Depending on the load and the area where you live, a standard doubled 2"X10" header is good for about a 12' span. You can increase the span and load by using an engineered lumber product like a Micro-Lam. Your local lumber yard (Not Home Depot, or Lowe's) should have access to the information you need. Even with 4-2"x10"'s your only going to get about 12' of span max.

If I was building a 12 foot header I would nail two together and make it a 4 x 10. All my headers I substituted iron headers.

You have to use the snow load - which is 40 lb - looks like 6' tops.
