The knitting stitch increase & decrease calculator is an extremely valuable tool for calculating how to evenly increase or decrease stitches along a round or row of knitting.

​

Please note the following:

Only single increases and decreases can be made

OPTION 1: Is an M1 increase, but any increase that makes a new stitch in between stitches may be substituted

OPTION 2: Is a KFB, which may be substituted with any increase that works 2 stitches into a single stitch.

Decreases use K2tog, which may be substituted with with any decrease that works 2 stitches into 1 stitch.

​

Brackets

In knitting patterns, brackets [ ] indicate that a group of stitches should be repeated a certain number of times. For example, "[k6, m1] 4 times" means you should single knit6 stitches consecutively, then complete 1 m1 increase, and repeat that sequence 4 times. Brackets help simplify longer sets of instructions by keeping them concise.
