Crochet Increase Calculator — Even Increases per Round

Enter the stitch count you have and the one you need, and this writes the round for you — how many increases or decreases, how far apart, and the instruction in standard pattern notation. It also warns you when the change is too big for a single round, which is what makes a piece ruffle.

How to use it

1. Count what you actually have on the current round rather than trusting the pattern, especially if you have already lost or gained a stitch.
2. Enter your target count. The instruction below is written in standard notation you can follow directly.
3. Stagger the start point on the next shaping round so the increases do not stack.

A worked example

You have 48 stitches and the pattern’s next round needs 60. That is twelve increases across 48 stitches, so one increase every four: [3 sc, inc] × 12, which ends the round exactly on 60. On the round after, start the repeat two stitches later so the increases sit between the previous ones rather than on top of them.

Even shaping at a glance

This is the standard flat circle: six increases a round, spaced one stitch further apart each time.

Frequently asked questions

How do I space increases evenly in a round?

Divide the stitches you have by the number of increases to get the spacing, then work that many stitches between each one. Forty-eight stitches going to sixty needs twelve increases, so an increase roughly every four stitches: [3 sc, inc] × 12.

Why do my increases make visible lines?

Because they are stacked. If every increase in every round sits directly above the last, the fabric puckers into spokes. Shift the starting point by half a repeat on alternate rounds and the lines disappear.

Can I double the stitch count in one round?

You can, and it is standard at the very start of a flat circle, but past the first few rounds it ruffles badly. Spread it over two rounds instead.

What does [3 sc, inc] x 12 mean?

Work three single crochet, then two stitches into the next one, and repeat that whole sequence twelve times. It adds twelve stitches across the round.

Should increases go in the same stitch or next to each other?

Two stitches into one stitch is the standard increase and gives the flattest result. Working into the stitch either side leaves a small hole, which is sometimes wanted for lace and never wanted in amigurumi.
