Crochet Hook Conversion Chart

Crochet Hook ConversionThis Crochet Hook Conversion Chart covers crochet hook sizes for the U.S., U.K. and Canada. The metric sizing is generally what I refer to here in Australia and so I have placed AUS/NZ in the metric hook size column.

In each country, crochet hooks can differ in size and that is why there is a need for this crochet hook conversion chart.

Also take note that the size of crochet hooks can vary from different manufacturers so when you come across a crochet hook conversion chart use it only as a guide and not as gospel.

Customer Review by F. Tronchin:

These ergonomic crochet hooks are great. Even as a relatively young crocheter without the problems of arthritis or carpal-tunnel, my hands hurt from time to time if I’ve been crocheting a lot.

These hooks keep your fingers in a more neutral position which is healthier for your hands.

After using one for a few minutes, you’ll realize that you’re not gripping the hook too tightly and that your hand is relaxed. I think this would be great for crocheters who tend to work too tightly.
