Full blanket yarn requirements
A full (double) mattress is 54 × 75 inches; a blanket with a comfortable drop is about 80 × 90 inches (203 × 229 cm). That is 7,200 square inches — 2.4 times a throw.
Plan on roughly 5,400 yards of worsted in stockinette, 6,850 yards in double crochet and 8,600 yards in single crochet. Bulky yarn reduces that to about 4,050–5,150 yards, and super bulky to 2,700–3,400 yards.
At this size the weight of the finished blanket matters too: a full-size worsted blanket can weigh 2.5–3.5 kg (6–8 lb). Lighter fibers such as acrylic or a wool-acrylic blend, and openwork stitches like granny or shells, keep it comfortable.

About these numbers: estimates assume typical gauge for each yarn weight. Your tension, hook or needle size and stitch pattern can move them by ±15% or more — weigh a swatch in the swatch calculator for a figure based on your own work.
Tips
- Full blanket: about 80 × 90 in (203 × 229 cm)
- Worsted: 5,400–8,600 yd depending on stitch
- Openwork stitches use less yarn and weigh less
- Check the finished weight in the result
How to work out how much yarn you need
- Choose the project. Pick knit or crochet, the project and its size — or a custom width and length.
- Set the yarn. Choose the yarn weight (CYC 0–7) and stitch, then type the length and grams from your skein label.
- Add a safety margin. Keep 10% extra, or more for tight tension, borders and fringe.
- Check with a swatch. For the most accurate number, weigh a blocked swatch in the From a swatch tab and scale it to your project.
