12×16 Pergola Plans

This step by step diy project is about 12×16 pergola plans. This outdoor pergola has a base of 12×16, while the roof is 14×18. I have designed this free plans for the free standing patio pergola, so you can create some shade in the backyard for a sofa or even a dining table with a few chairs. Take a look over the rest of my woodworking plans, if you want to get more building inspiration.

When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in about a day.

How to build a 12×16 pergola

Fitting the posts

Fitting the posts

The first step of the 12×16 pergola project is to layout the posts. Use batter boards and string to layout the location of the posts. Apply the 3-4-5 rule to every corner and then measure the diagonals to make sure they are perfectly equal. You need to make adjustments until you get the desired result.

Anchoring the posts of the anchor

Anchoring the posts of the anchor

There are a few ways to secure the 6×6 posts into place. You can set the posts in concrete or you can use adjustable anchors and pour footings. Dig the holes 3′ deep (or under the front line) and about 12-13″ in diameter. Compact a layer of gravel to the bottom of the holes and then fit the tube forms. Fit the posts, align them and plumb them with a spirit level. Fill the forms with concrete, while the posts are locked into place with temporarily braces. If you use anchors, you need to align and set them into concrete. Fit the posts after the concrete dries, using lag screw.

Smart tip: Read the local building codes, so you dig the holes at the appropriate depth.

Building the support beams

Building the support beams

Use 2×8 lumber for the support beams. Make decorative cuts to both ends of the beams. You can use a large circular item so you can draw the curved lines. Get the job done with a jigsaw and then smooth the edges for a neat result.

Fitting the supports beams

Fitting the supports beams

Fit the support beams to the top of the posts. Use a spirit level to plumb the support beams and then clamp the beams into place tightly. Drill pilot holes through the beams and through the posts. Insert the 9″ carriage bolts and then tighten the nuts.

Building the rafters

Building the rafters

Use 2×6 lumber for the shade elements. Make the curved decorative cuts to both ends of the beams. Mark the cut lines and then get the job done with a saw. In addition, you need to make a few 2″ deep notches, so you can fit the shade elements to the support beams.

Mark the cut lines on the beams and then use a circular saw to make parallel cuts. Use a chisel to remove the excess and then smooth the recess with sandpaper. When cutting both ends of the rafters you can choose from more templates, so make sure you choose the design that suits your needs.

Fitting the shade elements

Fitting the shade elements

Fit the shade elements to the support beams. Place the shade elements equally spaced and then lock them into place with rafter ties. Alternatively, you could drill pilot holes through the shade elements (above the notches) and insert 5 1/2″ screws so you can lock them into place tightly.

Braces

Braces

The diagonal braces are needed if you live in a windy area. Moreover, these braces have a decorative effect on the pergola, adding value to the project. Make 45 degree cuts to both ends of the braces. Moreover, use a jigsaw to make the curved cut to the braces and smooth the edges with 120-220 grit sandpaper.

Fitting the braces

Fitting the braces

Fit the braces to the sides of the pergola. Align the edges drill pilot holes and insert 4 1/2″ screws to lock the braces into place tightly.

Fitting the top slats

Fitting the top slats

Fit the 1×2 slats to the top of the pergola. Place these slats equally spaced for a professional result. Center the slats to the rafters and then drill pilot holes, before inserting the 1 5/8″ screws.

Last but not least, you need to take care of the finishing touches. Therefore, fill the holes with wood putty and then smooth the surface with 120-220 grit sandpaper. You can also fit braces, if you live in a windy area. Apply a few coats of paint or stain over the components, to enhance the look of the pergola and to protect the components from decay.

    Is there anyway you could send me a pdf file that I can download and print for the 12 X 16 pergola? Thank you in advance.

    Hey! This may be a super stupid question but I cannot find 1″X2″X18′ pieces of wood (or longer to cut down) for the slats. I’ve looked on Home Depot and Lowes sites and googled it in general and found no results at all. Can you advise on a place to buy this size? Or do you cut them out of a bigger piece? Please let me know as this is the exact size I’m looking to build! Thanks for sharing!

      If you can’t find then at 18′, then you can use two pieces of 10′ slats. Make sure the joint is on the middle of the rafter.
