What this planner works out

This planner lists the row numbers on which to work each increase, decrease or pattern repeat, and gives the stitch count you should end with.

Writing the rows out before starting is what prevents the common failure of shaping — losing count and discovering it several centimetres later.

Plan shaping rows

Use this for

Sleeve shaping, waist shaping, raglan increases, lace repeats or reminders for rows where something changes.

Before you plan

Shaping evenly matters more than shaping exactly

A sleeve increasing every 10 rows and one increasing every 9 then 11 alternately reach the same count and look identical. What shows is bunching several increases together or leaving a long unshaped run before a cluster. Spreading them evenly is the goal; hitting exact row numbers is not.

How this calculator works

A list of rows and a resulting count:

Row for action i = start row + (i × interval), while within the end row
Final stitch count = starting count ± (actions × 2)
Increases add, decreases subtract, pattern repeats leave it unchanged

Actions falling beyond the end row are dropped rather than compressed, so a plan that does not fit shows fewer rows than requested — which is the signal to change the interval or extend the section.

Worked example: eight increases

Using the default figures — rows 1 to 80, 8 increases every 10 rows, starting from 60 stitches:

All eight fit within the 80 rows with nine rows to spare after the last. Ask for 9 increases at the same interval and the ninth falls on row 81, outside the section — the planner drops it and lists eight. That is the point at which the interval needs to come down to nine rows, which is easier to notice on a list than on the needles.

Common mistakes

Frequently asked questions

How do I keep track of rows?

A mechanical or app row counter, a tally on paper, or a locking stitch marker moved every ten rows. Marking the plan itself and ticking each shaping row as it is worked has the advantage of recording where you are in the shaping rather than just the row number, which is what matters when you pick the project up a fortnight later.

Should I increase at the edge or one stitch in?

One or two stitches in from the edge, usually. Working the shaping fully at the edge makes seaming harder and leaves a ragged line; a stitch or two in creates a neat visible line of shaping that many designs use deliberately. The pattern will specify where it expects the shaping to fall.

What if the shaping does not divide evenly?

Spread the remainder rather than clustering it. Working most increases every ten rows and a few every nine distributes the difference invisibly. Patterns often express this as a formula — increase every 10th row six times, then every 9th row twice — for exactly this reason.

Does this work for decreases too?

Yes, with the type set to decrease. The row list is identical and the final count falls rather than rises. Sleeve caps, raglans and waist shaping all use the same arithmetic, though raglans typically shape on four edges rather than two, so the count changes by four per row.

Is what I enter stored?

No. Figures are processed in your browser and never transmitted or retained.
