How to space increases or decreases evenly
- Enter the number of stitches you have on the needle or hook now.
- Enter the number of stitches you want after the shaping row.
- Read the change count, interval and instructions, then copy the result.
Examples
Increasing from 60 to 80 stitches
current 60, target 80
Increase 20, work 3 and make 1, repeat 20 times
Frequently asked questions
How do I increase evenly across a row?
Take the difference between your current and target stitches, then divide the current count by that difference and round down. That interval is how many stitches to work between increases.
What does the interval mean?
It is how many stitches to work before each increase or decrease. For decreases the tool works two of those interval stitches together, so the listed plain stitches are interval minus two.
Why is there a remainder note?
Stitch counts rarely divide perfectly. The remainder is the leftover stitches after the last shaping point, which you work plain so the changes stay spread across the row.
Does this work for both knitting and crochet?
Yes. The interval math is the same for both. Read make 1 as your preferred increase and work 2 together as your preferred decrease in either craft.
Is the spacing exact or an estimate?
It is an even estimate, not a strict chart. Patterns sometimes shift a stitch or two for symmetry, so adjust the first and last segments if you want the edges to match.
