Subject: Most efficient way to compute initramfs.img memory needs once uncompressed?

I'm desperately trying to find a good way to compute the memory required in terms of ramfs? 
This must work on all maintained distros that use dracut. (at least centos-6, fedora-25, ...) 

In other words, is there a simple/common way to compute the following command line parametters given an initramfs.img file? 
ramdisk_blocksize=1024 ramdisk_size=?????? 

- lsinitrd doesn't have this capacity 
- informations stored in the initramfs doesn't have this info 
- lsinitcpio has this capability but seems to be specific to archlinux. 

Regards,
