Also, how far can a 2x6 Rafter span without support? The table states that 2 X 6 rafters spaced 16 inches on center (o.c) can span a maximum distance of 13 feet 5 inches. Another option are 2 X 8 rafters spaced 24 inches o.c.

Then, how much weight can a 2x8 hold?

some of it gets pretty technical in nature, and mostly relates to pounds / square foot of loading. 2x6s are generally used for ceiling joists, esp since you said 24" oc and reallllly short spans only (5 or 6 feet ). Most floor loads would be a minimum of 2x8 @ 16" oc and most preferbaly 2x10.

How much weight can a 2x6 hold vertically?
