Pattern Repeat Calculator

Check if your stitch count fits a pattern repeat, find adjusted counts, and get a written cast-on formula with optional edge stitches.

Your Total Stitch Count

Pattern Repeat Size (sts)

Edge Stitches Each Side (optional)

Edge stitches are worked outside the pattern repeat on each side.

How to use

Enter your total stitch count — the number currently on your needles or that you plan to cast on.
Enter your pattern repeat size — for example, if the pattern says "8-stitch repeat," enter 8.
Optionally enter edge stitches per side — these are plain stitches that frame the pattern (e.g., selvedge stitches).
The result shows how many full repeats fit, how many leftover stitches there are, and the nearest valid counts.
The written formula shows how the stitches break down as a cast-on instruction.

Example: For a 100-stitch count with an 8-stitch repeat and 2 edge stitches each side:
Available for repeats = 100 − 4 = 96 stitches. 96 ÷ 8 = 12 full repeats, 0 leftover. Formula: "2 edge + (8 × 12) + 2 edge = 100 stitches."
