20x10 Refers to the Combined Inner Dimensions of the 2 Roof Openings

When we say a pergola's dimensions are 20x10, we are referring to the combined inside dimensions of the 2 roof openings (inside-edge to inside-edge). All of the kits featured on this page are meant to have 2 roof openings that are both 10' deep and which combine to be a total of 20' wide. (Note: If you choose a kit made for a slatted wood roof, the combined width of the 2 roof openings can be divided any way you'd like: both 10' deep or one 10.5' and one 9.5' deep or one 11' and one 9' deep or any other combination that adds up to 20 feet.)

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 20' x 10', you would need to:

  • Purchase two sets of two posts totaling 20 feet to be the beams running the 20-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 10-foot posts to be the beams running the 10-foot depth, and then cut off 7.3 inches (for 4x4 wood posts) or 11.3 inches (for 6x6 wood posts) from each one

Important Note: Our shade canopies are specifically designed to fit roof openings that are exactly 8x8, 8x10, 8x12, 10x10, 10x12 and 12x12. If you're purchasing a kit with shade canopies, you cannot trim down the roof beam posts. Furthermore, all roof posts must be 8-, 10- or 12-foot lengths.

Reminder: Width & Depth Are Not Always Interchangeable

20' x 10' pergolas are different from 10' x 20' pergolas. The wall-mounted pergolas on this page will attach to your home on the 20' width side and come 10' out from the house wall. For free-standing pergolas with a slatted roof, the roof rafters will be mounted to the 10' beams and run the 20-foot width of the pergola (providing more shade when the afternoon/evening sunlight comes from the 20-foot width side). If your afternoon/evening sunlight will come from the 10-foot side, you'll want a 10x20 pergola instead.
