Here are the reported story ages, birthdays, and heights for major Demon Slayer characters, with changes over the story labeled where relevant. The figures come from official fanbook materials and official anime character information; a missing age or birthday means it is not listed in the cited profiles.
These are story-era figures, not characters’ ages in 2026. Demon “ages” below refer to how long they had been demons, not necessarily their total chronological ages.
