No, there is no general rule of thumb, since there is no direct correlation between a fixed index size and the demand for RAM.
There is no upper size limit for RAM imposed by Elasticsearch. JVM implementations imposes some restrictions, for heaps > 4g, garbage collecting the heap objects becomes challenging. This is true for all Java server applications.
