11 ' span- how much header?

Hubby is an experienced DIYer, but cautious. He is doing an 11' by 4' bumpout on our kitchen exterior wall. Can that distance be safely spanned??? How much header - two 2x8s, two 2x10s, or do we need a steel beam? HELP

for an 11' span a header will not suffice, he will have to switch to a beam, it can be 3 play 2x12, 2ply paralam, or a solid glulam. but it depends on the region depends on any point loads being transferred down from above. i would consult an engineer first before tackling this project

Ditto that

Thanks guys! You have given us the place to start. We will consult an engineer before we begin tearing out walls. M.R.
