Rowsmith

Tool 2 of 4 · Gauge Converter

The pattern’s numbers, at your gauge.

Measure your washed swatch, put it beside the pattern’s gauge, and paste in the counts you need. Rowsmith converts each one and shows the size it will come out.

Gauge measured over
Up to 10, separated by commas: cast-on, stitches at the underarm, and so on.
Needs both row gauges.
A pattern written for “a multiple of 4 sts plus 2” needs counts like 106 or 110. Leave the repeat blank if there is none.

Width = stitches ÷ stitches per in.Swatch, wash and measure before trusting any gauge.

How it is worked out

Each pattern count is multiplied by your gauge divided by the pattern’s gauge: 120 stitches at 20 per 4 inches covers 24 inches, and 24 inches at 18 per 4 inches is 108 stitches. Rows work the same way with the row gauges.

With a stitch repeat, the nearest count that is a multiple of the repeat plus the extra stitches is shown; when two are equally near, both are.

Changing needles instead

If your gauge is close but not exact, many knitters change needle size and swatch again rather than rewrite the pattern: more stitches per 4 inches than the pattern means trying a larger needle, fewer means a smaller one. Converting the numbers is the other way, and it is the only way when you change yarn on purpose.
