Formula and example
How it is calculated
Strips = round up(wall width / roll width); strips per roll = round down(roll length / strip length)
Worked example
For a 12 m wide, 2.5 m high wall with 0.1 m extra per strip and 0.53 × 10.05 m rolls, each roll gives three strips and eight rolls are needed.
Things to check
- Pattern repeat and matching are not included automatically. Adjust the allowance or calculate patterned strips separately.
