Which trampoline size is best for you? If you plan to have more than two people jumping at one time, you’ll want a trampoline that’s at least 14’ in diameter. Most trampolines in the 10-12’ range can accommodate two jumpers at one time, but anything smaller is best reserved for a single jumper. Choose from trusted brands like Skywalker®, Springfree®, Jump Power® and Pure Fun®. You can also explore our selection of top-rated trampolines — each trampoline in this collection has received a four- or five-star rating from our customers.
