Wallpaper can transform any room, adding personality, color, and texture to your space. But before you dive into the world of patterns and designs, it's crucial to know how much wallpaper you'll need. This is where the Amara Wallpaper Calculator comes in handy. It's a simple yet effective tool designed to help you accurately estimate the amount of wallpaper required for any room, saving you both time and money.

## Purpose and Functionality

The Amara Wallpaper Calculator is crafted to simplify the wallpaper planning process. By taking into account the dimensions of the room and the size of the wallpaper rolls, the calculator provides an accurate estimate of how many rolls you'll need to purchase. This tool is incredibly useful for both DIY enthusiasts and professional decorators alike, ensuring that you buy just the right amount of wallpaper for your project.

## Inputs Required and Calculations

To use the Amara Wallpaper Calculator, you'll need to gather some basic measurements of your room and know the dimensions of the wallpaper rolls you intend to use. Here are the essential inputs:

**Wall Width (W)**: The combined width of all the walls to be covered.**Wall Height (H)**: The height from floor to ceiling.**Number of Doors (D)**: To exclude the area covered by doors.**Number of Windows (Wi)**: To exclude the area covered by windows.**Roll Length (R_L)**: The length of each wallpaper roll.**Roll Width (R_W)**: The width of the wallpaper roll.

Based on these inputs, the calculator uses the following formulas:

**Total Wall Area (TWA)**:`TWA = W * H`

**Total Area of Doors and Windows (ADW)**:`ADW = (D * A_d) + (Wi * A_w)`

**Net Wall Area (NWA)**:`NWA = TWA - ADW`

**Area Covered by a Single Roll (A_R)**:`A_R = R_L * R_W`

**Number of Rolls Needed (N_R)**:`N_R = NWA / A_R`

, rounded up to the nearest whole number.

## Step-by-Step Example

Let's calculate how many rolls you'd need for a room with the following measurements:

- Wall Width (W): 10 meters
- Wall Height (H): 2.5 meters
- Number of Doors (D): 1
- Number of Windows (Wi): 2
- Roll Length (R_L): 10 meters
- Roll Width (R_W): 0.53 meters

Using the formulas:

**TWA**= 10 * 2.5 = 25 square meters**ADW**= (1 * 2) + (2 * 1.5) = 5 square meters**NWA**= 25 - 5 = 20 square meters**A_R**= 10 * 0.53 = 5.3 square meters**N_R**= 20 / 5.3 ≈ 3.77, rounded up to 4 rolls

## Relevant Information Table

Wall Height (H) | 2.5 meters |

Number of Doors (D) | 1 |

Number of Windows (Wi) | 2 |

Roll Length (R_L) | 10 meters |

Roll Width (R_W) | 0.53 meters |
