How to crochet a blanket
To crochet a blanket, choose a size and yarn, crochet a gauge swatch, and calculate the foundation chain from stitches per inch multiplied by the target width. Work rows of one stitch, such as half double crochet, until the blanket reaches the target length, then add a border and weave in the ends.

What is the easiest blanket to crochet?
The easiest blanket to crochet is a rectangle worked in rows of half double crochet or double crochet in bulky or super bulky yarn. One stitch, no shaping and thick yarn produce fast results.
How many chains do you need to start a blanket?
The number of chains to start a blanket equals stitches per inch from your swatch multiplied by the blanket width, plus the turning chain.
| Stitches per 4 in (10 cm) | Stitches per inch | Chains for 50 in width |
|---|---|---|
| 10 | 2.5 | 125 |
| 12 | 3 | 150 |
| 14 | 3.5 | 175 |
| 16 | 4 | 200 |
How do you crochet a simple blanket step by step?
Crochet a simple blanket by working a foundation chain, then turned rows of one stitch until the blanket reaches length.
- Crochet a 6 × 6 inch swatch in half double crochet and measure stitches per 4 inches.
- Calculate the foundation chain for the target width, for example 150 chains for 50 inches at 12 stitches per 4 inches.
- Chain the calculated number plus 1.
- Work 1 half double crochet into the 2nd chain from the hook and each chain across.
- Chain 2 and turn; work 1 half double crochet in each stitch across.
- Count stitches every 10 rows to keep edges straight.
- Repeat rows until the blanket measures the target length, for example 60 inches for a throw.
- Work 2–3 rounds of single crochet around all edges, with 3 sc in each corner, as a border.
How long does it take to crochet a blanket?
A crochet throw takes roughly 20–40 hours in medium worsted yarn and roughly 8–15 hours in super bulky yarn, depending on stitch choice and speed.
These ranges are rough planning figures; tall stitches and thick yarn finish fastest.
How do you keep blanket edges straight?
Keep blanket edges straight by placing a stitch marker in the first and last stitch of each row and counting the stitches regularly. Wavy edges usually mean stitches were added or missed at row ends.
