What is the difference between memoir and autobiography?
- Memoir: 60,000-90,000 words, focused theme or period.
- Autobiography: 80,000-150,000+ words, full life from birth.
- Memoir written by anyone with a story; autobiography typically by notable figures.
- Memoir is literary (narrative arc); autobiography is historical (chronological).
- First-time writers almost always write memoir, not autobiography.
A memoir focuses on a specific theme, period, or experience in the author’s life (60,000-90,000 words), while an autobiography covers the author’s entire life comprehensively from birth (80,000-150,000+ words). Memoirs are literary works built around a narrative arc; autobiographies are historical or political accounts typically written by famous figures.
Chapter i·Why it matters
First-time writers often pitch "autobiographies" that are actually memoirs in scope. Agents and editors use the terms precisely: memoir for thematically-focused life writing; autobiography for comprehensive life narratives by notable figures. Knowing which one you are writing positions the book correctly for its actual market.

Chapter iii·Example
A first-time author drafting her "autobiography" pitches it to literary agents. Agents pass — they correctly identify it as a memoir (focused on her decade as a war correspondent, not her whole life). She repositions as memoir, queries memoir-focused agents, and signs within six months. The book sells to a major imprint.
