How to Calculate: Formula & Steps

Finds the required panel count matching project widths with fabric roll widths, multiplies by length, and divides by 36 to convert inches to yards.

Formula Used:Yards = [Project Length (in) × Number of Panels] ÷ 36

Step-by-Step Calculation Example

Making a project 80 inches long and 40 inches wide on standard 45-inch roll fabric requires 2.22 yards of fabric.

Common Mistakes to Avoid

Failing to align fabric print patterns (repeat patterns), which requires ordering 15% to 20% more material to align seams.

Practical Use Cases
