Estimate Solr index size

We have a customer with 1.5 billion objects to index. We know how many fields need to be indexed for each object, as well as the field size for each of them. We expect index replication to be set to at least 2. Is there a way to guesstimate the Solr index size? Actually, what we need to tell the customer is how many nodes they need in their cluster, which at this point we believe is going to be driven by the index size.


Any guidance is appreciated.
