The standard height requirement for most Ferris wheels is 36 inches (91 cm) or taller. Since the child in question is only 1 meter and 1 centimeter tall, which is approximately 37.8 inches, it seems they could potentially fit on a regular Ferris wheel.
However, please note that individual amusement park guidelines may vary depending on factors such as ride safety regulations and accessibility accommodations for children with disabilities. It’s always best to check directly with the specific theme park or carnival operator regarding their height restrictions before attempting to let young children (like this 4-year-old) take a spin!
