How To Crochet a Large Granny Square (so it stays square)

If you know how to crochet then you likely know how to make a granny square. (If you don’t here’s a tutorial on how to make a granny square.)

I’ve made small squares, medium-sized squares and a large granny square. However, I’ve always had a problem when making a large granny square; the square would end up, well, less than square. Once the square would get to, say bigger than ten rows, it would lean to one side, look crooked and just generally displeasing to this crocheter’s eye. But hurrah! I’ve figured out how to overcome this worrisome predicament.

And I’m pleased to say it’s a pretty simple solution. I’m sure I’m not the first to work it out but that’s no reason not to do a happy dance. I tried the technique on The Hodge Podge blanket. All it took was turning the blanket after each row. Instead of crocheting round and round, I crocheted a round, flipped the blanket over and started another row. You can see below where the “seam” is in the blanket, where I’ve turned it over after each row. Of course if you are making each row in one colour you won’t see the seam. I’m not worried about it on The Hodge Podge, because well, the whole point of The Hodge Podge is not to worry!

There’s an added benefit to turning after each row. There is no “front” or “back” to the blanket.

  1. I love your giant granny squares, they are so colourful. And that is a great tip too – I recently made a granny square with large squares and found the same problem – maybe I’ll try it this way next time!

    So glad To find out I’m not the only one who noticed the square became off kilter after 7 or 8 rows. I just couldn’t continue with an unsquare square but I do just love the afghan it’s so colorful. I do have a question tho — when you say “turn or flip” do you mean like turning the piece as I would if I were doing a plain old dc afghan from the front to the back? I had called Lion Brand because I bought the pattern from them and they advised me to start each new color row in a different corner of the Granny Square — didn’t work. Anxious to start once again. Thanks for your time.

      Hi Gladys,
      Yes, I turn the blanket over and start the new row, just like if you were doing straight rows. I do also try to start the new row in a random spot each time so the “join” isn’t in the same place for every row.
      Good luck!

  3. Yvonne Washington

    Thanks for this info. I’ve had the same problem also. I’m not sure if I’m getting the instructions correct. When you flip the blanket are you fasting off & starting @ a different spot? Would you have a video on this? Thanks much.

    • katieskitchenblog

      Hi Yvonne,

      At first I wasn’t starting in a different spot when I flipped the blanket. You can see this caused a “seam” in the blanket, only because I was using such random scraps rather than a set pattern (eg each row being a separate colour would not show a “seam”)

      Later I decided to start each row in a different place, just to mix up the colours.

      I didn’t find either method to affect the overall straightness of the square. In the scrappy blanket I’m working on at the moment I have decided to start each row in a different place, after flipping the square over.

    what is the best way to join the squares together , just sew them?

  5. Lauren

    I found this blog and am so happy to maybe get some answers! A friend of mine taught me a super simple way to make the afghan however, she does not use a slip stitch to make new rows. And each new row comes together in the corner where I can also change colors. I can’t remember how she did it but there is no slip stich and chaining three for each new row. Can you help?!


  6. Beverley

    My large Granny squares are more like diamonds. They seem to go out too much at the corners, more than in the middle. Any ideas? will flipping it over help?

    • katieskitchenblog

      Hi Beverley,
      Do you mind if I ask which size hook and yarn you are using?

      • Beverley

        5.5 and am using double knit

        • Beverley

          I have actually tried using a 4, 4.5 and 5 an always have the same problem with the corners going out further than the sides. I have tried to fiddle to make it look better by doing less chains on the sides and also less trebles on the corners ie 2, this has not helped. My mother in law has looked and cannot see what I am doing wrong from a stitch perspective.

