Gauge Conversion Calculator
Your gauge doesn't match the pattern? Recalculate any stitch count to fit.
Cast on 182 sts
200 sts at pattern gauge → 182 sts at your gauge
Both gauges must be measured over the same width — 10cm (4in) is the standard swatch.
How to use
- Knit or crochet a swatch and count how many stitches you get over 10cm (4in).
- Enter the stitch count the pattern specifies, the pattern's gauge, and your own gauge — measured over the same width.
- The result is the stitch count that gives you the same finished size at your gauge.
- Repeat for row counts if your row gauge also differs — the same ratio applies.
Good to know
- The two gauges must be measured over the same width (both per 10cm or both per 4in) — the calculator uses their ratio, so the unit itself does not matter.
- Rounding to the nearest stitch can shift the finished size by a few millimetres; round toward the nearest pattern-repeat multiple if your stitch pattern needs one.
- Changing needle size is often easier than recalculating a whole pattern — try matching gauge first, and convert only when you like your fabric as it is.
FAQ
- Why does gauge matter so much?
- A difference of just 2 stitches per 10cm on a 50cm-wide sweater is a 4–5cm size difference. Converting stitch counts (or matching gauge) is what keeps the finished measurements true to the pattern.
- Can I use stitches per inch instead of per 10cm?
- Yes — as long as both gauges use the same width. The calculator only uses the ratio between them, so per-inch and per-10cm both work.
- Do I need to convert row counts too?
- If the pattern says "knit for 20cm" you can just measure. But when it counts rows (e.g. for sleeve shaping), convert row counts with the same tool using row gauge.
