Assumptions & limits

Measure a representative washed or blocked swatch in the project’s stitch pattern. Counts round up to whole stitches and rows. Pattern repeats, edge stitches, shaping and changes in tension are not included.

Formula

stitches = ceil(S / sw × tw); rows = ceil(R / sh × th)

S: Stitches counted
R: Rows
sw: Measured swatch width
sh: Measured swatch height
tw: Target width
th: Target height

Worked example

S = 20; R = 28; sw = sh = 10 cm; tw = 50 cm; th = 60 cm → 100; 168.

Results show up to 8 decimal places. Small values use scientific notation; calculations use unrounded factors.
