Ya At A Glance
Age of readers: 13–18.
Length: Generally 50,000–75,000 words (although there’s also a length allowance for fantasy).
Content restrictions: Profanity, graphic violence, romance and sexuality (except for eroticism) are all allowable (though not required).
Age of protagonist: Ages 14–15 for a younger YA with cleaner content aimed at the middle-school crowd; for older and more edgy YA, characters can be up to 18 (but not in college).
Mind-set: YA heroes discover how they fit in the world beyond their friends and family; they spend more time reflecting on what happens and analyzing the meaning of things.
Voice: Often first person.
MG vs. YA Characters
When picking your hero’s age, remember that kids “read up,” which means they want to read about characters who are older than they are. So an 8-year-old protagonist won’t fly for the MG category, though it’d be OK for a younger chapter book or easy reader. For the widest audience, you’ll generally want your protagonist to be on the oldest side of your readership that your plot will allow. That means a 12- or even 13-year-old hero for MG, and a 17- or 18-year-old for YA (just remember your hero can’t be in college yet—that would push it into the “new adult” category).
MG vs. YA Readers
Middle-grade is not synonymous with middle school. Books for the middle-school audience tend to be divided between the MG and YA shelves. So which shelf do those readers go to? While there is no such thing as a ’tween category in bookstores, there are degrees of maturity in both MG and YA novels that’ll appeal to the younger and older sides of the middle-school crowd. A longer, more complex MG novel with characters who are 13 could take place in middle school and be considered an “upper-MG novel.” But the material can’t be too mature. It’s still an MG novel, after all, and most readers will be younger. Writing a sweeter, more innocent YA? Then it’s pretty likely that your readers will be ’tweens, that your characters should be around 15 years old, and that your book will be marketed as a “young YA.”
While it’s useful for you to understand these nuances as you craft your story and relate to your true audience, when it comes time to submit, don’t go so far as to define your novel as upper MG or younger YA in your query. That’s already pointing to a more limited readership. Instead, just stick to calling it either MG or YA when you submit, and let an interested agent draw conclusions about nuances from there.
MG vs. YA Content and Voice
What’s cool to a fourth-grader differs from what a 10th-grader will idolize. Same goes for the way they speak and the way they view the world. Which is why if romance appears in an MG novel, it’s limited to a crush and maybe an innocent kiss, as it is in Shugby Jenny Han. A YA could involve deep, true love as well as sexuality, as in The Fault in Our Stars by John Green. Another key difference? Overall, MG novels end on a hopeful note, while YA novels could have less optimistic endings, as in Green’s tearful story. You could say that that’s youth vs. experience coming into play.
