Similarly one may ask, how short can deck posts be?

Avoid Short Deck Posts But posts under 10 inches in length, with nails securing fasteners at the top and bottom, are prone to splitting. You can usually design your way around short posts by increasing the beam size or raising the height of the concrete piers.

Also Know, should I use 4x4 or 6x6 deck posts? A short 4x4 can carry an awfully big load, and many deck builders use 6x6 posts as a standard, regardless of the height or load of the deck. Though the height of a deck is often questioned only in regard to the requirement for guards, it is a factor in determining the height or “span” of the posts.

Subsequently, question is, what is the maximum height of a deck without railing?

30 inches

How do you install deck railing posts?

After the decking is finished, it will be time to install the top and bottom rails, balusters, top cap and any other parts.

1. Mark rail post centers.
2. Mark for the exact position.
3. Cut the post and tack a guide nail.
4. Plumb and clamp the post.
5. Drill holes for the bolts.
6. Pound the bolts through.
