Blade width, and tooth geometry will determine the cut characteristics.

Here’s a quick rundown to cover most tasks:

For cutting tight curves (less than 5⁄8 ” radius) and delicate, thin materials, use a 1⁄8 ” or 3⁄16 ” 10–14-tpi standard-tooth blade.

To cut curves greater than 5⁄8 ” radius, or when cut quality matters more than speed, use a 1⁄4 ” 6-tpi standard- or skip-tooth blade.

For general ripping and crosscutting, use a 1⁄2” 3-tpi standard- or hook-tooth blade.

For resawing, use the widest 3-tpi skip- or variable-tooth blade your saw accepts. Typically, the wider the blade, the straighter it cuts.

Cutting green (undried) wood requires the widest 2–3-tpi skip-tooth blade your saw accepts.
 Dense, abrasive exotic wood species cut best with a carbide-tooth blade. It will stay sharp longer than a steel or bi-metal blade.

That is the general description for which blade. BUT there are people who resaw using a 3/8” blade. They have to saw much slower than someone using a wider blade, but usually get a smoother finish. Heat kills the cutting edge, and much less heat is generated by a 1” wide skip tooth blade and a low tooth count per inch, than a thinner blade, with a higher tooth count. So using a thinner blade to resaw with, will give a shorter life.

Sometimes a resaw blade will also be carbide tipped, though the majority of bandsaw blades are HSS. More so than with a Table saw blade the lower cost of a HSS blade may offset the generally much higher cost of one with carbide teeth. A case can be easily made that the teeth of the carbide toothed blade will last much longer, but some people shy from them after having the much higher priced bands break, long before the teeth become dull.

The question to ask you is, what bandsaw are you using?? A lot of the decision of which blade for what chore is driven by the saw in question. Some also will be how often will you resaw, versus curve cut?
