What to do with the number
The result is a sheet-count estimate, not a panel layout. Actual seams and stud placement may create additional offcuts. For tall walls or alternate sheet sizes, change the sheet coverage to match the panels you plan to buy.
Planning estimate
Use this result as a starting point, not a guarantee. Product specifications, site conditions, manufacturer guidance, local codes, taxes, labor, tolerances, and rounding can change the real requirement or cost.
