Count rows along the working axis and state whether ridges represent one or two rows. Measure a finished central area, not an unstable starting edge.

## Before you start

Gather the measurements, counts or timing sample needed below. Record their units and whether they describe a sample, the whole project or one purchased package. Use a finished sample when dimensions or material use depend on fabric structure.

## Try this example

A sample with 30 rows across 10 cm needs about 90 rows for 30 cm. A four-row repeat offers 88 or 92 rows; compare the resulting lengths.

## Check your result

- Recheck the inputs against the actual sample or label, keep units consistent and round only the final count or purchase. Repeat a sample if a small measuring difference changes the decision.
- These arithmetic examples assume the measured structure stays comparable. Shaping, borders, dense textures and color changes require their own allowances or samples.

## [Gauge & size planner](https://threadcabin.com/tools/gauge-size-planner)

Turn a measured swatch into stitch and row counts for your finished size.

Wash and rest a sample in the project’s stitch pattern. Count stitches and rows inside measured central spans, excluding edge distortion.  Positive ease adds room to the target width; negative ease subtracts it. The rounded result is a planning count; fit repeats and construction details before casting on.

Formula: stitches ÷ swatch width × target width after ease; rows ÷ swatch height × target height. Each result follows the selected up, down, or nearest rounding rule and its stitch or row multiple.

- Stitches: 20
- Rows: 30
- Swatch width: 10 cm
- Swatch height: 10 cm
- Target width: 30 cm
- Target height: 30 cm
- Desired ease: 0 %
- Stitch multiple: 1
- Row multiple: 1
- Rounding policy: Nearest valid count
