Room 0.1–200 m per side (or feet equivalent), ceiling height to 20 m, doors ≈1.9 m² and windows ≈1.5 m² each, waste 0–50%. Estimate is for one side of each wall — double sheets when boarding both faces, and openings are whole-area subtraction only.

How to use

  1. Enter room length, width, and ceiling height.
  2. Count doors and windows, set waste.
  3. Read the sheet count for each size.

What it supports

One side of each wall only — double the count for both faces. Doors ≈1.9 m² and windows ≈1.5 m² each, removed as whole-area subtraction. The ceiling is optional and on by default. Room sides 0.1–200 m, height to 20 m, waste 0–50%.
