How do I figure out how much yarn I need?
Formula: (length x width x gauge) / 6 = yards needed. Length and width are in inches and gauge is in stitches per inch. For example, if you’d like a scarf 48″ long and 8″ wide using a worsted weight yarn, (48 x 8 x 5) / 6 = 320 yards. Round up as running out of yarn is the worst!
How much yarn do I need for a queen size blanket?
Queen Size Blanket (Afghan)
To crochet a queen size blanket or afghan, you will need about 10 to 18 skeins of yarn. This means that the total amount of yardage used would be around 2000-4000 yards if using only one color and up to 8000+ yards when multiple colors are involved.
