1) Size of water slide you have room for.
2) Age group who will be playing on the inflatable water slide.
3) Number of people who will be playing and sliding on the inflatable.
4) Money, how much do you plan to spend on a inflatable water slide.
Many inflatable water slides fit most back yards but one huge problem is getting them into the back yard if that is were you plan to have your water slide. Be sure to ask the party rental company how big of a entrance (gate) to the back yard they need. Once you know how many people and there age groups are going to attend your party let the rental company know so they can suggest a good slide for you. The Bigger the water slide the more $ it will cost. Normally you can get a fair sized water slide rental for about $250. Bigger slides get expensive when they get taller than 14 Feet tall. Water slide rental prices grow expediently. For example you could get a 14 Ft tall waterslide for say $250 but a 18 Ft tall waterslide would cost about $350 and a 20 Ft tall water slide would cost about $450
