You can also take the old blade and measure it with a tape measure. Or you can use a string to measure the length by mounting it in your saw after it has been unplugged from the power outlet. Or use this formula: (R1x 3.1416) + R2 x 3/1416) + (2 x C) = Length
R1 = the radius of the top wheel
R2 = the radius of the bottom wheel
C = the distance between the center of the top wheel and the bottom wheel.
You can check our reference guide or contact your saw manufacturer.
