12ft trampolines work well in large backyards. Always measure the area you use the trampoline. You do not want to return it after you have already started to assemble it. Also remember to include the clearance area around the outside of the trampoline. If you are purchasing a 12ft trampoline with and enclosure you only need to add a 2ft clearance area. However if you are interested in a trampoline without an enclosure (in-ground trampoline) you will need to add an additional 8ft clearance area.
No matter what size trampoline you buy, they all come with a weight restriction. 12ft trampolines come with a weight restriction of approximately 200lbs.
If you are would like to increase the size look at our 14ft trampoline.
