It's 48-in L x 48-in W x 80-in H (122-cm L x 122-cm W x 203-cm H). 

The tent also has several vents, all of which, are kept completely closed.

Underneath the tent is a garage mat.  Since the tents are sewn together, the seams can leak just slightly.  An absorbent garage mat captures any water that might leak through the seams to prevent damaging the floor. These mats can be found in various sizes on Amazon or at Home Depot.

Plastic hardware cloth is attached to the frame of the tent with zip ties. Wire or plastic covered wire mesh is too heavy and more expensive.
