How far apart can deck railing posts be?
6 feet
Spacing of Deck Posts The two most common sizes used for deck posts are 4×4 and 6×6. When using 4×4 posts, place them no more than 6 feet apart, and when using 6×6 posts, no more than 8 feet apart. The reason for these standards is that the railing system won’t have proper support if the posts are too far apart.
