Wallpaper Yardage Calculator
When it comes to decorating your home with wallpaper, calculating the correct amount of wallpaper is essential to avoid wastage and additional costs. The wallpaper yardage calculator helps you determine how much wallpaper you’ll need by taking into account the dimensions of the walls and the repeat pattern of the wallpaper. The formula used is simple, making it easy for anyone to accurately estimate the required amount of wallpaper for their project.
Formula
The formula used for calculating wallpaper yardage (Y) is:
Y = (W * H * R) / 36
Where:
- W is the width of the wall in feet.
- H is the height of the wall in feet.
- R is the repeat pattern of the wallpaper in inches.
- The constant 36 is used to convert square inches into square yards.
How to Use
To use the wallpaper yardage calculator, follow these steps:
- Measure the width of the wall in feet (W).
- Measure the height of the wall in feet (H).
- Determine the repeat pattern (R) of the wallpaper in inches (this is the vertical pattern repeat).
After entering these values into the calculator, click the “Calculate” button to find out how much wallpaper you need in yards.
Example
Let’s say you have a wall with the following dimensions:
- Width (W) = 12 feet
- Height (H) = 8 feet
- Repeat Pattern (R) = 24 inches
Using the formula:
Y = (12 * 8 * 24) / 36
Y = 2304 / 36
Y = 64 yards
So, you would need 64 yards of wallpaper to cover the wall with the given repeat pattern.
FAQs
- What is wallpaper yardage?
- Wallpaper yardage refers to the amount of wallpaper needed to cover a wall or series of walls, measured in yards.
- How do I measure the width and height of the wall?
- Measure the width and height of your wall using a tape measure, ensuring you measure from one corner to the other.
- What is a repeat pattern in wallpaper?
- The repeat pattern is the distance between one pattern on the wallpaper to the same pattern next to it, typically measured in inches.
- Do I need to add extra wallpaper for cutting or mistakes?
- It’s a good idea to add extra wallpaper (typically 10-15%) to account for cutting errors or pattern matching.
- Can I use the calculator for multiple walls?
- Yes, simply calculate the yardage for each wall and then add them together to find the total yardage needed.
- Is the repeat pattern always in inches?
- Yes, the repeat pattern is generally measured in inches. If it is in centimeters, convert it to inches.
- Can I use the calculator for wallpaper with no repeat pattern?
- Yes, if there is no repeat pattern, you can set the repeat pattern value to zero.
- Why do I divide by 36?
- You divide by 36 to convert the result from square inches to square yards, as wallpaper is typically sold by the yard.
- Does this calculator account for windows or doors?
- No, the calculator assumes you are covering the entire wall. Subtract areas for windows and doors manually.
- What if I have a ceiling with wallpaper?
- For ceilings, measure the dimensions of the ceiling and apply the same formula, adjusting the height if necessary.
- Can I calculate wallpaper for rounded walls?
- For curved or rounded walls, use the circumference instead of the width of the wall.
- Should I measure from floor to ceiling?
- Yes, measure the height from the floor to the ceiling to get the correct vertical measurement.
- How do I adjust for a large repeat pattern?
- A large repeat pattern will require more wallpaper as the pattern must align correctly. This is why the repeat pattern value is included in the calculation.
- Do I need to measure every wall separately?
- Yes, if you are covering multiple walls, measure each wall individually and add up the total.
- How much extra wallpaper should I order?
- It’s generally recommended to order 10-15% more wallpaper than calculated to account for trimming and pattern matching.
- Can I use this for different types of wallpaper?
- Yes, this calculator works for any wallpaper with a pattern repeat. If the wallpaper is plain, the repeat pattern doesn’t apply.
- Is this calculation for standard rolls of wallpaper?
- Yes, the calculation assumes standard wallpaper rolls, which are usually about 27 inches wide and 30 feet long.
- Does wallpaper yardage include paste?
- No, this calculation only covers the wallpaper itself. You will need to purchase wallpaper paste separately.
- Can this be used for wallpaper borders?
- This calculator is intended for full-wall coverage, but you can use similar steps for wallpaper borders by measuring the length of the border needed.
- How do I calculate wallpaper for a feature wall?
- Measure only the area of the feature wall and apply the same formula.
Conclusion
A wallpaper yardage calculator is an essential tool for anyone looking to decorate their walls with wallpaper. By understanding the formula and accurately measuring your walls, you can easily determine how much wallpaper is needed. This helps avoid over-purchasing or running out of wallpaper during your project, making it easier to achieve a seamless and beautiful result.
