Draft on your real wool ratio, never on 1:1 spreadsheet squares.
Knit stitches are wider than they are tall. StitchGrid calibrates every chart cell to your blocked 10 cm swatch, translates Japanese JIS, British UK, and German symbols without height or lean traps, and compiles deterministic RS/WS written rows offline.
True stockinette cell proportion; eliminates 21.4% vertical yoke squash.
28 verified stitch curves guarding UK dc -> US sc & JIS decrease leans.
100% deterministic local row compiler + Dynamic Island live counter.
Every stitch drawn to your true wool.
Proportional 4:5 charts, four-language Rosetta, and instant written rows.
Interactive Proportional Gauge & Rosetta Studio Bench
Drag the wool tension sliders, flip between 4:5 and 1:1, paint organic vector stitches, and compile rows in four languages right in the browser.
Selbu Eight-Petal Yoke Star
Calibrated 22 sts x 28 rows / 10 cm (Cell ratio 0.786)
Deterministic Row Compiler
US / UK / JIS / DE Trap Translator
Critical UK/US Trap: UK "dc" (double crochet) equals US "sc" (single crochet). Working a tall US double crochet ruins amigurumi & garment gauge.
Why circular yokes turn oval on square graph paper.
In standard DK stockinette (22 sts x 28 rows per 10 cm), each stitch measures 4.55 mm wide by 3.57 mm tall: a height-to-width ratio of 0.786. Drawing colorwork on square boxes compresses every motif vertically by more than one fifth on the needles.
