The size of the inflatable depends on the number of guests attending, their age, and size. Here are some examples. If you are hosting a party for children five years or younger, a 13x13 bounce house would be suitable. On the other hand, if you have teens attending your party, a 15x15 bounce house might fit better. For bounce house events with many guests, the size of the children may not matter. Even if the event is for small children, you should rent a larger unit that can accommodate more people. If you are hosting a water slide event for adults, renting a unit at least 18 feet tall is wise. A slip n' slide is another excellent option for adults. Smally kids can use our smaller slides or even combos units.  Please consider taking advantage of our mutable item discount. These discounts come in handy when you have a large guest list. Proper size inflatables at your event will ensure all your guests have an enjoyable time.
