Quiltmath

Quilt size, cut list, binding and backing yardage from your block grid.

Quiltmath turns a block grid into the numbers you need at the cutting table: the finished size, every piece to cut, the binding and the backing. Type in your block size and how many blocks across and down, and a drawing of the quilt top, to scale, shows what you are planning while the sizes update.

Layout Enter the finished block size, columns and rows. Set a sashing width for strips between blocks, add sashing around the outside edge, and drop cornerstones where strips cross. Switch to an on-point setting to see the block diagonal (block size times 1.414) and the count of side and corner setting triangles. Add up to four borders, each with its own width, and watch the finished size grow.

Cut list Every strip, square and border piece is listed with a quantity and a cut size. A quarter inch seam allowance is added on each edge, so a cut size is half an inch more than finished. Border lengths are worked out one layer at a time, so a second border builds on the first. Share the whole list as plain text.

Binding Choose the strip width (2 1/2 inches to start), the usable fabric width and an allowance for joins and corners. Quiltmath adds the perimeter, counts the strips across the fabric width, and gives the fabric length rounded up to an eighth of a yard.

Backing Pick the overhang on each side and a fabric width: standard 42 to 44 inch cotton or 108 inch wide. You see how many panels you need with seams running down and across, which direction needs less fabric, and a small diagram of the seams.

More - Bed size starting points from crib to king that fit the grid to a target size. They are general guides, not exact sizes. - Save up to 30 quilts with their binding and backing settings. - Inches with eighth-inch fractions, or centimeters. - A plain-English guide to every step. - Reset everything with a confirmation.

Numbers are planning figures. Fabric widths, shrinkage and your own seam habits differ, so check against your pattern and buy a little extra.
