An Arborvitae will spread about 4 feet at maturity - which would be two feet on either side of the center line. There are a good variety of photos here that you should look at after you see my recommendations below.

This spread is not achieved until the tree is several (3-5) years old. Like most plants the growth rate is faster when the trees are younger.

Accordingly, the farthest apart I would plant them is 48" center to center, with the understanding that it will take about 4 years for them to look like a hedge. A better spacing would be 36" center to center, which will create a lower, but still growing, hedge, in 2-3 years.

Hope these thoughts help.
