A stitch multiple is a way of saying that a motif needs a complete number of repeats. If each repeat uses six stitches, adding any arbitrary stitch count may leave a partial motif at the end. Extra edge stitches complete the row outside those repeats.
Read the instruction in context
“A multiple of six plus two” describes counts such as 8, 14, 20, 26 and 32. The repeated part comes first: 6 × the number of repeats. The two extra stitches are then added once, not once per repeat.
Four repeats of six plus two means 4 × 6 + 2 = 26. It does not mean 4 × (6 + 2) = 32. If a designer gives a chart, check what is inside the repeat box and what sits before or after it.
Combine the repeat with your gauge
Suppose your finished sample has 18 stitches per 10 cm and you want a 100 cm wide rectangle. The raw estimate is 180 stitches. With a six-stitch repeat and two edge stitches, 176 and 182 are both valid counts: 29 × 6 + 2 and 30 × 6 + 2. The closest is 182, giving roughly 101.1 cm.
For a pattern using six-stitch repeats with no extras, 180 is already valid. That small difference illustrates why you should copy the full repeat instruction, including any edge allowance, into a calculation.
Choose a rounding rule deliberately
The stitch calculator chooses the nearest full repeat and shows the resulting dimensions. If the desired raw count is exactly between two valid counts, it rounds upwards. If you need to stay below a strict width, choose the smaller valid count manually and verify the predicted width.
A very small target may be narrower than one full repeat. The tool keeps at least one repeat, so its output can be much larger than that target. That is a limitation of the chosen pattern, not something a fractional repeat can fix.
Working stitches are not always chains
The starting chain may include turning chains, skipped chains or setup spaces. A phrase about a “foundation-chain multiple” can refer to that starting chain, whereas this calculator treats the repeat as a count of working stitches. Read the designer’s setup row before translating a calculation into chains.
For example, a fabric with 26 working stitches might use a different starting-chain count depending on stitch height and whether the turning chain counts as a stitch. There is no single extra-chain number that is correct for all patterns. We deliberately leave that decision to the pattern instructions.
Do the same check vertically
Row repeats create a second constraint. A six-row motif may look incomplete if you stop after four rows of its final repeat. Our tool rounds row counts to whole rows, not whole row-pattern repeats. After calculating the length, adjust it to an appropriate stopping row and re-check the expected dimensions.
A useful note beside your project is: working stitches, foundation chains, full repeats and final row. Keeping these as separate entries makes counting mistakes easier to diagnose before they spread across a large piece.
