18x14 Refers to the Combined Inner Dimensions of the 4 Roof Openings

When we say a pergola's dimensions are 18x14, we are referring to the combined inside dimensions of the 4 roof openings (from inside-edge to inside-edge). All of the kits featured on this page are meant to have 4 roof openings, arranged in a 2x2 grid, which combine to be a total of 18' wide and a total of 14' deep.

The overall outside-edge to outside-edge dimensions of the pergola will be:

With all of this being said, you can easily change the overall size of your pergola by trimming the wood posts that you plan to use for the roof beams. For example, if you wanted the true outside-edge to outside-edge dimensions of a free-standing pergola to be exactly 18' x 14', you would need to:

  • Purchase three sets of two posts totaling 18 feet to be the beams running the 18-foot width, and then cut off a total of 14.6 inches (for 4x4 wood posts) or 22.6 inches (for 6x6 wood posts) per set of two posts; and
  • Purchase three sets of two posts totaling 14 feet to be the beams running the 14-foot depth, and then cut off a total of 14.6 inches (for 4x4 wood posts) or 22.6 inches (for 6x6 wood posts) per set of two posts

Reminder: Width & Depth Are Not Always Interchangeable

18' x 14' pergolas are different from 14' x 18' pergolas. The wall-mounted pergolas on this page will attach to your home on the 18' width side and come 14' out from the house wall. For free-standing pergolas with a slatted roof, the roof rafters will be mounted to the 14' beams and run the 18-foot width of the pergola (providing more shade when the afternoon/evening sunlight comes from the 18-foot width side). If your afternoon/evening sunlight will come from the 14-foot side, you'll want a 14x18 pergola instead.
