When it comes to columns, the size comes down entirely to the kind of floor area that it will wind up supporting. The beam is typically supported at each end on exterior walls and may have one or more support posts along its span. But overall, for short spans, sawn-lumber is tough to beat. And the garage door header is based on a 2-car garage-door opening. Any accurate calculation of beam size must take into account the tributary load area for a beam, based on its spacing and the magnitude of load being carried. For a floor beam, select the appropriate span table for one or two floors, identify the distance it needs to span, the depth and width of the beam, the span carried by the beam, and the live or total load. These calculators make it as easy as possible to determine the beam for a span. Live load determines stiffness and total load is used to determine strength. You will also need to ensure that the concrete flooring, 2-3 inches or so, is poured over top of the floor to add additional support.
