How Much Room It Needs

The unit itself covers 142 by 33 feet. Rental companies also leave open space around every side for stakes, the blower tube and a safe exit, so measure your yard larger than the footprint. Check the maker sheet for the exact clearance it asks for.

Solid shape is this unit at 142 by 33 feet. Dashed shape is the middle size for its type, 34 by 19 feet. The bar is a 6 foot adult.
