What matters most

Because the specs match, this is purely a size-and-space decision. The 12ft is about $849; the 14ft is about $899, so the price difference is small. The 14ft gives meaningfully more jumping room, which helps when two kids share the mat, but it also needs more clear space around it. If your yard is tight or only one child will use it, the 12ft is the sensible pick; otherwise the small step up to the 14ft is easy to justify.
