Crochet Hook Sizes and Size Chart

Crochet hook sizes refer to the size of the hook used to create crocheted items. Different sizes of crochet hooks are used for different thicknesses of yarn, and the size of the hook can affect the finished size and drape of the crocheted item.

The size of a crochet hook is typically indicated by a letter or number, with larger sizes having larger numbers or letters. The most common crochet hook sizes range from B-1 (2.25 mm) to T-30 (30 mm), with each size having a specific range of yarn weights.

For the remainder of this article, I will cover the basics of crochet hooks, what sizes they come in, and the various crochet hooks types.

What Is a Crochet Hook?

A crochet hook is a tool used to create crocheted fabrics. It consists of a thin shaft with a hook or a latch at one end, which is used to pull yarn or thread through loops of fabric. Crochet hooks come in a variety of sizes and materials, which can affect the finished size and drape of the crocheted item.

The anatomy of a crochet hook consists of the following parts:

• Shaft: The shaft is the long, thin part of the crochet hook that is used to create the loops of fabric. It is usually made of metal, plastic, wood, or bamboo.
• Hook or latch: The hook or latch is the curved or angled end of the crochet hook that is used to pull the yarn or thread through the loops of fabric.
• Throat: The throat is the area of the hook that narrows as it approaches the latch. It is used to hold the yarn in place as it is pulled through the loops.
• Handle: The handle is the part of the crochet hook that is held in the hand while crocheting. It is typically wider and more comfortable to grip than the shaft.
• Point: The point is the very tip of the crochet hook, located at the opposite end of the latch. It is used to poke through the loops of fabric in order to create new stitches.
• Size indicator: Crochet hooks are usually labeled with a size indicator, such as a letter or number, which indicates the size of the hook. The size of the crochet hook can affect the finished size and drape of the crocheted item.

To use a crochet hook, you first need to create a foundation chain, which is a series of loops created using the crochet hook. You then work additional stitches into the foundation chain or into previous rows of stitches to build up the fabric. There are many different types of crochet stitches that can be used to create a wide variety of fabrics and patterns.

Crochet hooks can be used to create a wide range of items, including clothing, accessories, home decor items, and more. They are a popular choice for those who enjoy crafting and are often used in conjunction with other tools, such as knitting needles and looms, to create a variety of different textiles.

Overview of Crochet Hook Sizes

Crochet hook sizes refer to the size of the hook used to create crocheted items. Different sizes of crochet hooks are used for different thicknesses of yarn, and the size of the hook can affect the finished size and drape of the crocheted item.

The size of a crochet hook will be expressed in a letter and/or a number. The larger the number or letter, the larger the hook. The most common crochet hook sizes range from B-1 to T-30 (2.25 to 30 mm). Each size describes a specific yarn weight range.

It is important to choose the appropriate size crochet hook for your project in order to achieve the desired result. In general, smaller crochet hook sizes are used for fine yarns and threads, while larger sizes are used for thicker yarns. The recommended crochet hook size for a particular yarn can usually be found on the yarn label or in a crochet pattern.

In addition to standard crochet hook sizes, there are also specialty hooks available for specific techniques or yarn types, such as Tunisian crochet hooks and hooks for working with thicker or multicolored yarns.

Crochet hook sizes are expressed differently based on where you’re located. Here, I’ll describe the different crochet hook sizes. The figures listed below follow the standards set by the Craft Yarn Council.

Types of Crochet Hooks

There are 2 ways to categorize crochet hook types—by hook styles and by material. I’ll cover both of these categories down below.

Hook Styles

There are 5 main types of hook styles to choose from, which are:

• Inline hooks: Inline hooks have a shaft that is straight and parallel to the latch, which allows for a more consistent gauge and a smoother finish on the crocheted fabric.
• Tapered hooks: Tapered hooks have a shaft that gradually narrows towards the latch, which allows for a more comfortable grip and easier insertion into the fabric.
• Throatless hooks: Throatless hooks have a latch that extends all the way to the end of the shaft without a throat to hold the yarn in place. This allows for more flexibility and versatility in the crocheting process.
• Tunisian crochet hooks: Tunisian crochet hooks have a long, straight shaft with a latch at one end and a stopper at the other. They are used for a specific type of crochet called Tunisian crochet, which involves creating a fabric with a combination of knitting and crocheting techniques.
• Ergonomic hooks: Ergonomic crochet hooks are designed with a comfortable grip and a shape that helps reduce hand fatigue during prolonged crocheting sessions. They may have a handle that is contoured to fit the hand more comfortably, or they may have a thicker or more cushioned grip to reduce pressure on the hand.

Hook Material

A crochet hook will typically be made of one of the following materials:

• Metal: Metal crochet hooks are usually made from aluminum, steel, or brass. They are strong, durable, and have a smooth finish, which can help prevent snagging of the yarn. However, they can be cold to the touch and may be slippery, which can make them harder to grip for some crocheters.
• Plastic: Plastic crochet hooks are lightweight, affordable, and easy to grip. They are a good choice for beginners, but they may not be as durable as metal or wooden hooks and may not glide through the fabric as smoothly.
• Wood: Wood crochet hooks are smooth and warm to the touch, which can make them more comfortable to use for some crocheters. They are also strong and durable, but they may be more expensive than metal or plastic hooks.
• Bamboo: Bamboo crochet hooks are made from bamboo, a sustainable and renewable resource. They are smooth, lightweight, and comfortable to hold but may not be as strong as wood or metal hooks.
