Here's a simple calculator for a rough estimate
Determining how much yarn you need for a project is a very common problem we see in our store and with our online customers. You don't want to over buy but you also don't want to run short and not be able to match your dye lot or worse yet, find another skein if it is no longer available.
Fortunately, most knit and crochet patterns include a list of materials, including how many skeins of yarn you will need to complete the project. However, sometimes we have to ask the question, How Much Yarn Do I Need?
These tips for planning your knit and crochet projects will help you figure out the averages of yards needed for each type of popular project like hats, shawls, cowls, sweaters and gloves. We will also go over how to determine how many yards are in a skein of yarn, tips for deciding how much yarn to buy, and free knit and crochet patterns for each type of project.
Because every pattern is different, there are a lot of factors to consider when deciding how much yarn to buy. These suggested numbers of skeins and yards to buy are approximate estimates, but use as much knowledge as you have to determine how much yarn you will need to purchase for your project. On our website we try our best to list the actual yardage for each yarn we sell. On our patterns we try to list the recommended yarn and the number of skeins needed for a typical size associated with the specific pattern.
These are a few of the key things I consider when choosing a yarn and determining how much to buy.
