Twin blanket yarn requirements
A twin mattress is 39 × 75 inches, so a twin blanket that drapes over the sides is usually around 66 × 90 inches (168 × 229 cm). That is almost twice the area of a throw, and the yarn requirement doubles accordingly.
In worsted weight you will need about 4,450 yards knitted in stockinette or 5,650 yards in double crochet. Single crochet pushes past 7,000 yards. That is a lot of skeins — 23 to 36 standard 200-yard balls — so many makers choose bulky or super bulky yarn for bed-size blankets, or work them in squares or strips that are easier to handle.
If you only want the blanket to cover the top of the mattress (a coverlet or bed runner), measure the mattress and add the drop you want on each side; type those dimensions into the calculator rather than using the default size.

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
- Twin blanket: about 66 × 90 in (168 × 229 cm)

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.
