As the title suggests I decided to install a pressure treated batten board fence. I was wondering how much gapping should I do. I am using 1x6 which are 3/4 x 5 1/2 actual. I have the posts set up with 8 feet spacing and was gonna do 1 1/2 inch overlap on each picket for a total of 24 pickets every 8 feet. I was wondering if this is enough overlap our to much?
