Should I use deck boards or 2×6?
2×6 is thicker and is stronger, but is also more expensive. Spacing between deck boards provide a few critical functions. The primary function is to drain water from the deck. Gaps that are narrow (1/8”), can catch debris, specifically on top of the joists, and can be difficult to clean out.

What does s3s mean when buying a board?
It stands for “Surfaced Three Sides”, which, as used in Goosebay’s hardwood lumber descriptions, indicates that two faces have been planed, and one edge has been processed with a straight-line rip saw, rendering the edge straight and smooth. The other edge is left rough, as the board came from the sawmill.
What is the best size wood for decking?
Width: Six-inch wide boards are ideal in most cases. Four inch wide material takes longer to install, creates more gaps and requires a lot more fasteners—but you can use it. Eight inch wide boards, because of their greater width, have more of a tendency to crack and cup; avoid using them.
What size is a large deck?
A small deck intended to hold a round dining table should be at least 12 feet by 12 feet, while a large deck can be designed with much more space. The average deck size is between 300 and 400 square feet. Generally, a deck should be wider than it is deep, with the longer dimension running along the house.
How much does it cost to space deck boards?
The goal is to have about an 1/8-inch gap (the diameter of an 8d nail) between boards after the decking has dried to its equilibrium moisture content. If the decking is installed wet, as is often the case for pressure treated material, it is best to install the boards tight, letting gaps form as the wood dries.
