Crochet Hooks - How to Choose the Right Type and Size
A crochet hook is a tool consisting of a slender handle with a hook at one (or both) ends, which is used to pull thread or yarn through loops to create crochet stitches. You can also use a crochet hook to create hairpin lace, to pick up dropped knitting stitches, or thread beads onto string. Sizes, handles, and materials that make up crochet hooks can vary. Each type has specific benefits and drawbacks from the ease of use, price, and comfort.
Types of Crochet Hooks
Steel : Steel are for the smallest sizes and are often used in fine thread crochet such as in doilies.
Aluminum: Aluminum are available a large range of sizes. Aluminum hooks allow you to crochet smoothly and quickly.
Plastic : Plastic are available in all the common sizes as well as jumbo hooks. They are very large and are usually made of hollow plastic, because it is lightweight.
Bamboo : Bamboo are lightweight and warm in the hand and are available in all but the smallest and jumbo sizes.
Tunisian : Tunisian are longer than regular hooks, and sometimes have a hook on each end. A crochet hook with a hook on both ends is also called a cro hook. Like a knitting needle, you keep your stitches on a tunisian crochet hook as you create the fabric. Tunisian crochet is also called afghan crochet, and the fabric looks different from normal crochet, and a little like knitting.
Ergonomic : Ergonomic have larger soft handles or handles you can insert a regular hook into. They are designed to reduce the strain in your hands as you grip a small hook for an extended period of time. There are also stress relief gloves that can also help to ease hand soreness or pain.
Knook : Knook is a long crochet hook with a hole running through one end. You thread a piece of yarn through the hole in the knook needle, and you can create stitches that look like knitting, but with a single crochet hook rather than with knitting needles.
Crochet Hook Sizes
- Crochet Hook sizes vary based on the material, brand, and country that the hook was produced in.
- The size of a crochet hook is determined by the diameter of the shaft, or the part of the hook between the point and the handle. The shaft determines how large your stitches will be.
- Steel hooks are also known as “thread hooks” and should only be used for fine lace thread. They come in numbered sizes that get larger as the number gets smaller. The sizes vary from the 0.6 mm thickness of the size 14 to the 3 mm thickness of the size 00.
- Crochet hooks made and sold in the USA use a lettering system for their sizes. As the letter gets further into the alphabet, the hook gets larger. These sizes vary from the 2.25 mm size B to the 16 mm size Q.
How to Choose the Right Size Hook
If you look at the label of any skein of yarn, there will be a suggested hook size listed, and an estimated number of stitches per inch (or 4 inches). Crochet a swatch with the stitch pattern you are going to use for your project, wash your yarn, let is dry, and then measure your stitches. You may need to swatch again with a larger or smaller size hook, depending on if you are a loose or tight needle.
Here is a link to a helpful chart from the Craft Yarn Council which tells you the recommended hook size for each weight of yarn, and an approximate number of stitches per four inches in single crochet.
