This usually depends on the blade speed of your bandsaw (contained in your operator’s manual) and is expressed in linear feet per minute of operation. Saws with a rating of 4000 or less lfpm usually perform better with a blade with 4 teeth per inch.
Those blades usually have an overall length of 106 inches or less. Newer high-speed saws with a rating in excess of 4000 lfpm usually work best with 3 tpi blades that are more than 106 inches in length.
