LVL header size for 6' wide sliding patio door with small window above it

The walls are 9' high (2 * 6 construction) and the header will be supporting a cathedral ceiling with a 5/12 pitch. The wall will be a total of 18' long. The wall will only have a single top plate (issues with space). I'm wondering what would be the minimum size lvl that I should use to span the 6' space above the door? Can I go with less than a 2 * 10 lvl (rip if need be)?

Thanks

A double 9 1/2" LVL will suffice. Headers can't be single boards, and although the 9 1/2" is overkill you should not rip an LVL beam. If you are only spanning 6' plus jack/kings, you could use dimension lumber, say 2x8 or 2x6 doubled and sandwiched with plywood.

Edit: oops, I see 2x6 walls. It will need to be a triple 2x6 with a 1/2" plywood sandwich to fill out the space for sheetrock and exterior coverings. (1 1/2 x 3 + 1/2=5 1/2")
