How it is calculated
Take doors out of the perimeter beforehand. Matching a large pattern beyond the repeat — a half-repeat shift, for example — is not modelled here.
Rolls = round up(strips / strips per roll)
Where the numbers come from
- Wall perimeter — unit in the field: m
- Strip height — unit in the field: m
- Roll width — unit in the field: m
- Roll length — unit in the field: m
- Pattern repeat — unit in the field: m
Example
A perimeter of 12 m, a height of 2,5 m, and a roll of 0,53×10,05 m with no pattern repeat: 23 strips, 4 to a roll, so 6 rolls.
Questions
Is the width 1,06 m?
Enter it instead of 0,53.
Are there fewer strips in a roll because of offcuts?
Increase the pattern repeat or the height so the strip gets longer.
A ceiling?
This screen is about walls. For a ceiling, swap the perimeter for the layout length yourself.
