Memoir vs autobiography: the usual difference, why it matters less than you think, and how to choose for your story
The usual rule: an autobiography tells the story of a whole life, mostly in order, and a memoir tells the story of one part of a life. Both are true stories told in the first person. Here are the differences people list, examples of each, why the line is blurrier than it looks, and how to decide what to write.

What they have in common
Both are written in the first person, the "I" voice, and both are based on things that really happened. Wiktionary defines an autobiography as "the story of one's own life," and its first definition of memoir is simply "an autobiography." So in dictionary terms, a memoir is a kind of autobiography.
The differences people list
| Usually said about | Autobiography | Memoir |
|---|---|---|
| How much of the life | The whole life, from childhood to the time of writing | One period, relationship, place or theme |
| Order | Mostly chronological | Can move back and forth in time |
| Focus | Events and facts | Feelings and what the experience meant |
| Who writes it | Often said to be famous people | Anyone |
These are the distinctions commonly made; Scribe Media's article on the question argues each one falls apart under a closer look (see below).
Examples of each
- The Autobiography of Benjamin Franklin (written 1771 to 1790). Franklin's own record of his life, left unfinished. The book now sold as his Autobiography is one he seems to have called his Memoirs, which says a lot about how loose the labels are.
- Narrative of the Life of Frederick Douglass, an American Slave (1845). Douglass's life in slavery and his escape, written as a memoir and an argument for abolition.
- The Story of My Life, Helen Keller (1903). Her early life, especially her years with her teacher Anne Sullivan.
- I Know Why the Caged Bird Sings, Maya Angelou (1969). Her childhood and youth, the first of seven volumes about her life: a clear case of a memoir, one period per book.
- Educated, Tara Westover (2018). An isolated childhood in rural Idaho with no formal schooling, through to a PhD at Cambridge. A memoir built around one change.

Why the labels overlap
Scribe Media's article What's the Difference Between a Memoir and an Autobiography? takes a strong position: there is no real difference. Its points, in short:
- No book covers an entire life. Every autobiography leaves things out, so "the whole life" is a matter of degree.
- Fame is not a genre. Every person's life is important, and everyone has a story to tell.
- Order should serve the story. Tell it in the order that makes the most sense and is most interesting to the reader.
- Facts alone do not hold readers. A list of facts is dull; what people read for is the experience behind them.
Its conclusion: readers do not care whether your book is a memoir or an autobiography. They care whether it is entertaining, helpful or enlightening.
How to choose for your story
- Name your reader. Your grandchildren, people facing what you faced, your industry. A small audience is still an audience.
- Decide what they should take away. Finish the sentence "By the end, my reader will understand ___."
- Pick the span that delivers it. If the takeaway needs your whole life, tell the whole arc. If it comes from one period or turning point, focus there and leave the rest for another book.
- Choose the order. Chronological is easiest to follow. Opening on a turning point and then going back can pull a reader in faster.
- Pick the label last. Whatever you call it on the cover, it does not limit what you can include.
Not sure where to start? Talking is often easier than typing. See how to write an autobiography for the full process, or life story interview questions to get your stories out loud first.
Start here: finish the sentence "My book is about ___, and by the end my reader will understand ___." If the blank covers your whole life, write the whole arc. If it covers one part, write that part.
Common questions
What is the difference between a memoir and an autobiography?
The usual answer: an autobiography tells the story of a whole life, mostly in order, and a memoir tells the story of one part of a life, such as a period, a relationship or a theme. Both are true stories told in the first person. In practice the labels overlap, and Scribe Media's view is that there is no real difference worth worrying about.
Is a memoir a type of autobiography?
Yes, in most dictionaries. Wiktionary's first definition of memoir is simply "an autobiography." A memoir is usually described as a narrower kind of autobiography, focused on part of a life rather than all of it.
Can a regular person write an autobiography?
Yes. Some people say autobiographies are only for famous people, but nothing about the form requires it. Anyone can write the story of their life, for their family or for a wider audience.
Should I write a memoir or an autobiography?
Start from your reader instead of the label. If they want the whole arc of your life, tell it in order. If one period or change matters most, focus on that. Either way, choose the stories that serve the reader and leave out the rest.
