32x18 Pergola Kits

32x18 Refers to the Size of the Pergola's Roof

All of the pergolas featured on this page have a 32' x 18' pergola roof covered by shade purlins, not including the end caps on traditional-style pergolas (which extend 9 inches beyond  the ends of the 32' beams and the 18' rafters, unless you opt for flat end caps). So for all of the 32-foot by 18-foot pergolas on this page, the beams and shade purlins are all 32 feet long (as they run the 32-foot width of the pergola), and the rafters are 18' long (as they run the 18-foot depth of the pergola), not including end caps.

Post Placement for 32x18 Pergolas

The posts (i.e. columns) of a traditional 32' x 18' pergola can be placed anywhere from 0" to 36" in from the outside edges of the beams and rafters (not including the 9" end caps), as shown in this diagram. Most customers choose to place the posts 12 inches in from the ends of the beams/rafters as shown in this CAD drawing, which puts the outside edges of the posts 30 feet apart width-wise and 16 feet apart depth-wise. But again, you can position the posts anywhere from 0 to 36 inches in from the ends of the beams/rafters to create your desired overhangs. It's also worth noting that the overhang can be different on one side than it is on the other sides, if needed or desired.

For modern-style 32x18 pergolas (which never have overhangs), the posts are always in the corners. So for modern pergolas, the outside edges of the posts will be 32 feet apart width-wise and 18 feet apart depth-wise.

All Parts Can Be Trimmed Down to Your Desired Length

To make our pergolas as affordable as possible, we only manufacture the beams, rafters, purlin holders and shade purlins in 2-foot increments (or 4-foot increments above 20 feet). But one or both of the width/depth dimensions of your deck, patio or other outdoor space may be slightly shorter than 32 feet by 18 feet. Using a basic circular saw or miter saw, you can cut any of the pieces down to the exact length required. Thus, the 32x18 pergolas on this page can easily be turned into 31.625-foot by 17.75-foot pergolas (or whatever specific dimensions you need).

Reminder: Width & Depth Are Not Interchangeable

Please be careful when ordering your pergola. A 32x18 pergola is not the same as an 18x32 pergola.

The attached 32x18 pergolas on this page will attach to your home on the 32' side and come 18' out from the wall. For free-standing 32 x 18 pergolas, the shade purlins (which create shade underneath the pergola) must run the 32-foot width of the pergola. So to maximize the pergola's shade, you will want to orient the pergola such that the evening sunlight comes from the 32-foot width side.
