Crochet increase & decrease calculator

Enter your stitch counts. See exactly where to increase or decrease.

Your stitch counts

An increase works 2 stitches into 1 existing stitch. A decrease works 2 existing stitches together into 1. Instructions use plain language, not US/UK stitch abbreviations.

EVENLY SPACED STITCH CHANGES

Where do I put the increases?

The change is the difference between your target and current counts. We reserve one existing stitch for each increase, or two for each decrease. The remaining stitches are worked normally and spread between the changes.

60 stitches → 66 stitches
Work 9 normally, increase in the next.
Repeat 6 times.

For 66 → 60, work 9 normally, then work the next 2 together. Repeat 6 times: 54 ordinary stitches plus 6 decreases use all 66 old stitches and produce 60 new stitches.

When counts do not divide evenly, the normal-stitch runs differ by at most one. In flat mode we split the first run between the beginning and end. The numbered steps are in working order. “Existing stitches” always means positions in the original row, not newly made stitches.

COMMON QUESTIONS

Follow your pattern first.

What does “increase evenly” mean?

Spread the increases across the row or round rather than putting them all together. This tool gives one mathematically balanced arrangement; your pattern may require changes in particular places.

Why can’t I reach my target in one row?

With only 2-into-1 increases, you can at most double the starting count. With only 2-together decreases, the smallest possible target is half the starting count, rounded up. Larger changes need a different technique or more rows.

Does this make a flat circle?

Not by itself. The number of increases needed depends on the stitch, yarn, tension and shaping. This tool distributes a change you already chose; it does not choose the correct count for a circle or guarantee a shape.

Does it count turning chains or slip-stitch joins?

No. Enter only the working stitches counted by your pattern. Follow its instructions for turning chains, joins and whether they count as stitches. The calculator assumes each ordinary stitch consumes one existing stitch and makes one new stitch.
