How big of a beam do I need to span 18 feet?
What size lvl beam for a 18 foot span:- as per general thumb rule, for a 18 foot span, size of LVL beam or GLULAM should be 9 to 10 inches deep and 3 inches wide, thus you need something like a 9-10″ GLULAM or LVL to span upto 18 feet and can use simple 2×12 dimensional lumber at 16″ apart from centre as floor joists …
Also What size beam do I need for a 24 foot span? LVL beam size for a 24 foot span:- as per general thumb rule, for a 24 foot span, size of LVL beam or GLULAM should be 12-14 inches deep and 4 inches wide, thus you need something like a 12-14″ GLULAM or LVL to span upto 24 feet used for residential building or projects.
How thick should support beams be?
Measure the depth of your beam and then add an extra half inch. For example, if the beam is 7 inches deep, the support ledger should be set down 7 1/2 inches on the kind studs. This will give room to move the beam into place.

What size beam do I need to span 16 feet?
To span 16′ with joists 16″ apart, you likely need greater than a 2X12 joist lumber. IMO the project needs redesign with a beam to cut the span into shorter parts. Otherwise, consult a structural engineer to determine the possibility to use sistered joists, 4X lumber, or engineered lumber joists.
What is stronger 4×6 or 2 2X6? In general, the bending strength of a beam is directly proportional to its width and directly proportional to the square of its height. In the bottom case the 4×6 is theoretically 2² = 4 times as strong as a single 2×6, but since there are two of them it is only twice as strong as two2x6s.
How far can a 2×6 beam span without support? A 2×6 can support up to 50 pounds per square foot of weight without sagging with a maximum span of about 12 feet when spanning a distance horizontally, with the 2×6 standing in a vertical position. This number includes both live and dead weight.
How far can a 2×6 beam span?
