What is the actual thickness of a 5 4 board?
5/4ths is a common pre-cut of lumber, but the actual thickness of the board is 1.25 inches .
What are the dimensions of a 5 4 deck board?

What is the standard size for deck boards?

How far can a 5 4 deck board overhang?
The edge of decking should never overhang more than one-third of the decking material . For your standard 5.5” decking, that is 1 3⁄4” overhang.
Why is it called 5 4?

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.
Is it better to use 2×6 or 5 4 decking?
For those looking for a distinct wood decking look, 5/4 decking is a good choice at an economical price. For those looking for a more robust, bulkier looking decking, 2×6 decking is a good pick with a square profile.

How many square feet does a 16 foot deck board cover?
EXAMPLE: Say you've chosen the 16-foot standard width deck board. First, take the width (5.5 inches) and convert it into feet by dividing it by 12 inches, which gives you 0.45 feet. Then multiply 0.45 by 16 to get the board's area: 7.33 square feet .
What size boards are best 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.

Do you need space between deck boards?

So the question is, “How much can we cantilever the far ends of the joists?” Looking at the table below, we see that 2×6 floor joists can be cantilevered up to 2 feet and 6 inches (2′-6′′) when the joists are spaced 16′′ apart.
Why are 2x4s not actually 2×4?
DIMENSIONAL LUMBER:
In the past, when a timber was called a 2×4 [or “two-by-four”], it actually measured 2 inches by 4 inches. ... Because of this extra milling, a 2×4 no longer measures a full 2 inches by four inches . Instead, a 2×4 is really only 1 1/2′′ by 3 1/2′′.
What does the time signature 5 4 mean?
