Calculate rolls of wallpaper needed and total cost
1. Measure walls: Enter the width and height of each wall. For multiple walls of the same size, set the count.
2. Roll details: Check your wallpaper packaging for roll width (usually 20.5" or 27"), length (typically 33 ft), and pattern repeat.
3. Pattern repeat: If the wallpaper has a repeating pattern, enter the repeat distance. This affects how many strips you can get from each roll.
4. Buy extra: Always purchase 1-2 extra rolls for mistakes and future repairs. The calculation includes a small buffer.
