Enter the number of stitches on the needle, the number of rows to decrease over, and the number of decreases per row into the calculator to determine the remaining stitches on the needle.

Crown Decrease Formula

The following formula is used to calculate the remaining stitches on the needle after crown decreases.

RS = S - (R * D)

Variables:

  • RS is the remaining stitches on the needle
  • S is the initial number of stitches on the needle
  • R is the number of rows to decrease over
  • D is the number of decreases per row

To calculate the remaining stitches, subtract the total number of decreases (rows multiplied by decreases per row) from the initial number of stitches on the needle.

What is Crown Decrease?

Crown decrease is a knitting technique used to shape the top of a hat or the crown of a knitted item. It involves systematically reducing the number of stitches over several rows to taper the fabric and close the top of the hat. This technique is essential for creating a snug and comfortable fit, as well as for the aesthetic finish of the knitted piece.

How to Calculate Crown Decrease?

The following steps outline how to calculate the remaining stitches after crown decreases.


  1. First, determine the initial number of stitches on the needle (S).
  2. Next, determine the number of rows to decrease over (R).
  3. Next, determine the number of decreases per row (D).
  4. Next, gather the formula from above = RS = S – (R * D).
  5. Finally, calculate the remaining stitches (RS).
  6. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

initial number of stitches on the needle (S) = 100 stitches

number of rows to decrease over (R) = 10 rows

number of decreases per row (D) = 2 decreases/row
