Quilting Calculators

Easily master the math involved in quilting! Robert Kaufman Fabrics and Quilters Paradise have joined forces to bring you this updated collection of eight essential quilting calculators. Designed by quilters, the calculators work with both U.S. and metric measurements. With these tools you’ll easily and accurately work out how many rectangular pieces can be cut from a larger piece, or how much fabric is needed for backing, batting and borders, square-in-a-square, set-in and corner triangles, and more. We’ve also added an AI chatbot to answer your questions and give advice on every aspect of quilting. Our calculators: • Fabric Measurement Converter: Converts between measurement in decimals and fractions. • Backing and Batting Calculator: Determines how much yardage from a bolt of fabric is needed to make the backing for a quilt. • Piece Count Calculator: Shows the number of fixed-size pieces that can be cut from a larger piece of fabric. • Pieces to Yardage Calculator: Indicates how much fabric is needed in order to cut a given number of fixed-size pieces. • Binding Calculator: Tells you the amount of fabric required to bind your quilt, based on the quilt’s dimensions and the binding strip width. • Border Calculator: Shows the amount of fabric required to create borders, based on your quilt’s dimensions and the width of the borders. • Square-in-a-Square Calculator: Works out the key dimensions of a square-in-a-square block. • Set-in and Corner Triangle Calculator: Determines the size of the square piece you’ll need to cut in order to create both unfinished set-in triangles and corner triangles.
