What age did Hermione get pregnant?

The timeline of Hermione Granger's family life

When diving into the expanded lore and official epilogue of the Harry Potter series, fans often look closely at how the characters' lives panned out after the defeat of Voldemort. A common point of curiosity is the timeline of Hermione Granger and Ron Weasley's family, particularly regarding when they welcomed their first child.

According to the canon timeline established in the epilogue—which jumps nineteen years forward—Hermione and Ron's oldest child, Rose Granger-Weasley, is eleven years old when she starts Hogwarts. Based on this calculation and their birth years, Hermione was approximately 25 to 26 years old when she became pregnant with and gave birth to Rose.

Rather than starting a family during their immediate post-Hogwarts youth, Hermione and Ron spent their early twenties establishing successful careers in the wizarding world. Hermione notably took her education seriously, returning to Hogwarts to complete her final year before diving into a high-achieving career at the Ministry of Magic. By the time they welcomed their children, they were well-settled into adult life.
