If you are new to the world of crochet, it is best to start with medium-sized crochet hooks (between 4 and 5 mm) with an ergonomic handle. This type of hook is easier to control and allows you to learn the technique without straining your hands.
In addition, many beginners choose to buy a crochet hook set with comfortable grips, as this gives them the chance to try different sizes and materials until they find the one that best suits their way of holding the hook and the type of yarn they prefer.
