Gauge Converter
Knitting at a different gauge than the pattern? Tell us both gauges and the pattern's stitch and row counts — we'll give you the adjusted counts that keep the finished dimensions the same.

How this works
The pattern's stitch count assumes the pattern's gauge. If you knit looser or tighter, that same stitch count gives you a different finished size. We compute the pattern's intended finished size (stitches ÷ gauge, rows ÷ gauge), then convert that size back into stitch and row counts at your gauge. Same finished piece, different counts.
Why this matters more than people think
Even a small gauge difference compounds. A pattern at 5 stitches per inch with 100 stitches (use the cast-on calculator to find that number) makes a 20-inch piece. If you knit at 5.5 stitches per inch and don't adjust, that 100 stitches becomes 18.2 inches — almost two inches small. Gauge math is the difference between a sweater that fits and one that doesn't.
Pattern gauge vs. your gauge: which one is "wrong"?
Neither. The pattern's gauge is just an assumption the designer picked. Your gauge is your gauge — it depends on your yarn, your needles, and your tension. If you love your fabric at your gauge, don't fight it. Adjust the counts instead.
Tips for accurate gauge measurement
- Knit a swatch at least 4 inches × 4 inches in the pattern's stitch pattern.
- Wash and block the swatch the way you'll wash the finished piece — both gauges shift.
- Measure across the middle of the swatch, not the edges.
- Measure stitches and rows separately — they often differ in how much your tension affects them.
- If your stitch gauge is right but row gauge is off, you can either adjust counts (use this calculator, or the row-count calculator to apply your converted row gauge to a specific length) or use a stretchier stitch pattern that disguises row differences.
