What Size Bandsaw Do You Need for Resawing?

The short version: size is about cut height and tension

People often ask about bandsaw size as if one number settles it. In practice, three things decide whether a saw can resaw well: how tall a board it can fit under the guides, whether it can tension a wide blade, and whether the motor can keep the blade moving through dense wood.

Wheel diameter (the 12 inch or 14 inch in the saw's name) is a rough guide to all three. Bigger wheels usually mean a taller frame, a sturdier tension system and more room for a wide blade. That is why larger saws tend to be better resaw machines, though a well-tuned 14 inch saw can do a lot.

Match the saw to the boards you plan to cut

Start with your widest board. When you resaw, the board stands on its edge, so the board's width becomes the height of the cut. Your saw's maximum cut height, listed in the manual or on the spec sheet, must be at least that tall.

Next, think about how often you will do it. Slicing a few narrow boards into thinner stock is a very different job from cutting veneer or bookmatched panels all day. Occasional work is forgiving. Frequent work rewards a stronger frame and a bigger motor.

• Measure the widest board you expect to resawn and compare it with the saw's maximum cut height.
• Check the largest blade width the saw can tension, not just the largest it can physically hold.
• Look at motor power in the manual and be realistic about hardwood versus softwood.
• Confirm the blade length your saw takes before you shop for blades.

Bandsaw size options at a glance

The table below pairs common saw classes with the blade lengths and widths on our spec sheet. It is a guide, not a promise of fit. Always confirm length and maximum blade width in your own manual.

The blade lengths come from the published specifications of the blades we compare, so they show what is actually sold for each class of saw.

Why blade fit matters as much as saw size

A saw is only as good at resawing as the blade you put on it. Width gives stiffness, so a wide blade resists wandering in a tall cut. Many 14 inch saws take a 93-1/2 in blade, but the 93-1/2 in blades in our data are only 1/4 in or 3/8 in wide, which suits general cutting and curves more than tall resaw cuts.

If you want to go wider, check what your saw can tension. One of our listed 131-1/2 in carbide blades is 3/4 in wide, and its listing says it fits saws that need that length and can properly tension a 3/4 in blade. That note applies to any wide blade: the saw has to be able to do its part.

For a closer look at width, tooth count and length, see our best band saw blade for resawing comparison. It lines up the options on one spec sheet.

What a smaller saw can and cannot do

A smaller saw is not off limits. It simply asks for more care. Our data includes a 1/2 in wide veneer blade in a 111 in length, which shows that narrower resaw blades exist for saws that cannot handle the widest options. Its listing gives a depth of cut of 1 to 8 inches in hardwood and 1 to 6 inches in softwood for kiln dried stock.

By contrast, a 3/4 in blade with 3 teeth per inch in our data is described as generally used for straight cuts in 6 to 10 inch hardwoods and 5 to 8 inch softwoods. Those figures are a useful reality check on how much height each blade is meant to handle.

On a smaller saw, keep your expectations in line with the blade and the frame. Take lighter passes, feed slowly and let the blade do the cutting. Forcing a board through is the quickest way to get a wavy cut.

Safety notes for resawing

Resawing puts a tall, narrow board against a moving blade, so a few habits matter.

Wear eye protection, since chips and dust fly in tall cuts. Wear hearing protection for long sessions, and a dust mask or collector hookup because resawing makes a lot of sawdust. Unplug the saw before changing blades or adjusting guides.

• Set the upper guide just above the board, close enough to support the blade but not touching the wood.
• Use a fence or point-fence setup and push sticks, and keep your fingers well clear of the blade path.
• Only run wood that is dry enough for the blade. One listing we compare warns against wet wood and logs unless dried to 10 percent.
• Make sure the board is stable on its edge, and support long boards on outfeed.

A simple way to decide

Pick the widest board you plan to cut, then confirm your saw can fit its height. Next, check the widest blade your saw can tension. If both numbers cover your needs, the saw is large enough.

If either one falls short, you have two paths: choose narrower stock and a narrower blade, or move up to a larger saw or a riser. Then use our blade comparison to find a length and width that suits the machine.

Frequently asked questions

Can a 12 inch bandsaw resaw at all?

Yes, for narrow stock and occasional jobs. Expect a smaller blade width and slower feeding, and check the manual for maximum cut height.

Does a riser block help with resawing?

It raises the cut height so the saw can take taller boards. It also changes the blade length you need, so confirm the new length before ordering.

Is motor power or saw size more important?

Both matter. Size sets the cut height and blade width, while motor power helps in dense hardwood. A strong motor cannot make up for a saw that cannot tension a wide blade.

Can I resaw wet or green wood?

Not on every blade. One blade listing we compare says not to use it on wet wood or logs unless dried to 10 percent, so check your blade's limits.
