Explanation
The size of a crochet blanket is determined by the number of stitches worked across and the number of rows completed.
Your gauge tells you how many stitches and rows fit within one inch of your crochet fabric. By multiplying your blanket dimensions by your gauge, you can estimate how many stitches and rows are needed to reach your desired size.
Example Calculation (Step-by-Step)
Let’s say you want to make a blanket that measures 40″ × 50″.
Step 1: Determine your gauge
4 stitches per inch
3 rows per inch
Step 2: Calculate stitches across
40 × 4 = 160 stitches
Step 3: Calculate rows needed
50 × 3 = 150 rows
👉 You would need approximately 160 stitches across and 150 rows to complete your blanket
Why this matters

Ensure your blanket reaches the correct size
Avoid running short or making it too large
