There are a few things to consider when choosing the right blade for your needs. The type of cutter, the material you're cutting, and the thickness of the material are all important factors.
Type of Cutter: The type of cutter you have will dictate what kind of blade you need. For example, if you have a Cricut machine, available at https://www.firmuz.com/industry/fabric-cutting/, you'll need a Cricut-specific blade.
Material You're Cutting: The type of material you're cutting will also dictate the type of blade you need. For example, if you're cutting paper, you'll need a different blade than if you're cutting vinyl.
The thickness of Material: The thickness of the material you're cutting is also an important factor to consider. If you're cutting something thin like paper, you'll need a different blade than if you're cutting something thick like cardstock.
Flexible vs. Rigid Material: Most blades are designed to cut flexible materials like vinyl, but not tough materials like chipboard. So if you're cutting something tough like chipboard, you'll need a blade that is designed for it.
If all of this talk about types of blades and material thicknesses is confusing, fear not! We have put together an easy-to-read chart below that will help you figure out what type of blade to buy for your machine.
As we said before, the size of the stencil will determine the size of your blade. You can't just look at the blade and know what size it is (unless it's marked with sizes on it). You'll need to check your cutting machine's manual because they will tell you the maximum cutting capacity. For example, on our Cricut machines, we have found that a letter-sized (8.5" x 11") material can be cut using any of the blades.
If your machine has a maximum cutting size of 12", then it will only cut up to 12" materials with one blade. The following chart contains the maximum cutting size for each blade available:
