MapFileStats is a simple free utility to obtain executable binary size statistics derived from a “.map” file.

Use it to know which units contribute the most to an executable’s size, which DFMs are the largest, which units you have dependencies on but barely use in your executable, or merely to know exactly what gets into your executable.

You can integrate it into the Delphi IDE via the Tools menu, see the MapFileStats page for more details or to the download page and see for yourself!
