How this works

Walls – Horizontal wrap / bands: Assumes the 10 ft width is used as the wall height coverage. This is usually the most efficient option for rooms with walls up to 10 ft tall.

Walls – Vertical drops / panels: Assumes sheets are hung as separate vertical panels, using overlap between each panel.

Ceiling / Floor: The calculator automatically chooses the strip direction that uses less material.

Overlap: Extra material added anywhere two sheets meet.

Important: This is an estimate. Real-world installation may require extra material for trimming, folding around corners, taping, doorways, windows, or awkward layouts.
