another consideration might be the direction that the boards on your pergola run. the horizontal closure strips need to be installed on top of parallel boards that are less than 3 feet apart. so if the boards on top of your pergola run the wrong way, youll need to add some additional ones on top.
the key thing to remember when it comes to determining pergola rafter spacing is that you cannot go more than 16 inches from center-to-center between rafters. even though most pergolas dont have anything going on top of the rafters, most building codes require them to have the same spacing as structures that support floors or roofs.
its worth a few minutes of your time to investigate the sight lines from the house, the interior windows, and any other point from which the pergola will be visible. if you can see the top of the pergola from a second-floor window, for example, you may want to route wires or conduit for a ceiling fan so that theyre hidden.
tip: hopefully everything will align perfectly, but if you have to choose, line up the bottom sides of your rafter frame boards, as this is what will be visible. the top part of your pergola wont be all that noticeable, in general. use a scrap board and hammer to create a flat connection on the bottom ends of your boards, if necessary.
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
header boards your pergola will need a set of double-header boards that attach to each side of the post and are secured by 10 bolts. we use 2 x 8 or 2 x 10s for our header boards they add strength and a great look to the piece. you will need a total of 4 header boards for the pergola.
it's just four posts and some boards, but a pergola must stand plumb, level and square through all kinds of weather. i chose attractive, naturally rot-resistant western red cedar for this job.

the posts are 6x6 and the beams are paired 2x10. the joists on top of that are 2x8, and theres deck flooring on top of that. there is also a ledger that runs the width of the deck, so it is attached to the house. i dont want to attach the pergola to the house though. my idea for the pergola is this:
pergolas provide attractive shade options for your attached patio or other areas throughout your yard. many have open roofs, using wide rafters to cast shade for much of the day, although closed
each one, while built on the same principles, can look vastly different. take the rafter tailsthese are the decorative edges where the rafters cantilever outside the pergola's four-sided frame. they're a focal point, and spending a little time designing them is a good way to distinguish the entire structure.
the key to designing a pergola is its visual proportion. with 2×6 posts, the girders and cross-members will need to be larger, otherwise the top of the structure will look undersized and anemic. you also have to consider allowable span, based on the size of the pergola youre building. a 12-foot span is much too long for a 2×6 board, for example.

on an attached pergola, the ends of the rafters are attached to the ledger board at one end and sit on top of the beam at the other. with a freestanding pergola, the rafters typically sit on top of the beams on both sides. as with beams, it's common to cut the ends of rafters with decorative shapes.
before putting up a pergola, you need to have a tall fence or support posts with a top beam in order to mount the pergola beams. you can check out my post about building a slat wood privacy fence where i talk about mounting posts and creating the base which we used to support one side of the pergola.
the slanted slats on this pergola create more cool, relaxing shade for hot, summer afternoons. the wood of the pergola matches the wood around the exterior of the house as well as the wood used for the seating and tables. the grays used for the flooring, cushions, pillows, and tiles in the table top also echo each other. 3.
