Static library size in iPA

How can I accurately calculate the contribution of a static library to the IPA size?

Most of the information (like this QA ) I can find is an IPA check for large media detection. I am curious to see which static libraries contribute more to IPA.

I looked at the file size DerivedData/{App + some id}/Build/Products/Profile-iphoneos/{some id}/lib{Static library}.a

, but I suspect it is larger than the actual size in the IPA.
