What changes these estimates most
Board size, framing layout, offcut waste, fixing patterns, and whether the job includes more corners, cut-outs, or awkward ceiling work all affect the total.
Where people under-order
It is common to estimate sheet count reasonably well but forget how much screws, compound, tape, and trim details add to the final buying list.
Before you order
Check board dimensions, framing centres, fixing rules, and whether tape, beads, jointing materials, or vapour-control layers need their own quantities.
