How To Calculate Yardage of Partial Skein

Sharing is caring!

If you’re like me when you go to your yarn stash to pick some pretties to start a new project you are face-to-face with an assortment of partially used skeins. This inevitably leads to the questions “is this enough yarn?” I don’t know about you but yarn chicken is not my favorite game to play! To prevent the unknown, you can easily calculate the yardage of a partial skein!

Need find out the yardage of a finished project?! Find out how here: How to Calculate the Yardage of a Finished Project

It may seem like a lot of mathing but a quick calculation is all it takes!

Let’s go through it step-by-step.

What You’ll Need

To be able to use this method you will need a few things:

  • Kitchen scale (I recommend a digital one!) I use this *Starfrit One!
  • The label from the yarn you used. (TIP- if you know what yarn it is but no longer have the label google the brand/type for the info needed!)
  • Your completed project.

Calculate Yardage of a Partial Skein

Since math can be dull, I’ve made this pretty printable to help spice it up!

Let’s work through the worksheet together

Each box will give you directions of what number goes where.

Top Right – Yardage of the full skein used

I like to start here, but you don’t have to. You can fill the green and pink boxes in any order.

Here’s is where you want to check your label for the TOTAL YARDAGE of the skein you’ve used.

For my example I will use Red Heart Super Saver solids.

The total yardage of RHSS solids is 364 yards, so I will put that number in that box.

Bottom Right – Weight of full skein used

You can choose grams or ounces for this one, just be consistent and be sure to use the same one throughout!! I use grams.

The total weight of RHSS soilds is 198 grams, so I will put this number in that box.

Bottom Left – Weight of your partial skein

This is where we need our scale. Place your partial skein on the scale and record what the weight is; remember to use the same unit of measurement as you did for the full skein weight!

My partial skein weighed 74 grams. So I will put this number in that box.

Here’s what my project sheet looks like now:

And, now we math…

Now we will cross multiple and divide. I know, not nearly as fun as filling in the pretty boxes!

So, we want to find the X, and by X I mean the ?.

Take the bottom left number and multiply by the top right number:

74 x 364 = 26936

Next we want to divide that number by the bottom right number :

26936/ 198 = 136.04

Now, we put that final number in the top left box – That’s the number of yards your project used! I like to round up just to be on the safe side.

There You Go!

Now you can calculate the yardage of your partial skein, easily!

Want to get some practice in?!

Take a peek my available patterns HERE and go pick out some stashed yarn and see if you have enough!
