What is the current size of Ethereum's state in bytes?

I am not asking about the size of the blockchain with blocks headers, transactions and receipts. I am looking for the size of all the structure that is stored under the State Root (merkle trie).

If you don't have exact number, could you give an approximate? Or any quick idea on how to calculate it?

The answer depends on which client you are running. There are more than 6 different implementations, but below are 2 for reference:

As of April 2021:

  • ~732GB for Geth (Go)
  • ~411GB for OpenEthereum (Rust)

This answer will of course become outdated, please refer to my source for these numbers here:
