I have a fortran code which requires to be compiled with -r 8 option. It also requires to be linked with BLAS and LAPACK libraries. I thought of trying Intel MKL for this, but was not able to find if the size of real data types in MKL libararies.

What is the size of REAL in BLAS and LAPACK libraries in MKL ?

-r8 simply promotes default real to double precision. This matches the double precision functions in MKL. In addition, there has been optional support for double precision BLAS functions with single precision names for linux x86_64.