            I also had a problem with a seemingly uneven large basic granny square. Despite an equal number of stitches on all four sides my blanket was looking like a four legged starfish.
            In my case the corners were the cause of the problem and this is why. While the method I used for the corners was nothing unusual (3tr, 2ch, 3tr), I ended up with too much chain length in the corners to maintain a neat squared shape in relation to the sides.
            This problem was not noticeable when my piece was still small to about 30cm across, but at about 50cm a distortion had become apparent, which I ignored, thinking that blocking would fix the shape once I’d finished.
            When almost finished (120cm) I laid it out on the floor, and half would be nice and flat and the other half had excess no matter which side I’d start from. But when I started flattening from the centre out towards each edge all the excess fell evenly along the diagonals like 4 darts. (No blocking will fix this).
            My solution was to unravel several rows and reduce the corners to (3tr, 1ch, 3tr) to tighten up the corners a bit and improved the overall shape of my blanket.
            Next time I make a similar large project I think I’ll stick with 1ch in all the corners after the first 3 or 4 rows. Also will be tightening that single chain as my crochet style is loose to begin with.

    Lovely blanket.
    I also turn every row and it does work. However my blanket doesn’t appear square as the corners seem to flare out as it grows. I have a consistent tension and I use a the correct hook for the yarn. Is there a solution to this please?

    • Beverley

      I had this problem but it is now solved. I went back to the beginning and bought a book from Dorling Kinersley and followed their very clear pictorial instructions on doing trebles. I do 3 trebles, 1 chain then at corners, three trebles, three chain. It works. I use a size 3.5 hook. hope this helps x

  8. maypole

    Thank you Beverley I will try that

  9. Brodie Bee

    hi im Brodie,
    I had only started crochet about a year ago and now everyone is calling me a pro but Im not quite sure I get this. so just to make sure I have it right all you have to do at the end of the row just flip your large granny square and it will stay as a square.
    please email me back Thanx, Brodie ……

  10. Beth

    Your tip works well. But I have another problem. My large granny square corners are so pointy that the sides pull and as well as buckle. Like I’m building up too much fabric at the corners. Any ideas? Thanks. Beth

  11. Carol ward

    If you do the seam at a corner you cannot see it. Thank you for your tip it is great to do a square that stays a square

  12. Charlotte

    I have recently started crocheting and decided to make a blanket out of a large granny square. I’m about 20 rows in and have noticed the corners curling and the shape going a bit un-square. However, I am reluctant to start again! Do you think if I turn it now and start crocheting from the other side that this will possibly rectify the problem? Thank you

    • katieskitchenblog

      Hi Charlotte,
      I haven’t tired turning it that far in to a blanket! Perhaps it’s worth a try. Blocking the blanket at the end my also help, but I haven’t tried that myself.
      sorry I can’t be of more help, but do let me know how you go!

  13. Anne Sinisalo

    I have seen what you describe above to happen to my square and have been considering also turning the square after each row. Now that I have seen that the rows remain looking nice I guess I have to take my work down and start over. But need to do it when my husband is not ar home. He cannot understand how I can take all down after hours of work.

    • katieskitchenblog

      Hi Anne,
      I understand completely!
      Some people may have success blocking their work when it is done – you could try this.

      • Safiyyah Abdurrahman

        Can you tell me what do you mean by blocking your work?

        • katieskitchenblog

          Hi Safiyyah,
          Blocking is helping your project to be gently pulled into shape when it is finished. There are different ways to do it but often involves making the work damp and pining it onto a soft surface, while gently pulling it straight/into shape. You then leave it to dry.

  14. Anne Marie

    Hi, I did know this, read it on a Facebook group and happily it works! However would you have any idea how I would go about doing the same procedure without changing colour, I am simply knotting leftover yarns together TO USE UP without me buying more as it was Sublime, s bit pricy. I’d really appreciate your advice – and I now have another crochet blog to follow.

  15. Mari

    Tension matters too with granny squares.
    Happy to report I have finally managed to achieve a large granny square without pointiness. Current project at 105cm square and distortion free.
    My crochet technique was at fault and am sooo.. happy to have discovered this. It turns out, that I was not maintaining tension on the yarn at that point when finishing one stitch and starting the next, so the last or top loop of each stitch ended up being pulled out and too loose. This makes the edge of each row grow excessively and the distortion becomes more obvious the bigger the granny gets.
    I have learned to make sure to hold the yarn of that last loop tight around the hook while starting the next stitch and not let those top loops get too loose.
    Previously my grannies had edges of equal length, but were longer than across the width of the square. Now all measurements match without having to tweak the type of stitches like I was thinking of in my comment in Dec 2013.

