Formula and limitations
Strips = round up(wall width ÷ roll width) + extra strips. Cut length = wall height + trim, rounded up to a full repeat for straight match. Strips per roll = round down(roll length ÷ cut length). Rolls = round up(strips ÷ strips per roll). Doors and windows are not deducted: offcuts may not form a usable full-height strip. Rounded ceilings, half-drop patterns, murals and mixed-height walls need a separate layout.
Estimates depend on your measurements and product labels. Confirm coverage and matching instructions before buying; these tools do not assess structural or surface safety.
