How to Use the Wallpaper Cost Calculator

  1. Enter the length and width of your room in meters.
  2. Enter the height of the walls in meters.
  3. Enter the price per roll of wallpaper.
  4. Enter the coverage area per roll (in square meters).
  5. Click the "Calculate" button to get the total cost of wallpapering your room.

Understanding the Formula

The calculator uses the following formula to determine the total cost:

Total Cost = (Room Length × Room Width × Wall Height × Number of Walls) / Coverage per Roll × Price per Roll

This formula calculates the total area to be wallpapered and then determines the number of rolls needed based on the coverage per roll. Finally, it multiplies the number of rolls by the price per roll to get the total cost.

Example

For example, if you have a room that is 5 meters long, 4 meters wide, and 3 meters high, and you want to use wallpaper that costs $20 per roll and covers 10 square meters per roll, the total cost would be:

Total Cost = (5 × 4 × 3 × 4) / 10 × 20 = $240
