Estimate a room
Drag it to the size of yours. The walls show the board laid out the way we would actually hang it — four-foot courses, staggered, butting into the corners — so the sheet count is something you can check rather than something you have to trust.
Your browser can't draw the room, but the estimate below still works.
A house is taken off the floor area, not room by room. The model beside this is one representative room at your ceiling height.

Estimate
—
This is an estimate, not a quote. It is arithmetic on the sizes you gave us. Anything behind the wall — bad framing, old plaster, water — changes it, and we won't know until we look. The sheet count is real though: count them on the walls.
The finish level, more than anything else. Level 4 is paint-ready: the joints are taped and coated, the field is bare board. Level 5 skims the entire surface, so there is no difference in porosity between a joint and the board next to it. That is not a luxury — it is the only way a wall survives raking light from a big window or a run of pot lights set close to it.
Ceiling height. Past nine feet you are off a stepladder; past ten you are on stilts or staging. That changes the labour rate, not just the quantity, so it is applied as a multiplier rather than as more square feet.
Ceilings are slower than walls. Overhead work, a board lifter, more fasteners. Priced at a factor on top, not blended in.
Openings. A window is not a saving. It is four finished corners and a run of bead, and if the drawings call for a drywall return instead of casing, it is a great deal more than that.
Whether the framing is flat enough to take a reveal. Whether there is old plaster behind the board. Whether the ceiling is out by half an inch corner to corner. Those decide the real number and none of them are visible from a floor plan, which is why this ends in a conversation and not a checkout.
