## Is 2 2×6 or 1 4×6 stronger?

A 4×6 joist is theoretically stronger than a doubled 2×6 joist because it’s 1/2″ thicker, but the actual strength depends upon the knots and other inherent weaknesses of any particular piece of lumber (#2 lumber can have some nasty spike knots or large not-so-tight round knots or wane).

## Should I use 2×6 or 1×6 for decking?

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.

## How much weight can a floor joist hold?

A uniform load rating on a beam can easily be translated into what an equivalent maximum point load can be. For example, a floor joist at 16” spacing’s that can carry 53 pounds per linear foot would translate into a 318 pound single point load at its center.

## What size wood do you use for floor joists?

Looking at this table you will see there is a choice in the size of floor joist (2 X 6, 2 X 8, 2 X 10 or 2 X 12) and there is a choice in the joist spacing (12″, 16″ or 14″). The floor joist spacing is the distance between the centers of any two installed joists.

## How do you reinforce 2×6 floor joists?

If the floor is bouncy but the joists are not sagging, the simplest fix is to reinforce the joists by installing additional joists adjacent to the original ones.
