Gauge. The word that can strike fear into the hearts of many crocheters. But have no fear, my fellow yarn enthusiasts, I’m here to demystify this tricky concept and make it easy to understand.
Whether you’re familiar with gauge or have never heard of it before, I’ll break it down for you and show you how you can get the perfect fitting/sized crochet projects every time.
So, let’s unravel the mystery of gauge together, shall we?
Gauge is a sum of three things…
YOU, YOUR HOOK AND YARN

What is gauge and why is it important
Gauge is all about how tight or loose you’re holding your yarn and how big or small your stitches are.
This might not sound like the most exciting thing, but trust me, it’s super important for making sure your crochet projects turn out just the way you want them to!
When it comes to gauge, there are two types to keep in mind: yarn label gauge and pattern gauge. Yarn label gauge gives you a general idea of how many stitches and rows are needed to make a 4″ x 4″ swatch, while pattern gauge is the specific gauge that needs to be met for your finished item to be the same size as indicated in the crochet pattern you’re following.
To make sure your project turns out perfectly, you’ll need to make a small sample piece called a “gauge swatch” (more on that later) and measure it to see if it’s the correct size.
If it’s not, don’t worry, you can adjust your hook size and/or yarn and make another gauge swatch until it’s just right. (More on that later too!)
It might seem a bit confusing and daunting at first, but with a little practice, you’ll be a gauge pro in no time!
Now that you have a basic understanding of gauge, let’s keep going and learn a bit more.

Factors that affect gauge
Did you know that there are a bunch of things that can affect your gauge? Yeap, it’s true!
The type of yarn, the way you hold the yarn, the type of hook, your tension, and even how long you’ve been crocheting can all play a role. But don’t worry, you can make sure your project turns out just the way you want it to by making a gauge swatch before you start.
What is a gauge swatch
A gauge swatch is It’s a small piece of crocheted fabric used to measure the tension of the yarn with the hook you’re using in your project. It’s usually made using the same stitch pattern and hook size as written in the crochet pattern.
However, if the stitch can only be competed by working in the round (working in circles) you may find the gauge has been worked using only single crochet assuming that once the gauge is met for that stitch the gauge for the crochet pattern will be met as well.
When working on a crochet project, making a gauge swatch is one of the most important steps in determining if the finished project will have the desired dimensions and drape. It’s especially important for beginners making their first project. But don’t worry, seasoned crocheters start to know if they are a tight or loose crocheter and also get used to their favourite crochet designers and if their tensions are tight or loose, and don’t always find it necessary to make a swatch to check gauge.
I know, it might seem like a waste of time, but trust me, it’s worth it. I remember when I first started crocheting, I ignored gauge and the first hat I ever made for myself fit my then nine month old baby, and then when I tried to make a baby hat, it fit my husband.
It took me a long time to realize how important gauge was in my crochet journey, I tried to avoid it, I tried to ignore it, but in the end I had to learn to embrace it. And, now that I think about it, making all those hats that didn’t fit anyone was both a waste of time and money so hopefully you will embrace making a gauge swatch quicker than I did.
Think of it as making little dishcloths, use them, gift them, and what ever you do make those those swatches! Just think of it as not only checking your gauge, but also making something useful in the process. And remember, if you only do one thing… MAKE YOUR SWATCH!

Understanding Yarn Label Gauge and Crochet Pattern Gauge
Have you ever wondered about the difference between yarn label gauge and crochet pattern gauge? You may have confusion between gauge found on a yarn label and the gauge written in a crochet pattern. Finding a yarn with a gauge close to the pattern is a great starting point but there is more to it than that.
It’s important to understand the difference because it ensures that your finished project will have the desired dimensions and drape.
Let’s go over the difference between the two types of gauge, how they are used together, and how to use them to achieve the correct gauge for your project.

What is Yarn Label Gauge
Yarn label gauge is the gauge found on the yarn label, it’s a set of measurements provided by the yarn manufacturer that gives you an idea of how many stitches and rows can be crocheted with a certain yarn and hook size.
This gauge is usually provided in a 4-inch by 4-inch (10cm x 10cm) swatch and is a general guideline for the yarn.

