Calculate the size needed for a beam, girder, or header made from No. 2 pine or LVL. Covers any span and every load with pin point accuracy. Double check yourself with these span charts. Works with evenly distributed loads only.
This door header size calculator can help you determine the correct size of wood beam to use as a header for your door (or window – the same rules apply). In this calculator, you'll learn about: How to properly size door frame headers; How to use the door header size chart; and; How to use this door header size calculator.
In general, the header size for a 3 to 4 foot span ought to be 4″×4″ lumber, while the header size for a 5 to 6 foot span ought to be 4″×6″ lumber. Likewise, the header size for a 7 to 8 foot span ought to be 4″×8″ lumber while the header size for a 9 to 10 foot span ought to be 4″×10″ lumber.
SFPA provides size selection tables for various beam spans and loading combinations for Southern Pine dimension lumber and glulam.
We’ll use a single 2×8 header. Begin with the difference in span for a given header configuration between the building width on each side of the actual building width. At 20 ft., a single 2×8 can span 3 ft. 11 in. At 28 ft., it can span 3 ft. 5 in., so the header span difference is 6 in. over 8 ft.
American Forest & Paper Association’s Wood Structural Design Data, provides span recommendations for solid-sawn wood beams up to 32 feet, but the table runs a hefty 140 pages. The WSDD is an extremely useful book (WSDD costs $20.
