## How Many Granny Squares Do You Need?

Each of us crochet with our tensions and we receive messages asking us how many granny squares people will need to complete their afghans. This answer is unique to each crocheter as the sizing of their afghans and personal tensions can be different.

This calculator will factor in your crochet tension with information that you give me. This granny square calculator will figure out your afghans, regardless if it’s square or rectangle.

For your convenience, I have put in average sizes of blankets/afghans that do not include drape over the edges of mattresses.

## Before your Calculate Your Squares

You need to complete 1 step before you do your calculations so I can figure this out for you.

- Crochet 1 Granny Square.
- Measure the width of the square – Write Down that Number.
*Round to the nearest inch.* - Measure the length of the square – Write down that Number.
**Round to the nearest inch.**

### Ready to Calculate

The calculator will ask you how many inches you want your afghan to be. In both width and length. *Round to the nearest inch. *

You will then enter in your measurements into the calculator.

## What our Calculator is Doing

The calculator is processing your square sizes and cross comparing to the size of afghan you want. It factors in how many squares to get to the closest measurements in both width and length. It then counts the squares needed to fill it all in.

The answer given is how many squares you will need to complete. You can change the sizes and recalculate.

## Tips

Time is precious. You may be pleasantly surprised by adding a few extra rounds on how many less squares you may need to finish. Stopping and starting squares less times will save you time.

You may want to add a few extra rounds and recalculate and make a decision.

Wow, this granny square calculator is brilliant, just realised though that I need to crochet 500 squares for my desired size, never mind only 441 to go, these little squares are keeping me going through this strange period we are all experiencing at the mo. Stay safe and thanks for this ??

Hi! I was so excited to find this resource, but the actual granny square calculator seems to be missing? I’m using an iPhone XS Max, and have tried the site in Safari and Google internet browsers and it’s still not there… Hopefully this can be fixed? Thank you!

If you scroll to the end of the blog it should be there, or are you saying that you did and it’s not showing? It worked for me just now I was playing with it. If you are unable to see it at all at the bottom of the page, send me the info and I will run it through for you. (height x width you want the blanket, and size of your granny square in inches)

I was using the calculator a few days ago, but now it’s missing. All I see is:

Strange… it appears here… Let me circle back and try again in a few hours. If there is an issue, I will turn off this article.

Great resource for beginners! Keeping busy during this worriesom times. It is helping me keeping down the anxiety. Again, this is a great tool. Thanks!

🙂 Granny Squares are the best, there are so many fun things you can do with them, and I really didn’t realize how many different styles there were until I started looking! crochet is the best therapy

Making my first ever granny square blanket, actually trying to make several in time for Christmas. Been making squares, lots of squares lol, but after calculating 4 in squares for a queen, I see I have a whole lot more squares to go, better get to my squares. Does that make me square?

No it makes you fabulous! 😀

Looks like the calculator disappeared? I can’t find it. It used to show up on this page.

Will look into it further. Michael

I found the twin size narrow, but I adjusted the width to what I wanted and it was bang on. Perfect. Looking forward to finishing my first ever granny square afghan. I guarantee you it won’t take me 30 years like it took one of my grandmothers. Lol.

I’m crocheting my first afghan and I was planning to make it for a queen sized bed. WOWZERS, that’s a LOT of 9 x 9 squares!! It may take me 30 years like your grandmother!
