Sleeve Decrease Calculator
One decrease round takes a stitch off each side, so two stitches go at a time. Half the difference is the number of decrease rounds, and dividing the rows by that gives the interval.

Q. How much does the answer move if I change a number?
Changing only Starting stitches (sts) moves the answer to Starting stitches (sts) 36 → Every n rows (rows) 0 and Starting stitches (sts) 144 → Every n rows (rows) 2. 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.
