QuiltCalc: Quilting Math

QuiltCalc is a free quilting calculator built for quilters who would rather sew than do maths at the cutting table. This quilting calculator works out yardage, strips and piece counts for the whole quilt, so you can buy the right amount of fabric the first time. WHAT IT CALCULATES • Backing yardage — enter the quilt top size, overhang and fabric width to get the backing size, panels to seam, yards to buy (including the turned layout when it uses less) and an estimated cost at your price per yard. • Batting size and binding — the batting size for your top, plus binding length, strip count and yardage for your strip width. • Border and sashing yardage — fabric needed for borders of any size and for sashing across a block grid. • Piecework math — half-square and quarter-square triangles, flying geese (4-at-a-time and traditional), square-in-a-square, on-point layouts, setting triangles and cornerstones. • Quilt sizing — finished size from blocks, sashing and borders; blocks needed for a target size; piece yardage, fat-quarter yield, precut pack yield and strips from a piece of fabric. • Everyday helpers — bias binding, t-shirt quilts, enlarge/reduce a block, shrinkage adjustment, a unit converter and a fraction helper for awkward measurements. YOUR QUILT PROJECTS • Save any calculator result as a named project with a note, so the numbers for each quilt stay together. • Copy a result or print it to PDF straight from the calculator. • Reference charts for common finished quilt sizes are built in. • Everything is saved on your device and works offline. A SHOP FOR QUILTING SUPPLIES The Shop tab gathers quilting fabric, tools and supplies from online sellers, so restocking starts where your math already lives. Prices and checkout stay with the seller. LISTEN WHILE YOU WORK Looking Glass Radio, our own live internet station, is built in — and off by default. Tap the ♪ button only if you want music while you quilt; tap again and it disconnects completely. Credit: background music made with lookingglassai.us.
