How many children will fit into a standard 13×13 or 15×15 castle bounce?
This of course depends on the size and age of the children. But generally speaking, for children between the ages of 3 and 7, you can generally fit 5 to 9 children in a 13×13 castle bounce, and 8-12 children in a 15×15 castle bounce. For children between the ages of 8 and 12, you can generally fit 3 to 7 children in a 13×13 castle bounce, and 6 to 10 children in a 15×15 castle bounce.
