Here’s a step-by-step guide:

  1. Step-by-Step Guide to Measuring for Wallpaper

    1. Measure Wall Height

    Use a tape measure to measure from floor to ceiling. Round up to the nearest foot.

    2. Measure Wall Width

    Measure the width of each wall and round up to the nearest foot.

    3. Calculate Wall Area

    For each wall, multiply height × width.

    Formula: Wall Area = Height × Width

    4. Subtract Windows and Doors (Optional)

    • Standard door ≈ 20 sq ft

    • Standard window ≈ 15 sq ft

    👉 If your wallpaper has a busy pattern, it’s often best not to subtract small elements like windows to ensure enough material for pattern matching.

    5. Account for Pattern Repeat

    If your wallpaper has a repeat (e.g., 24”):

    • Straight match → add ~10% extra

    • Drop match (half-drop/random) → add ~15–20% extra

    6. Add Wall Areas Together

    Combine the square footage of all walls to get the total wall area.
