So, two 2x10s spanning 17 will support about 120 plf, which indicates your support beams are grossly oversized. Connection of the 2x10s to the 6x6s can be with 3 - 16d, which will support about 100 lbs. each nail. Of major concern is how the 6x6s will be supported and stay plumb.
This step by step woodworking project is about two post pergola plans. This is a nice project that anyone can add to their backyard, especially that Ive got you covered with step by step instructions and diagrams. This 2 legged pergola is ideal if you want to cover your bbq area or create a nice shaded area for your garden bench or hammock.
The last pergola I built I used 6 by 6 eastern red cedar posts. When I built a roof over my deck I had eastern red cedar posts cut that measure 4 1/2 by 4 1/2. These look great and were just the right size. Not too big, not too small. Of course you need a local source. If you have that source, you can get all of your materials of eastern cedar.
To dig the post holes, you can use a clamshell digger, power auger or a shovel. The depth of your hole should be about 1/4 of the height of your post. As a rule the width of your post hole should never be less than 10 inches. You want holes deep and wide enough to easily support a standard 4x4 post.
I am looking to extend my 4x4 corner posts on a deck to build a Pergola over top of the deck. I also plan on sleeving those 4x4's with a composite sleeve for the full length from the 4x4. So the extensions need to be flush, so plates and other things protuding cannot be sticking out of the sides.
Post sleeves cover the structural post used to support the pergola top. They can be 4x4, 5<5, 6x6 or 8x8 sleeves. Aluminum post stiffeners can be cemented into the ground or you can use wood 4x4, or 8x8 posts for support. Wood posts not provided by JAM Systems Beams are usually or Install the double box beam to the posts by drilling 1" holes in
Cut the ends of the support beams as shown above. Here are more designs you can use for the ends. Install the support beams to the 4×4 post using 3 outdoor screws. Use clamps to position and hold them in place. The support beams will stick out 12 on both ends. The support beams will be 3 below the top of the 4×4 post.
For most decks, post size is overlooked unless an inspector notices the unusual height of a particular deck. A short 4x4 can carry an awfully big load, and many deck builders use 6x6 posts as a standard, regardless of the height or load of the deck.
The pergola may someday support vines. I've found some online span charts, but they don't really apply to pergolas, which carry so much less load than floor/ceiling framing. Any help on the beam

To make your outdoor pergola perfect for your space, youll need to decide wood type, pergola dimensions, design style, attached to a wall or freestanding, and post information. Pergola post information includes the size and installation of the posts that are the legs for your pergola.

The footings for your deck or pergola will serve as the cornerstones of your support structure. Improper footings will make for an unstable frame, which can cause the wood to bow and warp and potentially cause harm to someone using it at the wrong time.
Why not just built it right once? The cost to build a pergola is normally in the 60 /40 range with 60 being the material cost. It would be possible to build one free standing but this would complicate the build as the support posts would need to be stabilized until the entire structure could stand on its own.
