10 Amazing Granny Square Cardigan Patterns For A Modern Look

This is a great collection of modern granny square cardigan patterns for you to enjoy. Choose from these great patterns for a modern outfit.


Granny square is such an iconic crochet make. They are versatile little makes that open the doors to so many possibilities.

The great thing is, that even if you make a single granny square, you can still make it into something useful.

You can fold it into a small envelope style bag and use it as a gift card holder or a small money wallet.

You can also make a huge pile of all different colorful granny squares and make a stunning blanket for your home.

Easy to choose matching colors and customise the finished size, granny square blankets are always a winner.

What if I told you that if you can crochet a granny square, you can definitely crochet a cardigan? You don’t believe me?

I have compiled 10 amazing granny square cardigan patterns into this collection so you don’t have to go hunting for the perfect pattern.

How many granny squares do I need to make a cardigan?

There are many factors that we need to think about in order to answer this question. Secondly, it is very subjective too.

Here are a few things to take into account:

Finished width of the cardigan

Firstly, if you are on the adventurous journey of crocheting your very own granny square cardigan, you firstly need to decide what the finished width will be.

You can simply get your chest measurement measured around the widest point of your bust.

Then add a few inches to this measurement for a positive ease. Usually this can be anything between two to four inches. This is totally up to you and the way you want your cardigan to fit you.

Finished length of the cardigan

Secondly, you need to decide what length of the cardigan you are looking for. Would you like your cardigan to be cropped to your waist?

Or would you prefer longer versions that go down to your hips? Or even better a long duster style cardigan?

The total length will definitely affect the amount of granny squares you will need to finish your cardigan.

Size of the individual granny square

Thirdly, you need to find a granny square pattern you would like to use for your granny square cardigan. This could be just a classic granny square.

Or you can go fancy and find a granny square that you really like with a few different stitches and motifs.

Then make a sample granny square and measure it.

Once you have all your measurements, you can work out how many granny squares you would need to match your chest circumference.

Then work out how many granny squares you would need to create the length of the cardigan you want to make.

You can then simply multiply the number of squares for width times the number of squares required for length and you have the amount of squares needed for your granny square cardigan main body.

The last thing is to work out the width and length of your sleeves and follow the same principle as for main body. Do not forget to double the amounts of squares for sleeves as you will need to make 2 sleeves.

How many balls of wool do I need for a granny square cardigan?

Once you have worked out the total number of granny squares you will need to complete your cardigan, this step becomes quite easy.

All you need to do is work out the amount of yarn you have used for your sample granny square.

You can do this by weighing the square on your kitchen scales.

Then simply multiply the weight of one square by the total amount of squares you need to complete your cardigan.

I would strongly advise to always get an extra ball of yarn to avoid running out of yarn and having to hunt down one extra ball.

How do you attach sleeves to a granny square cardigan?

Attaching sleeves to your granny square cardigan can be just as easy as attaching any crochet fabric together.

The great thing is that you will be attaching two sides of granny squares together. This means that you can crochet through one stitch on each granny square to crochet them together.

Because you will be attaching them “stitch to stitch”, you will achieve neat results.

Alternatively, you can also use a yarn needle and a piece of yarn in the same color and sew the sleeves onto your cardigan.

Again if you do this stitch to stitch, you will achieve neat results and finish to your cardigan.

How many squares do I need for a patchwork cardigan?

Patchwork crochet cardigan uses a very similar technique as granny square cardigan.

However, instead crocheting granny squares in joined rounds, you can crochet your squares separately in plain and simple rows.

These could be squares that use single or plain double crochet stitches which are super easy to work.

Firstly, you need to decide on the type of stitch you would like to use and the finished size of the squares you will be making.

Once you have decided, you can follow exactly the same procedure for working out how many squares you will need as you would have for the granny square cardigan.
