How many rows in a temperature blanket?

365 rows, one per day, or 366 in a leap year. How long that makes the blanket depends on your stitch: from about 3 ft in DK garter stitch to over 17 ft in double crochet.

Blanket length for 365 rows

One row per day, measured at typical gauges. Your own row gauge will vary, so check it on a swatch.

Keeping the length sensible

A throw is usually 50–70 in / 125–180 cm long. At one row per day, knitted stitches come out shorter than that (about 3–5 ft / 1–1.5 m), single crochet and grit stitch land close to it (6–7½ ft / 1.8–2.3 m), and half double and double crochet run far too long.

  • Knitting coming out short? Work two rows per day (the high and the low), or use a thicker yarn.
  • Crochet coming out long? Choose a short stitch such as single crochet or grit, or a thinner yarn: DK rows are shorter than worsted.
  • Work one row every other day, using the average of the two days, to halve the length.
  • Change the layout. One granny square or hexagon per day (365 motifs), or one stitch per day in a corner-to-corner blanket, gives a blanket of any shape.

Common questions

How many rows is a temperature blanket?
One row per day gives 365 rows, or 366 in a leap year (2028 is the next one). Some makers work two rows per day, one for the high and one for the low, which doubles it to 730.
How long will my temperature blanket be?
It depends on the stitch. In DK garter stitch, 365 rows are about 33 in / 84 cm; in DK single crochet about 73 in / 185 cm. Tall stitches grow fast: worsted double crochet is about 17 ft long.
My blanket will be too long. What can I do?
Use a shorter stitch (garter, seed, single crochet or grit), a thinner yarn, or work one row every two days. Or change the layout: one granny square or hexagon per day, or one stitch per day in a corner-to-corner blanket.
How wide should a temperature blanket be?
Choose the width to suit the length your stitch gives. For a throw, about 45–50 in / 115–125 cm. If your blanket will be longer than about 70 in / 180 cm, go narrower so it doesn’t turn into a runner.
