What age are the books for?
Updated 17 August 2026
Once Books makes picture books for young children — roughly toddler through early primary. You pick an age band when you create a book, which tunes the reading level and how much text sits on each page.
The format is a classic illustrated picture book, so it suits the ages that picture books always have — from a bedtime story for a toddler to an early reader following along. The age band you choose sets the reading level and the amount of text per page, so the book fits the child rather than the other way round.
