Graphgan Stitch Count Calculator

How this works

A graphgan is a pixel-crochet blanket: you work it in single crochet, one stitch for every square on the chart. So the design itself is simply width × height stitches — a 100-square-wide, 150-square-tall chart is 15,000 single crochet. A border adds a ring of stitches around all four sides, so it grows each finished dimension by twice its thickness (a 6-stitch border makes the blanket 12 stitches wider and 12 taller). That doubling is exactly the step that's easy to get wrong by hand, which is why this calculator separates the chart from the border for you.

Reading the breakdown

The result splits your total into chart stitches (the design) and border stitches (the frame around it). Keeping them apart helps mostly with planning: chart stitches map to the colors in your design, while border stitches are usually a single solid color you'll want to set aside extra yarn for. The finished size in stitches also tells you how wide your foundation row needs to be before you start.

Tips for an accurate count

• Count your chart squares carefully — that's the load-bearing input. A miscount of a few columns scales into hundreds of stitches.
• A standard border is 5–10 single crochet; many patterns specify the exact thickness.
• Your foundation chain is width + 1 — a small extra count we mention for completeness, but it isn't part of the total stitch count.
• For yarn estimation, pair this with the tapestry yarn calculator or the mosaic yarn calculator, depending on your technique.
