1. What is the Wallpaper Yardage Calculation?

The Wallpaper Yardage Calculator determines how much wallpaper is needed for a project, accounting for pattern repeats and coverage area. It helps ensure you purchase the correct amount of wallpaper.

2. How Does the Calculator Work?

The calculator uses the yardage equation:

Where:

• \( wall\_area \) — Total area to be covered (square yards)
• \( adjustment\_for\_repeat \) — Additional area needed for pattern matching (square yards)
• \( coverage\_per\_yard \) — Area covered by one yard of wallpaper (square yards)

Explanation: The equation calculates total wallpaper needed by accounting for both the wall area and any additional material needed to match patterns.

3. Importance of Accurate Yardage Calculation

Details: Proper yardage calculation prevents purchasing too much or too little wallpaper, saving money and ensuring pattern continuity.

4. Using the Calculator

Tips: Measure wall area carefully, check manufacturer's specifications for pattern repeat, and verify coverage per yard. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

A: Calculate length × height for each wall, sum them, and convert to square yards by dividing by 9.

Q2: What is pattern repeat adjustment?
A: This accounts for extra wallpaper needed to match patterns at seams, typically 10-20% of wall area.

Q3: Where do I find coverage per yard?
A: This information is provided by the wallpaper manufacturer, usually on the product specifications.

Q4: Should I order extra wallpaper?
A: Yes, it's recommended to order 10-15% more than calculated for mistakes and future repairs.

Q5: Does this work for all wallpaper types?
