Stripe Repeat Calculator
160 rows with a 12-row repeat gives 13 repeats (156 rows) and 4 rows left. What matters is where those 4 rows go. Spread them a little at a time and one stripe ends up visibly fatter than the rest. Put them all somewhere that is already interrupted — just above the hem rib, or under the arm — and nobody finds them.

Formula
Full repeats = ⌊Rows ÷ Rows per repeat⌋, Leftover rows = Rows − Full repeats × Rows per repeat
An odd number of rows per repeat means a two-colour stripe starts at the opposite end each time, forcing you to cut the yarn. Keep the repeat even and the resting colour can be carried up the side, which halves the ends you have to weave in.

Frequently asked questions
Q. How is Stripe Repeat Calculator calculated?
Full repeats = ⌊Rows ÷ Rows per repeat⌋, Leftover rows = Rows − Full repeats × Rows per repeat — 160 rows with a 12-row repeat gives 13 repeats (156 rows) and 4 rows left. What matters is where those 4 rows go. Spread them a little at a time and one stripe ends up visibly fatter than the rest. Put them all somewhere that is already interrupted — just above the hem rib, or under the arm — and nobody finds them.
Q. Can you walk through an example?
With Rows 160rows, Rows per repeat 12rows, the answer is Full repeats 13.
Q. What do I need to enter?
Enter Rows, Rows per repeat. The result recalculates as you type, and an empty box counts as zero.
Q. How much does the answer move if I change a number?
Changing only Rows (rows) moves the answer to Rows (rows) 80 → Full repeats 6 and Rows (rows) 320 → Full repeats 26. The table below lays out five steps.
Q. How are the numbers rounded?
Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.
Q. Anything to watch out for?
An odd number of rows per repeat means a two-colour stripe starts at the opposite end each time, forcing you to cut the yarn. Keep the repeat even and the resting colour can be carried up the side, which halves the ends you have to weave in.
