The spacing of your pergola’s top runners is an aesthetic choice, and does not affect the stability of your structure. However, the further apart your runners are spaced, the less shade your pergola will provide.

Choosing your runners to be spaced 6" on center will provide a good bit of shade for your outdoor living space. One runner will be attached at the exact center of your pergola, and additional runners will be placed at 6" intervals on either side. Smaller spacing width will provide additional shade, but if even more shade is desired, consider adding a lattice top or retractable shade canopy.


Top Runner Sizes by Style:

• Vintage Classic - 2" x 2"
  
• Belvedere, Oasis, Arched - 2" x 4"
  
• Rough Cut - 3" x 6"
