Even Increase Spacing Calculator

Adding 8 stitches to a 60-stitch round: 60 ÷ 8 = 7.5, so you increase every 7th stitch. That spends 7 × 8 = 56 stitches and leaves 4 over. Those 4 are not waste — four of the eight gaps become 8 stitches instead of 7, and alternating 7, 8, 7, 8, 7, 8, 7, 8 hides them completely. You finish the round with 68.

Formula

Every n stitches = ⌊Stitches ÷ Increases⌋, Leftover stitches = Stitches − Every n stitches × Increases

Pile the remainder into one place and it bulges like a seam. Round the other way — "every 8th stitch" — and 8 × 8 = 64 leaves you 4 stitches short of the last increase. Working in the round, increases stacked at the same point every round line up into visible radial ridges; if that is not the look you want, shift the starting point a few stitches each round. For amigurumi, where the count is locked to multiples of the starting stitches, use the increase-rounds calculator instead.

Frequently asked questions

Q. How is Even Increase Spacing Calculator calculated?

Every n stitches = ⌊Stitches ÷ Increases⌋, Leftover stitches = Stitches − Every n stitches × Increases — Adding 8 stitches to a 60-stitch round: 60 ÷ 8 = 7.5, so you increase every 7th stitch. That spends 7 × 8 = 56 stitches and leaves 4 over. Those 4 are not waste — four of the eight gaps become 8 stitches instead of 7, and alternating 7, 8, 7, 8, 7, 8, 7, 8 hides them completely. You finish the round with 68.

Q. Can you walk through an example?

With Stitches 60sts, Increases 8sts, the answer is Every n stitches 7sts.

Q. What do I need to enter?

Enter Stitches, Increases. The result recalculates as you type, and an empty box counts as zero.

Q. How much does the answer move if I change a number?

Changing only Stitches (sts) moves the answer to Stitches (sts) 30 → Every n stitches (sts) 3 and Stitches (sts) 120 → Every n stitches (sts) 15. 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.

Q. Anything to watch out for?

Pile the remainder into one place and it bulges like a seam. Round the other way — "every 8th stitch" — and 8 × 8 = 64 leaves you 4 stitches short of the last increase. Working in the round, increases stacked at the same point every round line up into visible radial ridges; if that is not the look you want, shift the starting point a few stitches each round. For amigurumi, where the count is locked to multiples of the starting stitches, use the increase-rounds calculator instead.
