Fabric Yardage Calculator for Cutting Pieces

Divide the fabric width by the piece width and round down to get how many pieces fit across a row. Divide the quantity by that and round up for rows, multiply by the piece length, then divide the inches by 36 for yards.

Use the usable width across the bolt after selvages. Quilting cotton is about 42 to 44 inches, so 44 is a common default. Many apparel and home fabrics run 54 or 60 inches.

Yes. Toggle the unit to cm and every measurement field switches over, converting your current values at 2.54 cm per inch. The result then shows total length in centimeters and a meters figure instead of yards.

No. The result is the exact layout for the piece sizes you enter. Add your seam allowance to each piece size first, and buy a little extra to cover shrinkage and squaring up.

Then it cannot be tiled across the width, so the tool places one piece per row, cuts along the length of the bolt, and shows an amber note. In the 50 by 30 inch example on a 44 inch bolt, two pieces need two rows and 60 inches of fabric.

No. Pieces are laid with the width you enter running across the bolt, without rotating. If turning a piece would tile more per row, swap the width and length values yourself and compare the two results.

Fabric is bought by continuous length, so any partial row still needs a full piece length of fabric. Rounding rows up makes sure every piece can be cut, even when the last row is not full.

Piece width, piece length, quantity and fabric width must all be greater than zero. A zero, blank or negative entry shows an error message instead of a layout, since none of those can produce a valid cut.

Yes. The calculation runs entirely in your browser and nothing is uploaded to a server, so your measurements and piece counts never leave your device.
