1. What is a Wallpaper Measurement Calculator?

Definition: This calculator estimates the area of wallpaper needed based on wall height and width measurements.

Purpose: It helps homeowners and interior designers determine how much wallpaper is required for a wall or room.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( A \) — Area of wallpaper needed (square feet)
• \( H \) — Height of the wall (feet)
• \( W \) — Width of the wall (feet)

Explanation: The wall height is multiplied by the wall width to get the total surface area to be covered.

3. Importance of Accurate Wallpaper Calculation

Details: Proper measurement ensures you purchase enough wallpaper while minimizing waste and matching patterns correctly.

4. Using the Calculator

Tips: Measure each wall's height and width in feet. For multiple walls, calculate each separately and sum the results.

5. Frequently Asked Questions (FAQ)

Q1: Should I account for windows and doors?
A: Yes, measure their areas separately and subtract from total wall area for more accurate results.

Q2: How much extra should I order?

Q3: What if my wallpaper has a large pattern repeat?
A: You may need 20-25% more wallpaper to match patterns properly.

Q4: How do I measure wall height?
