Use your crochet gauge swatch to instantly calculate the correct number of stitches, rows, and yarn required for any crochet project with this free crochet stitch calculator tool— perfect for blankets and scarves.
How many stitches do I need to make a __?
Before you start a crochet blanket, it’s important to know how many stitches you need to begin.
If you guess, your blanket could end up too wide, too narrow, or you might run out of yarn before you finish.
So, how do you avoid this?
Just use your gauge swatch and the Crochet Stitch Calculator below to get the exact number of starting stitches for your tension, even if you need to count by multiples. No complicated math needed.
This works for:
- Baby blankets
- Throw blankets
- Bed-size blankets
- Custom blankets
- Any stitch pattern
- Any yarn or hook
You don’t even need a pattern.
All you need is your gauge.
Step 1: Make a Gauge Swatch
First, crochet a small swatch, about 4 inches by 4 inches (or 10 by 10 centimeters) in your pattern stitch.
When you make your gauge swatch, use:
- The same yarn
- The same hook
- The same stitch you want to use for your pattern.
Then measure:
- How many stitches fit across 4″ (or 10cm)
- How many rows fit into 4″ (or 10cm)
Step 2: Choose Your Blanket Size (Or other project measurements)
If you are not working from a particular pattern, check the table below for a quick blanket size guide.
Standard Crochet Blanket Sizes
| Blanket Type | Width (in) | Height (in) | Width (cm) | Height (cm) |
|---|---|---|---|---|
| Lovey | 12–14 | 12–14 | 30–36 | 30–36 |
| Security Blanket | 14–17 | 14–17 | 36–43 | 36–43 |
| Stroller | 30–40 | 34–36 | 76–102 | 86–91 |
| Receiving Blanket | 40 | 40 | 102 | 102 |
| Baby Blanket | 42–52 | 52–60 | 107–132 | 132–152 |
| Lapghan / Throw | 50–65 | 60–80 | 127–165 | 152–203 |
| Twin Bed | 66–70 | 90 | 168–178 | 229 |
| Full / Queen Bed | 85–90 | 90–100 | 216–229 | 229–254 |
| King Bed | 108–120 | 90–100 | 274–305 | 229–254 |
Step 3: Use the Crochet Stitch Calculator
Enter:
Stitches in 4″ (or 10 cm)
Rows in 4″ (or 10 cm)
Desired blanket width
Desired blanket height
Optional:
Turning chains
Stitch multiple (if your stitch pattern requires a multiple repeat pattern, like 3, 4, 6, etc.)
The calculator gives you:
- Exact stitch count for your starting chain
- Total number of rows to crochet
- And adjustments if your stitch pattern must be divisible by a certain number
- This way, your blanket comes out the right size the first time.
No more guessing.
And hopefully, no frogging.
Step 4: Calculate How Much Yarn You Need
Now use the Yarn Calculator.
Enter:
Total stitches you have in your square
Swatch weight (grams)
Total stitches in the pattern you are making
Grams per skein
(Optional) meters per skein
And it will tell you:
Total grams needed to make your project
How many skeins of the yarn you entered to buy
How many meters you will need
This way, you get the most accurate yarn estimate, since it uses your actual gauge square stitch count.
