Inquiries about the number of stitches needed to make an Afghan are common among the many of us who crochet with varying tensions. Each crocheter’s afghan sizing and personal tensions are different, thus this solution is tailored to each individual.

Using the data you provide, this calculator will take your crochet tension into account. It doesn’t matter if your blanket is square or rectangular if you use this granny square calculator.

I’ve included standard sizes of blankets and afghans without the extra length to drape over the edges of beds for your convenience.

Before you Calculate Your Squares

I can help you with your calculations if you complete the first step.

  1. To begin, make a single Granny Square by crocheting.
  2. Take a measurement of the square’s width and jot down the result. To the nearest millimeter, round to the nearest tenth of an inch.
  3. Write down the square’s length in millimeters. To the nearest millimeter, round to the nearest tenth of an inch.

Ready to Calculate

You’ll be asked how many inches you want your afghan to be while using the calculator. From the widest to the longest possible perspective. To the nearest millimeter, round to the nearest tenth of an inch.

The calculator will next ask for the results of your measurements.

What our Calculator is Doing

Using the calculator, you can see how many squares you need to make the afghan of your dreams. To acquire the closest width and length measurements, the number of squares is taken into account. After that, it calculates the total number of squares required to finish it.

This is the number of squares you’ll need to finish. A new calculation can be generated by altering the sizes.


The value of one’s time cannot be overstated. You may be amazed at how many less squares you need to finish if you add a few extra rounds. You’ll save time if you don’t have to stop and start squares as often.

Add a few more rounds and recalculate before making a final selection.

Why Is It Called A Granny Square?

Afghanistan, a Pashtun ethnic group, is a common name for a granny square blanket. The country’s textiles and carpets are known for their vibrant colors and unusual designs.

Scraps of yarn that had been unraveled from old clothing were saved by women in the early United States in 1946. Crocheting yarn into little squares was done when there was a lot of it.

In the end, they had a lovely blanket made from the squares they had collected. The “granny” square refers to the fact that older women and grandmothers were typically responsible for this chore.

How Many Rounds Is A Granny Square?

Rounds range from four to five in a traditional granny-square blanket. But don’t worry, we don’t have any size restrictions. You may crochet tiny squares of two rounds, or a giant square blanket, with this technique!

It’s entirely up to you! Let your imagination run wild.

Variations Of Granny Square Blankets

There are a variety of shapes and sizes of granny squares. For those who don’t like the traditional sharp corners, there are different options.

Crochet ring/magic ring

When crocheting round patches, you can use a magic ring to create a firmly closed center. It may appear difficult, but it’s actually quite simple.

When crocheting, you need to use the same technique as you would for other projects. Pull the circle closed after you’ve stitched it all the way around. Tada! Your magic circle is in place!

Multi-color squares

Crochet is a great medium for expressing your individuality and expressing yourself creatively. You can use whatever combination of colors you choose.

It’s possible to tie a different color of yarn onto the end of your finished granny stitch. Work your way around it gradually until you’ve created a lovely design.

It’s fun to learn how to make a granny stitch blanket in a variety of methods. When crocheting, there are a few extra considerations to keep in mind. Let’s see what happens!

How Many Skeins Of Yarn Do You Need For A Granny Square?

Complex patterns and color schemes are common in Afghanistan. If you want to make them, you’ll need quite a bit of yarn.

For a full-sized blanket, you will need between 13 and 18 skeins of yarn. The more colors you mix, the more skeins you’ll need.

You may just need ten skeins if you use fewer colors. Everything is up to you and your design, as well as the amount of effort you’re willing to put into it.

Some things to mind when deciding how much yarn to buy for your project.

Factors to determine yarn amount

Yarn weight

The fewer skeins you require, the heavier the yarn. More is required for a thinner thread.

Blended acrylic yarn is the finest option for making a blanket. Cotton is the yarn of choice if you’re making a washcloth or a coaster.

Item size

Yarn is unnecessary for clothing. Consider stocking up on thread in advance of beginning your blanket-making endeavors.

Stitch type

The amount of yarn required for each stitch varies. As compared to a single crochet, granny stitches use more yarn.

Crochet hook size

The shape of your crochet hook might alter the finished product. You may need more yarn if you use larger hooks because the stitches will be further apart.

A 5mm crochet hook is ideal for making granny squares in the granny square stitch. However, everything is subject to change based on the content of your discussion. Make use of a larger hook if the stitches are too tight.

Tension and gauge

Your stitches will have more space between them when your design requires less tension.

How Many Days Will It Take To Make The Blanket?

Ultimately, it’s up to you and how much time you’re willing to put into the project. It can take anywhere from a few days to a week to make a huge blanket.

