How can we derive the size of software product?

We can derive the size of the software product by counting the lines of code, included by a particular developer. Another method can be the “Functional Size Measurement”.

Software project size estimation is a very inexact science. I think many people will agree that it is foolish to try to do an accurate and detailed estimate of a software project because there’s typically so much uncertainty. In the old days, we used to use things like function points but that is known to be wildly inaccurate.

In today’s world, many software projects are moving to an Agile Project Management approach; and in an Agile environment, an estimate cannot be any more accurate than the requirements are known. For that reason, software estimation is typically limited to very imprecise estimates like story points.
