1. What is a Wallpaper Roll Calculator UK?

Definition: This calculator determines the number of wallpaper rolls required to cover a wall area based on standard UK roll sizes.

Purpose: It helps homeowners and decorators accurately estimate wallpaper quantities needed for a project, minimizing waste and extra trips to the store.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The total wall area is divided by the coverage per roll, and the result is always rounded up to ensure full coverage.
