Keep the estimate tied to your swatch. One cell is treated as one stitch and the yarn estimate scales from the yarn you entered for a measured swatch. Stitch type, floats, carrying colors, joining, borders, shaping, tension, and finishing can change actual use. This tool does not generate written construction instructions or guarantee a finished result.
Formula
Chart width and height are cell counts. Gauge-based inches = chart count × 4 ÷ measured count per 4 inches. Optional yarn totals scale user-entered swatch yardage by stitch count and buffer.
