Share this Article:
TwitterFacebookPinterestPrint

One of the essential tools to create anything with crochet is, of course, your crochet hook. Understanding crochet hook sizes is an important skill to obtain however, this can be a little confusing because different countries have different names for each size of hook. You will need to know where your crochet pattern originated in order to know which size hook is required.

Crochet Hook Sizes Tutorial

The diameter of the shaft of the hook determines the crochet hook sizes.

  • UK/Australia - If your hook size is in millimeters, it can range from 2mm to 35 mm. If you are using a UK or Canadian hook, or a really vintage hook from Gran’s old work-basket, these are also labeled with numbers, but not the same numbers as the mm size numbers!
  • US - If you are using a USA hook, they are labeled with letters and numbers.

Crochet Hook vs Crochet Needles

Technically crochet uses hooks and knitting uses needles however these terms are often used interchangeably. Knitting needles have a long shaft with no hook on the end while crochet needles or hooks have a hook at the end to grab the yarn with.

Crochet Hook Sizes Conversion Chart

To help make this easier, here is a table, showing various sizes of hooks and their equivalents. It is important to note that there can be some variation in the sizing names used between crochet hook manufacturers, particularly in the larger sizes. For convenience, many manufacturers list both metric sizes and letter sizing on their labels.

Steel Crochet Hook Sizes

Just to complicate things even further, the very fine crochet hooks, also known as steel hooks, thread hooks, or lace hooks have their own system of sizing. Steel hooks come in sizes with numbers that get smaller as the diameter gets larger.

How to Know What Sizes of Crochet Hook to Choose?

The right size crochet hook you choose will determine the size of your stitches.

  • SMALL - A Smaller hook creates tighter finished items and a more solid fabric because the gaps between the loops will be smaller.
  • LARGE - A Larger hook will create a loose weave type fabric with larger holes between the stitches.

Yarn Weights and Crochet Hook Sizes

The type of yarn or crochet threads you select will also affect the fabric you create. Below is a yarn weight chart with recommended crochet hook sizes. Once again these can vary with manufacturers so check the label.

Guidelines for the suitable crochet hook size for a particular yarn are usually printed on the yarn label or band which is wrapped around your yarn ball or skein. These are meant as guidelines only and are affected by your personal preference. Check what size your pattern calls for as it may be designed with a particular density in mind. For example, if you want a very loose, lacy look, you can use a large crochet hook with a thin, lightweight yarn or cotton. In the photo below, the label recommends 4 mm-sized hooks.

Crochet Hook Sizes - FAQS

Best Crochet Hook Sizes for Beginners

If you are just starting to learn how to crochet, try a mid-weight yarn such as worsted (Size 3 or 4 light-medium). This will match with an H8 or 5mm hook which is easy to use and find in craft stores. Further down this article, discusses the different types of hooks but if you are a beginner, then choose aluminum. They are light, cheap and the yarn tends to slide along them easier.

Most Commonly Used Crochet Hook Sizes

Like my recommendation for beginners, the most commonly used crochet hook size tends to be the H8 or 5mm size. It is popular as it pairs with light to medium yarns that are suitable for blankets, scarves, and many clothing items.

Do you Need 1 or 2 Crochet Hooks?

This is a common question asked by beginner crocheters. Unlike knitting where 2 needles are used, crochet only needs one hook.

What Happens if I Crochet with a Bigger Hook?

If you crochet with bigger crochet hook sizes it just means your work will be looser with larger holes. There are actually times when you may choose to crochet with a larger hook. Especially if you tend to crochet tightly, it may be necessary to use a larger hook in order to get the correct gauge.

Can I use Any Size Crochet Hook?

While technically, yes, you can use any crochet hook sizes, you may not get the results you desire. As a rule, thinner yarn means you should use a smaller hook. Try to choose a hook in a couple of sizes of the yarn you are using. If you purchase a kit of different-sized hooks you will always have something suitable at hand.

Does Using a Bigger Crochet Hook Size Use More Yarn?

For the same crochet pattern, switching to a larger hook will definitely use more yarn since your work will be looser with more holes. Conversely, a smaller hook will use less yarn.

Sizes of Crochet Hooks vs Gauge

When you are following a crochet pattern, there will almost always be a section on ‘Gauge’.

What is Crochet Guage?

Guage refers to the number of stitches and rows per inch on your crochet work. It is usually given as a measurement per 4” (10 cm) square. It is a measure of how big your stitches are. Everyone crochets differently. Some people make larger, looser loops and some make smaller, tighter loops.

So even if you are using the same size crochet hook and yarn as your best friend, your garment could end up way smaller or larger than theirs!

For this reason, when following a pattern, it is very important to check your gauge before starting on the actual garment. A LOT of people see this as an unnecessary delay, which prevents them from starting the interesting process of making the actual garment. I have to confess, that I was one of these people when I first started crocheting, but I learned my lesson the hard way!!

