1. What is a Wallpaper Linear Yard Calculator?

Definition: This calculator estimates the total linear yards of wallpaper needed based on wall height and number of drops (wallpaper strips).

Purpose: It helps interior designers, decorators, and homeowners determine how much wallpaper to purchase for a project.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( LY \) — Linear yards of wallpaper needed
• \( W \) — Wall height (yards)
• \( \text{num\_drops} \) — Number of vertical wallpaper strips needed

Explanation: The wall height is multiplied by the number of drops (strips) needed to cover the wall width to get total linear yards.

3. Importance of Linear Yard Calculation

Details: Accurate calculation prevents over-purchasing wallpaper, ensures pattern matching, and helps with cost estimation.

4. Using the Calculator

Tips: Enter the wall height in yards and the number of drops (strips) needed. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I determine number of drops?
A: Divide total wall width by wallpaper roll width (accounting for pattern repeat).

Q2: What if my wall height is in feet?
A: Convert feet to yards by dividing by 3 (1 yard = 3 feet).

Q3: Does this include waste allowance?
A: No, add 10-15% to the calculated amount for pattern matching and trimming.

Q4: How do I account for doors/windows?
A: Calculate total wall area first, then subtract openings, or use our Wallpaper Area Calculator.

Q5: What's a typical wallpaper roll length?
A: Standard American rolls are about 5 linear yards, European rolls about 11 linear yards.
