1. What is a Wallpaper Calculator for South Africa?

Definition: This calculator estimates the number of wallpaper rolls needed based on wall area and roll coverage specific to South African standards.

Purpose: It helps homeowners and decorators accurately purchase wallpaper without excess or shortage.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( R \) — Number of wallpaper rolls needed (rounded up)
• \( A \) — Total wall area (square meters)
• \( Roll\_A \) — Coverage area per roll (square meters)

Explanation: The total wall area is divided by the coverage per roll, then rounded up to the nearest whole number since you can't buy partial rolls.

3. Importance of Accurate Wallpaper Calculation

Details: Proper calculation prevents waste, ensures pattern matching consistency, and helps budget accurately for decorating projects.

4. Using the Calculator

Tips: Enter the total wall area in square meters and roll coverage (default 5.3 m² per roll, standard in SA). All values must be > 0.
