Arborvitae Spacing and Width at Top

I prefer the staggered double row approach mainly because Emerald Greens are relatively slow growers when it comes to evergreens. Emerald Greens actually maintain their max width up to 80% of their height I would say. So if you plant them close enough in 1 row you will eventually get full privacy up to 8 ft if they are 10 ft tall, full & healthy trees.

Are you saying you are going to purchase mature trees that are 8-10 ft size? If you find those at a local nursery check the width and make your decision accordingly.

I have a few and our neighborhood's common areas have several as well. I will take some photos and share tonight since we have different sizes and I can show you how much they've changed over 5 years. PM me tomorrow if I forget!

I was recommending patience because he said he didn't have room for green giants. A staggered double row of emeralds isn't going to be much narrower.
I am not disagreeing that 1 row of Emerald Greens and patience will get the OP full privacy at 8ft - in fact that's what I would do if it's my property, but it appears the OP wants the quickest solution.

Two rows of staggered Emerald Greens placed close enough will still be narrower than a row of Green Giants based on my experience, and of course much shorter at X years. Some of my Green Giants planted 5 years ago as 10 ft tall trees are currently 25 ft tall which is great but they're also 12 ft wide and starting to concern me as they're too close to the house :shock:

Here's an example at our neighborhood mail kiosk area with 2 rows of Emerald Greens. The trees are about 8-10ft tall and by eyeballing it I think they're 4 ft apart? If the rows are closer together one can still have 2 rows without them being overly wide but it all depends on the space available for the OP to work with!



Here's our Emerald Greens in September 2016 vs. August 2020 (4 years). They were 6-7 ft tall when planted but have grown well and thicker over the years, but not as wide as some other Emerald Greens I've seen. As you can see the tree with multiple leaders grows wider up top than the one with a single leader. Also the orientation of the tree may make it thicker in one direction vs. the other. Both of which will also affect privacy at 8 ft in the future. Here are the photos:
