Landscape Fabric Calculator

How to Calculate Landscape Fabric Requirements

The Landscape Fabric Calculator considers key parameters such as area length and width, fabric roll width, and overlap between rolls.

Formula:

Total Fabric Required = (Area Length × Area Width) ÷ Effective Roll Width
Where:

• Effective Roll Width = Fabric Roll Width – Overlap

Cost Estimation:
Total Cost = Total Fabric Required × Fabric Cost per Square Foot

This ensures you plan for precise material coverage without wastage.

Example Calculation:

You have a garden area of 30 feet by 20 feet. You’re using fabric rolls that are 6 feet wide, with an overlap of 0.5 feet between rolls. The cost of the fabric is $0.25 per square foot.

You need approximately 109.09 square feet of fabric, costing $27.27.

Common Fabric Roll Dimensions

• 3 ft × 50 ft (150 sq ft coverage)
• 4 ft × 100 ft (400 sq ft coverage)
• 6 ft × 300 ft (1800 sq ft coverage)

These standard sizes help streamline your planning process.
