Measuring the amount of paintable wallpaper you need is a crucial step in any wall - covering project. As a paintable wallpaper supplier, I understand the importance of getting this right to ensure a smooth and cost - effective installation. In this blog post, I'll guide you through the process of accurately measuring the paintable wallpaper required for your space.

Step 1: Measure the Walls

The first and most fundamental step is to measure the walls where you plan to install the paintable wallpaper. You'll need a tape measure for this task.

Wall Height

Start by measuring the height of each wall from the floor to the ceiling. It's important to measure at several points along the wall, especially if the wall isn't perfectly straight. Record the highest measurement. This is because you'll need to ensure that the wallpaper can cover the entire height of the wall without any gaps.

Wall Width

Next, measure the width of each wall. Measure from one corner to the other at the base of the wall. If there are any alcoves, bay windows, or other irregularities, measure these sections separately. For example, if you have an alcove, measure the width of the alcove at the front and at the back, as well as the depth.

Once you have the height and width measurements for each wall, you can calculate the area of each wall. The formula for the area of a rectangle (which most walls approximate) is Area = Height × Width. For example, if a wall is 8 feet high and 12 feet wide, the area of the wall is 8 × 12 = 96 square feet.

If you have a wall with a door or window, you'll need to subtract the area of these openings from the total area of the wall. Measure the height and width of the door or window and calculate its area using the same formula. For instance, if a window is 3 feet high and 4 feet wide, its area is 3 × 4 = 12 square feet. So, if the wall with the window has an area of 96 square feet, the net area of the wall after subtracting the window area is 96 - 12 = 84 square feet.

Step 2: Account for Pattern Repeat

Many paintable wallpapers have a pattern repeat. A pattern repeat is the distance between where a pattern starts and where it repeats itself. When installing wallpaper with a pattern, you may need to match the pattern at the seams, which can result in some waste.

To account for pattern repeat, check the product information provided by the wallpaper manufacturer. They will usually specify the pattern repeat distance. As a general rule of thumb, for wallpapers with a small pattern repeat (less than 6 inches), you may need to add about 5 - 10% extra wallpaper to account for pattern matching. For wallpapers with a large pattern repeat (6 inches or more), you may need to add 15 - 20% extra.

Step 3: Consider the Wallpaper Roll Size

Paintable wallpapers come in different roll sizes. Common roll widths are 20.5 inches, 27 inches, and 36 inches, and common roll lengths are 33 feet.

To determine how many rolls of wallpaper you need, divide the total area of the walls by the area that each roll can cover. The area that a roll can cover is calculated by multiplying the width of the roll by its length. For example, if a roll is 20.5 inches (or approximately 1.71 feet) wide and 33 feet long, the area of one roll is 1.71 × 33 = 56.43 square feet.

Let's say the total area of your walls is 300 square feet. If each roll covers 56.43 square feet, then 300 ÷ 56.43 ≈ 5.32. Since you can't buy a fraction of a roll, you'll need to round up to 6 rolls.

Specific Room Considerations

Living Rooms

Living rooms often have larger walls and may have more complex layouts due to furniture placement and architectural features. When measuring for Paintable Wallpaper for Living Rooms, pay special attention to areas around fireplaces, built - in bookshelves, and entertainment centers. These areas may require custom cuts and additional wallpaper to ensure a seamless look.

Special Design Wallpapers

If you're considering Fashion New Design Paintable Wallpaper or Floral Design Paintable Wallpaper, the pattern repeat and the overall aesthetic of the design may influence your measurement and installation decisions. For example, floral designs may require more careful pattern matching to create a cohesive look.

Conclusion

Accurately measuring the amount of paintable wallpaper you need is essential for a successful wall - covering project. By following these steps and accounting for factors such as wall area, pattern repeat, and roll size, you can ensure that you purchase the right amount of wallpaper.
