How much yarn for a baby blanket
A baby blanket (36 × 36 in / 91 × 91 cm) takes about 1,220 yd of worsted (weight 4) yarn in single crochet, likely between 1,040 yd and 1,470 yd. In double crochet it is about 980 yd, and knit in stockinette about 950 yd.
With 200-yard skeins, buy 8 skeins for single crochet in worsted (enough for the high end). Thicker yarn needs fewer yards; thinner yarn more.

Getting an exact number
Work a swatch in your yarn and stitch, weigh it, and scale up: project area ÷ swatch area × swatch weight gives the grams, and the skein label turns grams into yards. The yarn calculator does this for you.
Buy all the skeins at once from the same dye lot, and plan about 10 % extra for edging, seams and joining.
Estimates from the StitchTick yarn calculator: fabric area × typical yards per square inch for each yarn weight and stitch (Craft Yarn Council wraps per inch). Stitch pattern, hook and tension can change them by 15–20 % either way.

Frequently asked questions
How many skeins for a baby blanket?
In worsted single crochet, plan for up to 1,470 yd: 8 skeins of 200 yards.

How do I work out yarn from a swatch?
Weigh your swatch, divide the project area by the swatch area, and multiply by the swatch weight. Then turn grams into yards with the skein label (for example 100 g = 200 yd).
