Measure row density consistently
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
Turn a measured swatch into stitch and row counts for your finished size.
Before you use this tool
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.
Method and limits
Formula and assumptions
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.
Worked example
Example: 20 stitches across 10 cm becomes 100 stitches across 50 cm.
Limits and rounding
Results are planning estimates from the values entered. Displayed decimals are rounded for craft use; whole materials and repeats round up where the method says so. Confirm gauge, material behavior, construction, and finished measurements before committing supplies.
