Bedroom accent room
44 ft perimeter with standard 27 in rolls
A typical bedroom where door and window deductions help, but repeat-driven strip loss still matters.
Result: Pattern repeat often adds one or more rolls beyond a simple square-foot estimate
Wide-roll dining room
54 in roll width with no repeat
Wide rolls can reduce strip count materially even in larger rooms.
Result: Wider wallpaper can cut the order size even when the room itself is larger