      Hi Mari,
      Thanks for the update, and so glad you have figured out what needed adjusting!
      Happy crocheting,

  16. Christine

    Hi, simple stitch crocheter here! tried your way and it worked well. Liked the idea of no wrong side. Then I tried keeping the hook as upright as possible. Noticed that the DCs were upright and not leaning to the left. The last DC seems to be longer than the other 2 but doesn’t seem to affect anything. Always thought the hook was to be parallel with the row below but it caused the stitch to lean.I can’t believe how square the blanket turned out and no lines. I make 24 ” doll blankets so I don’t know if as the blanket gets larger if it will continue to be square. Hope so! Might be part of what Mari was saying.

  17. Christine French

    Hi, tried your discovery for squaring blankets, it worked and I like the idea of no wrong side. Then, I tried holding the hook as upright as I could. Had been holding it parallel to the row below and noticed the DCS were leaning left. Now they’re upright with the last DC a bit longer than the other 2. I make 24″ blankets for dolls so I don’t know if it stays square past that. Really surprised that something so simple worked! May be related to what Mari pointed out.

  18. Jaimie

    I just wanted to say thank you. I couldn’t figure out why the granny square was never straight. I love the granny square and really love it now.

  19. S.A.

    I make half double solid grannies; have tried alternating how many stitches I add at the corners every other row. It helps some, but I’m still having problems. I tried reducing to the same number of stitches, but one chain and thought that was working, but the sample square I’m working on looks like it may yet turn into a potato chip. Very frustrating. It’s my favorite kind of blanket to make.

  20. S.A.

    I forgot to mention that I’ve always turned after each row, so that’s never been the issue.

    Is there a way to block a finished Afghan?

    This is what I have been looking for to help with creating nice straight large granny squares. So happy to have found your site. Thanks for the tips and the great pictures of your scrappy granny! 🙂

  25. Hi I found this site very interesting as my granny square is not square. Im new to crochet so will now try and turn it over many thanks.

  26. Hi many thnaks for information on keeping my granny squares straight. I am new to crochet so this site I found is very helpful thank you. carol reynolds.

  27. "SAM"

    I do half double square afghans and have the problem with too much in the corners. I tried reducing the number of stitches every two rows and it helps somewhat. I have noticed my stitches in the corner area are taller and tend to shorten along the sides, which is really the problem. I have tried making my stitches tighter when I do the corners, but it doesn’t always work – and the yarn I usually use is very inconsistent making it even more difficult.

  28. maypole

    I have no trouble keeping the square straight as I turn every row. But the larger it becomes, it begins to flare out, is there a way to prevent this or is it part and parcel of the giant granny square?

  29. Arlene

    I have learned and heard from other crochrt’s that if you do 3 HDC Ch1 3 HDC in the corners that it will even out..

  30. patty

    Hello everyone. I am also doing a never ending granny. i have about 10 rows done ansd the rows are curling. I read about flipping the afghan? does that mean when you get to the corner you crochet in the oposite direction. Im sorry. Im not quitre understanding. Ive never heard the term flipping the afghan before. any hewlp would be appreciate. thank you in advance.

    • katieskitchenblog

      Hi Patty,

      Once you finish around you fasten off your yarn. You then turn the blanket to the back. You pretend that is now the front and join your next piece of yarn. You complete your round as normal, remembering that the “back” is now your front for the current round.
      When you finish that round, repeat the above.


  31. Sharon J Flatekval

    Hello, I am making a never ending granny square blanket. I just want to make sure about the flipping instructions. What I have been doing is just starting the next row in a different corner than from where I last ended. The blanket is very floppy. So do you mean actually turning it over so there is a wrong side and a right side – like the way it would be on straight row crocheting? I thank you for your help.

    • katieskitchenblog

      Hi Sharon,
      It may be floppy if your hook is a little too large for the yarn/your tension.

      After each row I turn the blanket over to the wrong side and begin the next row. So now the wrong side is the right side! At the end of that row I flip again. In the end you will have a blanket with no wrong or right side.