It’s important to note that the yarn label gauge is a recommended gauge and not a requirement.
I rarely use the recommended hook size on the yarn but play with different sizes of hooks to get the exact look and feel I want my crochet design to have.
What is Crochet Pattern Gauge
Crochet pattern gauge, on the other hand, is the specific gauge required for a specific pattern. It is usually provided in the form of a specific number of stitches and rows in a specific measurement, such as 16 stitches and 20 rows in 4 inches of single crochet using a size H/8 (5mm) hook. The pattern gauge is the gauge that the designer has tested and can guarantee if met, that the finished project will have the correct and expected dimensions and drape.
How are Crochet and Yarn Gauge Used Together
Yarn label gauge and crochet pattern gauge are used together to ensure that the finished project will look feel and fit exactly as expected. To achieve the correct gauge for your project, you will need to make a gauge swatch using the yarn and hook size specified in the pattern and compare it to the pattern gauge.
If the gauge swatch is not the same as the pattern gauge, you will need to make adjustments.
The best place to start is adjusting your hook size. Usually going up or down a hook size will bring you inline with the pattern gauge. Be sure to double check by making another swatch.
It is also important to note that yarns can be substituted, in this case you need to make sure that the yarn you are substituting has similar properties to the one suggested in the pattern and make a gauge swatch with the yarn you want to use and compare it to the gauge mentioned in the pattern. Look for a substitute yarn that has a yarn gauge close to the one recommended in the pattern.
Your Tension – You ain’t broke don’t fix it!
Your crochet tension is unique to you, and although you may try to change it, as you get further into your project you will most likely slip back into your own way of crocheting and the gauge will change back to what is comfortable for you.
For those of you who are just starting out, don’t be surprised if you find that your gauge is a bit tight at first. As you get used to making the stitches, your gauge may loosen up and that’s completely normal. The more you crochet, the more consistent your gauge will become. So don’t worry, with time and practice, you’ll get the hang of it.
How to read a pattern gauge
Get ready to get technical. This is an example of a gauge you may come across in your crochet pattern.
Take a look, and pay attention, because this little snippet of information can make a huge difference in the final outcome of your project!
Examples of how you might find gauge written
Depending on the designer or item being made you might find the crochet gauge written a few different ways. Let’s take a gauge of 4″ x 4″ = 16 sc and 20 rows, this is how I write my gauges most often.
You might also find it written these ways.
- Stitches per inch (SPI) or rows per inch (RPI) so 4SPI and 5RPI = 4″ X 4″
- Stitches and rows per a certain measurement: for example “16 stitches and 20 rows = 4 inches in single crochet”
- Number of stitches and rows in a specific measurement, for example: “16 stitches x 20 rows in 4 x 4 inches using a certain stitch pattern”
- A ratio of stitches to rows, for example: “16 stitches to 20 rows in 4 inches (10 cm)”
- Or visual representation, for example: a picture of a gauge swatch with measurements and stitch count indicated.
No matter how pattern gauge is written the most important detail is how many stitches per inch and how many rows per inch.
These all mean that in a 4-inch by 4-inch square, there should be 16 stitches and 20 rows when using single crochet stitch with the recommended yarn and hook size.
So now that you know what your gauge should be – what now?
You need to make a gauge swatch using the recommended hook size and yarn, using single crochet stitch. Here is how.

How to Make a Gauge Swatch
To make a gauge swatch, follow these steps:
- Find the stitch pattern and hook size specified in the pattern in the area marked ‘gauge’. For example, a pattern may call for a gauge of 16 stitches and 20 rows in a 4 inch x 4 inch square of single crochet using a size H/8 (5mm) hook.
- To start your swatch chain 16 stitches (plus a few extra stitches usually 4-6 extra) using the specified hook size.
- Work the specified number of rows in the stitch pattern, being sure to turn the work at the end of each row. If you are just beginning to crochet make sure to use a stitch marker so you do not add or miss stitches. You want to make sure that the number stitches in every row are the same.
- Measure the gauge swatch to see if it is the correct size. In the example above, the gauge swatch should measure 4 inches wide and 4 inches tall.
Measure your gauge swatch, and if it measures 4 inches by 4 inches with 16 stitches and 20 rows, then your gauge is correct and you are ready to move on with the pattern.
When measuring your gauge swatch, make sure to use a ruler or a gauge measurement tool. These tools are available in craft stores and online and can help you get an accurate measurement. Once you have these measurements, you can compare them to the desired measurements specified in the pattern.

But what if my crochet swatch isn’t the right size?
Creating your masterpiece is all about getting the details just right, and that includes your gauge. Keep in mind that your gauge can be influenced by a variety of factors such as the yarn you’re using, how you hold your yarn and your unique tension.
You will have one of three outcomes, your swatch will be the same size, it may be smaller or it may be bigger.
For example, if the gauge swatch should measure 4 inches wide and 4 inches tall, but your finished swatch measures 3 inches by 3 inches this means that the gauge is too tight. The finished item will be smaller than desired. In this case, THE FIRST STEP is to try a larger crochet hook which will make a larger/looser stitch and you may be able to achieve the correct gauge.
If the opposite is so and your swatch is larger say, 5 inches by 5 inches then your tension is too loose and you may need to go down a hook size to meet the correct gauge.
If your gauge is not correct, changing your hook size with caution. Remember the designer picked that hook size for a reason so don’t be hasty when trying a larger or smaller hook. Start by using a hook that is only .5mm larger or .5mm smaller.
If you still need to make changes to your gauge you can consider using a different yarn. Again don’t use a drastically different sized yarn. Little changes add up to big changes in the size and feel of your projects.

How to Calculate your Stitches Per Inch
The easiest way to do this is by using my Crochet Gauge Calculator below. BUT if you like to really know how the magic happens keep reading the steps below to learn how to calculate on your own.
Here’s a step-by-step guide on how to calculate your stitches per inch when making a 4 inches by 4 inches crochet swatch.
- Begin by crocheting a swatch (see instructions above) that is 4 inches by 4 inches. Make sure to use the same yarn and hook size that you plan to use for your project.
- Once your swatch is complete, count the number of stitches across the width of the swatch.
- Divide the number of stitches by 4 to calculate the number of stitches per inch. For example, if you have 20 stitches across the width of the swatch, your stitches per inch would be 20/4 = 5 stitches per inch.
- Next, count the number of rows across the length of the swatch.
- Divide the number of rows by 4 to calculate the number of rows per inch. For example, if you have 30 rows across the length of the swatch, your rows per inch would be 30/4 = 7.5 rows per inch.
- Your stitches per inch and rows per inch will give you a clear picture of your gauge and will help you adjust your tension if necessary.

So what do the numbers mean?
If you have less stitches per inch than the pattern calls for your tension/gauge is too loose you need to make it smaller.
If you have more stitches per inch than the pattern calls for your tension/gauge is too tight and you need to make it larger.
Remember that even the slightest tension change can affect the final size of your project, so it’s essential to make a gauge swatch before starting your project to ensure your piece turns out just as you envisioned it.
Time saving tip! BEFORE you make too many rows measure and count your number of stitches across. If the number is close to the number in the pattern gauge keep going. If not stop change your hook and start again.
FAQ About Crochet Gauge
