first you need to calculate the load on the entire floor. Different uses mean different loads, you look that up in the building code. Then you calculate how much of the floor is held up by the beam. Then you look up what size of beam to use for the number of pounds per lineal foot. For 1 or 2 family homes you can have a lumber yard do this for you. For commercial construction it has to be done by an architect or an engineer.
