How Many Granny Squares Do You Need?

Each one of us crochets 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 the 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 you Calculate Your Squares

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

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

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.Β 

You will then enter your measurements into the calculator.

What our Calculator is Doing

The calculator is processing your square sizes and cross comparing to the size of the 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.


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

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

    Mikey, aka Michael Sellick, of The Crochet Crowd, started this online journey back in 2008. A mere hobby in trying to reach out to others as he was mentally struggling with his own issues. His goal was simple, find others in the yarn communities, like him, that have a common interest.

    The journey and main baby of the whole idea started with a YouTube Channel and then in 2011, an official website was developed. Michael is not only the face of The Crochet Crowd but also the working engine behind the crowd in self-taught programming, social media and so much more.

    Enjoy the stitching journey. Life is short, enjoy this wonderful hobby and all of the learning opportunities that come with it.

    1. The calculator is missing. I am doing a baby blanket out of farmhouse granny squares. The squares are measuring 4 in x4 in. I would like the blanket to be 42 inches squared if possible. Im using Mandala baby by lion brand color wishing well, 150g, 590 yd. I have 2 skeins. How many squares will I need?

        Thank you… We are reprogramming the site this week. It’s the calculator is most likely turned off during this coding reset. I’ll check into it.

      2. Mikey says:

      I have used this site before and now I cannot see the calculator. My squares are 9 x 9. My afgan needs to be 45. X 55. How many squares do I need?

      1. Mikey says:

        I just checked the programming and it seems to be working on this end. I cannot duplicate the result of it not showing up. Let me plug in your details and see what comes up.

      2. Mikey says:

        Your afghan needs to be 5 squares wide by 6 squares long. You will need 30 squares in total.

      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!

      1. Marina King says:

        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)

        1. Lynnette says:

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

          [CP_CALCULATED_FIELDS id=”11β€³]

        2. Mikey says:

          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.
