A 30 × 25 cm panel
A measured 10 × 10 cm area has 22 stitches and 30 rows. A 30 × 25 cm panel needs 66 stitches and 75 rows. A pattern written at 20 stitches per 10 cm would make a 30 cm panel only 27.27 cm wide at your measured gauge.
Let your swatch do the measuring.
Convert measured stitch and row gauge into a rectangular size, compare it with a pattern gauge, and see the effect of rounding.

The pattern reference size is a square: stitches across that width, rows across that height.

The intended size is 30 × 25 cm. This illustrates the gauge difference without rewriting the pattern.

How to use this result
- 01
Measure an interior section of the swatch and enter both its size and the counted stitches and rows. Half stitches or rows are allowed.
- 02
Set the desired finished rectangle and the comparison pattern gauge. The nearest whole stitch and row counts are shown with the sizes those rounded counts make.
- 03
Use the comparison to understand a gauge difference. It does not rewrite garment shaping, choose a needle size, or account for ease and seams.
THE TOOLKIT
Four small tools. One thoughtful project.
02
Evenly spaced shaping
Evenly distribute a row of increases or decreases without losing count.
Open calculator03Pattern repeats
Fit whole pattern repeats and two equal edges to a target width.
Open calculator04Swatch yarn estimate
Scale your real swatch weight into a rectangular project estimate.
Open calculatorIs 10 cm exactly 4 inches?
No. One inch is exactly 2.54 cm, so 4 inches is 10.16 cm. Switching units converts every physical length, including the pattern reference size; it does not replace a 10 cm reference with 4 inches.
Should I measure the whole swatch?
For stitch gauge, measure a representative interior section to reduce edge distortion. For the yarn estimator, use the whole weighed swatch area. These are different measurements.
Why is the rounded size slightly different?
A rectangle needs whole stitches and rows. The result rounds the raw counts to the nearest whole number, with a minimum of one, then calculates the achieved width and height.
