F Hook Crochet Patterns

F is the smallest hook size in our list of top crochet hook sizes, but they go all the way to B in reality. "Smallest" means that you're getting tighter and more stitches in a chain.
On our conversion chart, F is the USA size, the UK size conversion is 8, and the metric is 4.00. These crochet patterns can be anything from shawls to a crochet cozy.
Besides the patterns below, find more F crochet hook patterns here.
G Hook Crochet Patterns

The G hook is a very common crochet hook size for many of our patterns. On our conversion chart, G is the USA size, the UK size conversion is 7, and the metric is 4.50.
You can find crochet patterns that make everything from sweaters and cardigans to baby hats and blankets.

The H hook hugs the middle of the spectrum of crochet hook sizes. Like G, it's extremely common to find crochet patterns that use the size H crochet hook.
On our conversion chart, H is the USA size, the UK size conversion is 6, and the metric is 5.00. From crochet afghans and washcloths to applique, you can find a lot of neat crochet patterns for this hook.

J Hook Crochet Patterns

The J hook is less common and usually used for bulkier yarn or more open crochet patterns. Nice and warm results.
On our conversion chart, J is the USA size, the UK size conversion is 4, and the metric is 6.00, which is why you may also hear it referred to as a size 6 crochet hook. Many cozy blanket patterns are made with this crochet hook size among other things!

K is the biggest crochet hook size on our list and much less commonly used than the rest of the hook sizes. You'll use either a bulkier yarn weight or you'll have a more open weave in your crochet patterns with the K hook.
On our conversion chart, K is the USA size, the UK size conversion is 2, and the metric is 7.00. You'll find scarves made with this hook as well as other crochet patterns.

The crochet hook size chart has a lot of useful info for me especially to see how American sizes differ from UK sizes. I think the best crochet hook to use for any particular project is the hook that is shown on the label of the yarn you are using and not determined by project. The yarn manufacturers recommendation usually is the best way to go.

This is a wonderful book. I am going to try to get all my crochet friends to down load it. I am trying to teach them to crochet but this is even better, they can get an idea of what hooks are best for different projects and they can reference back to it.
