Increase and Decrease Evenly Calculator
Place M1 increases or k2tog decreases evenly across a flat row or round, with exact instructions and a visual strip.
Increase and Decrease Evenly Calculator: Divides the ordinary knit stitches into integer gaps, counting two consumed stitches for every k2tog. Round gaps differ by at most one stitch, including across the marker. Flat rows use half-gaps at each edge, balanced within one stitch. It supports up to 100000 starting stitches and 1000 changes.

K6, M1; *K7, M1* 2 times; K6, M1; *K7, M1* 2 times; K6, M1; *K7, M1* 2 times; K6, M1; *K7, M1* 2 times
K = knit; M1 = make one from the strand between stitches; k2tog = knit two together. A number after K is the number of stitches to knit. A repeat count includes the first repeat.
Spacing includes the gap across the round marker. An M1 at the end uses the strand across that marker on an established round.

Frequently asked questions
Why can I not decrease more than half?
Each k2tog consumes two old stitches and produces one. Larger reductions need several rows or another method such as double decreases.
Are the flat decreases mirrored?
Their positions are balanced within one stitch, but all k2tog stitches lean right. This calculator does not substitute ssk or preserve a rib or lace pattern.
Can I increase at an edge?
M1 uses an existing strand between stitches. Flat knitting keeps increases between the edges; a round can use the strand across the round marker. Use an established row or round.
