Ever wonder how big your C2C blanket will be? Well… me too! So I came up with a calculation for that… 😉 People ask me all the time “how big will my C2C blanket be?” The **c2c blanket size calculator** will help you figure out the size of your C2C blanket, squares, or scarfs.

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 to make a swatch, then do some math (ugggg).

With this c2c blanket size calculator, you will make 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 C2C blanket size 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!) 😬.

## C2C Blanket Size Calculator

**Google Chrome Users: **

It’s come to my attention that the calculator is not showing up in google chrome. I am working on a solution with the plugin I use – in the meantime, if you download Firefox or Internet Explorer, they show the calculator fine. I apologize for the inconvenience. Hopefully the issue is fixed now

## 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. The C2C blanket size calculator will determine the approximate size of your afghan.

## 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 the 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 in size just using a different hook size, this will make a difference in how big your finished project will be.

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!

## 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!

## Standard blanket sizes:

Blanket Type | Width | Height |
---|---|---|

Receiving Blanket | 40″ | 40″ |

Security Blanket | 14″ | 17″ |

Stroller | 30″ | 35″ |

Toddler | 42″ | 52″ |

Crib | 45″ | 60″ |

Swaddle | 47″ | 47″ |

Throws | 52″ | 60″ |

Super Queen | 96″ | 94″ |

Twin | 66″ | 90 |

Double/Full | 80″ | 90″ |

Queen | 90″ | 90″ |

King | 108″ | 90-100″ |

California King | 110″ | 98″ |

I hope you enjoy this calculator, please share and pin it!

I totally feel dumb. Thank you for your hard work. I appreciate the information

I can’t see the calculator. Google Chrome on a Mac.

Thanks for letting me know. I’m having trouble seeing it on my Firefox too. Let me make sure the plug-in is up-to-date.

Plugin needed updating and it’s fixed now! (I hope) lol. Thanks so much for letting me know!

There is no sliders nor links to sliders to find the calculator. Opened the site in Firefox and Chrome. Is there a direct link to the calculator?

Opened this page in IE and can now see the sliders/calculator. You might want to work with your website coder to ensure this will work in other browsers : )

Seems I’m having trouble with those browsers, need to fix it.

Plugin needed updating and it’s fixed now! (I hope) lol. Thanks so much for letting me know!

Where is the calculator I don’t see one at the bottom of the page as it instructs.ThanksFiona

It’s there. I’m not sure what you are not seeing. Are you on a mobile phone?

Hi, I no longer see it either – macOS on Chrome, in an incognito window.

Plugin needed updating and it’s fixed now! (I hope) lol. Thanks so much for letting me know!

I don’t see it either. I’m using Firefox on Linux. I’ll check it on my windows machine a little later with other browsers.

I checked on my Windows PC with both Firefox and Microsoft Edge. I do not see a link to the calculator. Just trying to help out 🙂

Plugin needed updating and it’s fixed now! (I hope) lol. Thanks so much for letting me know!

At what point do you add on the square to make it rectangular? I am 3 skeins in, can I still do it?

You start the corner for the rectangle when you have the desired width of the blanket you are creating. Then you continue stitching the rectangle until you have the desired length on the longest side.Hope this helps.

In creating a corner to corner pattern, how do I figure out how muchyarn to buy 🤦🏼♀️

Hi 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!

I am sorry that I am just now seeing this. That is a good question! There is a yarn calculator on Joy of Motion Crochet’s blog. She has some really awesome calculators. Here is the link: https://joyofmotioncrochet.com/yarn-yardage-calculator-based-on-stitch-length-for-knitters-and-crocheters/
