1. What is a Plasterboard Quantity Calculator?

Definition: This calculator determines the number of plasterboards required based on the total area to be covered and the area each board can cover.

Purpose: It helps construction professionals and DIYers estimate how many plasterboards are needed for drywall projects.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ N = \frac{A}{A_p} \]

Where:

Explanation: The total area is divided by the area one board can cover, then rounded up to the nearest whole number since you can't use a fraction of a board.

3. Importance of Plasterboard Calculation

Details: Accurate calculation helps prevent material shortages or wastage, ensures proper budgeting, and helps with project planning.

4. Using the Calculator

Tips: Enter the total area in square feet and the area per board (standard 4×8 board covers 32 ft²). All values must be > 0.

Q3: Should I add extra boards?
A: Yes, it's recommended to add 10% extra to account for cuts, waste, and mistakes.

Q4: How do I calculate the total area?
A: Measure wall/ceiling length and height, then multiply to get square footage. Subtract window/door areas.

Q5: Does this account for different board thicknesses?
A: No, this calculator only considers coverage area. Thickness affects other properties but not quantity needed.
