What size lumber can span 24 feet?
|Maximum Span (ft - in)|
|Nominal Size (inches)||Joist Spacing Center to Center (inches)||Lumber Grade|
|2 x 10||24||16' - 8"|
|2 x 12||12||25' - 7"|
|16||23' - 3"|
Moreover, what size lumber can span 20 feet?
Re: 20 foot clearspan beam size In that case, you need something like a 12-16" GLULAM or LVL to span the 20' and can use simple 2x8-10 dimensional lumber 16"OC as floor joists.
Likewise, how far can a 2x8 beam span without support? In general terms, joists spaced 16 inches on center can span 1.5 times in feet their depth in inches. A 2x8 up to 12 feet; 2x10 to 15 feet and 2x12 to 18 feet. The larger the deck, the larger the joists.
Also know, how far can a 2x10 span without support?
When supporting joists that span 12 feet with no overhang beyond the beam, a double ply beam can span in feet a value equal to its depth in inches. A double 2x12 beam can span 12 feet; a (2) 2x10 can span 10 feet and so on.
What is the maximum span for a 2x10 floor joist?
