Use a reviewed crown construction and check finished circumference, depth and stretch separately. Crown diameter alone does not establish fit for every shape.

## 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

If the chosen finished circumference is 52 cm at 20 stitches per 10 cm, the side section targets 104 stitches. Fit the crown’s permitted count before starting straight rounds.

## 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: 52 cm
- Target height: 30 cm
- Desired ease: 0 %
- Stitch multiple: 1
- Row multiple: 1
- Rounding policy: Nearest valid count
