Kristin Omdahl’s Guide to Yarn Estimates
Estimating how much yarn will be needed for a project is a topic that I am frequently asked about. As both a crocheter and knitter, this is invaluable information for a variety of reasons, and even as a designer this is really important information for me, too! As always, I am happy to share my knowledge with you!
Why Do I Need to Know About Yarn Estimates?
There are so many reasons you may want to learn about yarn estimates, or at least keep this information handy for when you do! Here are some common reasons:
- yarn shown in pattern is discontinued
- yarn shown in pattern isn’t budget friendly for you
- yarn show in pattern isn’t fiber friendly for you
- yarn shown in pattern doesn’t come in colors you like
- you want to modify the pattern to work with a different weight yarn
- you want to modify the pattern to work with a different fiber content yarn
- you want to create without an existing pattern
What are the Determining Factors for the Yarn Estimate Ranges?
Knitting and crochet require different amounts of yarn, generally speaking. However, types of stitches used and gauge are also important facts to consider. Bobbles, cables and textured stitches require more yardage, lace and open work require less yardage, and simple stitches would be closer to the mid-range (double crochet or stockinette for knitting).
Your own personal gauge is an important factor as well. Are you a tight or loose knitter/crocheter? If you are tight, look at the higher side of the yarn yardage estimate range. And if you are loose, look to the lower end of the yarn yardage estimate range.
How to Use Yarn Estimate Information
Once you know the estimated yarn yardage for your project, here’s how you can use it.
Total yards needed for a pattern ÷ (divided by) yards per ball/hank/skein of your chosen yarn = (equals) the number of balls you’ll need (always round up to the nearest whole number if the math doesn’t work out evenly).
For example, let’s say you estimate you’ll need 900 yds of yarn to make a shawl. The yarn you want to use is sold in balls that are 200 yds per ball.
900 ÷ 200 = 4.5 balls, rounded up to 5 balls
Another common issue: what if a pattern only tells you how many balls of yarn you need, but not the total yardage.
For example, let’s say the pattern calls for 10 balls of yarn. Check the yarn label to determine how many yards are in each ball/hank/skein. In this example, we will say it is 150 yds per ball. You may even need to search online to find out the information about the yarn, if it is not provided in the pattern.
10 ball x (times) 150 yds per ball = (equals) 1500 yds.
Armed with this information, you can now choose a different yarn if you want.
