How to use your result
Gauge describes how many stitches and rows occupy a measured area. This tool converts those counts to stitches and rows per unit, then calculates a rectangle. It works for crochet or knitting when your sample and project use the same stitch pattern and construction. It does not generate a pattern.
Rows = target length × counted rows ÷ measured length
Rows are rounded to the nearest whole number, with a minimum of one. If you enter a repeat, stitches are rounded to the nearest valid multiple plus your edge stitches, with at least one full repeat. The displayed finished width and length show the effect of rounding.
Example: a 100 × 140 cm rectangle
If 18 stitches and 12 rows measure 10 × 10 cm, there are 1.8 stitches and 1.2 rows per centimetre. A plain rectangle needs about 180 stitches and 168 rows. If your fabric requires a multiple of six plus two edge stitches, the nearest valid count is 182 stitches: 30 repeats × 6 + 2. The estimated width becomes 101.1 cm.
Do I chain the displayed stitch count?
Not automatically. This result is the count of working stitches in a row. A pattern may need additional foundation chains, skipped chains or a turning chain that does or does not count as a stitch. Read the pattern’s setup instructions separately. “Multiple of six plus two” in a foundation-chain instruction may describe chains rather than the final number of working stitches.
Use the actual measuring window
If you count over four inches, enter four inches. Ten centimetres and four inches are close but not identical. Changing the unit selector converts the dimensions; it does not change how many stitches you counted. Include partial stitches when you can measure them reliably, and repeat the count in more than one central area.
A rectangular calculation cannot account for sleeves, neck shaping, increases or deliberate ease in a garment. It also cannot ensure that the final row lands on a complete pattern repeat. Adjust the result using the instructions for the specific project.
Measure a useful gauge swatch and understand stitch multiples before casting on or chaining.
