Crochet C2C Yarn Weight Calculator

Have you ever wanted to make a C2C blanket, but don't know if you have enough yarn to make the size you want? Well, I've had the same dilemma and so have put together this quick calculator to give you the number of rows and approximate total weight of yarn you will need based on a small sampler.

Step 1: Make your sampler
Start by working a small square of C2C in the yarn and hook of choice. Be honest, you've probably got some spare yarn of the same type in your stash and an array of hooks, so it won't be a problem. Make sure it's a complete square (increase followed by decrease rows) and make a note of how many rows you make. The larger the sampler the more accurate the results. I worked 9 rows (5 increase rows and 4 decrease rows).

Step 2: Weigh your sampler
Once you have made your sample you will need to weigh it. The calculator uses grams as this gives a finer measure of weight. Clearly, the larger the sample, the more accurate the weight will be, as most home scales are not particularly sensitive. You may just about be able to see my sampler weighed 3 grams.

Step 3: Measure your sampler
Now measure how wide your sampler is. As it's a simple C2C it should be square! Lay the tape measure across it and smooth down lightly. You can see that my sampler was approximately 2.75" wide. If I wanted to get a more accurate measure of both weight and width I would have made a larger sampler. But I'm only after approximate values, so I know how many balls of yarn to add to my stash!

Step 4: Enter your specifications
You will be asked to specify some dimensions ...

• How wide you want your final blanket to be. (I want a 36" blanket)
• How wide your sampler is. (Mine is 2.75")
• How many rows you made (I made 9 rows)
• How much your sampler weighs. (Mine was 3 grams)
  Make sure you click out of the weight box to see the total weight change.
  

The calculator will tell you how many increase rows, decrease rows, number of rows in total, approximate total yarn weight needed and the final size of the blanket. If you try out my specifications you'll see I need to make 131 rows (66 increase rows and 65 decrease rows) and will need approximately 523 g of yarn. I'll be getting 6 x 100 g balls just to make sure!

NOTE: The final size may not be the same as the size you specified you wanted. However, it will be the nearest to that size based on your yarn, hook and tension taken from your sampler. If you want an exact size, change the hook or tension until you get the desired size. In reality, a blanket is not an exact science, so as long as it's within an inch or two, I'm normally happy. :)
