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.
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.
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.
This guide features Trus Joist® engineered lumber in the following widths and depths: TimberStrand® LSL. 1.55E TimberStrand® LSL header and beam sizes: Widths: 13⁄4" and 31⁄2" Depths: 91⁄2", 117⁄8", 14", and 16" Microllam® LVL.
Formulas that determine the allowable span and size of a beam rely on a host of variables like species, grade, size, deflection limit and type of load. You can do these calculations yourself or you can use span tables.
SFPA provides size selection tables for various beam spans and loading combinations for Southern Pine dimension lumber and glulam.
