How to Measure Your Walls for Wallpaper
Accurate measurements ensure the perfect fit and the right amount of wallpaper for your project.
Accurate wall measurements are the first step toward a successful wallpaper installation. Whether you're ordering wallpaper for a single accent wall or an entire home, taking the correct measurements helps ensure you purchase the right amount of material while minimizing waste and avoiding delays.
We recommend measuring the entire wall, not just the visible area. Our team can also verify your measurements before you place an order.
What You'll Need
Before measuring your walls, gather the following tools:
- Tape measure or laser measure
- Pencil
- Notepad or phone
- Step ladder for high ceilings
Measurements should always be taken in inches for the most accurate wallpaper calculation.
Step 1 – Measure the Wall Width
Measure the full width of each wall from corner to corner.
If you're wallpapering multiple walls, measure each wall individually rather than estimating the total room perimeter.
Step 2 – Measure the Wall Height
Measure from the finished floor to the ceiling at several locations.
If your ceiling height varies, always use the largest measurement. This ensures enough material for trimming during installation.
Step 3 – Include Windows and Doors
Do not subtract windows, doors, or other openings from your measurements.
Although these areas will not require wallpaper, the material removed is often needed to maintain the pattern repeat and ensure the design aligns correctly across the wall.
Step 4 – Measure Each Wall Separately
Even if two walls appear identical, always measure them individually.
Many homes have slight variations in wall width or ceiling height that can affect the wallpaper quantity required.
Common Measuring Mistakes
Avoid these common errors:
- Measuring only the visible wall area
- Subtracting windows and doors
- Estimating instead of measuring
- Forgetting ceiling height variations
- Ignoring pattern repeat requirements
- Ordering the exact calculated amount without professional verification
These mistakes often result in material shortages and installation delays.
