1. What is a Wallpaper Square Footage 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 (square feet)
• \( H \) — Height of wall (feet)
• \( W \) — Width of wall (feet)

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

3. Importance of Wallpaper Calculation

Details: Accurate area calculation helps purchase the right amount of wallpaper, minimizing waste and ensuring pattern matching.

4. Using the Calculator

Tips: Enter the wall height and width in feet. All values must be > 0. For multiple walls, calculate each separately and sum the results.

5. Frequently Asked Questions (FAQ)

Q1: Should I include doors and windows in my measurements?
A: No, measure the full wall dimensions. You'll subtract window/door areas after getting the total.

Q2: How much extra should I add for pattern matching?
A: Typically add 10-20% more to account for pattern repeats and mistakes.

Q3: What if my wall isn't rectangular?
A: Break it into rectangular sections, calculate each separately, then sum the areas.

Q4: How do I convert this to wallpaper rolls?
A: Divide total square footage by the coverage per roll (check product specifications).

Q5: Does this account for wallpaper waste?
A: No, always purchase 10-15% more than the calculated amount for trimming and errors.
