Dormer was born in Reading, Berkshire. She is of part Norwegian ancestry. Dormer attended Chiltern Edge Secondary School before moving to Reading Blue Coat School, historically an independent boys' school that admits girls in the sixth form. She grew up with her stepfather (a builder), mother, sister Samantha, and brother Mark. She has said that she was the victim of bullying while at school, but "still to this day [she] can't place why". At school, Dormer was head girl, a first class student, vice-captain of the school netball team, and travelled the world with her school's public speaking team.
During her school years, Dormer trained in dance at the Allenova School of Dancing. She describes herself as the "academic hopeful" of the family and was provisionally offered a place to study history at Cambridge; but, in her A-level History exam, she did not achieve the A grade she needed to attend. Dormer decided she would audition for drama schools and decided to train at the Webber Douglas Academy of Dramatic Art in London. Since 2011, Dormer has been engaged to Anthony Byrne, whom she met in Dublin while filming The Tudors in 2007. Dormer has stated that Cate Blanchett has been an influence in her career as an actress.
