Ever wonder how big your C2C blanket will be? Me too! So I came up with a calculation for that… 😉

We’ve all been there… the graph is 80 x 90 ~ 200 x 300 ~ 25 x 25 – but how BIG will that be?

The best way to figure it out is make a swatch, then do some math (ugggg).

With this calculator, you’ll still be making a swatch (but only a small one!) and I did the math for you (thank you Algebra 1B).

This C2C blanket size calculator is a simple way to figure that out based on ** your** personal gauge, yarn, and hook size. I created this calculator to help ease the pain of breaking out the calculator every time, so please – bookmark the page and come back any time you’re in need!

This calculator is great because no matter how tight or how loose you crochet – using the sliders will tell you exactly how big your blanket will be. Then you can make hook size or yarn adjustments – or even try to change your tension to get the size blanket you want.

The calculator is below – Read the instructions before you get all excited and skip down to the calculator (like something I would do!) 😬.

### How to use this calculator

All you need to do is make a small swatch at least 4 C2C stitches wide, but you can make a larger swatch if you want.

### Step 1

Get your hook and yarn, make a swatch in C2C until you have 4 squares wide and 4 squares tall (or 6 wide and 6 tall) Measure width from beginning of block 1 to the end of block 4. How wide is it? Use the slider to find the measurement you need. These measurements are in inches, but will convert to centimeters below for metric users.

Write down that number and repeat it for the height of your blanket.

Here is an example of 2 partial swatches.

In the swatch on the left, I used a 4mm hook, and **Lion Brands 24/7 Cotton.** In the swatch on the right, I used a 6mm hook, and **Lion Brands 24/7 Cotton.** You can see the difference is size just using a different hook size, this will make a difference in how big your finished project will be.

### Step 2

Use the second slider below to enter the number blocks in your graph. You can use the same sliders below to determine the height your blanket will be!

### Do you like to make your own graphs?

Once you complete your swatch in your chosen yarn and hook size, measure the 4 squares. Use the slider to find your width in inches. Then move the other slider around until you reach the blanket width/height you want, and that’s how many squares you’ll need in your graph to achieve the size blanket you want. Repeat for the height and Walla!

I’ve created a tutorial on the basics of C2C below. You’ll learn how to make the C2C (corner to corner) stitch, increase, decrease, changing colors, carrying colors, and how to work a graph that is asymmetrical (i.e. 80 x 90 squares).

May 16, 2019 at 1:49 pmHi Dawn! Well, that’s kind of loaded question because much depends on the hook size and the yarn you will be using, also how large your graph is (squares wide, by squares high). Create a small bit of C2C, like a square 5 x 5 wide and tall. When you reach the end. Mark the yarn as close the end of the last stitch. Then rip out one square and mark the beginning of that square. Measure from mark to mark. That is how much yarn you will have per square. Write that number down or add it to a spreadsheet. You can then guesstimate by either counting the number of squares each color in you graph has (which for larger squares will be quite cumbersome), or you can eye ball it. Take the number of inches in the square, and figure out how many squares you have per yard of yarn. You know what? I may just make a calculator for this! lol. Or, in the meantime, if you’re creating the graph on your own, you can use the online resource called stitchboard: https://stitchboard.com/pages/pattern/freePatternWizard.php, which when you create a graph there, it will tell you how much yarn you need for the project. The only problem with that is if you’re graphing from another source. So, give me a day or two and I’ll make you a calculator. Seems like there is quite a need for it eh? Thanks for the comment!
