Afghan Size Calculator

Mikey Afghan Size Calculator
How to figure out your sizing for your afghan.

Afghan Sizing Customized For You

How to do you figure out afghan sizes? I have created a formula to help you achieve the chain counts needed to get to the sizes you need. The formula will also calculate stitch sets for those who require a pattern, such as a wave afghan to stay in balance for stitches.

Sizes of afghans have been provided in the equation for those interested to know the standard sizes of crochet afghans. I have included everything from receiving blanket sizes to king size. I have included the drape and non-drape of the afghans for those who are looking for that.

For my calculator, you will need to a measuring tape to give me a few dimensions. Due to everyone having their own gauge for stitching, this formula will adjust to your own tension to provide you accurate details.

    I thought this calculator was amazing, but when I tried to return a few days later(because I’m OCD and wanted to double check my measurements) the calculator section of the article was missing. Was it removed for some reason? I’m using the same browser I was using last time.

    Wonderful tool, thank you! When entering the decimal amount for 3 rows (.75), the next box calculates rows per inch @ .25, which is the height of one row. Rows per inch should be 4? Doesn’t matter, the total rows needed to complete the project is accurate.

    Ok, question. I read a pattern that was originally for knitters, but someone gives a general outline of how to do the same pattern for crochet. They said to chain enough to length to make 70 inches. Is there a calculation for that? As in how many sc in an inch? or how many sc in 70 inches?

    Or do I just single crochet and keep measuring the length till I get to to 70 inches on a measuring tape? Kind of wondering if I am overthinking this!? Help!

    This is a great tool, thank you so much! On the section that calculates the length based on your row height, I’m finding an error when you try to enter a number with a decimal. For example, I’m trying to enter 2.25, but a yellow bubble pops up saying “Please enter only digits.” Despite the error, it does appear that it’s calculating correctly – still, it seems like something that should be fixed or clarified. Thanks again!

      We have a help desk but are so overwhelmed by it. There are so many questions of people asking us to do searching and other items where people can invest a little time of Google and find the resources. We find by the time we get back to someone, they already found their answer. It’s easy to email for help than it is to do some time investment of their own. Only so much we can do.

    I think the math in the calculator is off… I told it that my pattern repeat is in units of 24 stitches +2 to turn, and it somehow spit out an odd number of starting chains. An even number plus an even number is even. An even number times any number is still even.

            There is a space under “Crochet a 6″ Chain. Now only measure the middle portion of the chain with a distance of 4″ and tell me how many chains are in that 4″ section.” for you to type your answer into then you select the width ans it will tell you how many chains. There is also a space under “If you are working on sets of stitches to acheive your width. Here is your chain count with the added extra chains.” for you type in your answer and another space under “Measuring the height of 3 rows only. What is that height in decimal format. Example 3/4″ = 0.75, 1″ = 1, 1 1/4″ = 1.25” and then you select your desired length and it tells you how many rows per inch and how many rows you need to complete your afghan. It is not set up like a traditional looking calculator and the spaces are very light so they blend into the page but they are there.

    Love that you took such time and thought in providing this calculator! Would you be able to do a tutorial on how to figure out the multiples of a stitch pattern if the pattern does not specify this information? With that info it would be easy to alter about any pattern to come up with a proper size for any pattern. Thanks so much Mikey!

      Either your tension is getting tighter as you crochet or you are missing stitches as you go along. Make sure to keep counting and don’t forget to make a stitch in the last stitch in each row. HTH,

      Sounds like you may be loosing stitches. One trick I use is to put a marker at the first stitch of each row… ( A long piece of contrasting yarn works great – and just move it up under the loops of the first stitch each row).
      This way I am sure I am going all the way to the end of the row

    Hello Mikey, I totally love this yarn calculator as I’m a dummy when it comes to math and I totally love your videos I have learned alot from them, you are a great teacher. My question is this: I want to crochet a chevron king size blanket, I have figured out I’d need 211 ch. across 76″ width and 160 rows 80″ length. I don’t know how to find out how many skeins of yarn I’d need I’m using red heart 4 med. and I’m planning on using size ‘N’ 9.0 hook. Please help me figure this out and thank you in advance.

      Terry, I’ve done a couple C2C afghans, and I believe Mikey states it in the video… But once you reach a width you want…. You just don’t add onto that side anymore….and continue all the rest until you reach th length you wanted. If that makes any sense…

    love this!!! for those who are freaked my Math, let me break it down to steps…there’s only 10. As an example let’s say were making a baby blanket 36 inch square, ok , here we go..Step 1- ch 6 inches, now what are the number(#) of chains(ch) in 4 inches(“), in my example there are 20. Step 2- if the is a pattern calls for repeats or has multiples or sets in the project ,what is that number… in my example there are 8. Step 3- Number of chains(ch) at end of row for turning …in my example 2 ch. Step 4- making a baby blanket= 36 inches …so 20 ch (from step 1)= 4 inches and the blanket is 36 in , so 4 inches X ? = 36 the answer is 9. Step 5- total number of chains needed for width 20 ch X 9 = 80 ch. Step 6- add turning ch…80 ch width + 2 ch= 82 ch total for the width. Step 7- Now for the height with the swatch made up 4 rows, measure how tall 3 rows are … in my example 3 rows = 2 inches. Step 8 – the baby blanket is 36 inches. Step 9- find out the number of rows per inch…in my example we take 2 inches (step 7) divided by 3(for 3 rows = .6667 height per row. Step 10 ow take the height you need in the project , in my project , the baby blanket is 36 inches now divide by the decimal you got in Step 9 36/ .6667 = 53.97 or 54 rows height.

    Do you have or know of any resources that can teach me how to create my own patterns? I am confused on if it matters how much you chain. Do the chains need to be even and then you add 2 or 3 depending on the stitch you are using?

    Mikey! Thanks for creating this calculator! It makes crocheting almost foolproof. It’s SO NICE that for ANY size blanket I can determine just how long to make my foundation row (i.e. how many chains I should start with). To create any size blanket, ALL I HAVE TO DO is crochet a swatch, as per your instructions above. I just plug the numbers into the appropriate boxes and ¡Voila! It gives me the number of chains to start with and the number of rows needed to finish it! My 3rd grader has just learned to crochet and she loves your calculator too!! 😉

      12 sc =4″ so divide 12 by 4 getting 3. So for every inch it takes 3sc. 6 inches would be 18sc.
      The rows are harder since 15 divided by 4 does not come out even. 15 divided by 4 is 3.75 so every 3.75 rows would be an inch. 3.75 times 6 equals 22.5 rows. This is the math, but don’t know how to do the 22.5 rows. 😉