It really is worthwhile taking the time to do this, as you want your work to be the correct size, and you want to have the correct amount of yarn for your project. If you crochet fewer stitches per inch than the gauge of the pattern you may run out of yarn, and your garment will be too big. If you crochet more stitches per inch, you will have leftover yarn and your garment will be too small.

Your final project will also look and feel different from the original pattern if your gauge is incorrect.

How To Measure Gauge Swatch

To measure the gauge you will need to crochet a ‘swatch’. This is a small square of crochet fabric, made using the stitch you will be using for your garment or accessory.

Using the crochet hook sizes and yarn thickness suggested in the pattern, chain a number of stitches that will give you a width longer than 4” (10cm). Work up your swatch, using the stitches needed for your pattern until you have made a nice square of crochet, which must also be longer than the 4” (10cm). You can also purchase gauge tools to help you measure.

Now measure the stitches and rows of your swatch. Place your ruler or tape measure horizontally along the stitches, preferably in a central position. Count how many stitches are within your 4” (10cm). Then place the tape measure vertically along your swatch and count how many rows fit into the 4” (10cm) measurement. If you have managed to crochet to gauge, you can now continue to your main project.

How To Correct Gauge with Crochet Hook Sizes

  • If you have more stitches than needed per 4”(10cm), your finished item will be too small. You should try using a larger crochet hook.
  • If you have fewer stitches than needed, your crochet is too loose and your item will be too large. You must change to a smaller crochet hook.

If changing the size of your hook still doesn’t work, try using a crochet hook made from a different material. For example, you may find that you get a different tension with a plastic hook rather than with an aluminum one.

Types Of Crochet Hooks (Crochet Needles)

Aside from different crochet hook sizes, the hooks can be made of different materials.

Types of Crochet HooksPin
Types of Crochet Hooks

Plastic Crochet Hooks

Plastic hooks are the most economical and are very lightweight. They have a very slight texture to them, so your stitches won't slip too easily. They are also perfect for airplane trips!

Metal or Aluminium Crochet Hooks

Hooks are most often made of aluminum for the larger hooks and steel for the very fine hooks. They are very smooth and slippery and the yarn slides easily when using them. Aluminum hooks are generally cheap and so are popular with beginners. When using larger crochet hook sizes, these are easy to use since they are light and easy to grip.

Wooden Crochet Hooks

Wooden crochet hooks can be expensive, but are smooth and have a little bit of texture to stop the yarn from slipping. Collectors can order hand-made, bespoke wooden hooks with beautifully carved handles.

Bamboo Crochet Hooks

Bamboo hooks are very similar to wooden hooks but lighter, and less expensive. The hook part tends to be more pointed than aluminum hooks which I find easier to grip the yarn to pull it through.

Ivory or Bone Crochet Hooks

Ivory or bone hooks are hand-carved and are usually antiques. You can order bone ones to be custom-made if this is what you like to work with however ivory is banned in most countries.

Ergonomic Hooks

These hooks have a shaft usually made of metal, which is the correct measurement for the crochet hook sizes, and then a thicker base or handle. The handles can be made of plastic, rubber, or wood. If you have arthritis, carpal tunnel syndrome, or any hand or wrist condition which makes it uncomfortable or painful to hold a thin hook, these will be the best type for you. Even if you have no problems, some people just prefer the feel of these hooks.

Tunisian Crochet Hooks

Tunisian hooks are very long and thick. They are also called Afghan hooks. Tunisian crochet is different from normal crochet in that it is almost like a mixture between knitting and crochet. You have many more stitches on the hook than with conventional crochet, hence the need for an extra-long hook.

Broomstick Lace Crochet Hooks

Broomstick lace hooks are exceptionally thick (just like a broomstick!) and they are used to create large loops or eyelets in your crochet work, which gives a lacy effect.

How To Hold Your Crochet Hook for Beginners

There is no hard and fast rule about how to hold your hook. You should hold it in any way that is comfortable for you, and that allows you to easily create the loops which form your stitches. There are two common ways of holding the hook:

Pencil Grip

You hold the hook in your dominant hand just as you would hold a pencil to write. The hook part should be facing you, and you grip the shaft between thumb and forefinger, with the other fingers supporting it underneath.

Knife Grip

You hold the hook in your dominant hand with your thumb and middle finger gripping the shaft while your forefinger rests along the top as if holding a knife.

How to Hold Your Yarn

More important than the way you hold the hook, is the way you hold the yarn. You must keep the yarn at a constant tension all the time. It must be steady and tight.

Wrap the yarn around the little finger of your non-dominant hand, then raise your middle finger and lift the yarn with it to keep the tension fairly tight. Use your index finger and thumb to hold the work. Some crocheters prefer to use their forefinger as the tension holder.
