Measure walls for wallpaper
Wallpaper planning is usually easier from wall width and strip count than from area alone.
GuidesUnderstand pattern repeat in roll yield
A repeating design can increase the effective length of every strip.
GuidesCalculate strips per roll
Whole-strip yield can be more useful than square metres per roll.
GuidesDecide whether to order a spare roll
An extra roll is a risk-management choice rather than a mathematical requirement.
GuidesBuild a wallpaper project budget
Roll count is only the material core of the project.
