Knitting Gauge Calculator

How to use

1. 1Pick a mode: measure a swatch to find your gauge, resize a pattern to your gauge, or get stitch counts for a finished size. Choose inches or centimetres.
2. 2To find your gauge, count the stitches across a measured width and the rows up a measured height of a flat swatch, then read stitches and rows per inch and per 10 cm.
3. 3To resize a pattern, enter the pattern's stated gauge, your own gauge, and the cast-on or stitch count, and the tool rescales it so the finished width stays the same.
4. 4To plan a size, enter the finished width and optional length, and the tool returns the cast-on stitches and rows to knit at your gauge.
5. 5Round the cast-on to your stitch-pattern repeat if needed, then use Copy result. Everything is calculated in your browser.

About this tool

Gauge, also called tension, is the number of stitches and rows that fit in a measured span of knitted or crocheted fabric, and it is the single setting that decides whether a finished piece comes out the size the pattern intended. Two knitters can follow the same pattern with the same yarn and the same needle size and still end up with sweaters that differ by inches, because how tightly each person knits changes how many stitches land in an inch. This calculator handles the gauge math for all three of the situations makers actually run into, and it works for knitting and crochet alike since both quote gauge the same way. The first mode turns a swatch into a gauge: you count the stitches across a measured width and the rows up a measured height, and the tool reports stitches and rows per inch, per 10 centimetres, and per 4 inches, which are the three ways patterns and yarn ball bands state gauge, so you can compare your result against any of them without converting by hand. The second mode resizes a pattern to your gauge: you enter the gauge the pattern was written for, your own gauge from your swatch, and a cast-on or stitch count from the instructions, and the tool rescales that count by the ratio of the two gauges so the piece keeps the same finished width while using the number of stitches your tension needs. It does the same for an optional row count, and it shows the finished width both ways so you can see that the size is preserved and only the stitch count moves. The third mode goes from a measurement to a count: you give a finished width and optional length, and the tool multiplies by your gauge to tell you how many stitches to cast on and how many rows to knit, which is how you design a plain scarf, blanket, dishcloth, or any rectangle from scratch or adapt one to a size a pattern does not list. Inches and centimetres are both supported, the exact unrounded figure is shown next to every rounded count so you can round up to a stitch-pattern repeat yourself, for example a multiple of four for a two by two rib, and empty or invalid entries produce a clear message instead of a wrong number. A larger swatch always gives a more reliable gauge than a small one, and washing and blocking the swatch the way you will treat the finished piece matters because many yarns relax or grow after their first wash, so measure the blocked swatch when you can.
