How do I write a middle grade novel?

By the WriteLoom editorial teamUpdated 2026-09-02
Key facts
  • Middle grade runs 20,000 to 55,000 words depending on genre and age band.
  • Protagonists are usually 10 to 13, at the top of the readership's age range.
  • Romance is minimal; friendship, family, and identity carry the emotional weight.
  • Interiority is present but concrete, expressed through action more than reflection.
  • The adult world exists at the edges; children solve the problem.
Direct answer

Middle grade runs 20,000 to 55,000 words for readers eight to twelve, with a protagonist usually 10 to 13. The emotional register is friendship, family, and figuring out who you are, not romance. Adults can exist but cannot solve the problem, and the story's stakes should feel total from inside a child's world.

Chapter i·Why it matters

Adults writing middle grade often write nostalgia: a story about childhood rather than one inside it. The difference is perspective. A missed birthday party is not small to an eleven year old, and treating it as small, even in the narrative voice, is the fastest way to lose a middle grade reader and an editor.

Chapter ii·What to include

  • A protagonist at the top of the age range, 11 to 13 for older middle grade.
  • Stakes that are total inside the character's world, not objectively large.
  • Friendship and family as the primary emotional engine.
  • Adults present but structurally unable to fix it.
  • Voice that respects the reader without talking down or up.
  • Chapter lengths short enough to keep momentum, generally under 2,500 words.

Chapter iii·Example

A writer's middle grade opened with a parent explaining the family's financial trouble. Rewritten so the protagonist figures it out from a cancelled subscription and a whispered phone call, the same information arrived as story rather than briefing.
