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.

Inputs and Assumptions

Enter values that match your project or situation. The calculator uses the following fields and defaults; update them before relying on the estimate.

Project Length Required (inches): Default: 80 in
Project Width Required (inches): Default: 40 in
Fabric Roll Width Selection: Default: 45
Pattern/Shrinkage Buffer (%): Default: 10 %

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

Sewing curtains or drapes
Re-upholstering chairs and cushions

Expert Tips

When in doubt, round up by at least 1/2 yard. Leftover fabric scraps are always useful for test sewing or pocket liners.
