Granularity is

The more components in a system, the more flexible it is. In more general terms, the degree to which a volume of information is finely detailed.[3]
the level of detail of the organizational unit in information systems and is used to explain the difference between a system that, for example, treats a map as the information object and another system that treats the features within the datasets of the map as the information objects (i.e., at a more detailed level of granularity).[4]