You’ll spend less time if you use a smaller blanket. If you’re just getting started, don’t allow the pressure get to you. Let your imagination run wild and come up with a lovely pattern that you’ll cherish.

Crochet the first round by chaining three and working two double crochets into the first stitch. Then, work three dc clusters into the same stitch. To begin, work a sl st into the top of the first ch. At the end of this round, you will have four dc clusters and four ch 1 spaces.

ch 1 and sl st into first stitch of second round. Row 2: Ch 2, 2 dc in same ch 1 space. Each ch 1 stitch is placed in its own ch 1 slot. Cluster of dc, ch 1, cluster of dc in the following ch 1 space around. Sl st the first ch 2 together. You should have 8 dc clusters and 4 ch 1 spaces at the end of this round.

This is the third and last round of crocheting. Row 2: Ch 2, 2 dc in same ch 1 space. Each ch 1 stitch is placed in its own ch 1 slot. On the previous round, Dc clustered in between the clusters. A dc cluster, ch 1, dc cluster in the following ch 1 space. * Dc into the gap between the groups of preceding rows* around. Repeat from * to *. Sl st the first ch 2 together. When you finish this round, you should be left with just 12 cluster stitches and four spaces for ch 1s.

You will continue in the same manner for the rest of the rounds of this granny square design.

Two double crochet clusters in each corner, with a single crochet in between, are what you’ll be working on.

One double crochet cluster will be placed in each gap created by the previous round.

Weave in the ends of your first color when it’s time to switch to the next. Any of the ch 1 spaces will work as a place to join your second color. You’ll then repeat the same process with the following shade of paint.

To make the blanket pictured above, follow these steps:

  • Washed Teal for six rounds
  • Paper White, two rounds each
  • Slate Gray, twice.
  • Washed Teal for two rounds.
  • Paper White, two rounds each
  • Slate Gray, twice.
  • Washed Teal for two rounds.

Granny Square Border Pattern

Work 3 hdc into each corner stitch of the blanket in Round 1. Weave the ends of the yarn together.

Round 2: A picot edging will now be worked. With a slip stitch, join white yarn in a round of sc, ch 3, hdc in the first chain. So, I tinker with the stitches between the picots to ensure that each corner has one. Previously, I’d get so worked up when I realized that once the blanket was finished, you wouldn’t even notice!

How Do I Make a Granny Square Blanket?

It is possible to make granny square blankets in one of two ways.

You begin by working a huge square in rounds until you get the desired size. A border is added at this point, and you have a lovely blanket. As you can see, there is a repeating pattern here.

If you like, you can create a mosaic of individual squares and sew them together. After that, you’d add some form of edging to your blanket.

Beautiful blankets can be made using either method, but the first takes less time.

How Do I Make A Granny Square Blanket Larger?

If you continue crocheting one double crochet cluster between the clusters from the preceding row and *a double crochet cluster, a chain 1* into each corner gap, your blanket might go on forever.

That’s probably not something you want to do.

Between the sizes of 18′′ and 36′′, baby blankets are available. The decision is yours!

What Is the Best Yarn for a Granny Blanket?

Any type of yarn can be used for this project! Knitters who prefer a thick, fluffy blanket should opt for bulky or chunky weight yarn instead of DK or worsted.

A cotton or cotton-blend yarn is ideal for the warmer months. Use something a little cozier while it’s cold outside. Both a soft acrylic and a wool-blend yarn work well for this project.

What Size Hook Should I Use for a Granny Square Blanket?

My crochet is on the tighter side, therefore I prefer to use a hook one size larger than the yarn label recommends. This results in a luxuriously plush blanket with excellent drape.

Crochet in the size specified on the package, unless you know exactly how tight your stitches are going to be.

How Much Yarn Will I Need for a Granny Square Blanket?

Depending on the size of your blanket, you’ll need anywhere from 800 to 1500 yards of worsted-weight yarn to make a granny square baby blanket. It goes without saying that as the blanket grows, so does the amount of yarn required.

I used two skeins of washed teal and one skein of the other colors to make the blanket pictured.

Granny Square Variations

Granny squares can be made in a plethora of different ways. In some cases, the center is a heart; in others, it’s a bouquet. Here are a handful of my personal favorites.

  • Granny Square with Daisy in the Center
  • Granny’s Heart Shaped like a Square
  • Granny Square in Sunburst
  • Heart Shaped Granny’s
  • Monkey Granny Squares in Crochet.

How Long Does It Take to Make a Granny Square?

To construct a large granny square blanket, you’ll need between six and eight hours.
