I would like to try to use the minimum size beam because of head space. Can I get away with a 4x8 for the 10ft span or use a 4x10"
So the ceiling joists are resting on a support beam and you want to take out that beam and put in a smaller one.
Why would there be a beam in a 10 ft wide room?
There's something odd about this structure.
Take some pictures of the ceiling and let us know what size ceiling joists you have and what's above this room.
