Fence Post Spacing

For the approximate post spacing and associated number of panel blocksfor a concrete fence, refer to the table below. To accomodate a projects specific lengths, use a combination of two or three different post spacings in the block fence. Using the shorter post spacing may not reduce the pile depth.



Post Spacing Options
Number of Panel Block Post Spacing Increments*
4 7.2 ft (2.2 m)
4.5 7.9 ft (2.4 m)
5 8.6 ft (2.6 m)
5.5 9.4 ft (2.9 m)
6 10.1 ft (3.1 m)
6.5 10.8 ft (3.3 m)
7 11.6 ft (3.5 m)
7.5 12.3 ft (3.8 m)
8 13.1 ft (4.0 m)
8.5 13.8 ft (4.2 m)
9 14.5 ft (4.4 m)
9.5 15.3 ft (4.7 m)
10 16.0 ft (4.9 m)
10.5 16.7 ft (5.1 m)
11 17.5 ft (5.3 m)
11.5 18.2 ft (5.6 m)
12 18.9 ft (5.8 m)
*Each AB Fence Panel Block is approximately 1.5 ft (0.46 m) long. To get an approximate center-to-center post spacing multiply the number of panel blocks by 1.5 ft (0.46 m) and add 1 ft (0.3) to account for post blocks. This is used to obtain an estimated length and not for fence construction.
