QuiltingCalc8.0.1 - App Store

Robert Kaufman Fabrics and Quilter's Paradise have joined forces to bring you a collection of eight essential quilting calculators.

With these calculators you'll be able to quickly convert between yards and inches, meters and centimeters; learn how much fabric you need for backing, batting and borders; and determine how many rectangular pieces can be cut from a larger piece. There are even calculators for square-in-a-square, set-in and corner triangles.

Here's a brief description of each calculator:

Fabric Measurement Converter: Converts between inches and yards in decimal form, and yards in fractional form. (With metric equivalents.)

Backing and Batting Calculator: Determines how much material from a bolt of fabric is needed to make the backing for a quilt.

Piece Count Calculator: Shows the number of fixed-sized pieces of fabric that can be cut from a larger piece.

Pieces to Area Calculator: Indicates how much fabric is needed in order to cut a given number of fixed-sized 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 a 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 unfinished corner triangles.
