Your blocked gauge is the number that belongs in the calculator
A cast-on can be mathematically perfect and still fit badly if the gauge came from an unfinished swatch.

Use blocked stitches and rows per four inches or ten centimetres. We calculate the raw counts, then round the cast-on to your chosen repeat and show the resulting finished width.
Repeat-safe count
Check fabric direction, pattern instructions, and real material before cutting.
Before you cut
The result is a planning estimate, not a substitute for the pattern, the material in front of you, or the requirements of your quilter. Keep these boundaries with the printed plan.
Gauge should be measured from a washed and blocked swatch.
The repeat field covers the main fabric only; add edge and selvedge stitches separately.
Shaping, negative ease, and pattern-specific instructions still take priority.
