Memoir vs autobiography: what is the difference?
By the Notre Livre editorial team · · 6 min read

The words are often used as if they meant the same thing, and bookstores do not always help. But if you are thinking about writing your own story, or giving one to a parent, the difference matters: it shapes what you include and how the book reads.
The short answer
| Autobiography | Memoir | Biography | |
|---|---|---|---|
| Who writes it | The person themselves | The person themselves | Someone else |
| Scope | The whole life | A theme, period or relationship | The whole life |
| Order | Mostly chronological | Organized by theme or story | Mostly chronological |
| Focus | Facts and events | Emotion, meaning, reflection | Facts, context, research |
| Tone | Record | Story | Portrait |
What is an autobiography?
An autobiography covers a life from the beginning, often starting with family origins and childhood and moving through education, work, marriage and later years. Its ambition is completeness: a record of what happened, in the order it happened.
It is the classic form for people whose public life is the point, but it also makes sense for a family history, where children and grandchildren want the full picture.
What is a memoir?
A memoir chooses. It might be about growing up on a farm, about a career in the Navy, about caring for a spouse, or about a single decade that changed everything. It reads more like a novel, with scenes, dialogue and reflection on what those years meant.
Because it is selective, a memoir is often easier to write and more pleasant to read. It is also more forgiving: you do not need every date, only the moments that matter.
Which one should you write?
- Choose an autobiography if you want a complete record for your family, from your parents' origins to today.
- Choose a memoir if one part of your life carries the story, or if you want the book to read like a novel.
- Choose a biography, or a tribute book, if you are telling the life of someone else, such as a parent or grandparent.
Many family books sit in between: a life told in order, but with the warmth and scenes of a memoir. That is the approach of our life story book, built from a guided conversation period by period. To tell the life of someone else, see the memorial and tribute book.
Famous examples
Well-known memoirs include Tara Westover's Educated, Michelle Obama's Becoming and Frank McCourt's Angela's Ashes: each is built around a particular story rather than a complete record. The Autobiography of Benjamin Franklin is the classic example of an autobiography that sets out to cover a life in order.
