10 Best Trampolines Sizes 2026 in the United States

The JumpFlex Hero 14-foot Round Outdoor Backyard Trampoline is designed for family fun, accommodating both kids and adults. It supports a wide range of weights from 40 to 200 pounds, with a maximum user weight of 550 pounds, making it suitable for multiple users at once. The trampoline has a 14-foot diameter and a round shape, providing ample space for jumping and performing flips and spins safely. The trampoline's frame is made of high tensile alloy steel, ensuring durability and stability. Additionally, it features 96 high-quality springs that contribute to an extraordinary bounce, allowing for smooth and high jumps.

Safety is a priority with the 360-degree net enclosure that securely clips to the mat, and a safeSeal system ensures there are no gaps or holes, preventing accidents. The included ladder makes it easy for users to enter and exit the trampoline. Assembly is straightforward, requiring no bolts or welds, which simplifies the setup process. The 10-year warranty is a testament to the product's durability and the manufacturer's confidence in its quality.

One potential drawback is the trampoline's size, as it requires a minimum yard space of 16.4 feet, which may not be suitable for smaller backyards. Additionally, the product's heavy weight (260.2 pounds) might make it challenging to move. The JumpFlex Hero trampoline is a high-quality option for families seeking a safe and enjoyable outdoor activity.

The Zupapa 16FT trampoline is a solid choice for families wanting a durable and safe outdoor trampoline. Its round shape with a spacious 16-foot diameter offers plenty of jumping room for kids and adults alike. The standout feature is its impressive weight capacity—supporting up to 1800 lbs static and 550 lbs dynamic—thanks to a double-layered alloy steel frame. This means it can easily handle multiple jumpers or heavier users without worry. The frame uses hot-dip galvanized steel, which resists rust and adds to long-term durability. With 108 springs included, the trampoline should provide a good bounce, and the no-gap safety design cleverly connects the jumping mat directly to the safety net, preventing common injury risks from spring gaps. The curved poles for the enclosure net are placed outward, which makes the jumping area safer by reducing chances of collision. Assembly is user-friendly with snap-button and screw-free parts, so setting it up won’t be a major hassle. Extras like adjustable basketball hoops add an element of fun for a range of ages.

The trampoline is quite heavy (226 pounds), meaning it may need two adults to move or assemble it comfortably. Also, while the weight capacity is strong, the actual number of springs (108) is moderate for a 16-foot trampoline, which could affect bounce quality for very heavy or very active jumpers. This trampoline is best suited for families looking for a safe, sturdy, and spacious option that prioritizes safety and durability with a long warranty backing.

The JumpSport 350 PRO is a 39-inch round indoor trampoline designed primarily for adult fitness use. Its size offers a generous jumping surface, making it suitable for various workouts, from personal exercise to small group sessions. The frame is made of durable alloy steel, promising long-lasting stability and strength. Supporting up to 300 pounds, this trampoline fits most adult users comfortably.

Instead of traditional metal springs, it uses 36 adjustable bungee cords, which provide a smooth, quiet, and cushioned bounce. This feature also allows you to customize the firmness of the mat with seven tension settings, giving you control over the bounce intensity depending on your workout needs. The no-tip arched legs enhance safety by keeping the trampoline stable during vigorous exercises. Weighing about 22 pounds, it is fairly portable but mainly designed to stay in one place during use.

While it lacks a spring system that some trampolines use, the bungee cords reduce noise and joint impact, which is great for indoor use and sensitive knees. Some users might find the 39-inch diameter a bit small if they want more room to jump freely, but this size fits well in tight spaces. This trampoline serves as a solid choice if you want a reliable, adjustable, and quiet rebounder for fitness workouts at home.
