measuring blower pulleys

I have read a number of threads on the sizes of the various pulleys out there. But I am confused where people are measuring the OD.

Some threads mention the belt surface or something like that. My calipers don't reach far enough into the body of the pulley to get anything accurate.

Is the measurement just the OD on the outside of the pulley?

Thanks, just trying to figure out what I have
