How many people can go on a 12 feet or 13 feet trampoline at once?

A 12-foot trampoline can typically accommodate 2 to 3 people at once, while a 13-foot trampoline may safely hold 3 to 4 people, depending on their combined weight and the trampoline's weight limit. It's important to follow the manufacturer's guidelines for safety, as jumping with too many people can increase the risk of injury. Always ensure that jumpers are of similar size and weight for added safety.
