This crochet decrease calculator helps you determine how many stitches should be decreased evenly across rows or rounds to reach your desired stitch count.
Decreases are commonly used to shape crochet projects such as garments, sleeves, hats, and tapered pieces. Spreading decreases evenly helps maintain a smooth shape and prevents uneven or puckered fabric.
This calculator helps you plan your decreases so your project tapers evenly and stays balanced.

Explanation
In crochet, decreases are used to gradually reduce the number of stitches in a project. Instead of removing stitches all at once, decreases are spread evenly across rows or rounds to maintain the shape of the fabric.
This calculator determines how many stitches need to be removed overall, then divides that number by the number of rows or rounds to estimate how many decreases should be made in each row.
Example Calculation (Step-by-Step)
Let’s say a project starts with 120 stitches and needs to decrease to 60 stitches over 10 rows.
Step 1: Calculate total decreases needed
120 − 60 = 60 stitches
Step 2: Divide by number of rows
60 ÷ 10 = 6 decreases per row
👉 You would decrease approximately 6 stitches in each row
Why this matters
Planning decreases helps:
Create smooth and even shaping
Prevent uneven or puckered fabric
Maintain symmetry in your project
Improve overall accuracy
Tips for Working Decreases
Spread decreases evenly across each row
Use stitch markers to track decrease points
Follow pattern instructions when required
Check your stitch count regularly

Frequently Asked Questions
Do decreases need to be exact?
Even spacing is more important than exact placement.
What happens if I decrease unevenly?
Your project may lose its shape or look uneven.
Can I adjust decreases as I go?
Yes, but planning ahead gives more consistent results.
