Decrease Calculator — Evenly Spaced Decreases

Calculate how to space decreases evenly across a row for smooth shaping.

How We Calculate This

This calculator spaces decreases evenly across a flat row using the centred method, so no decrease lands at the selvedge.

The formula

Segments = Number of decreases + 1

Stitches per segment = (Current stitches − decreases × decrease width) / Segments

Each decrease (k2tog consumes 2 stitches) is worked at the end of an interior segment, and any leftover stitches are split evenly between the leading and trailing segments. Working in the round? Use Current stitches / Number of decreases instead, since there is no edge to protect.
