Instead of building a free-standing, 4-poster Pergola, I attached one side directly to the house. There are various Pergola design types and shapes. Simply Google for "pergola" images and decide which design you like best, or combine design ideas together (as I did).
Couple things to consider:
A: Is your Pergola more for decorative purposes or actual shade?
My design was more for actual shade (but with a decorative design), which is why I added the 1in x 12in x 12ft Pine boards between the cross beams at the very end (last picture). If your design is more for decorative purposes, you can space out your support beams and cross beams wider (using less wood and money).
You can also choose to use 2x4s as your support beams with 2x2 cross beams on top (essentially furring strips) either close together or spaced farther apart. This would also reduce the overall cost of your Pergola and make it much lighter as well. I chose to use all 2x6s for both support beams and cross beams.
B: What path does the sun follow across the sky over your Pergola?
If the sun passes directly over your Pergola and you want a lot of shade, you'll obviously need to consider this in your design (i.e., more cross beams that are close together).
C: Do you want your support beams and cross beams to inter-lock (by cutting square notches and assembling them like linking logs), or simply stacked on top of each other? (Again, Googling for Pergola images will help you see the differences in designs.)
I chose to interlock all of my beams by cutting notches and fitting them together. Obviously more time consuming to measure each notch, cut, and chisel them but the stability of inter-locking beams should hold up a little better in the strong winds of Las Vegas.
HOW TO (abbreviated)
Overall Pergola Dimensions: 10ft Height, 12x12ft
Tip: Paint or stain all your wood prior to assembly. Much easier. You can always touch-up scuffs and scrapes after it's built.
1. 2x6x12 installed directly onto the house (thru the stucco into the studs) using 3/8in. x 5in. lag screws. (Tip: Seal the top edge of the 2x6x12 that's against the stucco so water doesn't run behind it and down into the lag screw holes.)
2. Install the 2x6 Double Shear Hangers (as many as you need for your design)
3. 4x4 post anchors secured directly into the cement patio using Tapcon 3/16 in. x 2-3/4 in.cement anchor screws.
4. 4x4x10ft posts screwed on top of the anchors. Ensure level on all sides (use a partner to help hold the posts).
5. Attach the front and side 2x6 beams to the 2 posts (again, use a partner to help hold posts while you're up on the ladder screwing your beams to the posts)
6. Attach the remaining 2x6 support beams.
7. Attach the 2x6 cross beams on top (whether you inter-lock them by cutting notches or simply resting them on top, be sure to toe-nail screw them in with 2in exterior screws).
8. Lay 1x12x12ft pine boards on top in between the cross beams and secure with 2in exterior wood screws.
9. Construct the post bases ("sleeves" or "leggings") which greatly adds to the look, as outlined in the "Weatherly Pergola" plans.
10. Touch-up paint / stain any areas you need.

My loveseat version of Ana’s Plan
You can make the 1x10 in any length you want. I’m planning on making a loveseat too and The measurements I chose for the seating area will be 48” long (which is the size for 2 seat cushions).
The Step 1 in Ana’s plan, all measurements will be the same.
Step 2: The two 2x4 horizontal supports will be cut at 48”.
Step 3: the two 1x10 seat panels will be 3 inches longer than the horizontal supports. So you will cut the 1x10 seat panels at 51”.
Step 4: Instead of two, you will need THREE seat supports. So cut three 2x4’s @ 32 3/4”. The third seat support will go in the middle of the other seat supports, drilled to the horizontal back support.
Step 5: Attach your back bottom horizontal support which will be a 2x4 at 48”.
Step 6: Attach the 1x10 seat back panels. You will cut (3) 1x10 @ 48”.
Here is the cut list for the loveseat version of Ana’s Adirondack plan. These are the lengths I chose. So with this cut list your loveseat should be big enough for two 24x24” seat cushions. I plan to add cushions for extra comfort.
My cut list:
(2) 2x4 @ 31 3/4”
(2) 2x4 @ 19 1/2”
(2) 2x4 @ 33 1/4” Cut at 20 degrees as per Ana’s plan.
(3) 2x4 @ 48” Horizontal supports. One goes behind your calves.
The other connects the end frames/arm rests at the back.
(2) 1x10 @ 51” Seat panels.
(3) 2x4 @ 32 3/4” Vertical supports for the back panels.
(3) 1x10 @ 48” The back panels.

P.S.
You will also need an extra support attached underneath the seat panels in the middle for extra support and keep the long seat panels from bowing.
