10ft trampolines are great for medium to large size backyards. Just measure the area you are planning to install it. Models that come with the safety enclosure require a 2ft clearance zone around the trampoline. If you are interested in a trampoline without an enclosure (perhaps an inground trampoline) you will need to add an 8ft clearance to the area. Just add the clearance area to the size of the trampoline when you measure the distance.
All models come with a weight restriction for the maximum capacity it is safely recommended for use. 10ft trampolines come with a weight restriction of approximately 175lbs.
If you are would like to increase the size look at our 12ft trampoline.
