How to choose the size of zipper teeth?

This passage mainly tells about how to choose the size of the teeth of the zipper.

When you want to choose a suitable zipper, the size of the chain teeth is a very important consideration. So, how do you judge which type of sprocket you need? What are the differences between different sprocket sizes? Let us find out.

When you buy, the size of the sprocket you can choose is about 3mm to 35mm, which refers to the width between the two sides of the sprocket.

First of all, let us look at a normal-sized wallet or small bag. Normally, their zippers are thin and small nylon coil zippers, which is a very typical 3mm size. The standard metal invisible zippers are also the same size. Except for the zippers used to make clothes, the teeth of other zippers are all 3mm in size.

Then, let's think about the standard lightweight jacket with heavy duty zippers for canvas again. When choosing a zipper by the yard for a lightweight jacket, there is a basic rule: In order not to overwhelm the jacket version, choose a lighter zipper instead of large metal zipper. Therefore, the size of the sprocket is usually between 5mm and 6mm, no matter what kind of zipper material, metal, plastic, or coil, this is the most critical condition. If you want to know the size of the zipper teeth, you ought to find the back of the zipper head.

As for outerwear or leather jackets, our brand always recommends heavy-duty zippers. The width of the sprocket is about 7mm to 8mm. This specific size is enough to lock the clothing firmly, but at the same time, it will not break.

Next, if you ought to consider items such as heavier bags with double slide handbag zipper, backpacks with felt zipper pouch, duffel bags, zippers for leather bags and even suitcases, which require larger sprocket sizes. If you observe, you can see that the zipper elements of these items are usually bigger than the zipper elements of the wallet. That is because the designer wants to have both sturdiness and sufficient load-bearing capacity on a zipper. The size of the sprocket is usually from 8mm to 15mm, depending on the item.

When you see this, you might think, would anyone still want a bigger size zipper instead of 5x7 zipper pouch? Yes, the facts will confirm your thoughts. In the fashion industry, the huge chain teeth are very popular with some fashion designers. This is the 35mm zipper. This bigger zipper pouch with strap is both functional and ornamental. Generally speaking, when you consider that the audience of large zippers is limited, they can only be customized, and then they can be purchased.
