À propos de cette calculatrice

Strips needed = room perimeter ÷ roll width (rounded up). Each strip is the wall height plus the pattern repeat. The number of strips per roll is the roll length ÷ strip length, and rolls = strips ÷ strips per roll. Openings reduce the strips slightly; a spare roll is wise.
