Use your washed and relaxed swatch to calculate the whole-stitch and whole-row counts required for a target width and length.
Unrounded basis: 105.6
count = measured count ÷ measured length × target length22 stitches across 10 cm for a 48 cm width gives 105.6, rounded to 106 stitches.
What the result means
The calculator scales measured stitch density to a target width. A result of 105.6 means the geometry calls for 105.6 stitch-widths; because only whole stitches can be worked, choose a deliberate count and reconcile it with the pattern repeat.
Centimetres or inches both work when the swatch width and target width use the same unit. Keep the unrounded result until the final step so a small early rounding error is not magnified across the project.
A dependable workflow
Measure washed or blocked fabric in its relaxed state and away from distorted edges. Calculate the raw count, choose a practical whole stitch, fit the repeat and then check the width that the selected count will actually create.
- Use the project stitch pattern, yarn and tool.
- Keep edge stitches separate unless the pattern includes them.
- Make a fresh swatch after changing a major variable.
How to use this page
- Measure stitches and rows across the centre of a blocked swatch.
- Enter the measured area and target dimensions in the same unit.
- Choose a practical whole-number result and fit it to your pattern repeat if needed.
What to check before you rely on the result
- Fractional stitches cannot be worked; select an intentional rounding direction.
- A different stitch pattern, needle, yarn or washing method can change gauge.
