How much space does RMAN need to restore a datafile?

Does anyone have a link or a resource that correctly, definitively, and authoritatively specifies that Recovery Manager needs (for example) 15 Gigabytes of free disk space to restore a 10 Gigabyte datafile?

We have learned that restoring a 15 GB datafile to its file system that has 23 GB available is a non-starter ... but we have not arrived at the correct proportion of necessary free space for data file restoration.

Any help would be appreciated
