The Landscape Fabric Needed for an Area calculators computes the number of rolls of landscape fabric need to cover a rectangular area such as a garden or planter. 
INSTRUCTIONS: Choose units and enter the following:
- (L) Length of Area
- (W) Width of Area
- (FRW) Width of Fabric Roll
- (FRL) Length of Fabric Roll
Landscape Fabric Needed (LSF): The calculator returns the number of standard rolls of landscape fabric both 3'x50' and 6'x50'. The calculator also returns the size of the garden in square feet. However, this can be automatically converted to compatible units via the pull-down menu.
The Math / Science
The calculator computes the area to be covered and then computes the number of rolls of garden/landscaping fabric by dividing the area by the area in a standard roll of garden fabric. There are numerous manufacturers (8 listed) and the most common dimensions (12 listed) of garden fabric are:
A four sided area is considered a quadrilateral. The calculator computes the area of the quadrilateral using the length of the four sides and the diagonal. It then computes the number of rolls of garden/landscaping fabric by dividing the area by the area in a standard roll of garden fabric. There are numerous manufacturers (21 listed) and the most common dimensions (40 listed) of garden fabric are:
