Hi Robert, you can do this easily with a tool such as IBExpert. Just run
Services / Database Statistics and this is the result:

TableName Size Usage%
CUSTOMER 11,960,320 0.295
PARAMFIL 16,384 1 0.000
POSTCODES 3,903,012,864 96.335
POSTCODE_MISSING 16,384 1 3.000

I've removed a lot more detail such as number of records, pages, fill
size etc.
