Calculating the Necessary Amount of Wallpaper to Purchase

When it comes to embarking on a home improvement project, one important aspect that often requires careful consideration is the amount of wallpaper needed for the walls. Purchasing the right quantity of wallpaper is crucial to avoid running out in the middle of the job or ending up with excessive amounts of unused wallpaper. To ensure precise calculations, it is essential to follow a systematic approach. In this article, we will explore the steps involved in calculating the necessary amount of wallpaper to purchase.

Step 1: Measure the walls

The initial step in determining the required amount of wallpaper is to measure the walls accurately. Use a tape measure and start from one corner of the room, moving towards the adjacent corners in a clockwise or counterclockwise direction. Measure the height of each wall from the floor to the ceiling, making sure to include any spaces above windows or doors. Write down the measurements for each wall separately.

Step 2: Calculate the total square footage

Once the measurements have been recorded, the next step is to calculate the total square footage. To do this, multiply the height of each wall by the width. If you have specific sections of the wall that won’t be covered with wallpaper, subtract their square footage from the total. Continue this process for all the walls in the room, and add up the square footage to determine the total required.

Step 3: Consider pattern repeats and wastage

When selecting a wallpaper pattern, it is essential to consider the repeat length. The repeat length refers to the distance between the start of one pattern element to the start of the next occurrence of the same element. For example, if the repeat length is 12 inches, then every 12 inches, the pattern will repeat. Keep this in mind while making calculations to ensure a seamless pattern. Additionally, it is advisable to consider a wastage factor of approximately 10-15%, accounting for mistakes, trimming, and future repairs.

Step 4: Consult the wallpaper roll specifications

Wallpapers come in different roll sizes, typically ranging from 20.5 inches to 27 inches wide and 33 feet long. Consult the specifications of the chosen wallpaper to determine the coverage per roll. This information should be provided by the manufacturer. Divide the total square footage obtained in step 2 by the coverage per roll, and round it up to the nearest whole number. This will give you the minimum number of rolls required.

Step 5: Final adjustments

Lastly, evaluate if the number of rolls calculated covers any additional factors, such as doorways, windows, or any other features that may alter the required amount of wallpaper. Make the necessary adjustments by adding or subtracting rolls accordingly.

By following these step-by-step instructions, you will be able to accurately calculate the necessary amount of wallpaper to purchase for your home improvement project. Remember to double-check your calculations and consult with professionals or the store if you have any doubts. Investing time in precise measurements and calculations will ensure a successful and visually appealing result, saving you from the hassle of running out of wallpaper or ending up with excess rolls. Happy decorating!
