Have you ever been in a position where you needed or wanted to know how many yards of yarn your finished project used, but have no idea how to calculate yardage of a finished project?
If you are a pattern tester or are interested in pattern testing; the question of how many yards of yarn did you use will most likely be asked.
Nope, you do not need to frog your project and measure with a yard stick!
Finding the yardage by using a basic mathematical equation is really simple and quick to do. You probably even remember it!
I do not like mathing, never have, probably never will. This is so easy though, if I can do it…I know you can too!!
Who knew we’d actually have a need to cross-multiply and divide?!?!
Need to calculate the yardage left in a partial skein?! Found how here: How To Calculate Yardage of a Partial Skein
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 Finished Project
Here’s a fun ‘lil pict-o-gram (is that a word?) because math is always more fun when it’s pretty!!
Here is a PDF Download for you too!
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 finished project
This is where we need our scale. Place your finished project on the scale and record what the weight is; remember to use the same unit of measurement as you did for the skein weight!
My project weighed 46 grams. So I will put this number in that box.
Here’s what my project sheet looks like now:
And, now we math…
Here’s where we 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:
46 x 364 = 16744
Next we want to divide that number by the bottom right number :
16744/ 198 = 84.56
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 finished project, easily!
