Like most "info hooks", this function returns a large definition array, defining one or more fields. Also as we would expect, there is a corresponding hook_field_info_alter() hook. In our case, we just have the one called dimensions. Let's look at each property in turn:

label and description specify the human-readable name and explanation of this field.

settings defines an array of configuration options for the field and their default values. These settings are fixed and after we create an instance of a field cannot be changed, so use with caution. Generally you only want field settings if changing the setting would affect how data gets saved.
