Estimate strips, rolls and cost with the drop/strip method (better for pattern repeats than simple area).
- Perimeter, wall height, opening width
- Roll width/length, pattern repeat, spare rolls and price
- Effective perimeter = perimeter − openings
- Drop length = height + repeat; strips/roll = floor(roll length ÷ drop)
- Strips needed = ceil(perimeter ÷ width); rolls = ceil(strips ÷ strips/roll) + spare
Plain: repeat ≈0; small pattern ~10 cm; large ~40 cm. Keep one spare roll from the same lot. Runs locally in your browser.
