Crochet Hook Sizes



Before you get started on your free crochet pattern you need to be sure you have the correct crochet hook size. If you start and realize the hook you're using isn't the best, it's never fun to start over. Learning how to read a crochet pattern is half the battle, so be prepared.

Hook sizes can be read using a letter, a number (U.S.) or in measurements such as millimeters (British). However you read it, it's all the same. Some hooks you can use for patterns are made of aluminum, plastic or steel. Medium sized hooks are the easiest to work with if you are a beginner. Below you can find all the hook sizes and conversions you will need to use for your patterns. You might also be interested to learn about crochet symbols and directions chart.
