Many people get confused when determining how many wallpaper rolls for a room. It is important to accurately calculate your square footage, taking into account the pattern repeat and openings such as windows and doors.

A good rule of thumb is to plan on six wallpaper rolls per room. This allows for a small amount of waste and ensures that you have enough to complete your project without running out.

Measure Your Walls

Whether you are ordering custom wall murals or standard wallpaper, it’s important to measure your walls so you don’t overpay or underorder. Using a metal tape measure to obtain the length and width of each wall will give you the most accurate measurements possible.

The next step is to determine the square footage of your walls in feet. Then divide the total square footage of your room by the usable square footage per roll of wallpaper. This will tell you how many wallpaper rolls are needed to cover your walls.

It is important to not subtract the area of doors and windows when calculating your wall heights. Subtracting these areas can cause the pattern to run off unevenly and result in a seam. In addition, you should always order a few extra rolls of wallpaper to ensure that you have enough for any future touch ups or mistakes. Purchasing extra wallpaper is also useful for when you want to add more interest to your room with additional features like wainscoting or chair railing.

Determine Your Pattern Repeat

If your wallpaper has a pattern repeat (usually stated on the product specification) this must be factored in. It will affect how many strips are cut from each roll of wallpaper, and also what size the overall strip needs to be.

Multiply the combined width of your walls by the pattern repeat (if applicable). Then divide this by the height of each wall, including any recesses and doors. For example, a room with 8 foot ceilings and a 2 inch pattern repeat would require 20 ft of usable wallpaper.

Do not subtract areas for doors or windows – this will not be the same as the actual wall space and could result in an insufficient amount of wallpaper being ordered. It is a good idea to order a few extra rolls just in case of any mistakes or if there are any future repairs needed. Also, having extra rolls is always handy for re-papering an area with a different dye lot.

Estimate Your Usable Square Feet

A square foot is the unit of measurement for a surface area such as a wall, floor or piece of fabric. It is equal to one foot tall by one foot wide.

Calculating your usable square footage is the first step in estimating how many rolls of wallpaper you’ll need for your room. This calculation takes into account the size of your pattern repeat and the height of your walls. I recommend this website for more wallpaper singapore.

The next step is to add the lengths of your walls together and multiply by their height. Then subtract any openings such as doors, windows or chair railing.

Finally, take the number of feet per single roll (found on your wallpaper specifications) and divide it by the adjusted height from Step 2. This will give you the total amount of wallpaper needed for your room. You may want to bring this estimate into a retailer for double-checking before you order your wallpaper. They can often assist with finding the best estimate for your project.

Order Extra Rolls

Many online wallcovering retailers offer a wallpaper calculator that calculates the number of rolls needed to cover a room. Unfortunately, these tools aren’t always accurate and don’t take into account specific pattern repeats or complex wall shapes. For this reason, we recommend using a tried-and-true method for estimating the number of wallpaper rolls required.

Start by finding the surface area of all walls in square feet. Next, find the height of all walls in inches. Divide the total length of all walls by the width of a wallpaper roll (provided in the product specifications). The result is the number of rolls needed for your project.

Don’t forget to add a few extra rolls for any mistakes during the installation process or any unforeseen hiccups. Also, remember that it’s a good idea to purchase all your wallpaper at once to ensure color consistency. This will also help to minimize wallpaper waste. For best results, use a metal tape measure and take measurements several times to get the most accurate numbers possible.
