Before beginning a wallpaper project it is important to know how much paper you will need. You can use an online wallpaper estimation calculator or bring your wall measurements to a local retailer. Remember to account for the surface area taken up by doors, windows and trim.

To find the total surface area of your walls, multiply the length (perimeter) of each wall by its height. This will help you estimate how many single or double rolls of wallpaper you need.


Wallpaper is an effective way to add color, pattern, and texture to your home. It can also make a room feel more welcoming and comfortable. But it’s important to accurately estimate how much wallpaper you need. This will help ensure that you don’t end up with too much or too little.

To calculate how many rolls of wallpaper you need for a room, begin by determining the total square footage of the walls. This can be done by adding the length of each wall and multiplying it by its height. Then, divide this number by the usable square footage per roll of wallpaper.

Most wallpaper patterns have different amounts of usable square footage per roll. To find this number, look at the wallpaper’s specifications or ask your retailer. Some patterns require a full drop, while others have a half or 1/4 drop. Then, subtract the number of doors and windows from this total to determine how many rolls you need.


Wallpaper is a fun way to add color, pattern and texture to your walls. It also allows you to create a custom space that suits your personality and style preferences. However, it’s important to accurately estimate how much wallpaper you need to avoid ordering too little or overpaying for the material.

The length of your room can be found by dividing the total perimeter by its height. Multiply the result by the coverage per roll and add 10% for waste factors. Typically, a single roll of wallpaper covers 27 square feet of wall surface area and a double roll covers 54 square feet.

You should also factor in the pattern repeat. A random match will have no repeat, but a regular pattern requires a certain amount of waste to ensure that the patterns line up correctly on the walls. This is because you’ll need to leave a certain amount of space between each row of wallpaper to account for the pattern and the vertical “drop” needed to align the next section with the previous one.


Wallpaper is a beautiful way to add color, texture, and pattern to your walls. It can also be used for cabinets and ceilings, but it is more expensive than painting. It can take longer to hang and remove, and there may be a fee to dispose of the old wallpaper. It is also not as durable as paint, and it can easily be damaged by moisture or other factors.

When estimating how much wallpaper you need, it is important to know the height of each wall. You should measure the height of all walls, including baseboards and crown molding, and multiply it by the length of each wall to determine the total area. You should also account for any windows or doors, which you will need to cut around as you hang the wallpaper. In addition, you should calculate the pattern repeat and add it to the overall surface area to find out how many strips of wallpaper you will need.

Surface Area

Wallpaper is an excellent way to add color, patterns and texture to your walls. But it is expensive and requires professional installation. If you are looking to save money on your project, it is important to accurately estimate how much wallpaper you will need. This will ensure you don’t order too little or too much, and will avoid any potential problems such as dye lot differences.

To calculate the total surface area of your walls, simply add up the lengths of all the walls and multiply by their height. Be sure to include any doors and windows in this calculation. Then, divide the total wall area by the amount of usable square footage per roll (or “TSF”) to find out how many single rolls of wallpaper you will need.

A standard roll of wallpaper covers about 35 square feet. However, you will need to factor in the pattern repeat and any openings. These factors will reduce the usable coverage per roll.
