Coverage planning tool
Estimate coverage before choosing products.
Review floor, gross wall, opening deductions, net wall, roof and waste separately. This is deliberately not a structural takeoff or purchase-ready bill of materials.
Start from a project study
Nominal floor dimensions only. Material height, opening deductions, roof factor, waste and rates remain unknown. Choosing a study here only previews its identity. The tool below continues to use your current private project until you explicitly replace it.

Nominal footprint: 120 sq ft. Coverage inputs and waste are saved separately for each candidate; unit rates are shared. Editing here updates Budget and your brief. Blank means unknown, not zero.

The simplified model uses the nominal footprint. Material wall height is a separate estimate, not your usable interior height; no gable, trim or product system is inferred. Verify actual surface dimensions with your provider.
