## How do you calculate header beam size?

It went like this: Measure the span in feet and add 2 to that number. The sum will be the height of your double header in inches. For example, if the span is 4 feet, add 2 to 4 for a sum of 6. Therefore, the header would need to be made from doubled 2x6s.

## How do you calculate load bearing beam size?

Multiply the loading per square foot by the area in square feet of the surface which the beams will be supporting. Divide by the number of beams which will be installed to get the loading per beam.
