Measure total wall area, subtract doors/windows, divide by roll coverage (56 sqft per double roll). Add 10-20% for pattern matching waste.
Pattern repeat is the distance before the design repeats. Larger repeats (21-24 inches) create more waste. Straight matches are easier; drop matches need extra rolls.
One packet covers approximately 4-5 rolls. Pre-pasted wallpaper only needs water activation. Non-woven wallpaper uses paste applied to the wall instead.
