Knitting gauge comparison calculator

How to use this calculator

1. Enter your washed swatch span, stitch count and row count.
2. Enter the pattern gauge over its own span, using the same selected length unit.
3. Enter the pattern dimensions. The predicted rectangle keeps the pattern counts unchanged.

Will a looser gauge make my knitting bigger?

With the same stitch count, fewer stitches per measured length makes a wider piece. Fewer rows per measured length makes a longer piece. Compare both axes: matching stitch gauge alone does not establish row gauge or fit.

The calculation

New width = pattern width × pattern stitches per cm ÷ your stitches per cm. Apply the same calculation separately to rows and length.

A worked example

At 22 pattern stitches versus 20 actual stitches per 10 cm, a 50 cm width becomes 55 cm. At 30 versus 28 rows, 70 cm becomes 75 cm.

Before you cast on

This holds stitch and row counts constant. It does not redesign shaping, ease, necklines or sleeves. Enter both gauge spans explicitly: 4 inches is 10.16 cm, not 10 cm.

Measure a representative, washed and dried swatch without stretching it. See method sources and measurement guidance.

Display values round to 2 decimals; calculations keep full precision. Counts are whole numbers. No calculator can promise fabric behaviour.
