Calculating fabric yardage depends on the project and requires the use of basic mathematical calculations. There are also online fabric calculators that make the job easy.
A person may need to calculate fabric yardage to cover pillows, a couch, make drapes or sew a quilt. Understanding the size and scope of each project is a necessary first step. Start by measuring the length and width of the object. For three-dimensional items such as pillows or furniture, measure the depth as well. Be sure to leave enough overage of fabric for securing ends. Once the complete number of inches is calculated, divide by 36 to determine the number of yards required. Sites such as Warehouse Fabrics Inc. offer online yardage calculators and estimates that allow the user to determine the amount of fabric based on the type of project.
