How this works
Row math is the vertical half of gauge. Multiply your desired finished length by your row gauge (rows per inch) and round to a whole number. We do that for you — and we round to your stitch pattern's vertical repeat if you have one.
Why row gauge is measured separately from stitch gauge
Most patterns specify row gauge and stitch gauge separately because rows-per-inch varies more than stitches-per-inch with your tension and the structure of the stitch. A pattern's "22 stitches and 30 rows over 4 inches" tells you both — and if your stitch count matches but your rows don't, your rows-per-inch is off and this calculator helps you plan around it. To work out the horizontal half — how many stitches to cast on for a target width — use the cast-on calculator.
What's a row multiple?
Many stitch patterns repeat over a fixed number of rows. K1P1 ribbing repeats every 2 rows. K2P2 ribbing repeats every 4. Moss stitch repeats every 8 (depending on the variant). Setting a row multiple ensures your row count finishes the pattern cleanly so you don't end mid-repeat.
Tips for getting accurate row gauge
- Knit the gauge swatch in your actual project stitch pattern, not stockinette.
- Wash and block the swatch — row gauge in particular shifts after blocking.
- Count rows across the middle of the swatch, not the edges (cast-on and bind-off rows distort). The gauge converter turns a 4-inch swatch count into rows-per-inch for you.
- If your row gauge is off but stitch gauge is right, plan for extra yarn — you'll need more length than expected.
