So, before purchasing crochet hooks for beginners, you need to make sure that the size of the hook matches the threads. Otherwise, during operation, you can prick. However, the most popular size of crochet hook is H/8 5 mm.

How to Know if Your Crochet Hook is Suitable for Knitting With Specific Threads?

Before choosing a hook, it is necessary to know the size of the crochet hook. If the size of the hook does not match the threads, this will affect the quality of the future thing. For example, there will be too tight knitting – if the thread is thick, and the hook is vice versa, or uneven loops, stretching – when knitting with a thick hook with thin threads. 

There are 2 ways:

1st Way – Calculate the length per 100 grams of the thread

Hook diameterThread length per 100 g.  
0.5-1mm1600-2000 m
1-1.5mm600-1500 m  
2-2.5 mm300-500 m  
3-3.5250-350 m  
3-4200 m  
5-6100 m or less

Hooks of a larger diameter are used for loose knitting from woolen and semi-woolen yarns.

2nd Way: Manual selection

If there is no information about threads, select the hook according to the thickness of the thread. It would be best to remember that the hook’s size should be approximately 2–2.5 times larger than the thread’s.

Put the thread in the notch of the hook and pull a little. If the thread completely blocks the hook, then the hook is thin. When knitting with such a crochet, the working thread will delaminate, and the product will be too dense.

The hook is large if the thread entirely lies in the recess and leaves a little space. When knitting with such crochet, the product will turn out loose.

Standard Sizes of Crochet Hook for Practical Application

Depending on the thickness of the thread, the number of hooks is selected. “No” is the thickness of the tool in mm.

Wood is also a light material. The low price allows them to be updated normally.

Made of Aluminum

These hooks are the most affordable. They are very comfortable and do not electrify the yarn. But they still have more disadvantages since aluminum is a very soft material, and its hooks are very flexible.

It is an excellent tool to knit woolen threads, especially thick ones. Because of its fragility, you must be careful when handling this item. Bone hooks are very expensive.

Combined Hooks

These are such hooks, in which many different materials are used. For example, the rod is metal, and the handle is wooden or plastic.

These are comfortable hooks. They fit well in hand. Most importantly, make sure that the rod and handle are fixed and not very small and narrow. Otherwise, there is a possibility that the hook will break quickly.
