FAQ

Can I use Room Layout area here?

Yes. Room Layout wall and ceiling area can feed this calculator directly instead of entering area manually.

Why is sheet size editable?

4x8, 4x10, and 4x12 sheets are all common. Changing the sheet size changes the coverage per sheet and the rounded purchase count.

Does the sheet count include waste?

Yes. The waste percentage is applied to total area before dividing by sheet coverage, then the result is rounded up to whole sheets.
