Your wall is 12 x12 ft =144 sqft. One standard non adhesive wallpaper roll comes in size of 57 sqft per roll. You Will need 3 wallpaper rolls. please check wallpaper length before buying as wallpaper comes in many sizes.
Depending on the wallpaper sheet width, a double roll covers 57 to 61 square feet, while a single roll is 29 to 31 square feet. Remember, wallpaper only comes in double rolls, even though they price out the cost in single roll quantities. You can count on double rolls to always be twice as long as single rolls.
Divide the total square feet of wall space by 27 to determine the number of rolls required. The formula is: Square footage ÷ by 27 = Number of rolls. At this point, you could subtract 21 square feet for any doors and 15 square feet for each window.
A standard roll of wallpaper gives you about 35 square feet, but waste and pattern matching usually take this down to about 27 usable square feet per roll.
The most accurate way to calculate wallpaper quantities is by figuring out how many floor-to-ceiling strips you'll need in the room, and then determining the number of usable strips on each roll of wallpaper you plan to purchase.
The simple answer is three. For an average-sized room, you will get three drops of wallpaper per roll with some paper left over for finishing around windows and doors. For rooms with lower ceilings, you may get four drops per roll and for those with extra high ceilings, you may only just get three drops.
Lower cost: Paint is cheaper to buy and put up than wallpaper. If you're doing the job yourself, you can save even more. Easy to change: If you decide you don't like a color or want to stay current with paint color trends, it's easy to change. Just paint over with a primer and a couple coats.
Cost of installation will be a bit more once hanging supplies such as sponges, rollers, brushes, paste (if needed), and blades are figured in. A 10x10 square foot room should require about 6 rolls. So on average, for a room about that size, you can expect to pay $90 to $100 plus the cost of supplies.
In the U.S.A., a single roll of wallpaper is typically defined as a wallpaper roll with the dimensions 21 inches wide and 16.5 feet in length (21″ x 16.5′).
How to find square feet: multiply the length measurement in feet by the width measurement (in feet). This yields a product called the area, which is expressed in square feet (or square inches if you are calculating a much smaller space, such as a dollhouse).
A single wallpaper roll and double wallpaper roll are both just one roll of wallpaper, with a double roll being a longer length than a single roll. In other words, two single rolls = one double roll. The standard double roll wallpaper size is 20.8” wide x 33' long.
Clean the wall surface to remove any dirt and debris. Install the wall covering, overlapping each panel. Each panel includes an overlap (typically 1″) on the left and right edge. Using a straight edge to guide the razor blade, make a cut down the center of the overlap.
For up to 3 rolls of wallpaper, we would advise 2.5kg of paste. For larger projects of up to 6 rolls, 5kg of wallpaper paste.
Take the height measurement of the room/area in metres and multiply it by the number of widths needed. Divide that number by the length of the wallpaper roll – usually 10m – and you'll have the number of rolls needed.
Vertical stripes, ones that go up and down, will help to stretch a room and make it feel taller than it is. Fun fact, that's one of the tricks behind Walt Disney World's Haunted Mansion pre-show. Striped wallpaper that runs horizontally, on the other hand, can make a room appear wider than it really is.
New walls must be thoroughly cured, dry and primed. For previously painted walls fill cracks or holes with patching paste, then sand smooth. Spot-prime the patches and prime all walls to be papered.
Maintenance: Requires careful cleaning, making maintenance a bit challenging. Cost: Typically more expensive due to its luxurious finish and intricate manufacturing process. Suitability: Not ideal for high-traffic or damp areas due to its delicate texture.
It depends on a few factors, like the layout of the room, how much preparation the walls need and the size of the walls. Typically, wallpapering a room takes about 6 to 8 hours, but this can extend to a few days if the wall needs significant preparation or if old wallpaper needs removing.
Durability and Longevity
Wallpapers, especially peel and stick vinyl options, are known for their durability. Unlike paint, which may chip or require touch-ups, wallpaper can maintain its appearance for years, making it a cost-effective long-term investment.
Our standard wallpapers come in rolls of approximately 10.05 m or 33 ft (11 yd) long and 0.53 m or 1 ft 10" (21 inches) wide.
Allow a full day for removing paper from an average-size room. If you're removing strippable wallpaper and the paper surface of your drywall comes up with it, stop immediately. When this happens, it generally means that the drywall wasn't sealed with enough paint.
Taking a quick measurement of your wall length and ceiling height will confirm how many drops you can expect from your roll of wallpaper. Typically, ceiling height is around 2760mm. If this is the case, you will get three drops from a standard 10m length & 53.5cm width of wallpaper.
