Counts are for the standard layout shown in the product diagram. Choose lengths to suit your space.

When purchasing your lumber, always take a bracket with you to ensure a proper fit.
You can select whatever lumber suits your style and budget. It must be dry and straight.
The brackets are sized for dressed 4x4 lumber, which measures 3.5 x 3.5 in.
The roof slopes at 15°, high at the front and low at the back, so the back posts are shorter than the front posts. The frame drops about 3.2 in. for every foot of level depth from front to back.
Back post length = front post length minus (level depth in ft x 3.2 in.). Example: 10 ft (120 in.) front posts and a 10 ft depth give back posts of about 88 in. (7 ft 4 in.).
Span is measured between two adjacent brackets: 12 ft is recommended and 14 ft is the maximum. Posts are recommended at 8 ft, with a maximum of 10 ft.
If you plan to add a roof, shade panels or another added load, confirm your design with your local building department.

Step-by-step instructions

Step 1: Build the top frame
- Lay the four 15° corner brackets out at their corners. Each bracket fits one corner only: check that the sloped beams will run downhill from the front to the back.
- Build a “U”: insert one level beam and the two sloped beams into the brackets.
- Build an “I”: insert the second level beam into the remaining brackets.
- Secure each bracket to the lumber with the provided screws.
Tip: Place cardboard under the brackets so they don't scratch your surface or the brackets.
Step 2: Insert the posts on the first side
- Lift one side of the frame and insert two posts into the brackets on that side, with a post base on the bottom of each post.
- Use the taller posts at the front corners and the shorter posts at the back corners.
- Secure each bracket to the lumber with the provided screws.
Tip: Have a helper hold the frame while you lift it and insert the posts.
Step 3: Complete the frame
- Insert the last two posts, with their post bases, into side 2 and stand the pergola upright.
- Check that the posts are plumb and the frame is square.
- Secure each bracket to the lumber with the provided screws.
- Anchor to your surface.
