The Code Council has revisited how best to provide an online, professional Discussion Forum and area within the website that has a sense of community – where Members and nonmembers can provide input and exchange ideas with their peers in the industry. The new Codes & Standards Discussion Forum does just that, as it allows Registered Website Users and ICC Members to discuss the I-Codes in an online community.
Note to Nonmembers: If you join the ICC you can have access to important building safety information!
As an ICC Member, you have access to the Members Area of the Codes & Standards Discussion Forum. Follow the link to discuss the Membership Councils and other benefits of being an ICC Member.

Need some help with the Header span table!!!
No snow load in my area.
20'x20' attached garage with 16' garage door opening.
The proposed header for the garage door opening is 4X12, DF#2.
Per the table, what is the max span for a 4X12, DF#2?
A 4X12 is not within the persricptive numbers of the code
A 16 ft span is not within the tables either
Is it supporting the trusses or is it on a gable endHow much overhang and what is the pitch of the roof, live loads (wind) and dead loads of your area
ICC does not stand for Intentionally Clear and Concise

I'm thinking your LL is 20 psf construction live load but I don't think your DL is 113 psf and you haven't really answered Mnt's questions about what framing (what tributary area) loads the header in question.
But, unless you are a plan reviewer trying to check a submittal, this may not be the appropriate place. If you are out of the presciptive portion of the code, then you or someone needs to design the framing using accepted engineering practices. In my opinion, someone answering code questions on one of these forums isn't really that person.
