How to Measure a Room for Wallpaper

June 4, 2026
How to Measure a Room for Wallpaper

Before choosing wallpaper, it's important to measure your room correctly. A few simple measurements can help ensure you order the right amount and avoid delays during installation.

 

Step 1: Measure Each Wall

Using a tape measure, record:

  • Wall height
  • Wall width

Measure each wall separately, even if they look similar.

Step 2: Calculate Wall Area

Multiply:

Wall Height × Wall Width = Total Wall Area

For example:

2.5m high × 4m wide = 10m²

Repeat for each wall and add the totals together.

Step 3: Don't Worry About Windows and Doors

For most projects, it's best not to subtract windows and doors. The extra material helps cover pattern matching and installation waste.

Step 4: Check Wallpaper Coverage

Every wallpaper roll covers a specific area. Coverage can vary depending on the collection and pattern repeat.

Step 5: Account for Pattern Matching

Large patterns often require additional material to align the design correctly. This may increase the number of rolls needed.
