What is a pergola beam span?


Answer by  joeinphilly (388)

The beam span is the length between the supporting posts. If you are building a 12' x 12' pergola using posts on the corners then the span is 12 feet.

A pergola is a type of raised gardening structure. The beams, which span between 15 to 20 feet in length between supports, can be as long as desired.
