The smallest Stretch tent is 20x13 feet (6x4 meters).
This sized does not require center poles. If the center mounts were 10-20 inches higher than the sides of the awning, this would be enough for water drainage.
The small size has a number of advantages: low weight of 24 pounds, small bag volume, and will even fit in a micro car.
This size is ideal for family picnics and outdoor adventures.
