Quoting from IBM-MAIN -

Your expectation is not correct. The length returned (both in R1 as the 
number of doublewords, or via EXTINFO) represents the amount of space that 
the system obtains. 

Particularly for program objects, it is often the case that the storage 
amount allotted is rounded up to 4K, which actually correlates to the fact 
that PDSE space allocation is typically in 4K mutiples. That rounding does 
not typically happen for load modules (in PDS).

===========================================
As LOAD provides the length (other than certain cases), I don't see how
anything else is easier.
