Understanding Sizing Measurements

  • Unit Size: This is the manufacturer’s listed size of the inflatable, showing the minimum flat grass space required. Example: A 12ft x 12ft bouncy castle will need a 12ft x 12ft grass area for safe setup. For full dimensions, see the size tab on each product listing.

  • Required Space: This refers to the overall clear space needed for safe operation, free from obstacles. Example: A 12ft x 12ft castle that requires 16ft x 16ft means you’ll need the 12ft x 12ft base area plus 2ft of clear space on every side, away from walls, fences, washing lines or posts.
