Every room is different, and even if you had a standard sized living room it would still be important to measure for wallpaper. This will help to minimize waste and ensure you have enough material for your project.
Measure each wall with a tape measure and record the width. Then add the total together to get the perimeter of the room.
Use a Tape Measure
While wallpaper calculators exist online, it’s best to do your own measurements for a few reasons. First, a calculator will not account for ceiling height or wall width, which is important to take into consideration when ordering your wallpaper. Second, calculators usually rely on square footage, but this can leave you short, especially with patterned wallpapers that require careful overlapping.
The first step is to use a metal tape measure (not a cloth one) and get an accurate measurement of the length of each wall in your room, including obstacles like baseboards or crown molding. Write down these measurements, as you will need them later.
Now, move along each wall to measure the height from floor to ceiling, again excluding any obstacles, such as doors or windows. Then, divide the length of your room by the width of a single wallpaper roll, taking into account any pattern repeat. This will give you the number of usable, floor-to-ceiling strips that each roll should provide.
Measure the Width
Some wallpaper sellers offer online calculators that estimate how much wallcovering you need, but these tools are not always accurate. They typically take the room’s square footage into account but may not take into consideration specific pattern repeats or deductions for windows and doors. Using a hand calculation method is far more reliable, and will also give you better precision for your measurements. Get more info on this wallpaper singapore website.
Start by measuring the width of each wall, including any wainscoting or chair railing. Multiply that number by the height of your walls to get an estimate of how many full strips you will need from floor-to-ceiling.
Next, divide that number by the number of full drops (provided in the product specifications) per roll to see how many rolls you need total. It is generally a good idea to order 10% more than you need for touch ups and mistakes. This will ensure that you have enough on hand for your project.
Measure the Height
Using a metal tape measure and subtracting the areas of doors and windows (or other openings), find the height of each wall. Multiply this number by the width of the wallpaper to obtain a measurement in meters. The resulting figure will be the area of your walls in m2, which you can enter into our wallpaper calculator to help you determine how many rolls you need for your project.
Note: If you are using a pattern wallpaper, add the length of the pattern repeat to your height measurement to calculate an adjusted height. This is an important step to avoid potential waste as you line up your pattern.
Alternatively, you can hand calculate how much wallpaper you need for a room by using the following method. This will give you a good estimate, but we recommend that you purchase additional wallpaper for unforeseen hiccups or repairs. It’s also a good idea to order your entire job at once so that you can be sure the colors are dyed in the same batch.
Measure the Perimeter
Most wallpaper measurement guides recommend calculating square footage of the walls to determine how many rolls you’ll need for your room. However, Hogan argues that calculating the total area of your walls (excluding baseboards and crown molding) is a more accurate method.
This approach can help you avoid getting short on wallpaper or finding yourself with extra at the end of your project. It’s also better for estimating patterned wallpaper, which requires more material because of the way it repeats.
Be sure to subtract the areas of any doors or windows from your measurements. You’ll need to buy more wallpaper than you would for a solid wallcovering because of how much waste is involved in cutting around these features. Finally, add 10% to your calculations for waste and pattern matching. This will help you estimate how many rolls you’ll need for a successful job and save you stress if you’re running low on your final order.
