Knitting Increase Spacing Calculator

Distribute single increases as evenly as possible across a row or round. The calculator shows exactly how many existing stitches to work in each section between increases.

Method: existing stitches are divided into one more work section than the number of increases. Section boundaries are rounded to the nearest stitch, which keeps section sizes within one stitch of each other. This tool assumes each increase adds one stitch.

How to read the result

If the result says 9 · 9 · 9 · 8 · …, work the first number of stitches, make one increase, work the next number, make one increase, and continue. The last section is worked after the final increase.

When this calculator is useful

Use it when an instruction tells you to increase a stated number of stitches evenly across a row or round. It does not choose an increase technique for you; use the increase specified by your pattern.

Important limits

Shaping instructions can require increases at specific locations rather than even spacing. Raglan lines, lace, cables, colourwork and paired increases should follow the pattern construction rather than this general distribution.

Worked example

Starting with 20 stitches and adding 4 increases gives five equal work sections: 4 · 4 · 4 · 4 · 4. Work 4 stitches, increase 1, and repeat between sections. The final count is 24 stitches.

Common question

Why are there one more work sections than increases? Because an evenly distributed set of increase points has a section before the first increase and another after the last increase.
