Knitting Gauge Calculator
Your swatch against the pattern’s gauge: every stitch and row count converted to yours, plus a true-size gauge card.
Knitting gauge calculator by Envelo GaugeShift: your swatch against the pattern’s gauge, and every stitch and row count of the pattern turned into yours – with a true-size gauge card to print.
Your swatch has 21 stitches where the pattern says 22? Knit as written, the sweater comes out a size bigger. GaugeShift works out your gauge from the stitches and rows you count, shows the difference, and converts the pattern’s numbers to your gauge – keeping stitch repeats like «multiple of 4 plus 2».

What it does
What you can do
- Enter the stitches and rows you counted on your swatch and the width and height they cover, in cm or inches, fractions too
- Enter the pattern’s gauge over 10 cm (4 in) and see the difference in % – match, looser or tighter – and what to try
- Type the pattern’s stitch and row counts and get yours, with stitch repeats kept
- Type a width and get the stitches to cast on, a length and get the rows, or see how wide a number of stitches comes out
- A true-size gauge card, 180 × 140 mm, with centimetre and inch rulers and a 10 cm window: download as SVG or print at 100 % on A4 or US Letter
- The converted numbers as a CSV table, backup and restore
Example inside
A made-up sweater front from a made-up pattern at 22 stitches and 30 rows over 10 cm. The swatch has 31 stitches and 42 rows over 15 cm – 20.7 stitches and 28.0 rows over 10 cm, 5.91 % and 6.67 % under the pattern. Cast on 100 (multiple of 2) becomes 94, the body 110 becomes 103, 120 rows to the armhole become 112, a lace panel of 37 (multiple of 6 plus 1) stays 37.
