Proper size support beam.

I want to remove a 3ft. wall that is between two entrance openings.Openings measure approx.30 in. The ceiling is cathedral with no attic space above. Removing the wall will allow for wheelchair access. Will a 4x12 x14 work for this and carry load when wall is removed?

Two thrirty inch openings and a three foot space between them adds up to eight feet plus the bearing surface. It sounds like you need a ten foot beam. What load does it carry? A four ply 2x12 sounds over kill but I don't have enough information and if there is a substantial load, bearing points and a engineer will be critical.

I am confused. You say the wall is 3 feet, and there are two openings, each of which is 30 inches (2.5 feet). That makes a total opening of 8 feet, yet you propose to use a 4x12x14, which is fourteen feet long unless there is a typo in your post. So why would you use a fourteen foot long beam to span an 8 foot opening? Perhaps a drawing or a photo would help.
