This crochet decrease calculator helps determine how many stitches should be decreased evenly across rows or rounds. Enter the starting stitch count, final stitch count, and number of rows to estimate decreases per row.
How to use calculator
Enter the number of stitches you start with, the final stitch count you want after shaping, and the number of rows over which decreases will occur. The calculator estimates how many stitches should be decreased per row.
Explanation
Crochet decreases are used to shape garments, sleeves, hats, and other projects. By spreading decreases evenly across rows, the fabric tapers smoothly toward the desired stitch count.
Example math
If a project begins with 120 stitches and needs to decrease to 60 stitches over 10 rows:
120 − 60 = 60 stitches removed
Then divide by the number of rows:
60 ÷ 10 = 6 decreases per row
So you would decrease 6 stitches in each row.
