Wallpaper Yardage Calculator








Required Yardage for Wallpaper: 0 yards



When it comes to decorating a room, wallpaper can be a beautiful and transformative choice. Whether you are refreshing a single wall or covering an entire room, calculating the right amount of wallpaper is essential to avoid purchasing too much or too little. Overestimating can result in unnecessary expenses, while underestimating can leave you short of wallpaper, leading to delays and potentially mismatched patterns.

Our Wallpaper Yardage Calculator is a practical tool designed to help you accurately determine the amount of wallpaper you need based on your wall dimensions and the repeat pattern of the wallpaper. This calculator provides an easy and efficient way to ensure you purchase the correct amount of wallpaper for your project, saving time, money, and potential frustration.


How the Wallpaper Yardage Calculator Works

To use the Wallpaper Yardage Calculator, you will need to input three key pieces of information:

  1. Wall Width (in inches):
    The total width of the wall you intend to cover with wallpaper.
  2. Wall Height (in inches):
    The height of the wall from the floor to the ceiling.
  3. Repeat Pattern (in inches):
    This refers to the height of the repeating design on the wallpaper. For wallpapers with patterns, the repeat pattern is critical because it determines how much additional wallpaper is required to ensure the design aligns correctly across the wall.

Once you input these values, the tool will automatically calculate the required yardage of wallpaper needed to cover the area. The result is rounded up to the nearest whole yard, ensuring that you have sufficient material to complete your project.


Formula Behind the Calculation

The formula used by the Wallpaper Yardage Calculator is designed to account for the size of the wall, the pattern repeat, and the necessary adjustment for full wallpaper rolls.

The formula is:

Yardage = (Wall Width × Wall Height × Repeat Pattern) / 36

Where:

  • Wall Width is the width of the wall in inches.
  • Wall Height is the height of the wall in inches.
  • Repeat Pattern is the repeat length of the wallpaper pattern in inches.
  • 36 is the constant used to convert square inches into yards, as there are 36 inches in a yard.

This formula accounts for the total area to be covered and adjusts for the repeat pattern to ensure the wallpaper design matches correctly when hung.


Step-by-Step Example

Let’s walk through an example of how the Wallpaper Yardage Calculator works using some sample values.

Example:

  • Wall Width: 120 inches
  • Wall Height: 96 inches
  • Repeat Pattern: 24 inches

Using the formula:

Yardage = (120 × 96 × 24) / 36
Yardage = 276,480 / 36
Yardage = 7,680 square inches

Now, we convert this to yards by dividing by 36 (since there are 36 inches in a yard):

Yardage = 7,680 / 36 = 213.33 yards

The tool will round this up to the nearest whole number, giving you 214 yards of wallpaper required for the wall.


Benefits of Using the Wallpaper Yardage Calculator

20 Frequently Asked Questions (FAQs)

1. What is a repeat pattern in wallpaper?
The repeat pattern refers to the vertical length of the design that repeats itself on the wallpaper. This is important to ensure the wallpaper’s design lines up correctly when installed.

2. How do I measure the wall for wallpaper?
Measure the width and height of the wall in inches. Make sure to measure accurately from corner to corner and floor to ceiling.

3. What does the calculator take into account?
The calculator accounts for the wall dimensions (width and height) and the repeat pattern of the wallpaper to determine the total yardage required.

4. How do I round up the yardage?
The calculator automatically rounds up the result to the nearest whole yard to ensure you have enough material.

5. Do I need the repeat pattern if my wallpaper is plain?
No, the repeat pattern is only necessary for wallpapers with a repeating design. For plain wallpaper, it can be ignored.

6. Can I use this calculator for other types of wallpaper?
Yes, the calculator can be used for any wallpaper, whether it’s plain or patterned.

7. Is this calculator accurate?
Yes, it uses a proven formula that provides accurate results based on the wall and pattern measurements you provide.

8. How many rolls of wallpaper do I need for my room?
The calculator provides the required yardage. You can then convert this value into the number of rolls needed based on the size of the wallpaper roll.

9. What is the standard wallpaper roll size?
The standard roll size is usually around 21 inches wide by 33 feet long, which is equivalent to about 56 square feet.

10. How do I calculate the number of rolls I need?
Divide the total required yardage by the number of yards per roll (typically 3 yards per roll).

11. Can this calculator be used for wallpapering doors or windows?
Yes, simply subtract the area of doors or windows from the total wall area before calculating the required yardage.

12. What if my wallpaper is a custom size?
You can still use the calculator as long as you have accurate measurements for the wall width, height, and pattern repeat.

13. Why is pattern repeat important?
Pattern repeat ensures that the wallpaper design aligns correctly from one piece to the next. Ignoring it may result in mismatched designs.

14. Can I use this calculator for wallpapering multiple walls?
Yes, simply calculate the area of each wall and add them together to get the total yardage.

The estimate is highly accurate based on the dimensions and repeat pattern provided, though slight variations may occur based on wall irregularities.

16. Can I use the calculator for ceilings or large surfaces?
Yes, the calculator works for any flat surface, including ceilings. Just input the correct dimensions.

17. Do I need to account for waste?
It’s always a good idea to order an extra 10-15% of wallpaper to account for wastage due to trimming or mistakes.

18. What should I do if my wall is not a perfect rectangle?
For irregularly shaped walls, estimate the average height and width, or break the wall into smaller sections and calculate each one separately.
