How do you figure out afghan sizes?
I have created a formula to calculate 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.
For my calculator, you will need 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 with accurate details.

hi Mike, It would be a great help if you could you tell me how many skeins yarn I would need for a baby blanket 36x36.The yarn I'm using is 297 yds per 100 gms..

Hi! I'm making the Zig Zag Baby Blanket which measures 32 by 60 and needs 6 Caron Simply Soft. I want to change the size of it to 69 by 90. How many Caron Simply Soft will I need? Thank you.

Sorry, I don't know the answer to that unless I do it myself and figure it out. Unfortunately, I am short of time to make this afghan to give you this information. There's no magic formula of afghan size changes to get the yarn needed for difference sizes.

The original size is 32 X 60 = 1,920 sq inches. If it calls for 6 skeins, then you're able to crochet 1,920/6 = 320 sq inches of blanket per 1 skein. But the size you want is 69 X 90 = 6,210 sq inches. So 6,210/320 = 19 skeins needed. Who says we don't use math in "real life"?

This is a pretty good tool. There is a problem with it though. When figuring the width for the starting chain, it does not take into account how many stitches you need for a set. It wants to be exactly the width you choose.
So for example the pattern I'm using is in sets of 14, my 4" chain is 12 chains or 3 chains per inch. to make a blanket that's 39" wide I need 117 chains according to the calculator. However my pattern will be cut off because 14 stitches*8 pattern repeats=112 chains which is 37 1/3" wide or 14 stitches*9 pattern repeats=126 chains which is 42" wide.
The tool isn't perfect but it helped me figure out that I need to either make 8 or 9 repeats in my pattern for what I'm making. I'm sure the row height will be pretty spot on but I can always measure it to double check.
