In your hands, you’re holding the pattern that you’ve been wanting to try for ages. It’s for an elaborate cowl, that you know your daughter will absolutely adore. You check the pattern for the amount of yarn you’ll need and…. Nothing. Or maybe, the yarn information is there, but you want to use a recycled yarn as opposed to wool, because your daughter is passionate about sustainably focused fashion.
So… now what? How much yarn will you actually need to make this cowl?
This is a problem many crocheters face, whether it be due to fiber substitutions, inadequate pattern details, tightness of stitch, etc. Take the guessing out of your next project with this Yarn Calculation guide, which will help you complete your next project while minimizing scraps.
To help ease the headache you may get from trying to figure out yarn weight, hook size, gauge, etc., we created a handy Yarn Weight Cheat Sheet:
(Please note that your exact yardage and gauge may vary, but this is a great estimate!)
Let’s walk through this with our Classic Fiber Bowl Pattern and our Washi Ribbon Yarn. Say the base of the bowl is complete, but you want to switch colors for the sides? Do you have enough yarn for 10 rows? Let’s find out!
Our Washi Ribbon Yarn has a weight of 5, so it is considered Bulky.
Based on the chart above, and the pattern recommendations, we will be using a size 10.5 U.S./K or 6.5 mm hook
Continuing along with on the chart, there will be 2.75 inches used per single crochet stitch
Tip: If you want the exact inches per stitch, or if you are using a stitch other than single crochet, make a test square, about 10 stitches wide, and 10 rows high. Then, rip out (or “frog”) the last row of the test square, and measure (using a measuring tape or ruler) the amount of yarn it took to make those 10 stitches. Take this number and divide it by 10 to determine how much yarn it took to make 1 stitch.
Once the base is complete, each row of the bowl has 48 stitches. So, 48 stitches x 10 rows = 480 total stitches
In order to calculate the total inches of yarn you'll need, we'll do the following:
Number of stitches x Number of inches per stitch = Total Inches of yarn
For this bowl, we will take...
480 stitches (Step 4) x 2.75" (Step 3) = 1,320" used for 10 Rows
Finally, a simple conversion will help us determine the yardage!
Total Inches of Yarn / 36 = Total Yardage Needed
So, 1,320" (Step 5) / 36 = 36.7 Yards
There you have it! An easy, step-by-step guide for calculating yarn yardage.
