Q: What is Resourcestring max size and max number limitation? What is the maximum numbers of resourcestrings we have in Delphi application and what is the maximum length of resourcestring value we can have?

A: For the Windows platform it is documented here

STRINGTABLE resource
  stringID Unsigned 16-bit integer that identifies the resource.
  string One or more strings, enclosed in quotation marks. The string must be no longer than 4097 characters

Further, there's an error in Delphi:
