When hanging wallpaper, it is essential to have enough to cover your walls. This will prevent you from running out mid-project or spending more than you need to.
To figure out how much wallpaper you need, start by finding the total square footage of the surfaces to be covered. Then, determine the usable coverage per roll and add 10% for waste.
Measure Your Walls
Wallpaper is a great way to add a pop of color and interest to your home. It is also more durable than paint and can be hung easily by a professional. However, it is more expensive and requires a bit of planning to determine how much material you will need.
Use a tape measure to find the lengths of all walls in the room that you plan to wallpaper. Then add those lengths together and multiply them by the height of the wall to find the total surface area. Remember to include openings like doors, windows and ventilation. For more info I’ll suggest you visit the website wallpaper singapore.
When calculating how much wallpaper you need, keep in mind that each single roll of wallpaper provides about 27 square feet of usable coverage. So if you are using double rolls, you will need about 54 square feet to cover the walls in your room. Always account for 10% waste factors to ensure that you will have enough wallpaper to complete your project.
Calculate the Surface Area
Most wallcoverings are patterned and require more material than solid wallpaper. This extra material is a result of the pattern repeat, which is the vertical distance between identical sections of the design or motif. The pattern repeat should be indicated on the wallpaper packaging or listed under the product specifications if you purchase it online.
Start by measuring the width of all the walls and adding them together (Combined Width). Next, measure the height of all the walls and add them together (Combined Height). You’ll then need to multiply the Combined Width and Combined Height to find out how much square footage your walls have.
Divide this number by the usable coverage per bolt of wallpaper to find out how many single or double rolls you need to cover your walls (including 10% waste factors). Don’t subtract surface area for doors or windows since you can simply cut the wallpaper as you go and these areas will not be visible once the room is finished.
Determine the Pattern Repeat
When measuring a room for wallpaper it’s important to take the pattern match into consideration. This is the number of times the same part of the design repeats itself along the length of a single roll of wallpaper. This value can be found on the wallpaper’s packaging or in its specifications online.
Once you have the total wall surface area and the pattern repeat, you can calculate how many rolls of wallpaper are required for your project. The easiest way to do this is to use a wallpaper calculator.
However, these tools can be inaccurate and do not always account for different percentages of waste. To get a more accurate estimate it’s best to measure the walls yourself using the square-foot method, consider the pattern match and deductions for openings, and double check your calculation with a wallpaper retailer. This ensures that you order the right amount of wallpaper and get a beautiful, professional-looking result.
Calculate the Quantity
Using the surface area of your walls and the coverage per roll, you can calculate the number of rolls of wallpaper needed to cover the room. However, you should not forget to subtract the surface area of openings like doors and windows since they will need extra strips to accommodate for their height.
You can also use a calculator to find out the quantity of wallpaper required for your room. It takes into account the room’s surface area, pattern repeat and waste factors. It also provides a cost estimate and an estimation of how long it will take to hang the wallpaper.
You will need approximately 17 single or 9 double rolls of wallpaper to cover the walls of a 12×12 room including waste factors of around 10%. This will provide a total of 423 square feet of coverage. The amount of wallpaper needed for your room will vary depending on the size and shape of your walls, the type of pattern you choose and how much you plan to spend.
