There is no official height limit for child passengers on air floated tubes in water parks or theme parks. The design and safety of the attraction typically dictate the recommended age, weight, and size limits rather than a specific height limitation.
In general, most inflatable raft rides have restrictions such as:
- Minimum age: 42 inches (107 cm) tall
- Maximum weight: usually not more than 250-300 pounds (113 to 136 kg)
- Recommended adult-to-child ratio: typically 1:2 or 1:3
However, these limits may vary depending on the specific ride or operator. It’s always best to check with the attraction directly for their rules and regulations regarding child passengers.
