12x24 Pergola Kits

12x24 Refers to the Size of the Pergola's Roof

All of the pergolas featured on this page have a 12' x 24' pergola roof covered by shade purlins, not including the end caps on traditional-style pergolas (which extend 12 inches beyond  the ends of the 12' beams and the 24' rafters, unless you opt for flat end caps). So for all of the 12-foot by 24-foot pergolas on this page, the beams and shade purlins are all 12 feet long (as they run the 12-foot width of the pergola), and the rafters are 24' long (as they run the 24-foot depth of the pergola), not including end caps.

Post Placement for 12x24 Pergolas

The posts (i.e. columns) of a traditional 12' x 24' pergola can be placed anywhere from 0" to 36" in from the outside edges of the beams and rafters (not including the 12" 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 10 feet apart width-wise and 22 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 12x24 pergolas (which never have overhangs), the posts are always in the corners. So for modern pergolas, the outside edges of the posts will be 12 feet apart width-wise and 24 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 12 feet by 24 feet. Using a basic circular saw or miter saw, you can cut any of the pieces down to the exact length required. Thus, the 12x24 pergolas on this page can easily be turned into 11.625-foot by 23.75-foot pergolas (or whatever specific dimensions you need).

Reminder: Width & Depth Are Not Interchangeable

Please be careful when ordering your pergola. A 12x24 pergola is not the same as a 24x12 pergola.

The attached 12x24 pergolas on this page will attach to your home on the 12' side and come 24' out from the wall. For free-standing 12 x 24 pergolas, the shade purlins (which create shade underneath the pergola) must run the 12-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 12-foot width side. If your evening sunlight will come from the 24-foot side, you'll want one of these 24x12 pergolas instead.
