How far apart can newel posts be?
Therefore, if you have a sixteen-foot balcony, you will need three newel posts, one at the beginning, one in the middle, and one at the end.

Unfortunately, a 4×4 post may not be able to withstand the weight, causing the entire porch to buckle. A 6×6 post gives you a little more long-term stability, particularly in those colder climates. Not only does it perform better when carrying heavier loads, but it also makes the heading for your roof more secure.

Why are newel posts so expensive?
The final feature that causes differences in price are the materials which box newel posts are made from. These may be large pieces of solid wood reducing the number of joints; smaller pieces assembled to make the sides, and finally veneered plywood, or other manufactured wood such as MDF or particle board.
How far apart are porch spindles?
Balusters are the vertical guards that support the handrail. They must be installed close enough that the space between them is less than 4 inches. Most city inspectors carry a 4-inch ball with them to test the spacing. Installed balusters should withstand 50 pounds of pressure exerted over a 1-sq.

About 90% of deck collapses occurred as a result of the separation of the deck ledger board from the house, allowing the deck to swing away from the house. It is very rare for deck floor joists to break mid-span. Many more injuries are the result of rail failure, rather than complete deck collapse.

The larger the deck, the larger the joists. 2×6 joists should only be used on ground-level decks that do not require, and will not provide for, any guards.
