I just got my e-mail newletter from Wood Mag and they had the following free tip for measuring blade length on a band saw. It sure beats tying a string around the wheels.

Figuring band saw blade length
How do you figure the length for a band saw that doesn't have a blade to measure from?
If you lost your band saw owner's manual and don't have a blade to measure from, or if you've added riser blocks, put this simple math formula to work to determine your tool's blade length:
Blade length = (2xA) + (3.14xB)
Key:
A= distance in inches between band saw wheel centers when the upper wheel is midway in its adjustment range
B= bandsaw wheel diameter
