Bonnie is depicted as an older kid in Toy Story 5 and is generally described as being around 8–10 years old.

Quick Scoop: How old is Bonnie in Toy Story 5?

Most recent coverage and early plot descriptions say that in Toy Story 5 Bonnie is no longer the little preschooler from Toy Story 3 and 4. In Toy Story 4, she was “around 5 years old,” but in the new movie she’s shown looking “significantly older,” with multiple breakdowns and commentary estimating her at roughly 9 or 10.

One official plot outline even directly calls her “a now eight-year-old Bonnie” as she becomes obsessed with a frog‑like tablet named Lilypad. Taken together, that places Bonnie in Toy Story 5 in the late–elementary range: about 8–10 years old, with 8 as the explicit in‑story age and 9–10 being how she visually reads in promo images and fan analysis.

So, if you’re writing, theorizing, or just arguing on forums about “how old is Bonnie in Toy Story 5,” the safest answer is: she’s written as 8, and she looks/feels like she’s about 8–10.
