24x12 Refers to the Combined Inner Dimensions of the 2 Roof Openings

When we say a pergola's dimensions are 24x12, 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 12' deep and which combine to be a total of 24' 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 12' deep or one 12.5' and one 11.5' deep or one 13' and one 11' deep or any other combination that adds up to 24 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 24' x 12', you would need to:

  • Purchase two sets of two posts totaling 24 feet to be the beams running the 24-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 12-foot posts to be the beams running the 12-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

24' x 12' pergolas are different from 12' x 24' pergolas. The wall-mounted pergolas on this page will attach to your home on the 24' width side and come 12' out from the house wall. For free-standing pergolas with a slatted roof, the roof rafters will be mounted to the 12' beams and run the 24-foot width of the pergola (providing more shade when the afternoon/evening sunlight comes from the 24-foot width side). If your afternoon/evening sunlight will come from the 12-foot side, you'll want a 12x24 pergola instead.
